Customre Reviews :

this Dell laptop battery is a nightmare. i bought 2 defective ones in a row and now dell will only refund one of them. the first one didn’t charge at all. after 2 weeks, the second one doesn’t charge past 5% of its capability. Dell will not refund me for the first one because their agents never connected me to the right # after I purchased the second one. Now i am over the 21 days. Dell has problems.

This battery only lasts a few months when I checked the price for a replacement I got shocked. I will try other batteries not from dell and check quality and price, maybe I can get the same performance as the oem but without wasting more money.

Choose suitable software for you laptop

December 29th, 2009

 

As with a desktop machine, it’s easy to end up paying more than you need for a package because it’s been buffed up with bloated software. You will, however, need an operating system, and the overwhelming majority of laptops use Microsoft Windows in some guise Presario R3000 Battery. Linux hasn’t really made inroads into the portable market as yet, and thus Windows XP Home or Professional will more than likely be bundled in.

Some leave it at that, others will include one or more of the following: DVD playback software (useful, but not that expensive to buy), anti-virus package (never to be sniffed at), some form of office package (if it’s Microsoft Office, that accounts for much of the price at Presario M2000 Battery, while the likes of Ability Office barely dent it) and CD/DVD burning software (the bundled stuff is generally quite limited, but enough to do what the majority of people need it to do).

If a portable machine goes awry, it costs a great deal more to fix than a desktop PC Dell Inspiron 5100 Battery. For that reason it’s worth looking into warranty packages, although don’t instantly snap up the one that your retailer is offering you. Shop around some third party services and see if you can get a better deal.

Hopefully, all of that has given you some useful pointers as to what to look out for. The usual rules should apply when you do finally go shopping though: research your purchase carefully, ask as many questions of your retailer as you need and make sure you pick the machine you want Toshiba PA3535U-1BRS, not the one they want to sell you. Oh, and don’t forget to check out the machines we’ve tested at IT Reviews.

why laptop battery suddenly stop discharging

macbook

Maybe we all face this situation : Some times we should travel to some place as the business or holiday. You know the 12 hours or more journey time is too wearily. So we like enjoy ourself with our laptop to watch movie or play game. Suddenlly the Dell Latitude D620 Battery stop dischargging in the 70% power state or more. You maybe very confuse about this : maybe some problem with my laptop or my laptop dead. In fact most of them are caused by the temperature or the over-Current.

Most laptop batteries have the protection circuit. When the laptop battery temperature is too high or discharge current is too large, out of laptop battery protection circuit action standards. Thus causing the Dell Latitude D600 Battery power automatically stop discharging and force the issue.

The most common situation is that laptop battery is running at full speed . The Dell Inspiron 710m Battery current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery. D0 not panic in that case. You only used to disconnect peripherals and wait about 10 minutes, then you can reboot the machine.

There is also a common situation : using the battery in a hot environment and high-load operation, , so that the ambient temperature plus the heat generated by the battery self-discharge Dell Inspiron 640m Battery protection circuit may exceed the preset temperature, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation.

Encountered such a situation should remove the batteries placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium Dell TC030 Dell PC764 battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment and high-load operation.

Microsoft program manager Lusidunpa Na Beike (Ruston Panabaker) Tuesday said the system, compared with WindowsVista, in Windows7, the laptop battery life time will be increased by 10% to 20%. Tuesday, Panabeike have been demonstrated, using two of the same model (the operating system different) laptop playing DVD. Demonstration results showed that running Windows7 notebook battery life than running Vista laptop Apple battery life longer by 20%.

Windows 7 is more energy-efficient than Vista

Overall, when users watch DVD through the laptop when the laptop battery life under Windows7 be increased by 10% to 20%. Panabeike said it was a great performance.

Last week, has been reported that the use of Windows7 operating system, Internet this Toshiba laptop battery life decreased by 1 / 3. Focus on the laptop reported “Laptop” magazine this week that Toshiba, the Internet has been tested, the results of the use of the Internet after Windows7 reduce the time of the battery life of 2.5 hours. In the XP system, the battery life of 9 hours, 24 minutes, while Windows7 only 6 hours 53 minutes.

According to Toms Hardware site testing, the XP system, the Acer AcerAspireOne access to this Sony laptop battery life is 8 hours and 28 minutes, while in Windows 7, under 5 hours, 54 minutes, the same reduction of 2.5 hours.

Re-understand notebook lithium battery maintenance

Re-understand notebook lithium battery maintenance

Li-ion batteries in a life cycle in general can be 300 to 500 times charge-discharge. So many people think that, as long as using less battery, so that you can to a certain extent, played a role in extending battery life. But they did ignore the original Dell Inspiron E1705 Battery that the physical nature of the end when the battery off the assembly line, it’s internal life, the clock will then start walking.

So even if you do not set aside the battery, lithium Dell Latitude D510 Battery life was only two to three years you can come to an end of. Battery capacity caused by reasons for the decline was due to oxidation caused by the battery internal resistance increases. When the electrolytic cell resistance reaches a certain point, although this time the battery still be full of electricity, but the battery has been unable to release the stored electricity.

Caused by lithium LIFEBOOK T4010 battery is the speed of this aging temperature and set aside when the charge state of preservation decision. I will give a table to illustrate the different situations of these two factors, the impact on the battery capacity.

Can be seen from the table, high charge state and the high temperature accelerated the decline in Lifebook T4220 battery capacity. Therefore, if possible, as far as possible, after the battery charge to 40% placed in a cool place to save. This allows the preservation of a long period, the battery protection circuit is in its working state. And if the battery is fully charged, will be placed at high temperatures, which will cause great damage to the battery, the table has also been seen, charge 100% in the 60 ° C environmental conservation, 3 months after the battery capacity fell by 40% .

Therefore, how to save the battery solved the issue, but also leads to another focus of everyone has been argued, that is when we use a fixed power supply when there is a need to remove the Apple A1148 battery? Before the resolution of this question let us first analyze the use of fixed power supply when the battery placed in a computer environment in which … … at this time due to charge notebook computers role in protection circuit, so that the battery remained at 100% of full power state, and this When the battery in which the ambient temperature between 25-30 ° C, at least, if the hot weather, this temperature will be higher, then from the table, you should be very natural to come to a conclusion that it is so to do this would actually damage the battery, causing a decline in its capacity.

But despite the use of laptop computers, high-temperature will bring damage to the Apple A1175 battery. But Qudiao battery, use only a fixed supply, there will still some danger that dust and moisture will cause some damage to the battery, while the use of notebook computers in order to avoid a sudden power notebook computers may cause damage, so Manufacturers generally warn users not to remove the battery. Of course, this result will be naturally imagined, your battery as often in such a relatively poor environment, it will not be long over, and then you will need to go to repair center to replace the battery, this way, the benefit of course, is a manufacturer.

Finally we spotlight a lithium battery that is exactly how a reasonable charge and discharge this issue. For the lithium battery is best for partial discharge, rather than fully discharged, and to as much as possible to avoid frequent full discharges. Regular Apple A1185 battery too low discharge of the result can only be scrapped so that the battery in advance, because if the battery into every cell of 2.5 volts below the battery’s internal safety circuitry will be switched on, this time the battery will become some bad spent. Therefore, in order to avoid such situations from occurring, do not save the battery power before its release was erased, but rather a number of electric charge in the store before, and again before the first fully charged.

All in all, in order not to make your premature loss of the role of the battery, then the use of normal, you should try to comply with the following principles:

A. avoid full discharge, and often for lithium batteries. The repeated arbitrarily rechargeable lithium Toshiba PA3331U-1BRS battery damage is very small, almost negligible.

B. will need to keep hold of lithium batteries placed in the shade, remember not to put in the refrigerator. Avoid placing hot car, such as a long time to save the battery charge to 40% in place.

C. most of the time if you are using a fixed power supply, please remove the batteries placed in the shade.

D. no need to purchase spare lithium batteries for storage, so this piece is actually a waste of Toshiba PA3356U-3BRSbattery.

Battery is brought to use, as long as the attention to rational use and preservation methods, there is no need to care for their excessive, making it possible for its owners contribute more to performance is the most important.

Laptop battery CAUTION AND USAGE

Laptop battery CAUTION AND USAGE

http://www.laptops-battery.co.uk/ Found some laptop battery caution and usage in the internet, and I share the tips to our readers.

When laptop battery is not used normally, battery and battery device would be damaged.

New battery must be charged by specific charger.

Keep Dell laptop battery dry and be ventilative.

There is organic flammable in battery. If it is not used normally, it will be broke, leaking water, or too hot. These will cause battery damaged perpetually. There is safe protection device inside the battery.

Do not use Inspiron E1405 Battery near the fire, stove or the place in a temperature higher than 80οC

The battery safe protection parameter and index would be damaged if battery is in the water. Then the Latitude D830 Battery can not work regularly. Finally the battery might be too hot, get fire or explode.

Don’t weld the battery with flat soldering because soldering melts battery insulator and damages safety circuit.

Don’t extrude the laptop battery with heavy object or the battery might be out of shape.

If the battery is connected in reverse terminal, the battery would be too hot, get fire or be damaged.

Some functions of the Latitude D820 Battery can not be used if the pack is not working in a specific machine. And the battery life would be shortened.

If not using the specific adapter or change the specific adapter parameter, the battery would be too hot, get fire or explode.

Once the Sony VGP-BPS9/B battery is found having problems, stop using it immediately.

laptop battery can not charge and dischage

Generally, we said our laptop battery dead means that : the battery can not charge or discharge. The laptop battery can not work after used for some months most caused by the problem. Also sometimes the battery suddenly can not be recognized by machine. This is the adapter or mohterboard problem (espacially in dell laptop battery).

To second problem we only can change the adapter or motherboard. So http://www.battery4.us will talk some useful tips about the reason and solution to the “battery can not charge and discharge” for you.

The laptop battery can not discharge

Laptop battery can not discharge Reason:

  1. The laptop battery after the storage using and the life decay;
  2. Lacking charge or not be charged;
  3. Ambient temperature is too low;
  4. Discharge efficient less, such as the large current discharge cause voltage sharp drop to 0, then electricity can not be released
  5. The Toshiba PA3399U-2BRS battery has been in over-discharge protection.

Laptop battery can not discharge Solution:

  1. The Dell Inspiron 1525 Battery during storage should take a monthly charge and discharge;
  2. Charge the battery at 10% state;
  3. Use in a normal environment;
  4. Use proper adapter of the machine.
  5. Place it in icebox for about 12 hours and cool place 3-5 days to unlock the protection

The laptop battery can not charge

Laptop battery can not charge Reason:

  1. The Inspiron E1505 Battery in zero voltage;
  2. charger failure, no output current;
  3. External factors have led to the charging efficiency is too low (such as low or high temperature).

Laptop battery can not charge Solution:

  1. Check charger output voltage and current;
  2. Check the laptop battery charger output contacts is good or not
  3. Charge the battery with 1.5 times the maximum voltage of the battery, 1.5C high current charging, active the Sony VGP-BPS8 battery . (Only when the battery can not charge, use this method)

In the end, http://www.battery4.us wish you have a good Christmas Day.

Battery recycle

December 16th, 2009

Battery recycle

Battery is generally cylindrical in shape with two terminals, one positive electrode and one negative electrode that conduct electricity along with a substance called electrolyte, that works on the electrodes, chemically and help convert into electrical energy. There is a copper wire that connects the two electrodes. Materials that are used in batteries are carbon, alkaline, chlorine, lithium ion, lead, nickel, sodium, silicon, copper, etc.

Batteries are classified into two- Dry cells and wet cells. The wet cell batteries are also termed storage battery ( VGP-BPS5) as they can be recharged as many times as possible. Batteries are also divided as rechargeable and non-rechargeable or disposable batteries. The second type is again termed as primary cells, used till the chemical that produce the electrical current supply is fully consumed, at which point the battery is not needed anymore. These types of batteries are used very commonly in small and portable piece of equipments that drain low current.

The other type is rechargeable or in other words secondary Dell Latitude D800 Battery cells that can be “refueled” even after being completely consumed. For recharging, these batteries need some external help from devices as chargers or re-chargers.

In the present world due to the development of science and technology almost everything (papers, plastics, Inspiron E1505 Battery, aluminum, etc.) can be recycled without wasting it by just throwing it after use. Thus we see that recycling is a procedure by which waste products are recovered for reusing, which is also known as waste management.

Laptop Battery recycling falls under electronic waste or e-waste. Here any discarded, broken or unwanted electrical or electronic equipments, containing toxic materials are recycled for further use. Batteries like, nickel-cadmium, lead, lithium batteries are made to reuse as the chemicals present in them can cause harm to the environment if allowed to stay long in open air after being discarded by the users. Moreover batteries are regarded as the most expensive energy source and their production requires much valuable recourse, so they are recycled so as to restore those valuable materials from those old and used batteries through battery recyling.

Cadmium is a heavy metal and can cause pollution if burned or cremated. To avoid lead pollution lead-aced batteries are processed. This program is considered to be highly successful. Lithium-ion Latitude D400 Battery can be very dangerous if exposed to high temperature or sunlight, it can ignite or explode. Therefore battery recycling is a must if we want to protect our environment.

The Recycling Process:

First of all, the batteries to be recycled are sorted according to chemistries such as nickel-cadmium, nickel-metal-hydride, lithium Sony VGP-BPS9A/B , alkaline etc. The combustible material, such as plastics and insulation, is then removed with a gas fired thermal oxidizer, which is the first step in the recycling process. Most recycling plants have scrubbers where the gases from the thermal oxidizer are neutralized to remove pollutants, producing clean, naked cells that contain precious metal content.

The metal in the inspiron 6400 batteries are then heated to liquefy, after they have been hacked into little pieces. Black slag left by burned out non-metallic substances are scraped off with a slag arm, and the different alloys that settle according to weight are skimmed off. Some plants pour the liquid metals directly into (65 pounds) or ‘hogs’ (2000 pounds) without separating on site, which are then shipped to metal recovery plants to produce nickel, chromium and iron re-melt alloy for the manufacturing of other metal products.

State and Federal Regulations in the United States:

The Mercury-Containing and Rechargeable Battery Management Act was passed in 1996 by the U.S. Congress which requires regulated batteries such as Ni-CD batteries and sealed lead-acid batteries to:
1. be easily removable from consumer products to make VGP-BPS9/B easier to recover them for recycling
2. include in the label the battery chemistry, the “three chasing arrows” symbol, and a phrase that instructs users to properly recycle or dispose the battery
3. provide national uniformity in collection, storage, and transport
4. phase out the use of certain mercury-containing batteries

By recycling batteries the environment is not being polluted nearly as much, many natural resources are saved due to the rechargeable laitude d620 batteries also. There is a large variety of websites on the Internet with more quality information on recycling batteries.

How to made a wooden keyboard

December 13th, 2009

keyboard

This wooden keyboard enclosure came not so much from a desire to make something out of wood, but wanting a custom keyboard case, but from wanting a slightly smaller keyboard case for a keyboard with the numeric keypad cut off.

Maybe you’d like to match the wood of your desk to your Inspiron 1521 Battery  keyboard. Maybe you need just the right look for your steampunk workshop. Either way, with this tutorial, you can craft a wooden case for your keyboard.

The solution is to cut the numeric keypad off an otherwise regular keyboard. Of course, that’s not as trivial as it sounds. At left you can see some various layers of the Inspiron 1526 Battery keyboard, arranged after I cut it apart. There are vital interconnects under the keypad that the keyboard would not function without. Also, the PCB attached to the foil with all the traces on it also connects to the right side.

My approach is to take the circuitry from under the right side of the keyboard, and just fold it under the page up/down and cursor keys. The foil with all the traces on it is flexible enough that you can get away with doing that.

A big challenge with making a wooden case is to cut a nice bezel for the Inspiron 1721 Battery keyboard. I traced the shape of the bezel from my donor keyboard onto a piece of plywood.

tracing

The next step was to cut out the openings with a scrollsaw. Its one of the few things where a scrollsaw is a vital tool. A bandsaw would not work because the blade can’t be threaded through the openings to cut the insides.

scrollsawing

Although I was careful to try to get all my edges straight with the scroll saw, they still had a bit of hand-sketched waviness to them. But then I had the idea of using my router table to clean up the long edges of Inspiron 1720 Battery. By sliding my plywood against the fence, the router will cut a straight edge inside one of the cutouts.

I should have thought of this technique before I cut the holes with the scrollsaw. I would have cut them much less carefully, and a little undersize, knowing that I’d get it all perfectly cleaned up with the router afterwrds.

Checking the fit of the keyboard bezel. The bezel is still oversized all around the edges. Its kind of neat how it looks with so much flat surface around the Sony VGP-BPS8 keys. If Bang & Olufsen made a computer keyboard, it would probably look a bit like that.

The keyboard itself is mounted on a piece of plywood. This is trickier than it looks.

The keyboard has some spacers under it to give it support. I decided that the bottom of my keyboard case is to lie flat on the desk surface, so that I have some interior space to fold the contact foil and PCB under the keys on the Lenovo 40y6797 right side.

Here’s the right side, with the foil folded under. Getting the keyboard to the point where the keys would line up, and be against the contact foil and backing sheet metal took a lot of iteration. If found that if I didn’t get it exactly right, the keys would feel like they hit a hard bottom, because they were impacting against their plastic guide instead of the rubber dome that pushes the pieces of foil together.

Based on how the bezel rested on the keyboard, I measured its angle, and cut wedges out of maple for the sides, and pieces for the front and back of the ThinkPad R40 Battery keyboard. I glued these against the bezel using some spring clamps

I also made a cutout for the keyboard cable’s rubber strain relief to fit into.

Next I screwed the top an bottom parts of my keyboard case together and trimmed off the excess on the table saw. I trimmed it such that I also trimmed not just the plywood, but my wood sides as well, to get all the pieces exactly flush with each other.

Here’s the Pavilion dv9000 Battery keyboard after trimming. Its very boxy and rectangular, perhaps reminiscent of an early 1980s Volker-Craig VC303 terminal – the kind with a housing made out of rectangular bent sheet metal.

After a bit of sanding, and five liberal coats of varnish, and the keyboard has some nice round edges to it now.
