Hello guys. I got this motherboard that had liquid damage. The motherboard's type-c controller IC got shorted which resulted in main power rail failing to be produced and after replacement of the IC the main power rail returned. But the board is turning on and off. The current consumption is around 0.120Amps@20volts. After like 10 seconds it turns off and on endlessly. Checking the voltages on the coils:
pl701-9.04 volts
plpl101-5.1 volts
pl201-1.2 volts
LT1-0(0.685kohms)
pl301-1.05 volts
pl100-3.3 volts
pl614-1.04 volts
pl402-0.9 volts
pl613-0...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Macbook Pro 820-4924 Not powering on
Hello, I got a macbook pro motherboard 820-4924 that refuses to turn on. The motherboard draws 0.22 amps on bench PSU and PPBUS_G3H is 12.59 volts. P3v3s5 and P5v1_sw are both present and power button has 3.3v but it does nothing. The charger light blinks between green and orange. No visible damage on motherboard aside from lint and dust. The charger was swapped and there was no difference. What could be the issue here?...

Boots very slow and sometimes gets stuck on bios. I think it needs ME cleaning. Help appreciated....

Optiplex 7090 Tower no image
I think it needs new bios region and possibly a clean me region. Service tag 3R15KH3...

Re: No Power DAZAARMB6E0 REV E
This problem seems to be quite common. It seems to be a simple charger issue. Connect a decent acer charger and 19v will come on.

Re: Lenovo v15 g2 Flashing power LED
The BIOS you provided didn't POST and it's showing strange symptoms. The laptop's white power LED flashes like before with battery disconnected. When I connect the battery, the LED doesn't flash it just stays on. Nothing gets hot on the board when in this state. I'm really confused whether this is a hardware fault or a software fault....

Re: Lenovo v15 g2 Flashing power LED
The provided BIOS wasn’t able to POST so it must be a hardware problem. Thank you for your effort hardware1....

Lenovo v15 g2 Flashing power LED
board number HV460 HV560 NM D474 Rev2.0
The laptop had a windows update and it didn't turn on since then. The power LED flashes endlessly. So I'm hoping it's a BIOS issue...

Macbook air a1369 emc2469 boot issues
Got a macbook air that fails to boot from any drive be it external or internal. It just shuts down when the progress bar is about 25%. After it's off i can turn it on normally with the power button. I tried flashing a clean ME efi but there wasnt any difference. What could be the issue here? I can take measurements on the board if needed. There is a bit of liquid damage on the back of the board. I uploaded it to the drive folder. And also here's the video footage. [URL="https://drive.google.com/drive/folders/1hxA1W2-zGOL99TY47dDzIb6YHjc9RMvh"]https://drive.google.com/drive/folders/1...
