The battery may be getting old/depleted OR some of the cells in the battery may be dead/malfunctioning.
The battery is probably still worth using for a while yet, though it will last a much shorter time than usual.
Alternatively, you could get a new replacement battery.

A remote possibility is that you are using a wrong charger for the laptop - it does not supply enough power to the battery. Please confirm it is correctly rated.
All the best!

I have an Acer 7736Z the battery isn't charging. The BIOS on the acer support website give me version 2.10 which doesn't seem to match the directions given from previous questions and solution


If your battery will not charge, you need to run a test on some components on the laptop. The battery, the charger and the laptop itself. Once you detect the faulty conponent then you replace it with a new one.

To test the battery:
1.Power off the laptop,
2.Take out the battery,
3.Insert it in another laptop,
4.Check of it will charge,

If the battery holds a charge there, then it means the problem is not from the battery, but if it does not hold a charge, then it means the battery is defective and need to be replaced with a new one.

To test the charger:
1.Unplug the charger from the present laptop,
2.Connect it to another laptop to see if it will charge.

If it charges the laptop, then it means the charger is alright, and if it does not charge the laptop, then it means the charger is bad and need to be replaced.

To test the laptop:
1.Turn off the laptop,
2.Disconnect your present charger,
3.Remove your present battery pack,
4.Insert a well tested battery into the laptop,
5.Connect a well tested charger to the laptop.

If it powers on, then it and charges, then it means the laptop is working fine, but if it does not charge, then it means the connection port of the laptop is bad.Hope this information was helpful.

What will happen if the battery in your laptop is not fully charging


That would mean your battery is dying and you need to go buy a new battery for your laptop. You can buy new batterys for around $40
Find a store that sells laptop parts or go online look on amazon or next tag also when you get your new battery plugin your laptop charge your new battery so it has a full charge.Then when it is done charging unplug it and use the battery until it dies, then plug it in again to recharge it never leave it plugged in if it is fully charged for long periods.if you are using your laptop at home you can pull out the battery and use it when its plugged into the wall this will help to extend your battery life just make sure you have a fully charged battery before leaving your house. always unplug your your laptop when its is fully charged this will also extend your battery life for along time

Acer netbook battery cannot reach 100% charge?


As rechargeable batteries age they build up what is called a 'memory' or a 'charge memory'....

Let me explain how this works...you have a new battery and you run your laptop normally until it hits 15% charge then you charge it up and use it again until about 15% then charge it again....with the charge only dropping to 15% the battery builds up a 'memory' of that over a period of time (usually over at least a year up to a couple years) and then your battery's maximum capacity is no longer 100%. Same thing happens if you dont charge it fully each time, after a while it becomes incapable of taking a full charge.

What you can do to stop that in the future....when you get a new battery every now and then run its charge down to 1% then charge it to maximum. By doing that on a regular basis you help make sure the battery remembers its full charge capacity.

I replaced motherboard on nc6400 new battery new charger but still not charging what can be the reason???? the laptop work on AC power Work on the new battery i charged it on other computer????


Because of BIOS. Basic Input/Output System.
Battery has 'lost track', of what the battery state of charge is.

Try Recalibrate BIOS

Ive replaced my laptop battery.......it does not recognise...or c


since putting back the old ones charges the battery, then the charger unit is good. its best to replace the old battery pack with the same rating. the charger might be having some difficulty due to a higher rating of the new one.
