I have this strange problem on the acer aspire one d250. It happened already once before, stayed for about two weeks, and then "fixed itself".

The problem is as follows: the battery can't seem to get fully charged; ie the indicator is stuck at about 90% (it's probably not a software problem -- I have ArchLinux and Windows 7 installed and both report exactly the same) and it never passes that value, but it still shows the status as "charging" (I tried everything I could think of -- leaving it charging for extremely long amounts of time, doing a few complete charge-recharge cycles, removing/reinserting the battery, cleaning the connectors, even updating the BIOS, etc., and nothing helped).

Also, when it is getting charged, it charges pretty fast until about 70% and then progresses extremely slowly.

The battery holds the charge that appears on the battery indicator normally. Just can't get the battery to charge fully -- I can't get it past the 90%.

At first I thought this would be a simple battery failure (even if the computer is not that old, about 6-7 months), but as I mentioned it happened once before, and then one day it fixed itself.

I tried contacting Acer about this, but the support was not helpful, completely stupid, it seemed like they used canned responses, the usual.

Any thoughts on how to fix this?
