Answer : Problem: The laptop does not start/ nothing happening on the screen

If none of those methods worked, then it's possible it's a motherboard issue.  If it's still under warranty, I would suggest calling Acer and gettign a replacement mobo to install to see if that fixes the problem.

Other possibilities are a dead CPU or BIOS (which is fixed with a motherboard replacement).  not being abel to run diagnostics makes it hard to pinpoint.
