#Lenovo legion 5 pro discharging too fast

Model: Lenovo legion 5 pro

Describe the issue: Battery is discharging at 30 watts, leading to a battery life of less than 2 hours

What have you tried already?: Set refresh rate to 60hz, completely disabled dGPU, set power saving profile on windows

When did it start producing the issue: Unsure. I had this same issue around a year ago and I somehow resolved it without figuring out what did it. I have been using it on the charger since then, and only noticed it recently when I used it off battery for the first time

Did you install new drivers or software?: it has been over a year so plenty of new drivers and software have been downloaded in that time. I couldn't tell you what specifically

Can you provide images/videos to show us the issue: there's not really anything to take a picture of. The battery is draining at 30 watts despite attempting everything I described

use vantage to set the GPU mode to Hybrid, then set it to Hybrid-iGPU

#

and the GPU should power off by itself after a few seconds.
if it doesn't, something's keeping the GPU awake and you'll need to diagnose that

scenic tusk
#

I tried setting it to igpu, and to hybrid auto mode, and it didn't fix both times

#

But now after setting it to hybrid first, I have 10 watts

ruby harness
#

if you just now enabled the GPU, reboot the laptop and then try switching to hybrid --> hybrid-iGPU again

scenic tusk
#

It's working now

#

Before when I chose those settings, they didn't work

ruby harness
#

are you in hybrid-iGPU now? is the GPU gone?

scenic tusk

.97GB wat

#

where are you reading that

scenic tusk
ruby harness
#

oh that's VRAM usage. that's a funny metric for vantage to use

#

anyways to check if the GPU is gone you should check task manager, performance section

#

you should only see a single GPU and that GPU shouldn't be Nvidia. if you see a Nvidia GPU then the GPU's not off yet

scenic tusk
#

Yes I only see intel

ruby harness
#

(or you get #legion-toolkit which is better at tracking GPU removal)

many things prevent hybrid-iGPU from working

#

usual culprits are

  • program that uses the GPU isn't closed
  • monitoring tool pinging the GPU - msi afterburner, hwinfo
  • connect a monitor - whoops a bunch of programs moved to the GPU and won't move off of it even after removing the monitor
    • using advanced optimus can cause this issue as well
    • #legion-toolkit has a nice "Restart GPU" button that solves this problem
#

there might be a tray icon that shows GPU activity - what programs are currently on the GPU. if the icon isn't there, it can be enabled in nvidia control panel, somewhere in the top menu bar

@scenic tusk saw your message in #questions, what happened?

scenic tusk
#

I'm guessing it's something pinging my dgpu but idk what

ruby harness
scenic tusk
#

It's weirdly laggy

#

It also just displays the icons but won't let me click on them

ruby harness
scenic tusk
#

I can't ss, but I'll take a picture of my screen

ruby harness
scenic tusk
#

Yeahhh

#

Idk why it's like that

#

Never used it before now

ruby harness
#

yeah that's not what that's supposed to look like

#

you enabled this right?

#

in nvidia control panel

scenic tusk
#

Yes that's the one

#

I'm trying restarting

ruby harness
#

i've never seen that indicator show icons and not a list of exes

#

well in any case it looks like there's a bajillion things running on the GPU, including onedrive.

#

which means a bunch of programs moved to the GPU

#

which happened because of advanced optimus

#

without #legion-toolkit kicking programs off the GPU is hard

#

so i recommend getting toolkit and using that instead of vantage
