10 **Better** cheap and easy upgrades for your old PC

In response to a submission on digg.com entitled ¡°10 cheap and easy upgrades for your old PC¡±, user gaqua posted a ¡°better¡± list in the comments that I found funny enough to want to give it its own post on my meaningless blog.

Here¡¯s a better list.

1 - Clean up your shit, dad. I¡¯m tired of coming over and finding a new toolbar on IE or Firefox every time. I¡¯m tired of thirty icons in the systray, half of which have some bizarre relevance to programs that are no longer installed. Go to add/remove programs, and remove anything you don¡¯t use in your Apple Powerbook G4 battery.

2 - Defrag that shit. 74% fragmented. SERIOUSLY? How is that even possible? I¡¯m scheduling this for every Wednesday night at 10pm dad. I know it¡¯s going to freak you out when it starts doing this all on its own but just leave it alone and let it do its magic.

3 - 512MB of RAM? Do you know how cheap RAM of VGP-BPS2C is? PC2700 DDR1? Oh my God¡­I think I might throw up. For $50 I can get you to 2GB of RAM. $50.

4 - I¡¯m installing Ad-Aware and Spybot Search & Destroy - your system has over 200 known spyware problems. I¡¯m fixing them. I¡¯m making this Inspiron 6000 Battery bulletproof. Don¡¯t fuck with it anymore. I¡¯m installing AVG anti-virus. It¡¯s going to ask you to update it - UPDATE IT WHEN IT ASKS.

5 - Holy shit I can¡¯t believe this - you¡¯re running XP without even SP1 installed. I¡¯m installing SP3 for D5318 Sony NP-BG1, Dad. It¡¯s a lot more secure. Jesus christ this is like the dark ages of computing.

6 - Oh fucking shit - 3 hours to download? What the fuck - you¡¯re still on that 512k DSL? Mom is paying for Cable! She¡¯s paying for Cable internet, Dad. I¡¯m going to unplug this wire from the DSL modem and plug it into the cable modem of A1175 A1079. Yeah. No it¡¯s very easy. And I¡¯m calling AT&T and canceling DSL. There, I just saved you $50 a month. And yeah, the internet is faster.

7 - Oh look 360tyj.com, you have a cutesy animated desktop background. Yeah, your celeron 1.6 GHz probably doesn¡¯t like that, especially with the 16MB integrated graphics. I¡¯m going to turn that off. I know, I know. But it¡¯s best for everyone.

HOLY SHIT YOUR COMPUTER IS FASTER NOW DAD. Please, tell everyone in the family that you ¡°don¡¯t know what he did but the computer is so much better, you should call him and have him come take a look, I¡¯m sure he¡¯d be happy to Latitude D600 battery!¡±

There¡¯s nothing I love more than that, dad. I love fixing Uncle Butch¡¯s disgusting laptop with the inexplicably stained keys and I love playing around with the disgusting beige eMachine that Aunt Patsy uses to send all those cool inspirational email forwards with pictures of kittens or penguins or koalas or pandas.

No, I understand. As the oldest and most computer knowledgeable of Latitude D620 battery , it¡¯s my responsibility. Just like Uncle Mason would help us all out if we got into legal trouble right? Well, if he weren¡¯t disbarred for fraud, I mean.

The Digital camera battery daily maintenance

At present, there are two types of digital camera batteries, professional lithium batteries and 5 AA batteries. The professional lithium battery is very light, high capacity, environmental protection, and no memory effect, but the price is expensive, and can¡¯t be use generally. Ni-Mh battery with high capacity, and discharge deeply, and durable to charge and discharge, short charge time and other obvious advantage. The most important of all is cheap and can be use generally.

The Original post from : http://www.digitalcamerabattery.us/

No matter what kind of Sony NP-BG1 battery, as long as it company sale with digital camera, the user manual will indicate the attention items, some manufacturers even print out a single user guide of Canon BP-511 battery, and charger. Those manual are the basic but useful maintain instruction, such as the charge method, charge time of the battery. It is necessary for the new users to take few times to read it.

Normal users don¡¯t have a professional bag to store the Kodak KLIC-5001 battery when use the digital camera, they usually put the battery randomly no matter the place is clean or wet after replace the battery. It is easy to dirty the battery, and contact with metal things, such as key, it also maybe wet, those are the enemy of battery.

Suggestion: User should find a professional position for the Casio NP-30 battery, and keep its clean. In order to avoid the power losing or any other problem, keep clean of battery two side touch point and battery cover, you can clean it with soft dry cloth when necessary.

If long time no need to use the digital camera, then you must take out the Fujifilm NP-40 battery from the camera and store it in dry and cool environment. Regarding the Ni-Mh battery, it should be discharged fully then store it or store it with power? The two different point, should adopt which one? A lot of people choose the former, but I think it is more reasonable to store the battery with power. Because according to the test, the best condition of storing a Ni-Mh Olympus Li-12b battery is with 80% power. This is due to the Ni-Mh battery discharge itself at 10-15% monthly. As you can as well, the new Ni-Mh battery always have power, it is the same reason.

Benefit analysis of recycling used batteries

In recent years, China's annual consumption for the production of Discount laptop battery to 120,000 tons of zinc, 200,000 tons of manganese dioxide, 20,000 tons of copper, there is a considerable amount of zinc chloride, graphite, asphalt, steel and other material. Mn and other resources need to go through mining, ore dressing, smelting and other processes was already consumed a large amount of resources, but also a certain amount of pollution generated.

Therefore, the used Laptop battery to deal with the sound and comprehensive utilization, environmental protection, the protection of significant resources to support the handling of used batteries imminent industry.

With the increase in battery consumption, improve recycling system, the experts predict that the battery recycling will lead to new business opportunities. China's production of dry batteries ranks first in the world 15 billion annual domestic consumption amounted to 7000 million.

Batteries will be used manganese, aluminum, mercury and other substances extracted, can create larger profits. Experts, to build a Dell XPS M1330 battery factory, although used to be about eight million yuan, but its revenue is very impressive, not only can enjoy the state's environmental protection enterprises preferential tax, at the same time every day as long as 100,000 to ensure the handling capacity of the battery can be 1.5-2 million profit. According to forecasts, the end of this century, China's annual consumption of the battery will reach 7.8 billion.

Recently, by the Beijing University of Science and Technology and Hebei Yixian of used batteries renewable joint treatment plant put into operation. The plant used Dell Inspiron 6400 battery scrap processing technology, is different from Japan's "wet", but also different from that of Switzerland's "dry", nor is it the joint law of wet and dry.

Its process as follows: material is broken down - chemical purification - waste water treatment, and ultimately can be recycled tin, zinc skin, such as copper material copper needle cap, and through access to high-quality electrolytic processing of zinc, manganese products, but also the recovery of mercury and iron by-product of red. The plant has a total investment of 7.8 million yuan, the design was to deal with 3,000 tons of used PowerBook G4 battery.

Supply of raw materials used battery prospects, Beijing 200 million each year battery consumption, for a total of 6,000 tons in 1999, recovered only 60 tons, the recovery rate of only 1%. 10,000 batteries a ton of weight, to achieve 3,000 tons, 100 million will need to used batteries, which means that Beijing's half used Dell laptop battery will be recycled and can be harmless treatment.

Why recycle the used batteries

Batteries are all over the place, we can see it in all kinds of electronic devices. A laptop battery is an electrochemical device to convert chemical energy to electrical energy to provide power to our electronic devices. The chemical used in battery will pollute the environment heavily if the batteries are improperly disposed of. In this article will show you how to safety disposed and recycled a used battery.

Environmental Hazards of Household Batteries

There are more and more batteries using in our household. A laptop battery is an electrochemical device to convert chemical energy to electrical energy to provide power to our electronic devices. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can heavily pollute the environment when batteries are improperly disposed of.

Batteries may produce the following environmental hazards:
Burning the Sony NP-BG1 batteries in public area will pollute the lakes and streams as the metals vaporize into the air when burned and it may cause burns or danger to eyes and skin.

Contribute to heavy metals that potentially may leach from solid waste landfills.

Batteries waste in riverside will pollute the water with strong acid. Animals or human drinking from these water will be harm by the pollution of the water.

What you can do before buying new batteries

So, do you wonder what you can do before buying the new Inspiron 1520 battery to prevent waste and lower the environmental impact of your hand. Here will provide some of the recommendation for you.

Buy batteries that have less mercury and heavy metals. The batteries now are reformulated to reduce the usage of mercury. Some batteries such as the alkaline inspiron 1525 battery have had about a 97 percent mercury reduction in the product. Newer alkaline batteries may contain about one-tenth the amount of mercury previously contained in the typical alkaline battery. Some alkaline batteries have zero-added mercury, and several mercury-free, heavy-duty, carbon-zinc batteries are on the market.

Try to not buy more batteries when you already have enough battery on hand. Most of the people likes to buy more batteries and store it at home but it will not be using in some time. This is a waste and will increase the risk of battery pollution in your house.

Consider using of rechargeable batteries. Rechargeable batteries as inspiron 1300 battery, inspiron b120 battery, inspiron b130 battery has longer life span and use fewer batteries. However rechargeable batteries still contain heavy metals such as nickel-cadmium. When disposing of rechargeable batteries, recycle if possible.

Electric vehicle battery support skills

1. Dont store the Electric vehicle battery in powerless

It is prohibited that store the laptop battery in a state of loss. State power loss is the failure to charge battery in time after use. Stored in the battery state of loss, it is prone to sulfate and lead sulfate crystals attached to the pole on the board, plug the electric ion channels, resulting in under-charging, the battery capacity decline. Idle state power loss the longer the more serious battery damage. Therefore, the battery should be charged fully once a month when not in use, so that the battery can keep in a good health state.

2. regular inspection in time

In the use of process, if the continued line of electric vehicles in a short period of time a sudden drop in mileage of more than ten kilometers, it is likely that the battery pack at least one battery cell appears broken, soft plate, plate active material shedding phenomenon, such as short-circuit . At this point, the battery should be repaired in time to the professional bodies to check, repair or distribution group. This can be relatively extended life Dell laptop battery to maximize cost savings.

3. avoid large current discharge

Electric cars at the starting line, manned, uphill, please use pedal power to help avoid a momentary high-current discharge. High-current discharge easily lead to lead sulfate crystallization, to the detriment of the physical properties of the laptop battery plate.

4. keeping right charging time

In the use of process, should be based on the actual situation accurately grasp the charging time, frequency and use of reference normal mileage situation and pay attention to the capacity of the battery manufacturers to provide the size of note, as well as matching the performance of the charger, the charge current to grasp the size of charging parameters Pavilion DV1000 battery HP Pavilion DV4000 battery such as frequency . Generally batteries are recharged at night, with an average charging time in about eight hours. If shallow discharge (charge mileage after a very short period), the battery will soon be full of and continue to charge-off charge will appear, and that leads to cell loss, fever, lower battery life. Therefore, in order to discharge the HP laptop battery depth of -70% to 60% when an electric charge the best, the actual use can be converted into cycling mileage, according to the need to charge the actual situation, to avoid charging damage.

5. prevent exposure

Electric vehicles is prohibited under the sun exposure. Environment temperature is too high will increase the internal pressure of the battery cell pressure limiting valve automatically opens, is a direct consequence of the loss of water to increase the Toshiba laoptop battery, and battery cell over-activity of water is bound to trigger a decline to speed up the plate to soften, charging shell body fever, from drum shell, deformation, such as a fatal injury.

6. avoid charging plug fever

Charger output plug loose contact will lead to the phenomenon of oxidation, such as charging plug fever, fever for too long will lead to short-circuit plug charging, direct damage to the Sony laptop battery charger, lead to unnecessary losses. So when found out that the situation should be promptly or replace the connector to remove oxides.

Zen and the Art of Laptop Battery Maintenance

Keep your notebook or netbook's power pack in tune

We all own more battery powered products than ever before, and in most cases those laptop batteries are rechargeable. Laptops, music players, phones - they all have rechargeable power packs, almost all of them using lithium.

These batteries don't last forever. No matter what you do, their capacity to hold charge will decline over time, typically down to 80 per cent after 12-18 months in the case of laptop batteries.

That's a range, not an absolute cut-off point, so how can we make these batteries last as long as possible? Ignoring the exceedingly rare risk of a fire, is there any way to ensure we get the best performance from our portable power supplies?

Follow some basic rules, and the answer is yes.

The model usage pattern is the mobile phone. Of all the rechargeable laptop batteries we've used, the ones in phones have always proved to retain their capacity longer than batteries in laptops, cameras and MP3 players. It takes a long time, generally speaking, for a phone battery to reach the point where no matter how long you charge it, it goes from full to empty in a very short space of time.

Contrast that with the netbook battery sitting next to us, which although less than a year old will discharge from full in under 20 minutes. That's with the netbook just sitting there, screen on, connected to the internet. It should last eight times that.

The keys to pa3420u-1brs battery longevity are regular usage and making sure cells are recharged before they become empty. Phone batteries typically take a couple of days to run down and tend not to be constantly on and off the charger during that period. Rather than waiting until the phone has so little power it switches off, most handset owners recharge their phones when they get a low-charge warning, usually around ten per cent capacity.

This ensures a steady, even cycle of charge and discharge, and if there's an operating condition lithium batteries respond well to it's regularity.

The 6t473 Laptop batteries won't, of course, give you two days of usage, so it's not necessarily practical to follow that charge-discharge-recharge pattern exactly, but you can get close. Make sure you regularly use your laptop on battery power. Don't work on it with it always plugged into the mains.

If you do use the mains as your primary power source - as you might well if the notebook's your main machine - at least make sure you use your laptop on HP Pavilion DV4000 battery power a couple of times a week. This is what we didn't do with the netbook. It has stayed attached to its AC adaptor for most of its life, with the battery barely being used.

The connected battery will charge to 100 per cent and then the battery pack's electronics will ensure the cells receive no further charge. At this point, the biggest threat to the battery is heat from the laptop's internals. Make sure your laptop's vents don't become covered. Beyond the heat generated by its operation, a laptop can safely be left connected to the mains.

There's no harm in removing the battery from a laptop that's going to stay connected to the mains for a while. Just make a note of the optimum HP Pavilion DV1000 battery storage conditions - more on this later - and don't inadvertently yank the power cable. With no battery, there's no back-up for your laptop's memory.

Apple machines are an exception, and others may be too: they auto-underclock the processor when the battery's removed, so despite being connected to the mains, they won't run at full strength. We think that's daft, but that's Apple for you.

When you use your laptop on PB995A battery power, make sure its charge drops to at least 80 per cent. But don't let it drop to zero. Depending on which operating system you use and how its power settings are configured, you'll get a low-power warning first and, later, your machine will sleep, hibernate or shut down.

At this point, your battery should still be charged to 5-10 per cent of its capacity, and you should now charge it, whether you want to continue working or not. If you're not going to be able to do so for some time, make sure you've saved your work and your laptop's shut down or hibernating rather than sleeping. These two modes turn the laptop off whereas sleeping just keeps it ticking over, but power is still being drained and you run the risk of emptying the battery.

Completely draining the battery is a no-no. Battery manufacturers and laptop makers say that it's a good idea to drain the HP Pavilion ZV5000 battery as far as the laptop will allow every so often and to then charge fully in order to synchronise the various capacity monitors within the power pack and the laptop. That ensures that your capacity read-outs are as accurate as they can be.

There seems to be a consensus that daily-use laptops don't really need this, and certainly not on even a monthly basis. Occasional-use laptops, on the other hand, may benefit.

Eking out the charge while your using your computer on Pavilion ZV5000 battery power is simply a matter of disabling Bluetooth and Wi-Fi if you don't need them, making sure your system spins down the hard drive when it's not required, and - perhaps best of all - dimming the screen's backlight.

How temperature affects a battery's capacity decline
Battery capacity after one year

If running to empty or never discharging at all are to be avoided, high temperatures are right out. Batteries' inevitable capacity decline can be slowed by keeping the inspiron 1150 battery cool

According to website Battery University, a battery kept full will see its capacity drop by six per cent after a year if it's kept at freezing point. Kept at 60¡ãC, however, the same battery will lose 40 per cent of its capacity to hold charge after just three months.

At 25¡ãC, you're looking at a 20 per cent capacity loss after one year. Since your working environment is likely to be less than 25¡ãC, the reduction will you see will be a little less than that, and by making sure the Toshiba PA3107U-1BRS battery is used regularly and evenly, you should be able to delay the point at which the battery has only 80 per cent of its starting capacity to 18 months or more.

Cycle logical: check your battery's recharge count in Mac OS X

Hot-running laptops will have the reverse effect, so if your notebook's like that, consider buying a cooling stand to help draw heat away from the machine and Compaq Presario V4000 battery. Don't keep your laptop in a hot car cabin, or in direct sunlight.

If your laptop's going to remain unused for a long period, keep it cool. Never freeze it, but sticking the battery in the fridge, for example, will prolong its life. Battery manufacturers recommend storing batteries with a charge level of 40-50 per cent.

If you do refrigerate a Pavilion ZD8000 battery, don't start using it as soon as you take it out again. Leave it several hours to warm up to room temperature first. Rapid warming could cause condensation, and you don't want moisture forming inside your battery pack or laptop.

If you have a spare battery pack handy, keep it cool and charged to 40-50 per cent of its maximum capacity until you're ready to take it on your travels. At that point, charge it up and use it as often as you use the other battery, so they both undergo regular charge and discharge cycles.

Charge Cycles Explained

Battery longevity - how long the battery lasts rather than how long it'll power a device from a full charge - is typically measured in cycles, with one cycle being a discharge from full to empty.

This doesn't need to happen all at once. A cycle is reached when 100 per cent of a Latitude D800 battery's potential capacity has been taken, even if it's charged up in the meantime. If you drain a battery by half one day, charge it back up, take 25 per cent the next day, charge it up again then drain it by a quarter on the third day, that's one cycle: 50 per cent + 25 per cent + 25 per cent.

That might suggest the best way to eke out cycles isn't to discharge the battery too much, but don't forget, lithium-based Dell laptop battery like to be used, not left on 100 per cent all the time.

Laptop makers typically say a machine's battery capacity will have declined to 80 per cent of its original capacity after 300-odd cycles.

How to Open a Laptop Battery & Replace the Lithium Ion

Laptop batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new laptop batteries are expensive, replacing the individual cells inside the battery casing can save a lot of money. However, rebuilding a battery sometimes does not work as expected, so it's important to be willing to purchase a new laptop battery if the procedure fails.

1. Allow the laptop battery to run down completely. Turn off your laptop, then remove the battery. Write down the model number located on your Latitude D800 battery to help identify the type of Li-ion replacement cells you need to purchase.

2. Split open a small section of the Latitude D800 battery pack (at the seam) with a screwdriver or craft knife. Continue to pry the plastic case loose moving around the outer edge until the entire top is free. This may take a bit of force.

3. Note the number of cells inside the case (usually four to eight). Write down the part number and voltage information printed on the Toshiba PA3107U-1BRS cell casings. Draw a diagram showing the arrangement of the cells and how they are connected, or take a few photos to help with reassembly.

4. Purchase the correct number and type replacement batteries from a local or online dealer, based on your battery model and cell specifications. Six Li-ion cells typically cost around $30 to $40.

5. Carefully remove each cell using a craft knife and wire cutters as necessary. Each Toshiba PA2487U battery pack is different, but the cells are usually wrapped in a plastic casing with metal contacts attached to one end. Lay the metal contacts, wires and casing material aside.

6. Use double-sided tape or a solder gun (only if necessary) to attach the metal contacts to the cells and circuit board. When finished, the old cells should be completely stripped (naked) and the new cells should look like the old ones as much as possible.

7. Place the new Discount laptop battery cells inside the case, referring to your diagram or photos if necessary. Glue the battery pack top back on. Charge the new battery for at least 24 hours before using it.

Keep an eye on the new battery while it charges for the first time. If the contacts are not connected properly, the battery could overheat and cause damage to the laptop.

How to replace battery cells inside laptop battery

In the last article, we have introduced "how to hack dead laptop battery" to our readers, but it is too simple. Now we write a detail article about " how to replace battery cells inside laptop battery".

At present, there are many articles about "how to purchase and use laptop battery" on the network , but there are too less article about "how to repaire laptop battery". For this reason, we decided to write a article about,laptop battery repair industry to help notebook users know what to do when laptop battery broken.

To notebook the battery is very important as the mobile work. The notebook become to desktop without laptop battery. There are battery cells and protection board in laptop battery inside. The batteries cells supply the power and the proctection panels protect the board safety when charging. Battery cells are consumable items, the capacity reduce in each using, which directly determine the quality of notebook batteries.

Notebook battery life short suddenly , cant work, laptop battery down suddenly (such as: battery capactiy suddenly reduce from 40% to 10% when working), laptop battery cant be fully charged,notebook battery cant be fully discharged (the notebook closed when the battery power state in 40% or more), the above cases may be caused by batteries capacity declining or batteries cells damage. Of course, there may be due to damage of the protection board, but this possibility is very small.

laptop battery cells

If you find that above failure happened to your notebook, it is necessary to check your laptop battery in laptop battery maintenance business. Now, let me introduce the whole process of laptop battery cells changing (for example Thinkpad T40 battery) .
First, we use professional equipment to detect the cause of the malfunction. There are many types equipment of Battery Fault Detection, such as: Texas Instruments products, MAX products, Ateml products, and even some personal home-made products. Most we use the commonly Texas Instruments (Texas) EV2300

Use professional equipment and related software to detect the cause of the malfunction

Once detected 92P1101 battery cells faulty , we are prepare to change the batteries cells for notebook battery.

Before the battery cells changing, We would like to tell you about the structure of the notebook battery.

The 92P1102 laptop battery are made up of three parts: batetry shell, battery cells and protection board.

In general, notebook battery can be divided into three parts: the shell, batteries and protection board¡£

Battery shell

The plate back has a serial EEPROM memory chips

Decrypt and unlock the protection board are two different works. Before you go into the battery management system you must decrypt the protection board, unlock the battery management system in order to change the parameters of the battery and use of information. If you only change batteries cells without unlock, you can not achieve satisfactory results (for example: the battery can only charge to the state "the last full charge capacity", the battery maintenance management information will be displayed the charged number)
We use professional equipment and related software to unlock and decrypt the protection board. Of course, you must choose the appropriate equipment by 92P1087 battery management chip design.

If the protection board hardware damaged , we would also use oscilloscope, multimeter and logic analyzer

After the deal with the batteries protection board , let me introduce the method to choose the right cells. We must use sub-meter cabinet and the internal resistance to check batteries capacity resistance, separation voltage, select out all specs of parameters for comparison with similar groups. Also the thinkpad R50 battery thinkpad T41 battery thinkpad T42 battery thinkpad T43 battery is the same battery cells.

Select the similar cells to make a battery group

Then we will use the spot-welding and Nickel sheet to joint the batteries cells together.

After unlock and decrypt the protection board, connect the battery cells group. We can assemble the shell protection board and cells together.

During the assemble, you must take high attention. The steps is also suitable for IBM 40Y6795 40Y6797 40Y6799

After doing the above steps, the battery cells changing is compeleted. The repaired battery quality is the new battery in most function, so you must calibrate it first. Generally, you should fully charged in 1o hours then full discharge it 2-3 times.
