The notebook is not turned on, and you see a broken line after running, but you have to remove the capacitor to make it up. Direct flying line, power-on test, perfect lighting machine.
Asus X540UP notebook can't be turned on, the BIOS hasn't been moved, the CPU voltage is normal, turn on the bitmap, look for the small 6-pin conversion tube PU8804, disassemble it directly, and then connect it directly from the resistance of R0633 at the back of the CPU, then power it on, and the current is 0.26-0.54-0.68-0.48-0.53-0.44-0.75.
Power-on detection standby is 3V 5V, and the point switch is not triggered. Upon inspection, it is found that 3VSUS_PWRGD is pulled low, and the high level of 1.0VSUS_PWRGD is required first, so that 3VSUS_PWRGD will not be pulled low. After running the line, it is found that there is a disconnection, but the capacitor must be removed to make up for it. Direct flying line, power-on test, perfect lighting machine.
