White screen means the display doesn't get power. Did you make sure it's not a cable or panel issue first?OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).

If anyone knows how to force the external monitor as primary for Notebooks of those models11-02-2024, 09:18 AM -
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... -

After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
