[Yoel Ren]

Hi, customer brought this in,said it died every few minutes.
i tried to turn it on, boots normally, and died after 15 minutes, after that, if turned on, only fan spin but no display.., is this repairable?
Visual inspection , everything looks good and pristine, any common issue ?

No schematic at all for these.
Do you get USB activity?
Check Caps Lock reaction too.
Don't you have another graphics card to try?

No usb activity at all, monitor hdmi channel doesnt recognize any hdmi plugged in, so looks like it doesnt even post..
No graphic card to test, because normal pcie gpu doesnt fit there right? Isnt’t it proprietary?

took off the whole logicboard, looks pristine, browse for good 30 minutes and doesnt got any information ..
