Won’t Turn On e kxts is turned on, the maintenance light of ASUS is on

ASUS k53s laptop boot indicator light is on,Won’t Turn On, found that the arrow points to two MOSFET, no conduction is controlled by a small six pin chip behind, can not find the same replacement, directly remove short-circuit 34 pin, the current immediately surged up,Normally booting up.

[maintenance process]

Received an ASUS k53s notebook, can turn on the indicator light, the current is only 0.1.After standby 0.02 switch, the current is only 0.1, 3.3V and 5V memory power is normal. Without CPU graphics card,VCC,CLK reset is normal, BIOS is also brushed, and the well-known resistors are soldered once, which has no effect.

Finally, it is found that the arrow points to two MOSFET, and no conduction is controlled by a small six pin chip.

And can not find the same replacement, directly remove short-circuit 34 pin, the current immediately sped up,Normally booting up.Although the boot can run normally, but the shutdown indicator light is still on, directly control the other MOSFET signal to the root line.

After all, it’s an old machine. It sticks to the principle of being able to use it. It’s barely repaired.
