Hi Ivan! I hope you were once again able to access your belongs in Irpin. I heard that the town has been recovered from Russian occupation - though many have went to meet with family elsewhere.

Anyways, I'm happy to report that my P14s did not need any of these fixes to work well with Fedora Linux 35. In fact, I would call it close to perfect! Everything just worked.

That said, I think you should probably keep this post! It has a lot of history behind the fixes and helps them appear higher on search engines. It also provides info for those on older BIOS versions. Many thanks for your help and continued discussion! :)

Thanks! You're right, let's keep it.
