I got an 8700g from e-bay yesterday, and it works beautifully, except for one problem.

When it's on battery, right in the middle of an operation like, say, exiting out of the browser, it'll just shut off. No warning, and the battery status will say 90%. However, when on the charger, it works like a champ.

I've put it through tests, trying things that happened when the unit shut off on battery, while it's on charger. This only happens on battery.

One thing I noticed was that the battery stayed on 85% while charging for quite some time. Oddly enough, though, the unit stayed on while on battery while I upgraded the OS through the desktop software.

My question is: does this sound like a battery problem? I've tried to check for things like loose battery doors, and so forth...nothing like that is going on. The good news is that the seller is sending a replacement battery, but it just seems odd that it would just shut off with no low battery warning, and that's the only thing that concerns me, but again, I put it through its paces on the adapter, with no problems.

I'm thinking maybe the battery is corrupt? Is it possible for it to give a "false read" and say it's 90% charged when it's really not?

Thanks in advance.
