|If you left your notebook on the bed running, unfortunately you may have blocked the ventilation openings on the bottom and sides of the notebook causing overheating. |
Something may have burned inside. Motherboard may have been damaged, part of it, at least.
Other than that, you cannot interchange hard drives between notebooks ( PCs ) and expect them to work. You have to install Windows from scratch after hardrrive change.
What you can do now: Let the notebook cool down to room temperature. Remove battery and re-install the original hard disk.
Re-insert battery. Plug the power adapter to notebook and to the wall power outlet. Wait a couple of minutes and press the power button of your notebook.
I hope it runs.
