I've got a Dell 7490, which works great for development, and you can upgrade the SSD and RAM, but, suspend is unreliable.
TBH, the only issue I've had with any of my laptops in Linux (Dell and IBM/Lenovo) is suspend. Which actually makes me think power management in general might be busted.
I'd be interested to know if there is a methodical way to diagnose these issues? Every howto just seems to be a mishmash of kernel flags to try, which seems chaotic, and gets frustrating when the issue is intermittent.
- theossuary 4y agoThis [1] is the OG guide to debugging suspend/hibernate issues. Arch Linux Forum [2] is also a good source for this. That said I've spent months debugging hibernate issues without success, it really is a crapshoot of driver support.
