Agreed. I got a gen10 thinkpad (with Linux). The power supply makes a crackling noise. After 6 months the fan starting making grinding. The screen flickers when the CPU is loaded, and once a week the whole thing just locks up. Worst laptop I've owned.

Yes, and the fan blows directly onto your mouse hand, making mouse usage awkward as well.

Actually this is my favourite feature of my work thinkpad. Especially during winter. Really. Besides tons of disadvantages of the platform for the price.

Did work install any crapware on the laptop? Or is it bad even without?

The software is fine. The computer isn’t slow at all. It’s just not a well designed computer.
