Screen at 400 nits is comfortably visible outdoors, compared to a Pavilion 15" 300 nits, which was barely legible. Trackpad operation is very smooth; the numeric keypad is nice to have. i5 processor speed is fine - compiles are about 15% faster than an i5-8265U. Notes: something (either a BIOS upgrade or a Windows 11 upgrade) reset some performance-related BIOS settings: compiles were twice as slow after the upgrade(s), until I fixed the settings. Also, (left) Ctrl and Fn were swapped. Turns out there's a BIOS setting to do that in the Elitebook BIOS - I didn't see it in the Probook BIOS.
We’ve had nothing but problems since day 1, I guess I’m going to have to take it somewhere to have it looked at. Which really irritates me since it’s brand new. I definitely would not recommend it.
