18.04, factory install from Dell. It's the 4k model, no TLP as far as I can tell (apt list --installed | grep 'tlp'). I haven't changed anything in the OS other than installing a variety of packages.
I'm starting to think that the display drivers might be the problem, if they're different between the 4k and 1080p models.
The update issue now that I recall was this:
https://github.com/fwupd/fwupd/wiki/LVFS-Triaged-Issue:-AC-power-required https://github.com/fwupd/fwupd/wiki/LVFS-Triaged-Issue:-AC-p...
But plugging in the charger to a USB port wouldn't register as "AC Connected" and the error would persist. Appears to be working now however.
- ZeroCool2u 7y agoWell there's not much to do about the drivers, but report your bugs to the intel iGPU team and Dell. Try setting up TLP and see how your battery life changes. I've tried doing without and the difference is huge.
- NotSammyHagar 7y agoI have the same as this guy. official dell os, no added drivers, updated to all changes, did some recommended bios update. 4k screen, less than 5 hours. it occasionally won't put up the login prompt when locked - it moves the mouse but bit it won't put up the login panel. Thus I have to power off to reboot. The late 2019 4k is a lemon. I tried to return it and they wouldn't take it back. I got it in mid Dec, figured they would update the drivers and tweak it to get better battery, but it never happened by mid jan. then it was too late.
- ZeroCool2u 7y agoDamn, that really is too bad. It sounds like you might as well go ahead and just upgrade Ubuntu to 19.10 to see if it helps. You don't really seem to have anything to lose at this point. I've seen huge improvements between what I originally had with the stock 18 LTS OS and now 19.10.
