Hi. I decided to apply new thermal paste to an old W530 I bought. It's not my first time doing it so I felt decently confident. The application itself went well, but now the laptop cannot boot - the power led blinks for one second and then nothing happens, fans don't even turn on.

I think I either statically shocked the cpu or did physical damage to the gpu. I did NOT however touch the cpu directly, but looking back I was wearing a fleece shirt (great idea, haha), and obviously I touched the heat sink etc - so could the shock have been conducted to the cpu?

I noticed a lot of old paste on the small power pins (?) around the gpu shiny processor square and spent some time trying to remove the paste, maybe I damaged the gpu in the process?

My question is: can I know whether the gpu or cpu is dead? I'm thinking that the laptop should be able to boot without the gpu if the cpu is alive?

Thanks
