Have a HP and the warrenty just expired, now my battery will not charge. I have used it on AC power 99% of the time, so it makes no sence to me. I watched a few youtube videos about going into device manager and uninstalling the battery mode, but no luck with that. I have 0 charge to the battery. Any Ideas...I am afraid to buy a new battery and then have it not stay charged also

After posting I decided to examine this issue more deeply and I'm going to have to confess that the issue doesn't appear to be as cut and dried as I said. It seems that heat is more likely to injure the battery than the power cycling which is now more intelligently managed than it was in the past. In short I think it is best to regard my answer as doubtful, but maybe sort of. Glad I could be of so much help:)

PS I still think the most likely case is that your battery died a young death, particularly if this happened gradually.

Leaving the battery in the laptop while it is constantly plugged into the wall will kill the battery, it will only charge so many times before it can recharge no more and with it constantly plugged in it goes through countless charging cycles, even though the cycle is short it still counts as a cycle. You should use it on battery until it really needs a recharge and only then recharge and then unplug it. From time to time you should also let the battery drain 100%.

If you prefer to use the laptop plugged in then physically remove the battery. If I were you I would just buy a new battery, it is probably dead, the new one will last longer if you do the above.

I was afraid I was going to get this answer. Any suggestions on reliable sites for replacement batteries, few I have looked at the cost is around 100-110.

thanks again
