My laptop stopped working after i put down on couch not hard but not soft either. I was getting it to boot to having the mouse pointer which was movable over a black screen. Tried to to a system recovery but it says there's an error then you hit a button whichsends me to a dos screen and says there is no boot up device. Anyone with help would be great.
The "jolt" from not putting it down gently may have damaged the hard drive. Test it with the drive manufacturer's diagnostic software for DOS which loads from a bootable CD. The links are here: http://www.tacktech.com/display.cfm?ttid=287
