Thanks a lot!

Hello
I have been working on a dead MSI MS-16R4 laptop. It has a blown mosfet on the input side, but also the PU15 is shorting everything to ground. The IC is labeled as AKUK 234. Does anybody know what it exactly is? Im unable to find a schematic for this board :/...

I've tried another genuine 65W dell charger and guess what... it's working and the battery is charging. Well again thanks for the help and kinda sorry for wasting your time with my rookie mistake.

Im gonna borrow another charger just to be sure.

The value of PR4305 is 33R ohms. Neddle is present and straight. Also i've unplugged the charger connector and the voltage to ground on PIN 4 (white wire) is 0V on aftermarket 65w charger and 0.07V on original 45w charger

Genuine 45w charger shows 3.3V
Aftermarket 65w charger shows 2.3V

Hello everyone

I have been working on this laptop mentioned in the title, it initially had a blown PQ4410 mosfet. After I replaced it and repaired the damaged PCB the thing started working again, but there is still another problem. The laptop won't recognize genuine battery and charger. I have 3.3v KBC PIN36 PS_ID and this is pretty much where my knowledge ends.

Where should I go next? Replace the KBC or measure something else?...

Yup, installing an original used battery solved the issue. The laptop is charging now. I've spent more time on this than i would like to admit.

Anyways, many thanks for help!

Both mosfets measure in M ohms in any possible way.

I'm gonna go and read the whole thread while I wait for the "new" used battery.

What do you think about my measurements of the charger IC? I've tried to compare them with the datasheet, but honestly working on this laptop is something new for me. I usually deal with dead bios, dead DCin mosfets, or simple shorts that I can diagnose quite easily.

I don't know if the tool is compatible, I've only seen it being used in other threads. Any suggestions of what software should I use? Or can I provide any other infomation that can help?

edit:

I'm sorry, but how do I check the leakage? You mean the voltage drop? It's 0.274V between pin 1-3 and 2-3...

The second screenshot of batterymon with 96% charge is with the original ASUS battery that the laptop came with. But as I said there is 0V present on its terminals. (The cells are 4.03V)

Hello everyone

I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).

I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,...
