Hi, everyone.
I have this notebook that won't charge.
In Windows, the charger icon doesn't appear on the battery, but the charger turns on the notebook normally.
PU301:
Pin 5 (ACOK) - 5.97v
Pin 6 (ACDET) - 1.83v (should have 2.6)
Pin 16 (REGN) - 6v
PQ308 has no gate voltage, so it doesn't drive PQ309 low
With the battery connected, its voltage goes the reverse way to the jack, having 14v and not 20v:
PQ301 e PQ302
Pinos 1,2,3 14v
Pino 4 5v
Pinos 5,6,7,8 com 14v...

by StachujonesHello i have a problem with a ThinkPad X280 with NM-B521 Motherboard, laptop doesnt power on
I dissasembled IT and started Basic trouble shooting
+20v is getting to board so power delivery circuit is working
Next i started looking on the board and i felt a burning hot chip its BD4179 "ThinkEngine"
I desoldered it, no more chips are getting hot
But i founded that on the capacitor marked on the picture there is 0.8 ohm short to ground and it's not capacitor, after desoldering it it's Still 0.8 short
Could anybody help me with fixing this laptop... -
