Power-on fault is no power on, and there is no current in standby. I thought it would be good to turn off the power, and the battery was turned off. As a result, 1A or so was powered on again and died.
When the motherboard veneer is removed, it can be powered on for standby 0 but switch, and there is none of 3V and 5V in standby. This computer is produced after switch. After switch, 3V can come out, 5V can’t come out, 5V is turned on or not, and the current is 0.003.

Only refer to the drawing, brushing BIOS is fruitless.

Running time sequence, it is found that there is no standby condition below 3P3. According to the time sequence, there is neither DPWROK nor SLPSUS. This one is sent to the bridge, and there is one after EC’s standby VCC switch. DPWROK and RSM RSMRST are connected together.

Tried to turn on 5V and generate 3V VA, now everything except DSWPWROK and RSMRST# is available, and the current of switch is a little higher.

Suddenly, it occurred to me that after the battery was buckled at the beginning, it could be powered up to 1A, and all the accessories were put back, and it was still 1A when the battery was turned on again. I downloaded one memory, but actually current of change booting up. It turned out that only static electricity plus one memory was broken.

Remove the battery,switch becomes 0.003, install the battery, and switch starts normally. Before, all the contacts were without batteries, which might not be common. This has changed, and it’s amazing.
