Problem solved. No charge.
What is the problem?
You should try opening it up and checking the cable attached to the hard drive, It may have come loose.
You can not make it much worse, it already will not boot up. What laptop is it?
I believe the hard drive is located in the bottom right hand corner, it can be removed be undoing the singular screw and taking off the cap.
what's wrong with it?
Find a company or someone whose job is to fix computers...they'll take out the hard disk and attach it to another computer maybe,and will then fix your problme
