[B]People, thank you so much for your help! Everything is working now![/B]

I ended up resoldering the original [B]BQ24780[/B] back in because I noticed that the new one wasn't soldered properly, and the original was actually fine.

I really regret not spotting that [B]faulty capacitor[/B] earlier. I did so much unnecessary work... but I guess I can blame it on my [B]lack of experience[/B] 😅.

I found this spreadsheet on the forum. Well, this is normal resistance, right?

Okay, you're right, I'll wait and try to find something. I'm waiting for someone's help. Thanks in advance ❤

small update. I cleaned the board again and saw that the capacitor near the mosfets of the video chip was damaged. I unsoldered it, now there are kiloohms on the shunt. But the nvdd resistance (inductors) is still the same low 0,3.

Could you tell me what to do next?...

Yes, it shows exactly 10mA.
Very interesting... A bit more information, in case it's important:
This laptop has never been damaged by water, but at the same time, when I disassembled it, I found that it had never been serviced since purchase... There was a lot of dust and dried-out thermal paste.

All inductors have correct resistance. The battery was completely discharged to zero. The laptop just suddenly turned off and that's it. If you have any ideas, I'd be happy to hear them.

For now, I'll try to figure out the low resistance on the shunt…...

Hello everyone, I have an [B]ASUS FX506LI[/B] laptop that does not turn on, and I need help diagnosing the issue. Here is what I have checked so far:

Hello. I'm completely new to repairs. I've only had the opportunity to repair iPhones and various simple devices. But now I'm getting into it. I want to be knowledgeable about this. My first complex repair was a sapphire nitro rx 470 4gb video card. After that I took up repairing other equipment... wish me luck <3
