hello. i have a lenovo e431 that will not start unless i disconnect the battery and perform a power drain. on other units, that's all that needs to be done and they work, but on this one, once i restart, it goes right back to not booting, black screen and no beeps. i've also let the battery run out naturally and once i hook up the a/c, it'll boot once, but the minute i reboot, it goes right back to a black screen & no beeps. is it the battery? the MB battery? what needs to be replaced?

thanks!

hello again, i just spoke with the client and they say they've already changed the battery and it didn't help. what could be causing the need to power drain in order to boot?
