This method, once enabled, will use Lenovo's built-in Custom TDP mode.
Note that this requires the acpi_call module, if your distro doesn't have it pre-installed, it'll have to be manually installed.
To check if you have acpi_call, run sudo modprobe acpi_call in terminal. You should see no errors.
This also requires the v28 or newer bios.
Make sure you have the latest SimpleDeckyTDP installed, and enable STAMP in the bios.
install/update to latest SimpleDeckyTDP with: curl -L https://github.com/aarron-lee/SimpleDeckyTDP/raw/main/install.sh | sh
If your device is compatible, enable the Lenovo Custom TDP Mode advanced setting in options:
You'll know it's working if it changes the power LED to purple when you set TDP via plugin
The ROG Ally has two extra options:
- Enable Platform Profile Management
- Enable TDP via Asus WMI
Platform Profile Management helps the Ally auto-manage fans
Asus WMI enables TDP control even with Secure Boot enabled
For anybody that needs more fine-grained fan control on the ROG Ally, I'd recommend the PowerControl Decky Plugin, but note that it conflicts with SimpleDeckyTDP, so you'd need to uninstall it.
As an alternative that is compatible with SimpleDeckyTDP, there is a fan-curve-only fork of PowerControl I created for personal use on my GPD devices found here Other users have reported that it works on the ROG Ally
