Hello everyone!
I have an Acer Aspire A315-42 with an EH5LP LA-H801P motherboard. The power button on the keyboard is damaged. I have 3V on pin 1 of JKB1 (ON/OFFBTN#), but when I press the keyboard, it stays at 3V and doesn't drop to 0V for power-up.
If I manually jumper the power to ground, the laptop powers on without any problems.
I've configured the BIOS so that when I open the screen, the laptop turns on without pressing the power button, but that doesn't work either.
On the main board, I've checked the LID_SW# signal, and when the lid is closed, it's at 0V, and when it's open, it's 3.3V.
I've downloaded and applied a BIOS update, but everything remains the same.
