Im quite new to linux. I bought a new laptop (Aero 15x w/ Intel 7th gen and GTX 1070 MaxQ) and made a fresh Ubuntu 18.04 install. Now I was trying to increase battery life as i get just around 3 hours or so, compared to ~7 on Windows.
I have TLP and Powertop and what I have found in Powertop is, that the network interfaces wlp3s0 (iwlwifi) drains around 14W which cannot be true.
I tried to ook it up and just found https://forums.whirlpool.net.au/archive/2551533 with the same problem but now solution. The people there were just talking that it is impossible for a wifi card to use so much power, so I would also guess that it is something with the nvidia gpu.
I run the 390.48, 4.15.0-20-generic driver and have nvidia prime installed but it is actually set to the Intel gpu.
Would really appreciate any help bc I dont want to use Windows but right now Ubuntu makes it really difficult for me.
PS: Im happy to give more information if needed.
EDIT: I found that this is a known bug in 18.04, that the eGPU does not turn off. It is already on Lauchpad: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765363 Should I keep my post here or delete it?
