If the HDMI cable is disconnected before the shutdown, the laptop powers off completely and correctly. Important note: Once the system enters this "stuck" state (black screen, power LED on), unplugging the HDMI cable does not recover the system or allow it to finish powering off. It remains completely frozen. The HDMI cable must be unplugged before initiating the shutdown sequence to avoid the hang. Additional troubleshooting: I have also tested this with two different HDMI cables to rule out a faulty cable, but the issue persists regardless of the cable used. Regression Details: This is a regression introduced in kernel 7.0.0-28. I have tested previous kernels on the exact same hardware and they work perfectly (the system powers off completely even with the HDMI connected). Fails in: Kernel 7.0.0-28-generic Works in: Kernel 7.0.0-14-generic, 6.x branch Steps to Reproduce: 1. Boot the laptop with kernel 7.0.0-28. 2, Connect an external monitor via the HDMI port. 3. Shut down the system from the GUI (or via sudo shutdown now). 4. Notice the OS halts, but the laptop's power LED remains on and the machine does not fully power down. 5. Unplugging the HDMI cable at this frozen stage does nothing; the machine remains stuck and must be forced off by holding the physical power button.
