I have a 2 year old Acer Aspire Laptop with an apparent "dying" battery. (Battery is exhausted in an hour or so.) I am able, however, to recharge the battery and the computer works with both AC current and the old battery. I recently ordered a replacement battery (Amazon) and the battery does not charge. (Icon shows that the computer is 'plugged in' but NOT charging.) Again, I clarify when I use the old battery, the icon shows 'plugged in and charging'. I've tried many of the things suggest on the internet, (ie, battery calibration, uninstalling / installing device managers, etc.) ... but it doesn't affect the inability to charge the new battery. I live overseas ... and the battery was ordered while I was temporarily in the USA ... so it is not easy to return the battery via Amazon. Is there any chance that I might be able to get this new battery to function by carrying out some other procedures?? Feedback will be appreciated.
