Compal LA-9411P boot issues
I have a motherboard from a Dell E6540 laptop here (with CPU and memory), when I connect a original Dell PSU (tested with a couple), the powerled from the power button is on (without pushing the button) and motherboard starts directly but the laptop does not start any further. The fan is spinning a few seconds, turns off in a second and within a second it spinning again. The led from the power button is off for the split second.
When I use the battery only, I need to push the power button and the same is happening as with the AC adapter.
With the battery or AC adapter, the laptop does not react on pushing the power button (laptop should turn off).
When I press the power button, the voltage drops to 0V and when I release the button it's 2.8V again.
The following voltages are there:
5V on USB
1.35 on the memory
2,80V on the power button, when I press the button it's 0V
U52 and U53 I have 3.30V
U46 ECE5048-LZY I have 3.30V
U51 MEC5075-LZY I have 3.30V
Any idea about this issue ?
