I want to start by saying this was by no reason my fault. I was working on this laptop for a friend that stated his Laptop wouldn't come on. I checked the power, nothing. So I went to the cpu and found that liquid metal had seeped under the protective glue and into these caps. (I was streaming so I have video evidence for you non believers) When I removed the glue, the caps came out with it. Anyhow, what I need is a way to identify these missing caps. Please help a brother. The processor is a Ryzen 9 5900HX the motherboard is a G533 6050A3250201 REV 2...Today, 06:21 PM -
I have an HP 16 DAG3MMB3AAO REV A. The charge LED doesn't turn on.
So far, I've checked the three input MOSFETs, and all three seem to be in perfect condition. The charge IC is a BQ24781. The voltages I've checked are:
VCC: 19V
REGN: 6V
ACDET: 2.45
ACOK: 2.85
It's striking that I don't have voltages on the ACP, ACN, and CMSRC.
I'm a bit stuck on how this controller works and why it won't turn on.
