The early Lenovo period W series were (imho) very good as well, still have my W500 series which is built like a tank. Survived years of college, years of lugging it around to customers and data centres and having somebody spill a full cup of coffee over it (yes, the drain holes do work!). It only required replacing of the monitor cable once, which was a pretty easy thing to do. Unfortunately the CCFL backlight has lost quite some luminance by now, but guess after 16 years that is to be expected. Can’t get myself to part from it though, so many memories attached to it.

Or SuSE Linux, the non-slackware or jurix version was bleeding edge at the time.

This has nothing to do with Lenovo perse, this is the average experience for every laptop I’ve owned which had Secure Boot turned on.

You know what is fun? Having your Dell basically bricking because Fedora starts shipping a new version of shim-x64 which completely fails the UEFI handover to bootloader. Leaving you unable to boot at all, so no chance of reaching rescue mode. Then more fun times of booting a live environment from a usb stick after going through the same hoops you went through, finding out how to decrypt your BTRFS partitions, manually mounting and chrooting them so you can finally downgrade the offending package.

Linux and Secure Boot just isn’t a great combination if you ask me.
