Tyvm!

Turns out there was a short on CPU rail. The CPU is most likely fried. Sent it in to Acer. Lets see what they say.

So it seems 😬 Whats wrong with yours?...

This is the backside, i did look there before but around the power jack. Seems to be something on the upper side. Ill unscrew it later to check.

But. I think I found some shorts 😬 it might just be grounded Components and everything is as it should be, but worth checking with you before proceeding.

I attached another picture of the overview, and all blue spots are 0 ohms to GND.

There is a capacitor close to the Battery Connector that could be faulty since it shows 0 ohms on both sides. Marked in Purple. Then again, if the rail is shorted some other way...

Ok. Lets be methodical

This is the full board, and Ive numbered each Component that could be an IC and ill try to identify them.

1: RT3674AE, CPU power IC, not what we are looking for.
2: ndc300ra, MOSFET drivers
3: USB IC
4: USB IC
5: USB IC
6: "P08 Q03S FPL0288", could not identify, but doesnt have the pins expected from an IC, and is not located where expected.
7: W25Q16, 16bit Flash memory
8: NCP45495, 26 V, 4‐Channel Voltage Bus and 4‐Channel High‐Side
Current Shunt Monitor
9: "Z51A 5334"...

These are both un the upper side of the mb closer to the Battery. One is a 4 channel voltage bus and 4 channel high side current monitor, the other i havent found any data on. Could that be a rare power IC? Ill try some more googling.

No BQ Component found. But now I know roughly the size and number of pins....

I have a nitro v16 that died. Need the schematics to continue fault searching. I would very much appreciate help finding them or similar mb schematics!

I believe the mb number is DAOZPUPIAE0 REV:E

Double checked and you were ofc right about the CPU IC. I just cant identify the correct one.

Will request schematic.

Hmmm. Ive been digging through my full MB now and I really feel that the last one i posted should be it.

I've found ICs for the USB. 3 of them. I've identifies multipin mosfets, 4channel bus monitor, additional mosfets and some smaller multipin Components i could not identify. And the big ITE on the backside of the MB. But nothing that resembles a power IC.

Im calling it a night for now....

Ah, ok then! 😅 I did find a schematic and the actual pin that powers it. Thank you for redirecting me back. How big a Component am i looking for? Similar amount of pins?

Ok. Got time to sit down again. What I thought was the Charger IC was a USB IC, so that didnt really help.

But. I believe I found the Charger IC now. Top side says: RT3674AE GQW AG2YA. Richtek PWM controller (for AMD?). It seems to be unpowered as I cannot get any voltage to ground on the components tied to any of its pins. I attached a picture of my measurements.
Red area: no voltage to GND at any point. Measured outside of this area as well without luck.
Green area: 3.35V to GND (left pin 3.35V, right pin 3.32V)
Blue area: 0V to GND
Purple pins:
1:...

Thank you very much for the added Directions. Ill report back tomorrow with further findings.

Yes! Papaya salad is awesome! We live on Koh Lanta south of Krabi town. Relocated here from Sweden semi temporarily and so far it has been a GREAT decision! The whole family loves it. The only downside the Odd power spike to muck up my hardware 😅

Dang, 3.05V so Battery seems ok. The search continues.

I did try to disconnect it to hard reset, but never measured it. Thank you very much for the suggestions. Will report back!

I've hade this computer roughly a year. Last months it started behaving irregularly. Powering off mid stride when on Battery, requiring power to be plugged in to boot even though Battery shows full when booted again, refused charging and power on at some point which I managed to get past by holding the power button pressed long among other things. I've never dropped it, and no liquids. As far as im concerned its in very good condition.

A few days ago, i powered it off, and 30 minutes later it was simply dead. No reaction on diodes on Brick Charger or usb Charger. Tried holding power...
