A1297 820-2390-A no power

[hgoncalves]

Hi,

I have an A1297 820-2390-A that has no power. It has green light, but no fan spin.

I have 0V on PP5V_S3, and on U7201 I have 0V on P5VS3_EN

Diode reading on P5VS3_EN = 0.498

PM_SLP_S4_L has 0V and Diode reading on PM_SLP_S4_L = 0.500

Can you help?

This board only turns on pressing power button.

Did you check L7770 voltage?
You must change C7771 anyway...

You're right. It was the power button...
