I forgot to include the magnet, thats when the voltage change when the LID is closed, it drops to 0.8 to 0.2 to 0v randomly.... -
See attached. Carefully measure the voltage to ground of LID_SW#.
Expecting this logic level to change when the LID is OPEN vs. CLOSED.

Thank you for your reply! I have measured the PIN 1 and 2 and read 3.3V on both when the LID is Closed and Open....Leave a comment:

Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
Good day!
I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.
Here are the voltage readings:- Input – 19V (stable)
- +LCDVDD – 3.3V briefly, then drops to 0V
- EDP_HPD – 3.3V briefly, then drops to 0V
- PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
- EC BKOFF# – 1.8V briefly, then drops to 0V
- PANEL_OD_EN – 0.3V
Is it possible that the EC chip is corrupted or damag...
