GPD Win, no/black internal display [is Hardware failure not software]:

My Win 4 died mid-game and hasn't shown anything on the screen since. I can connect a monitor and see it boot to gaming mode, and can access the terminal with Alt+Ctrl+F2/F4, but there's nothing but the backlight on the internal screen.

I've upgraded to latest, rebased to older versions in other posts, but I'm stuck.

Desktop mode the internal screen is the main, so can't do anything there, nor see mouse to try to use a monitor

Could you try booting a live iso and confirm it's not a hardware failure?

Aru•8/11/24, 11:30 AM

I'm on the 6800u win 4 and don't have this issue

LeftyPencilOP•8/11/24, 11:41 AM

yeah I cant see the BIOS
Pressed Fn+F7 on boot, zilch
Guess I have a shiny brick?

Aru•8/11/24, 11:42 AM

Could you not hook it up to an external monitor?

LeftyPencilOP•8/11/24, 11:43 AM

I am, still not seeing it

Aru•8/11/24, 11:43 AM

My immediate first reaction would be that it might be a hardware failure, since you can't even see the bios menu

Aru•8/11/24, 11:44 AM

If it was a bad SSD, you'd still be able to see the bios menu

CheZZ•8/11/24, 11:53 AM

my professional opinion is that the screen is toast

CheZZ•8/11/24, 11:53 AM

given that you see nothing on it

LeftyPencilOP•8/11/24, 11:58 AM

Alright, thanks I'll check out replacement screens

CCheZZ given that you see nothing on it

Aru•8/11/24, 12:03 PM

What's weird is that I'd expect video out to work

Aru•8/11/24, 12:04 PM

But yeah, some sort of hardware issue would be my guess

LeftyPencilOP•8/11/24, 12:10 PM

I'd like to at least remove and reseat it first-does it need to 100% discharged?

Aru•8/11/24, 12:19 PM

No idea on that, but if you want to 100% discharge, could you disconnect the battery + hold power to remove any residual charge?

CheZZ•8/11/24, 12:24 PM

mobo fried? you said that backlight worked?

CheZZ•8/11/24, 12:26 PM

i don’t know nearly enough about the GPD Win machines to tell you with certainty, but it does sound like some sort of hardware issue

Aru•8/11/24, 12:28 PM

Tbh I don't know either, maybe someone in the gpd discord or subreddit might have more info

LeftyPencilOP•8/11/24, 12:37 PM

Swapped a screen with another unit that at least shows the GPD logo, same behavior-just backlight works

Gonna swap back to ensure the screen still good but dang

LeftyPencilOP•8/11/24, 12:39 PM

Both screen still good

LeftyPencilOP•8/11/24, 12:39 PM

Imma close this, but thanks for helping be find it's hardware

LeftyPencilOP•8/11/24, 12:49 PM

Mine tend to turn back on if power is held. Guess that's not normal?

Aru•8/11/24, 1:18 PM

how can it turn back on with a disconnected battery?

LeftyPencilOP•8/11/24, 1:36 PM

Oof I terribly misread

LeftyPencilOP•8/11/24, 5:36 PM

Just for completion, a video of what's not happening-blue unit.

Black unit has other issue from being off for a long time, but at least can access BIOS

GPD Win 4 no internal display

Swapping screen didn't fix

Aru•8/11/24, 6:44 PM

woah, there's a blue version? that's nice

Aru•8/11/24, 6:45 PM

but yeah, that definitely doesn't look promising

AAru woah, there's a blue version? that's nice

LeftyPencilOP•8/11/24, 7:23 PM

Lol just a skin

LeftyPencilOP•8/12/24, 8:21 PM

I was advised to reset the BIOS by pressing the reset by the B button or go nuclear and factory reset

I'll backup saves and mods before either after work

Aru•8/12/24, 8:51 PM

oh yeah, there is a bios reset via the little pinhole on the side. not sure if it'll help, but doesn't hurt to try

LeftyPencilOP•8/13/24, 11:40 PM

No luck, gonna backup my saves and try the reset, but if the reset screen can't appear on a monitor, I'm just gonna live with a non-portable device.

Aru•8/13/24, 11:41 PM

rip hardware failure

LeftyPencilOP•8/13/24, 11:44 PM

I got greedy, it was 4tb and "surely I'll sell the other one" :dispair:

Aru•8/13/24, 11:45 PM

well you have spare parts now?

LeftyPencilOP•8/13/24, 11:46 PM

Would reseating the ssd be worth a shot, or just continue with a reset?

Aru•8/13/24, 11:47 PM

no idea tbh. i highly doubt it's the ssd, I was just trying to think of every possibility

LeftyPencilOP•8/14/24, 1:15 AM

Welp, the reset/recovery screen doesn't show on a monitor. I'm now afraid to guess where the buttons are, as I cant see the BIOS screen.

But, it's for parts now..so might as well do both and pray I don't fat finger it. Guess I'll learn how to swap the ssd after all

LeftyPencilOP•8/14/24, 1:17 AM

I'll record for the next gal

LeftyPencilOP•8/14/24, 3:18 AM

Blue never entered recovery mode, RIP

Swapped the ssd and seems ok, but I'll definetly check how to get an earlier battery warning to avoid this!

LeftyPencilOP•8/16/24, 3:05 PM

I forgot that I wiped the recovery when I installed Bazzite as I lost patience trying to dual boot

So there was no GPD recovery to access in the first place! ><

But learned plenty lol
