My laptop started to shutdown automatically with no warning every time the battery runs out without giving me a warning that its shutting down. The fans and the hard drive and all just stop along with the monitor when it happens. It is then impossible to turn on the laptop even for a second without plugging it back in with the AC cord. I think it may have to do with me dropping it once from a foot in the air because it didn't do this before. I have a Dell 700M. Thanks for any help!
