Lenovo Thinkpad 330s not powering on.

GordosTacoShop · September 28, 2020

Lenovo 330s with ryzen 5 2500u. Won't power on, and is not charging. Charging indicator light not on.

Tested the charger and it's correctly reading 20~v, so I think I can rule that out.

I did all the typical troubleshooting.

Lenovo button does nothing.

Remove battery and cmos then power drain does nothing.

Removed one at a time- ram, wifi card, ssd, peripheral, speakers, display. Nothing.

I have a multimeter, but admittedly going in this deep is out of my wheelhouse. From what I can tell, there's a short somewhere (please correct me if I'm wrong, I'm learning.) Also, these two mosfets that are pictured are hot when it's connected to power. Does that mean anything to anyone?

If there's any other info I can provide, let me know. Thanks in advance.
