My friend has laptop and he told me that his motherboard is dead. How to check does it is dead and if is dead will be as easy to replace it as in desktop pc?

If you can't get it to POST after going through this checklist - http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

then the motherboard is probably dead. They are pretty easy to replace if you've done it before.
