Hello Everyone,

Long story short, I got this unit for very cheap.
I've started to experiment with it's BIOS, as I did before successfully with an M900. However my very bad quality SOIC clip broken while dumping of the biosof and it must have damaged something on the panel, because it does not turn on, and does exactly nothing when powered. The maximum voltage that could have affected something is the 3.3 or 5v from the IC clip, because the unit was not powered while the bios dumping was in progress.

I've performed some measurements:
- 20V rail perfectly...

Re: Lenovo Thinkcentre tiny M90Q gen 1 - no 12V rail

+SIO_SB3V should be present at the EC (if +3V3_DSW and +3V3_S5 are indeed present). The rest of the supplies are switched on by PS_ON# from the EC after power button is pressed (ONOFF# from SW1, should be pulled high and go low when pressed). Refer to your power sequence on pg 60 to help troubleshoot. You won't get any 12V till you have PS_ON# from the EC.
