I’m having a critical issue with my Razer laptop (Razer Pro, around 2019 model). Earlier today, I went into the Synapse app under the Performance tab and switched to dedicated GPU mode to increase GPU power. The laptop immediately restarted, but now the screen stays completely black on boot.
Here’s what’s happening and what I’ve tried so far:
-
The keyboard lights up, and I can hear the Windows startup chime and fans, so the system seems to boot normally.
-
The display stays black, and I can’t see BIOS or the Razer logo.
-
I’ve tried connecting to external monitors via HDMI and USB-C, closing the lid, and pressing Windows + P to switch display modes — no signal appears.
-
I also tried the following reset steps:
-
Full power drain (unplugging, holding power button for 30–60 seconds).
-
Ctrl + Alt + Del + Power reset combination.
-
Repeatedly pressing F1/F2/F9/Del on startup to enter BIOS (no display).
-
-
The power cord and battery appear to work fine.
It seems like switching to dedicated GPU mode caused a firmware or GPU configuration crash, and now there’s no video output at all even though Windows is running in the background.
I’m in the middle of a critical project for work and really need help recovering this system quickly. Can you please advise on how to reset the GPU mode or reflash the BIOS/EC firmware to restore the display?
