I have studio laptop without display but only showing flashing speaker volume hi and low. I try to put external monitor and did show the screen. After seeing the display on the external monitor, I did some hardware checking and the message flash in the screen saying "can not detect EDID EEPROM for the display monitor." Your post will be highly appreciated. Thanks...

Re: DELL Laptop Studio 1535 no display
Extended display identification data (EDID) is a data structure provided by a computer display to describe its capabilities to a graphics card. It is what enables a modern personal computer to know what kind of monitor is connected. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID includes manufacturer name, product type, phosphor or filter type, timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.
I believe your problem has to do with the lcd panel firmware and there is not much you can do . Try another screen and see if it appears again.

LCDVDD/backlight power are powered down when this happen, PANEL_BKEN_EC and ENVDD_PCH are also down to 0v. It's weird, it almost feels like the motherboard is shutting down the display...06-26-2025, 01:44 PM -

Hi, I have a Dell XPS 9500 which works when it want. Specs : I7 10750H, GTX 1650Ti 4GB, 15.6" 1920x1200.
It can works fine for hours until the screen goes black or the image is fully frozen (laptop unresponsive) or the display is glitched.
Then another issue is sometime the laptop doesn't wanna boot or post at all, after a "clear cmos" (disconnecting main battery and pressing power button for some time) when I'm pressing the power button the keyboard lit up but sometime the laptop display the Dell logo, sometime the screen can just lit black, sometime it launch... -
