How I stop iCUE's crazy battery drain on my Legion laptops

2021-09-10, 6:48 AM

You can safely install iCUE v3 or v4 and run it to create your preferred RGB setups with static colors for any or all zones (static color profiles only as custom animated RGB profiles will halt when iCUE is stopped). You'd then make sure your favourite customized RGB profile is the first in the iCUE profile list as that'll be the one that gets activated upon iCUE startup. From there you can create a batch file like below, create a shortcut to it ("iCUE Battery Saver" for example), customize that shortcut via its properties (right click), add a shortcut key combo (such as setting it to CTRL-ALT-Z, etc), set it to run minimized and, optionally, set it to run in Administrator mode. Finally, move or copy the customized shortcut in to your Start Menu's Programs folder (%AppData%\Microsoft\Windows\Start Menu\Programs).

From then on, you could either click to run this from your start menu or tap the keyboard combo you created... from anywhere in Windows (except with full-screen apps or games activated). Doing this will auto-kill the running iCUE v3 or v4 process and its services while leaving the loaded RGB profile in tact in v3 (until reboot or hibernation). If you are using v4 of iCUE, it'll revert your RGB setup to the stock firmware "Rainbow", but at least iCUE won't kill your battery or CPU anymore. If running v4, I'd run this batch via its shortcut every time you unplug, then run iCUE again, if desired, once you plugged back in (you could modify iCUE's own shortcut to add a separate key combo for quick access anywhere in Windows). Using v3 of iCUE is preferred as, again, your custom static RGB lighting will remain active even if iCUE and it's services are terminated (until reboot or hibernation). If your Legion 7 or 7i doesn't have any stuck pixels running iCUE v3, this would be the best option.

Here's a simple icue_killer.bat file one might create:


@echo off

:: Terminate the iCUE 3 or 4 process if running
echo Shutting down Corsair iCUE:
taskkill /IM "iCUE.EXE" /F

:: Stop the three Corsair v3 services (and one more with v4) if running
:: - the first process requires admin mode to stop, the other three do not
:: - the last process is the one that consumes the most battery
:: - you can get away with not running this in admin mode if desired
echo Stopping the Corsair Gaming Audio Configuration Service:
net stop "Corsair Gaming Audio Configuration Service" /y
echo Stopping the Corsiar LLA Service:
net stop "Corsair LLA Service" /y
echo Stopping the Corsair MSI Plugin Service:
net stop "Corsair MSI Plugin Service" /y
echo Stopping the main Corsair Service:
net stop "Corsair Service" /y

One could use Windows task scheduler to automate this by running these commands when AC power was unplugged, then starting iCUE back up whenever AC power was restored... there are lots of other ways this could be changed and customized but this simple example works fine.

Takeaway: this may not be elegant, but it at least fixes this problem until Corsair gets off its lazy butt and re-writes their terrible software (after all these years!). I wish Lenovo would sever their Corsair relationship once and for all and code RGB control directly in to Vantage, but alas. With this batch and shortcut, you can still have iCUE installed to take advantage of all the RGB goodness on these beautiful machines (again, static color profiles only as custom animated RGB profiles will halt when iCUE is stopped). A simple and easily accessible keyboard kepress will stop iCUE from destroying your battery life and even avoid stuttering, etc in Windows for some non-gaming tasks. When you want iCUE back, just run it again.

Best to you all.
