YOU WILL BREAK WARRANTY IF YOU FALLOW THIS INSTRUCTABLE
If you are not gentle and careful you might damage the internals of your machine farther.
GROUND YOURSELF BEFORE TOUCHING ANY OF THE INTERNAL PARTS! (place your hand on a large metal object, you only need to touch it for a few seconds)
Before you start you should be sure this really is the problem your laptop is having. HERE is a link to HP's site, try to see if you can still get your machine professionally fixed for free, better fix.
Basically if you have the fallowing problem this is for you: machine wont start after pressing power button, all lights will come on and HDD will spin and fan will start, but it shuts down after a few seconds and keeps doing this over and over, also no video on computer.
I know these model laptops also have a bad wifi problem, but this tut will not solve that.
