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...

I've uploaded the schematic and the boardview for this unit, because it was not available before....

Hi,

I want to repair a Lenovo M90q which currently does not turn on, made some measurements, but unfortunately I was unable to discover the issue.
