Windows Update Caused Intermittent Black Screen After Resuming from Modern Standby or Extended Idle

[Ginny_S]

I have never posted anything here before and am certainly not an advanced user. However, immediately after the Windows 11 update 25H2 was installed, I started getting a black screen that would not respond with mouse or keyboard motion. The problem seems to be directly related to the Windows 11 update (January 15, 2026). Since I do not have tech support nor do I know a great deal about operating systems, the only option was to ask ChatGPT for help. I may not know how to troubleshoot the problem, but I am very good at providing a detailed description of events that caused this problem. This is a summary of troubleshooting that I tried working with ChatGPT over about 3-4 hours.

System:
HP Laptop 15-ef1083od (42B65UA)
AMD Ryzen 7 5700U with integrated Radeon Graphics
Windows 11 25H2 (Build 26200.7623, KB5074109)
HP OEM AMD graphics driver 31.0.21914.8004

Issue:
Intermittent black screen after resuming from Modern Standby or extended idle. The system remains awake (keyboard, power LED, fans active) but the internal display does not reinitialize. Only a restart restores video output.

Triggers Identified:

1. Lid close → reopen (Modern Standby resume)
2. Extended idle with lid open → display powers off → resume fails
   Short display blanking recovers; longer idle does not.

Findings:

• Issue occurs on battery and AC
• S3 sleep is not available on this model (Modern Standby only)
• HP OEM AMD driver is correctly installed
• Fast Startup is disabled / unavailable
• PCIe Link State Power Management not exposed (integrated iGPU)
• Preventing display power-off avoids the issue

Conclusion:
This appears to be a Modern Standby + AMD iGPU display resume timing defect introduced or exposed by KB5074109 / Windows 11 25H2. Not hardware failure.

Request:
Engineering review of AMD display resume path for S0 idle on Ryzen 5000U HP platforms, and guidance on driver, firmware, or OS remediation. (End)

Please do not beat me up for using ChatGPT. I consider it a viable option for troubleshooting. Otherwise it is the Geek Squad or some unknown local business.

I will also try to file a ticket with Microsoft. For now, I will use the Win+L when I leave my desktop.

This is already a well-known global issue with Microsoft and their Windows 11. I do not recommend that system due to instability. Use Windows 10 LTSC or Linux.
