Hi, I was given this laptop by my uncle who said:- It would occasionally shutdown if not plugged in
- battery had been replaced
- touchbar would "strobe"
After fully charging the battery, with bluetooth disabled, no LAN cable and only wifi enabled, the laptop stayed on (screen on) for about 6-8 hours. Allowing screen to turn off while not in use, and it went for over a day.

When powered off, it would at some point have a... -
Looking for some advice on a 820-02016 board as I don't have much experience with these M1 machines. Learning the nuances of them as I go.
So the history of this machine was it had been in a bag where a bottle of water leaked. Presented as dead about a month ago, corrosion was mainly around the battery connector and it's sub-PCB. Some corrosion was noted on the board around UC300, CC325, CW1C7, CW1C8. That was it really.
Now without battery connected, USB-C will stay at 5V and cycle between 0 and 120ma. PPBUS_AON is cycling between 0 to 12.3V. If battery is connected,... -
I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery.

However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

Hello, i have a batch of 10 Macbook Pros A2179 bought from a Costco return wholesaler.
The 10 of them show the exact same behavior;
They auto power on, to internet recovery spinning globe, fans to 100%.
Power consumption on USB-C port is 0.43a, shuts down as soon as unplugged. Battery doesn't charge at all. However, it boots to 20V on the Ampmeter.
Based on their iBridge versions (4.x and 5.x) these were shelfed for a long time.
All of them power on the same way; 100% fans, shut down as soon as they are unplugged. Removing... -
Hi i have one Macbook Air 2020 where touch ID is not working (it's not scanning fingerprints). Touch ID was working before, there is no error message during scanning fingerprint it's just not scanning on screen you can see only fingerprint but there are no red updates as when it's working. Power button is working fine.
I've checked boardview and also schematics but i'm not able to find anything related to TouchID ... i have similar issue on a2338 where there was problem with PP3V0_TOUCHID and after replacing UT610 it was working but here i'm not able to find anything related to...
