HP notebook CQ40 power failure repair after startup:
HP's CQ40 machine has been powered on and repaired several times, and I am preparing to replace the motherboard. When I disassembled the machine and powered it on, I found that the CPU voltage was missing. When I started the machine, I saw that the current was 0.26A. When I disassembled the machine and tested it, there was no CPU power supply. I tested the CPU power supply chip PU201 ISL6265. , 48 pin: VIN 19V 6 pin VR_ON: 3.3V 47 pin VCC: sometimes 1.1V, VCC comes from +5VS, that is the successor of 5V, find Q35 D pole has 5V, G pole 0V, measure Q17 2 pin 0V, Q17 1 3 feet failed to penetrate again. R152 pin 1 is 19V. Why is there no voltage in RUNON? Could it be that R152 is open circuit? The resistance is infinite when measured. Remove one from the material board and install it to start up the current.
