Hi, I have a Lenovo Ideapad Z500 with motherboard VIWZ1_Z2 LA-9061P.
After pressing the power button, the power LED comes on for about 6 seconds and then shuts off.

+5VALW, +3VALW, +5V_PCH, +3V_PCH and are all ok.
I have missing +5VS, +3VS, +1.5VS and all the other main power rails due to the signal SUSP (generated by the EC KB9012QF-A3) stuck at GND.
The signals SLP_S3#, SLP_S4# and SLP_S5# (from PCH to EC) are all stuck at GND too while SLP_SUS# (from PCH to EC) is at +3V.
The signal RSMRST# (from EC to PCH) is at +2V.

Could comeone please...

I already tried multiple BIOS dumps from other website and the behavior is always the same.
I have tried plugging a monitor in the HDMI port but I get nothing on the screen.
I would really love to start checking the voltages but I don't have a schematic for this laptop. How can I do?


That's a 1-to-1 DisplayPort 1.2 repeater. If it is the problem, will the PC boot without it?...

I discovered that the Parade PS8330B chip gets very hot, too hot to the touch.
Could it be the culprit?

Hi,
I bought an Asus ROG GL502VS (that was supposed to be) with bricked BIOS.
