Hi to all.
Need help with this laptop DV5 Board DAQT6AMB8F0 REV:F
Found short on Mosfet PQ26 FDS4410A. Used the schematic I found on this forum and followed the short to ground from capacitor PC107 to coil PL12.
Lifted one side of PL12 and the short to ground on Mosfet PQ26 is gone.
Following the schematic next component is the capacitor PC161 which is short.
Removed the PC161 tested it and it is ok but the positive pad on the motherboard is short to ground without the capacitor welded on.
I have the following coil measurements with diode mode on:
Without power
PL7=0.524V
PL8=0.382V
PL9=0.448V
PL12=0.013V
With Power
PL7=0.502V
PL8=0.630V
PL9=0.517V
PL12=0.05V
The laptop does not power on. When I press the power button I get power led on but when I release the button it goes off.
I also have charger port led on.
