BIOS could not boot up my hard disk

**rave9200** · 02-11-2011

Recently, my girlfriend accidentally hibernate my laptop and then it won't boot up the right way again--all ended up on black screen with a cursor on the upper left corner.

My laptop is dv5-1070 and dual boot to windows 7 (64-bit) and windows vista (32-bit). I read some previous forums before, but I can't get it right. My bios version is F.21

My hardisk is in good condition...scanned it on other computers and it works fine. Can anyone help me to get my computer right again?

You will need to reset the cmos battery in your laptop, so that BIOS setting gets reset and after that the laptop will start to boot without any issues. Just take the cmos battery out for 1-2 minutes and after that re-seat it again in its place and then boot your laptop and check if it works or not. Hope that helps.
