Re: ASUS zenbook13 unlock?

Thank you, will try it tonight and update accordingly.

Quick question: does EC has anything to do with encryption/lock (bitlocker as seem to be the case here)?

Re: Lenovo ThinkPad W520 Dead, shorted

Remove CPU (ideally also L96) and use post #4 to find out which driver is faulty. Once found, remove it, insert CPU and check if short is still present. Do not apply power.

That way you can check...

Re: Lenovo ThinkPad W520 Dead, shorted

Just to make sure I understand correctly. The short is on the 5V rail or is it also on the main (19V) rail? What is resistance to ground when you measure sense resistor after 2nd input mosfet?

It could also be a dead/shorted CPU depending on which FET in the driver chip failed(high or low side).

You can check but first remove the inductor (L96 in your case);
To check low side mosfet,...

Where are you measuring? Black on ground and red is connected where? If you are measuring L3051 to ground then 10ohm is normal. The low resistance is due to the GPU.

When you said "Applied power"...
