I returned home from college. My MacBook battery was flat. Plugged it in. Nothing. Won’t boot. Waited for an hour. Nothing.
When plugging the charger : 20v at 0.02 amps.
pressing any key will make the « low battery » icon show up. Then switch to 5v and 420mA constant. Trackpad clicks, keyboard works.
Decided to put the board into another M1 body with a charged battery, it’s booting perfect, still 5v and 420mA tho, and battery is not charging.
I diode moded every pin of U5200 and they’re all fine. I know very little about Apple silicon machines...

Hello
I need bios dump dell latitude 5420 PCB: LA - k491p. (cpu 11th)
every one please help me
thanks! -
Hi,
I have a Thinkpad P53 that boots but doesn't show anything on the display since selecting 'Discrete' in the Display options in the BIOS.
My intention was to flash the BIOS with a dump from another P53 but the good machine has a Winbond chip and the broken one a Gigadevice chip. Does anybody know if the dumps are interchangeable or, if not, does anyone have a Gigadevice dump I could use or maybe fix my dump? I'm afraid i don't have the serial number as the labels are missing and I cant get the BIOS info up on the screen.
Thanks, -
