Asus GL705GE motherboard FX505GD

Hi,
Asus GL705BE same GL505BE
Battery led always on
No 3VS 3V 5VS 5V

3VS and 3V POWER S. missing (both) ON signal <- PM_SUSB# = 0V Vin OK
On 5VS and 5V POWER S. missing both on signal Vin OK (5V) but (5VS)Vout is 3.2V ???

Believe the attached datasheet is common to the referenced SN10548 device.

Respectively, if ON1 / ON2 pins are logic low then the Vin should not be passing through to Vout.

Power down, meter in resistance mode (200 ohms). Check the resistance to ground of these rails and every coil on the logic board. Searching for very low resistance readings.

Can you post the full schematic here please - https://www.badcaps.net/forum/showthread.php?t=93751

No short
I'm focused on the 3.3 V on the +5VS out, I'have removed both power switch and this voltage is still present
If I remove the led board this voltage drops around 0.03 V ??
But if I connect 3VS power switch both 3V and 5V alw (EN1 and EN2 are 3.2v) disappears , strange behaviour

U9101 and U9102 are the same part,swap them around to check if theres a problem with U9101

LIDSW checked?? Is it located on the powerbutton board??
