MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

Seems like we are dealing with a case of a corrupted BIOS after Intel Driver software attempted to flash the bios (haven't seen that before).

Under the thermal cam, I can see that the CPU is initiating a heat signature for a second... -
I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue.... -
Hi all, I am working on Hp 15-ca2003ca (MB DAG7BDMB8F0 REV:F). The problem was totally dead. Upon diagnostics, there was a burnt SY8286BRAC. I replaced it with another one.

But when I press ON/OFF button, I see the power LED glows for a sec & then shuts off. Same happens when I press the ON/OFF button over again. I just put the Meter leads on the 3.3/5V coils & the meter shows that these both volts are generated & then in a sec. goes away. I re-programmed the...
