Computer in question : Razer Blade 15 2020 Base Model
Model# RZ09-03286E22
BIOS CHIP: WINBOND W25Q128BV
What I'm trying to accomplish:
I want the computer to properly boot with an external display with the attached display disconnected from the motherboard. I have a CH341A programmer and full capability of modifying the BIOS easily. I Have tried various setting changes to no Avail.
What I've tried thus far: Too much to note and I really dont remember everything I changed but here it goes.
W/Stock BIOS - 1.06:
Disconnect the eDP cable from motherboard- no dice, no signal to external display
Through testing I found if the attached display is connected but cable is removed after POST the external monitor keeps signal.
Customizing BIOS attempts:
Primarily made changes under Setup > Chipset > System Agent Configuration > Graphics Configuration
I have tried various combinations of changing "Primary Display" (both of them, there are 2) to PCI, PEG, AUTO, etc.
Disabling Integrated graphics
then under > LCD
Changing active LFP to - No eDP
Primary / Secondary boot Display to EFP
Under Setup > Boot > CSM
Disabled secure boot
Under CSM changed "Video" to Legacy
Ive tried all at once, various combinations of each and nothin. May be some other options I attempted but just cant remember, anything that seemed relevant to boot displays, primary displays, etc.
Side note: During testing sometimes windows would boot and Id hear the welcome jingle, other times the laptop was stuck in a boot loop on its own. But never an external display signal. I did disable the integrated graphics driver in windows before testing just in case that made a difference.
Has anyone had luck on getting these laptops to work without the attached screen being connected or any ideas? I've wasted a whole day messing with the thing (not wasted when you're having fun right?) and dont want to give up on this task.
Reason I to want to do this:
Computer has serious heat dissipation problems I believe heatsink related, want to build a custom case and may do some water cooling just for fun. Also the battery is just beginning to becoming a spicy pillow (to no surprise if you read r/Razer) and plan to retire the unit as portable and just make it a desktop at this point.
TLDR;
No external display signal when the laptop attached screen is disconnected from the motherboard. Various BIOS changes were tried but all for naught. Any information is helpful!
