Thanks, only just got it back together - unfortunately no, same issue.
I suspect the issue might be with U2202 - would you have a fix for that one?...

Hello all, first timer, please don't shoot. Could I please have some help / any advice?

Laptop: Lenovo Thinkpad T14 Gen2 type 20W0
S/N: PF3B5BKX (on sticker with dash: PF-3B5BKX)
MB: HT4B0/HP4B0/HT5B1/HP5B1/HT4B2, NM-D352 Rev: 1.0

Symptoms: pressing power on, fan spins up but no POST, never getting to BIOS.
At first occurence battery drain solved the problem, but after I disabled fast startup in win11 it doesn't help anymore. CMOS battery has been replaced. Tried with built-in battery disconnected & on main charger, SSD removed etc, makes no difference....

Hello all, I am so glad I found this forum! I'm UK based, accountant by trade, out of 9-5 hobby laptop/pc fixer. First time in my life trying to fix something more complicated than a laptop screen replacement, which brought me to this place....
