TLP 1.11 drops for Linux power management, shifting profile naming to _PRF, _BAL, and _SAV with automatic runtime config translation.
It introduces multi-alternative profile testing, independent wireless profile rules, PL2303/CH34x serial exclusion from USB suspension, and a fix for battery care on non-ThinkPad Lenovo laptops.
New naming convention for energy profiles
The most significant change concerns the operating profiles, which now use the suffixes _PRF, _BAL and _SAV instead of the older naming system based on the connection to the power outlet or battery. The old settings remain compatible thanks to an automatic translation process that occurs while the system is running. Users who want to identify which parameters need to be adjusted can use a specific control command.
Better control of hardware and devices
Settings can now cycle through different options until they find the right one for your system. For example, the high-performance profile favors a more balanced option when available, which can reduce fan speed and noise on some gaming laptops. The power-saving profile can also revert to quieter options, while wireless devices can be adjusted individually in each profile.
On USB ports, the program now automatically excludes certain serial communication devices from being suspended. Users who want to suspend these devices can manually add them to a special whitelist. Additionally, startup files and scripts are included for systems that do not use basic modern service management methods.
Fixing battery problems on laptops
The new release resolves a battery charging issue that affected some non-ThinkPad laptops, including ThinkBooks. The issue occurred because the charging status became unreadable after the computer was suspended or hibernated, due to an issue related to the operating system kernel. TLP works around the issue by re-updating the relevant setting once the computer is back on.
