Lenovo 110-15(LA-D562P) Laptop Does Not Turn On

 Laptop Model: Lenovo 110-15

Board number : LA-D562P

Symptom: Laptop Does Not Turn On

Maintenance Process:

There is a short circuit on the main board. There are traces of water ingress near the 5V chip.

Measure the 5V subsequent short circuit. It was found that PU601 was damaged, the chip silk screen was 5108, and the original chip could not be found in the drawing model G971ADJF. 

I have a few new Lenovo boards in my hand. Comparing the drawings with the AP7175 pin positions, I can just replace them.

Then power on and test the standby 5V, which is only 2.6V. After the test, there is no short circuit and the chip conditions are normal. This is because the chip is damaged due to water entering nearby. 

The chip silk screen is AWW6SF, the model SY8286C cannot find the original chip, and the material board has a similar chip. 

The comparison drawing is the same as the BAC6FB model SY8288C. After replacement, the standby 3V5V is generated normally.

Trigger the machine to turn on and the maintenance is completed.

Happy Repairing !!
