This clevo came with a pch in short and a PQ25 very hot (this mosfet is ok and I have 3.5 Ohm PL10 VCORE ??? see pag. 97), after removed it I'm waiting to order a new one because I'd want to check for other issue.
1) No VDD5 , caused by missing signal DD_ON, reading the power sequence pag. 112 this signal should be present, it is generated by U26 pag. 93 (P2808 http://www.datasheetcafe.com/p2808-d...controller-ic/) , on it I read:
1-19V 2-19V 3-19V 4-0V 5-0V 6-3.3V 7-0V (DD_ON) 8-19V
if I remove Q49 (A-B) I exclude DD_ON and VDD5 increases to 5V.
2) 3.5 Ohm on VCORE is too low ?
thanks
