Created attachment 131359 [details]
Dmesg for my ThinkPad E550.

SUMMARY


STEPS TO REPRODUCE
1. Download iso.
2. "Burn" to USB stick.
3. Boot.

OBSERVED RESULT
USB stick boots to blank screen. LED on USB stick (if present) blinks repeatedly, but nothing else happens.

EXPECTED RESULT
Boot to KDE desktop

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: KDE Neon 5.19.4
(available in About System)
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.73.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION

I have attempted to "burn" the USB key using Rosa Writer (as provided by the KDE Neon website), "dd" and "ddrescue", and booting with both UEFI with BIOS disabled, and UEFI with BIOS and CSM enabled, with the same result. I have seen reports that BIOS booting works but I am dual booting Neon with Manjaro, which is already installed using UEFI, so BIOS booting is not an option. The laptop is a Lenovo ThinkPad E550 (dmesg attached)

Does the Ubuntu 20.04.1 LTS ISO image boot?

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
