ASUS Zenbook Pro 15 OLED UM535: Sleep Black Screen Fix
AMD Ryzen 9 6900HX • AMD Radeon RX 6600M • Windows 11
The ASUS Zenbook Pro 15 OLED UM535 is a powerful creator laptop combining the AMD Ryzen 9 6900HX and AMD Radeon RX 6600M discrete GPU. When the laptop wakes from sleep but shows only a black screen — no cursor, no display output, just black — the cause is almost always the AMD graphics driver not correctly reinitializing the OLED display after a power state transition.
Press Win + Ctrl + Shift + B to Reset Display
When the black screen appears after wake, press Win + Ctrl + Shift + B simultaneously. This Windows shortcut resets the graphics driver and reinitializes the display without a full reboot. In most cases, the screen will flash and return to normal within 3 seconds. This is the quickest recovery when the black screen occurs.
Update AMD Radeon Driver
Download the latest AMD Radeon driver from ASUS Support specifically for the Zenbook Pro 15 UM535. AMD and ASUS release driver updates that fix OLED display reinitialization after S3 and modern standby sleep states on the RX 6600M platform.
Switch from Modern Standby to S3 Sleep
Open Command Prompt as administrator. Run powercfg /a to check available sleep states. If Modern Standby (S0 Low Power Idle) is active and causing issues, run reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 and restart to force traditional S3 sleep on compatible AMD platforms.
Disable Panel Self Refresh
In AMD Software: Adrenalin Edition > Performance > Tuning, or via MyASUS > ProArt / OLED settings, disable Panel Self Refresh. PSR on OLED panels can cause wake-from-sleep black screens when the driver fails to properly exit the self-refresh state and resume normal display output.
Update BIOS
Check ASUS Support for BIOS updates for the UM535. BIOS updates include ACPI sleep state improvements for AMD Ryzen 6000 series laptops that fix OLED display reinitialization failures during wake events. Install while plugged in using MyASUS EZ Update.
Adjust Hybrid Sleep Setting
In Power Options > Change plan settings > Change advanced power settings > Sleep > disable Hybrid sleep. Hybrid sleep saves a hibernation file during sleep entry, which can conflict with the OLED display state on AMD systems during the combined wake sequence. Disabling it simplifies the wake path.
“My Zenbook Pro 15 OLED woke to a black screen about half the time. Using Win + Ctrl + Shift + B recovered it temporarily, but updating the AMD Radeon driver from ASUS Support fixed the root cause permanently.”

Why does the ASUS Zenbook Pro 15 OLED UM535 show a black screen after sleep?
The AMD Radeon RX 6600M or integrated GPU fails to reinitialize the OLED display correctly after a sleep wake event. Causes include Panel Self Refresh not exiting properly, Modern Standby incompatibility with the OLED panel power state, or an outdated AMD Radeon driver. Update the driver from ASUS Support and disable Panel Self Refresh.
Can I use Win + Ctrl + Shift + B to fix the black screen on the ASUS Zenbook Pro 15 OLED UM535?
Yes. This keyboard shortcut resets the Windows graphics subsystem and typically restores the display within 3 seconds without a reboot. It works on any black screen caused by a display driver hang or failed reinitialization. It is a reliable recovery method but does not address the root cause — update the AMD driver for a permanent fix.
Does the ASUS Zenbook Pro 15 OLED UM535 support S3 sleep?
On some configurations, yes. Run powercfg /a in Command Prompt to check available sleep states. If only S0 (Modern Standby) is listed, the registry override method can force S3 on the AMD Ryzen 6000 platform. S3 sleep is more reliable for OLED display reinitialization than Modern Standby on this generation.
What OLED display does the ASUS Zenbook Pro 15 OLED UM535 have?
The Zenbook Pro 15 OLED UM535 features a 15.6-inch Samsung AMOLED display at 2880×1620 resolution with 120 Hz refresh rate, DCI-P3 wide color gamut, and VESA DisplayHDR 600 True Black certification. The OLED panel provides exceptional contrast and color accuracy for creative professional work.
