Hi, I have a similar problem. I have two different notebook, in one of that the hard drive is broken. I tried taking the hard drive from the other pc and I replaced it, but I think I did a bad thing. Now I have black screen in each Notebook. What can I do? Thanks for all the support.
What did you do to verify that the hard drive from the first notebook is broken? Maybe the problem is the motherboard instead (which would explain why the other hard drive did not work).
Are you saying that you swapped them back to their original locations, and the "good" one no longer works either?
Do you get any signs of life at all? E.g. do you get the brand logo flashing on the screen, and *then* it goes black? Or does it just stay completely black? Does the power indicator light up?
Please provide additional details describing what you did, what you're seeing, and what troubleshooting you've already attempted (if any), step by step, for each notebook.
