emachines d525

[juandres666]

Hi all,
I have an emachines d525 with no power. The power connector is ok, I tested and it gives 18Vcc. The batery is nor charging. All LEDS are off while the power cord is connected.
I have attached the schematic.
Thank you for your help.
Best regards,

Juan A.

Check resistance to ground (all power remnoved) and voltage at R9. If everything seems fine, check the DCIN-Mosfets (U2 &U3) in Ohms Mode between D-S-G with all power removed.
