Elitebook Workstation 8540w blinking caps lock continuously

Hello,

I have a problem with my laptop. It won't turn the display on at all its just blinking the caps lock light. I have cleaned it and change the thermal paste, I have tested in all the possible ways but nothing. If I take the ram off the light is going off but the laptop will restart. I took the hdd off and the ram as well and nothing, tried to swap the ram still nothing. Pressed the win+b, num lock + b, insert, F2 etc etc etc nothing.
I've wired up on my tv nothing. I have done everything I could whatever I found on the internet still nothing. reset bios, take the battery off, test the battery. My last solution if you haven't got one is to use a big hammer and smash it. LOL

I'm looking forward to hearing from you. Please send me an email on ***@*** if you have something for me.

Thank you guys

Cheers
Cris
