So i must order a new PU5401 to replace it and test it again, correct? -
On T470s is on J5 (hidden behind the Mac Address sticker) in case anyone is searching for it

Still dead with fully charged battery. The problem must be somewhere else. Any ideas?Leave a comment:

Since i must order it and wait 3 weeks for delivery is there any other measurement to take to verify it's faulty?
Also if the charger ic is faulty the motherboard should power up if i connect a charged battery, correct?Last edited by Andreasbest; 07-28-2025, 01:26 PM.Leave a comment:

Thank you for replying. To make sure i understand, you want to measure all these voltages and check ground resistance on PR5401 ?...Leave a comment:

I have no 3v. I think i get no voltage from PU5401 but not sure, i'm totally dumb in reading schematics.
If someone is willing to help i'm on the bench now and for the next hours. Thank you!Last edited by Andreasbest; 07-14-2025, 02:12 AM.Leave a comment:

Lenovo Legion 5 Pro 16ACH6H Water Damage
Hello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!
