I still use a HP ZBook G2 from 2015, but the PWM flicker [1] is crazy. I'm not normally sensitive to PWM flicker, so I'm not sure what's going on with this particular screen. I could replace the screen, but if it's a structural fault, that just puts me out €100 without anything to show for it. Also, it's got another problem where the sound breaks whenever I (un)dock the laptop. I've reinstalled Windows and all the drivers, but that's solved neither problem. Perhaps it's time to move on. Can anyone else relate to this weird sense of defeat?
