Thinkpad laptops thankfully have a BIOS option to revert the behaviour to normal, where F1-F12 perform their nominal functions. I'd probably pay an extra €50 for a laptop that didn't come with a stupid Fn button at all. Might want to throw some more money at a few more keyboard modifications: my bottom row is Fn CTRL Win Alt Space AltGr PrtSc Ctrl; that PrtSc button clearly has no business being there. Arrows & PgUp/PgDown are too small. Backspace is too short. Etc.
Yes, normally a BIOS setting on laptops I think. Before changing it I was hitting sleep constantly since they'd put it on F1, jammed up next to escape.
My Dell has it too, thank goodness.
You need Fn anyway because even 16" now come without a navigation block and even if you have it (asus tm420 though they ditched that too) you have no way to make PrtScr, Break, ScrollLock.
The real atrocity is placing it on the left side when 90% of the most used combos are on the right eg Fn+arrows for paging and home/end.
It could be way better if Fn was on the place of ContextMenu - Thinkpad already used it for the stupid PrtScr and now even more stupid Copilot key.
Thinkpad laptops thankfully have the option to switch Fn and Ctrl Key in the bios, because that Fn in the bottem left is reserved by my muscle memory to ctrl and I won't change that.
