Hello all,
A Customer came with HP 4520s, Which has some strange things.
It restarts automatically when heating. okay, after restarts there's no display. The Keyboard's Caps Lock Light blinking. The Ram is good but because when i start the computer after an hour, there is no Caps Lock light blinking and display is fine but after a few moments the computers restarts automatically again and again Caps lock light blinking. I cleaned the fan, changed Processor Paste but nothing changed. Same problem. Anyone can help me.
Thanks

With Hp the most time is the Gpu, reflow the Nb and look what it does.

Yes these things cook GPUs like crazy. The heatsink is a piece of crap and could use improvements.
