    00165 Full Fan No Boot (Cold CPU)

    Sorry, I must've had a long day that day. R8162 is no stuff... Not 8167, 8167 is indeed there. I removed R8168, R8164, R8165, and R8166, one by one and ALL_SYS_PWRGD Did not change.

    00165 Full Fan No Boot (Cold CPU)

    Have a 00165 that goes to full fan immediately upon plug-in (regardless of TP). Checked all rails are present except no VCORE. Noted some solder balls around C1031, but other than that the board looks absolutely fine. All 3.3 V present, all 5V present, all 1.8V present (except VCORE), all 1.2V...

    Late 13 3662 no bklt

    I will check. My other question is, is there a way to reliably test a screen backlight without getting a new one? I am out of known good, am at a down point in cash flow so can?t buy a known good and cant afford to take the hit of buying a new one if it?s indeed not the problem.
