Re: No power ACER C5V01 LA-E891P

RB16 both sides 3V present?? If present, you can cut the track between diode and 3v_EN and thereby enabling 3V_EN from 3V_EN_R. Revived a dell 3567 15341 mb using this trick where the ram ic was not generating VTT but 1.2V was present on coil.

thanks for repllying sir but the owner has already claimed it.

If you have answered to me, so No. No Voltage on both Sides. I Had jumpered the Diode for Testing purpose and 3VALW/1VALW were Coming Out! But got a new issue, No pgood from the IC Coming Out. I decided to revert the Changes and ordered the IC. I Hope replacing will solve this...

Have you solved this when you bought the IC? Any updates?

If i remember correct, i had a cold solder joint at either RB16 or RB17. Either way, playing around in this area solved the issue for me.

To work with this board on a maintenance bench, we need to short-circuit the SWG1 switch first, only then can we continue analyzing the voltages.
