The best way to charge any new battery is to charge it to fullest the first time fully and then drain the battery to full before charging the second time. You should drain your battery completely in order to get a proper backup.

My laptop will not work on the battery and i need to keep it plugged in although the battery say 100% charged, why


Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

Hi, I have eMachines E640-N833G25Nnks, P/N: LX.NA102.059, Model: NEW85, S/N: LXNA10205902804E2A1601. It is: proc: AMD Phenom II X3 Mobile Processor N830, graphics: ATI Mobility Radeon HD 4250, mem: 3GB,...


I Googled to see if there was any problems related to battery sensors, seems eMachines laptops don't have that problem, the laptop runs well while plugged in, so it's not internal circuitry, I believe it's a battery problem, as you say charging level has been decreasing progressively, try your battery on another laptop to see if the battery is the problem and just in case try a friend's battery on your laptop to completely eliminate doubts about battery sensors, if you don't have a friend with a similar laptop I would go the safe way and send the battery for replacement, if the store where you bought it is in the same country you should get the laptop there so they check out what's going on, if you live in a different country read the manual or click "eMachines customer support" to see if there's any tech support near your city, I still believe it's a battery problem.
Not I'm gonna give you some advice on taking care of your laptop's battery: - When you get new batteries make sure you charge them at least 12 hours before using it. - If you're not going to use your laptop in a while (one or two weeks) get the battery to full charge and then deattach it from the computer, put it back in if you're going to use it. - If using your battery periodically get it to full charge and deplete your battery's energy completely by using the computer until it turn's off itself and then recharge it completely again at least once a week.
If you have any questions, I'll be glad to help. Have a nice day.

Pasario 6500 laptop will not charge, charger is plugged in, turned on and laptop is running on mains power but it will not charge the battery


Most likely your battery stopped recharging. Depending on what type it is, and how old it is, it could be dead by now and needs replacing.
Most laptops can operate connected to their power supplies, even when the battery is taken out.
Some batteries need to be fully discharged for them to take a new charge and perform as new, up to a 1,000 times, according to their manufacturer's specs. Others have what's called a "memory effect". This prevents them from taking a full charge, especially when connected to the laptop almost 100% of the time, and using up some of their charge only ocassionally, when they are disconnected from their power supplies.
You can get replacement ones on eBay for less than the manufacturer's advertised price.
Good luck!

I would try another power supply, as the one you have may not be providing enough power to both run and charge the laptop.

  • two ways to charge the battery:
    • while the laptop is on
    • while using the laptop with a power cord, but it will take charging time when you are using the computer.
  • --if the problem persist, the battery may have a problem, called dell technical support and have the battery serial number for possible battery recall. or replacement

Acer aspire 4920 charging mechanism failed


Most laptops, as in 99%, have one board and everything is on it. They don't really have a power supply since the AC adpater provides DC voltage already. There is just a voltage divider that take the incomming voltage and changes it to the various voltages the machine needs. The charging mechanism is also on the mainboard. I've very seldom seen a seperate power or charging board in a laptop. Unfortunately since you've already replaced the battery and the ac adapter and since the adapter is powering the laptop then there is definitely a problem with the charging circuitry on the mainboard. This isn't something one can repair unless you start changing micro components and ICs on the board which isn't recommended. Looks like a new mainboard or a new laptop is in your future if you want it to run off battery.

Another option is to get an external battery that mimics your ac adapter but that wouldn't give you a very long run time compared to the internal battery.

Don't forget to rate my solution in your premium thread as FixYa if you think I helped solve your problem. Thanks.

I have a HP laptop. The battery will not charge. Do I need the battery to operate the machine?


Hi,

The laptop will operate with or without the battery as long as the AC adapter is plugged in. The purpose of the adapter is both to charge the battery and provide power to the laptop. This is of course assuming that everything else works and has no issue.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

It ia an acer aspire 3004 laptop. The battery charging % remins at 74% all the time and when I remove the power the lap top turnsoff completely.


Hello,

Well it surely shows that the battery is not providing backup to the laptop. There could be few reasons for the same defective and faulty battery is one of them.

However i will give you a step which you should try once and see if it makes any difference.

Method (Power cycle)

You need to remove the battery, adapter and any other device connected to the computer (May be any additional cards or any wires as for Ethernet or speakers or external mouse/keyboard).

Nothing should be connected at all.

Now Press and hold the power button for 25 seconds (It wont show anything). This is a step to release any static charges developed, which may surely caused the kind of issue you are facing.

Now connect the battery and the adapter and check whether it is charging the battery and provides you the backup.

The usual battery life is said to be 1 year. if you are using an older battery, kindly get the same checked as well.

Hope his will help. Please let me know what happens.

Regards
Sammy

Very short battery life on laptop currently lasts about 14 mins from being fully charged to empty


time to get a new battery. For future reference, do not use battery and AC at the same time b/c it will kill the battery. Use one or the other (unless battery is being charge).
