Hello everyone, I have a small problem.
On my desktop, I have an 820-00928 motherboard, with no image, no chime, no USB activity, and no external video.
The CPU and GPU heat up normally, and the battery charges at approximately 4 Amps. PPBUS_G3H 12.62 Volts.
Previously, it was damaged by a liquid spill, affecting the U3100 chip. An ultrasonic cleaning was performed, which turned out quite well. Some time later, the computer began to suddenly shut down, and the customer thought the battery was failing. The battery was replaced, and within a couple of months, the computer began to fail again, displaying the same error: sudden shutdowns, irregular startup, and the current failure.
The strange thing is that I installed a good, original battery. The computer turned on normally once, and after that, it didn't work again.
These are the values for the large coils.
L7410: 0.008 v
L7420: 0.008 v
L7211: 0.966 v
L7221: 0.966 v
L7231: 0.966 v
L7330: 0.933 v
LA640: 0.906 v
LA650: 0.906 v
LA350: 0.910 v
LA300: 1.354 v
L7030: 12.67 v
L8000: 1.014 v
L7960: 0.974 v
L7900: 1.205 v
L7660: 3.315 v
L7600: 5.13 v
L8410: 0.020 v down
LB700: 0v
Please could you guide me or enlighten me, thank you very much.
