My apologies if this has been posted elsewhere; if so, I hope someone will point me in the direction of the current thread. Since upgrading from Vista HP, I'm getting "consider replacing your battery" and "There is a problem with your battery, so your computer might shut down suddenly" messages while plugged in and erroneous power readings and early shut down when running off battery. My battery is fine; I never had any trouble before the upgrade. I've found several threads elsewhere discussing the problem, but the proposed solutions (such as driver and BIOS updates) don't seem to be working for anyone. Is anyone else experiencing this problem? Has anyone had any success resolving it?
