Enabling Handheld Companion
Open up Handheld Companion.
Handheld Companion needs to be launched prior to any game launcher so you want to make sure that all game launchers are closed prior to starting the service. I personally don’t have any game launchers starting at launch with Windows.
Go to Settings and enable Auto-Start, Open application in background and Close minimizes. (This is a personal preference.)
Go to Hotkeys tab on the left. From here you can set up Hotkeys for different functions in the app. We want to create a hotkey for the quick tools window, I chose the Legion R button since I have Legion Space disabled until Lenovo fixes it. You can choose whatever input you want though.
Now you can press the hotkey at any time to bring up the Quick Tools window and make it disappear.
Handheld Companion is now Enabled and has a hotkey function.
Go to the Profiles section, Turn on Thermal Power (TDP) limit
Change the TDP to whatever you want. For my example I changed it to 18W.
You can also change the TDP in the Quick Tools menu.
Go to the Profiles tab, scroll down and click Controller Layout.
From here you can remap every button the Legion Go.
In Profiles – Controller Layout. Click the Gyro tab up top.
You can choose whether you want the gyro to act as a joystick or mouse.
You can then adjust the activation buttons and more gyro settings.
This can also be enabled and disabled in the Quick tools menu.
Disabling Legion Space
In order for Handheld Companion to run properly, you need to disable Legion Space on your Legion Go.
Press the Start button on your Desktop, search for Services.
Inside Services, right click DAService and click properties.
Change the Startup type to Disabled and click Apply.
Legion Space will not be active no more. Change it to Automatic to re-enable Legion Space if you want to use it again.
