Its sometimes a driver problem due to it will not charge the battery.
Here could be an update
for your problem.

If not contact ACER support they will be glad to help you out.

Good luck.

I had a similar problem with my Acer Aspire after I got a replacement battery about 6 months ago.
I was told to disconnect the laptop, turn it off, disconnect the battery, then press the power button for 30 seconds to reset the charging circuit.

I did this, but it didn't work any better. I thought that since my charger seems to run the computer, but it says 0% Available (plugged in, charging) that there was something wrong with the battery.

So, I contacted the manufacturer of the battery and they said they would refund my money within 7 days after receipt, and they gave me an RMA number for the return on the address label.

I, also, got the battery from Ebay.

Since your problem is that the battery icon with a red X over it says 0%, I would say that maybe the battery is bad, or maybe the battery is not connected very well at the contacts. Maybe blow the contacts off with compressed air in order to clean any dust which may be on it.

I would maybe try another battery to try to see if the charging circuit is bad on the laptop.

If another battery doesn't work, then the charging circuit between the laptop and the battery may be faulty.

Good luck on this repair.

your battery may have become "Imprinted".
Run the system on battery until the battery is completely dead, then fully recharge it as far as it will charge, then exhaust the battery again. If the battery doesn't recover it's full capacity, then contact Acer for a replacement as the battery should have a 1 year warranty

Sounds to me like the transformer circuit that enables the batery to charge. If you have bought your machine within the last 12 months it should still be covered by warranty so go back to the supplier. If not covered I wouod still try as it is not beyond reasonable expecations that the machine will operate perfectly in very way for more than 1 year.

If the battery is more than one year old, or has been often used with the power supply plugged in, it might have degraded.

Sometimes you can regenerate it to some lesser extent by completely draining it and recharging overnight (but that's apparently what you already did).

So I'm afraid you will have to replace it.

A new Acer battery (4400 mAh) should get you at least three hours life, and up to six hours by being real careful (lowest screen luminosity, no disk activity, no heavy usage: e.g., vanilla word processing)

Don't buy a new battery! I was about to and then I found out their was a BIOS problem. I downloaded the update, installed in less than 5 min. The battery charged PERFECTLY

You need to ditch the battery on the laptop. It is causing the issue. This is a know problem with this laptop.

Sounds like it may be the FSB. I had the same sort of problem, though my Aspire was only a few months old and therefore covered under Acer's warranty, but I also have after sales repair insurance too. Either way, I would strongly suggest that you get an engineer to take a look

google it

are you sure the battery is good? How old is the system and battery? Do you have any way to check voltage at the battery terminals?
