TOSHIBA Power Saver

What is TOSHIBA Power Saver?

The Toshiba Power Saver / Power Management utility manages the power consumption of various devices on Toshiba notebook computers. Its primary purpose is to extend the amount of time that your machine can run from its battery or batteries. There are two primary power management modes: settings for running from the battery, and settings for running from the AC adapter. The default settings for running from the battery are designed to yield long battery life with reasonable performance. If, for example, the computer is left unused for a minute or two, the backlight for the screen (LCD panel) would turn off, thereby significantly reducing the power drain on the battery. By adjusting various settings and timeout values you can optimize the power management scheme more toward saving power, or more toward enhancing performance.


It is typically pre-installed with most new Toshiba computers. The most common release is 7.04.02.i, with over 98% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. The primary executable is named tpsmain.exe. The setup package generally installs about 21 files and is usually about 2.6 MB (2,730,266 bytes).

This program is pre-installed on the PC

Pre-installed software such as this is usually included by default on the manufacturer's PC. Many OEM (original equipment manufacture) software that is included with a new PC is useful and in many cases required for the PC to function properly as in the case of various software drivers. However, some pre-installed software is optional and can be safely removed.
