For curiosity, tried pricing out this laptop preinstalled with Fedora, and it won't let you choose any ram option other than the lowest unless you switch to Windows.

Looking for a new laptop that runs Linux out of the box? Get a ThinkPad!

Lenovo has been offering ThinkPads with Fedora and @ubuntu preinstalled for a few years now. The more people who shop for these devices, the more attention they can give to this business!

Here's an article of someone discovering Lenovo's Linux program: news.itsfoss.com/lenovo-cuts-w…

Lenovo Cuts the Windows Tax and offers Cheaper Laptops with Linux Pre-installed

Lenovo is doing something that many aren't.

I am profiling #GNOME Shell (MASSIVE thanks to #fedora enabling frame pointers for all packages in 38 making this possible) and noticed clock_gettime() taking up a huge chunk. Turns out I hit
bugzilla.kernel.org/show_bug.c…: many #AMD laptops are forced to use a very slow clock source (HPET instead of TSC). #Lenovo fixed it with a BIOS update for some laptops but not mine. :sadness: Kernel param tsc=reliable results in big speedups (up to 30% in browser benchmarks) but unsure if it impacts stability :/
Flame graph profile of gnome-shell showing clock_gettime() taking ~10% of the time. Particularly, most of the time is spent in the read_hpet() function that reads the slow HPET clock source.
Results of three benchmarks from https://browserbench.org/ on Fedora 38 and Firefox from Flathub, comparing TSC versus HPET clock source. The results: JetStream2 82.722 (TSC), 76.437 (HPET); motionmark 311.47 (TSC), 236.40 (HPET); speedometer 88.9 (TSC), 79.5 (HPET).

202525 – TSC marked unstable on AMD Ryzen 2000

I like #Lenovo for how easily accessible #service manuals their laptops have. 👌🪛 💻

Funny is, the laptop I am fixing now has the usual warning for powering off the device and disconnecting the power cord and battery. Or here literally to remove the battery pack. But actually you have to disassamble half of the machine to disconnect the battery. And then the rest of the machine to remove the battery. There is even no option to disable battery in bios. 😀 ⚡🔋

Screenshot from service manual: Danger! Before removing any unit remove the battery pack.
Another screenshot from service manual: To remove battery pack you have to first remove hard disk, pci express slot cover, wifi module, optical drive, keyboard, optical drive board, usb board, main board...
