Laptop fell down on the floor and will not start now

Problem description:

The laptop fell down on the floor and will not start now. The laptop turns on, the power LED comes on but nothing appears on the screen.

Possible cause:

Memory module disconnected from motherboard.

Possible troubleshooting steps and repair solution:

First of all, check the memory modules. It’s possible that the memory module poped out from the slot and the laptop will not start because it cannot detect any memory installed.

Try reconnecting the memory module. Simply remove it from the slot and install back. Test the laptop and find out if the problem is fixed.
