So she dropped our dell studio 1558 and now doesn't boot. She looked online for answers and thinks the power button may have frayed and wont start because of the circuit wont complete. I tried hooking it up to my desktop by USB 2.0 to SATA but my computer wont recognize it or in computer engagement doesn't show either so I directly hooked it up to the computer and it still doesnt show a new hard drive anywhere I am looking. Am I doing something wrong or is the hard drive toast? any Ideas would help please respond asap, she has finals due tomorrow that weren't backed up.
