[Badcop79]

Hello,
I need help.. My Asus P2520 (motherboard P552LA-LJ) won't power on. After plugin charger, PD8103 and the on the other side PU8101 are very hot.
I check some point on repair guide and:
"17 PSL8103 +12VSUS 1483" I have 0V
"3.PSL8100 +3VAO 460" I have 3V
"7. PSL8102 +3VADSW_ON 567" 0V
"2.PSL8101 +5VAO 503" 0V

Can anyone help me?

Thank you

P.s. sorry for my english....

5VAO is an always on voltage. Remove all power and post resistance to ground measurements for PSL8101 .Do you have a boardview, and do you have a DC lab power supply
