Welcome to the Laptop Mode Tools wiki

Laptop Mode Tools is a laptop power saving package for Linux systems. It allows you to extend the battery life of your laptop, in several ways. It is the primary way to enable the Laptop Mode feature of the Linux kernel, which lets your hard drive spin down. In addition, it allows you to tweak a number of other power-related settings using a simple configuration file.

Installation Install a package from the packages page. If you are going to use this on a non-laptop machine, be sure to read the FAQ first.

Support If you experience any problems, be sure to check the FAQ first. Otherwise, Open a ticket, or ask a question on the mailing list. If neither work, you can send an e-mail to Ritesh Raj Sarraf

Some common problems and fixing them

My USB Mouse / Keyboard stops working after seconds of inactivity

Many devices advertise power savings but misbehave when power savings is triggered. Laptop Mode Tools, by default, enabled power savings for all devices.

If you have devices, that mis-behave when running on battery, you can blacklist them.

For details on blacklisting the device, please refer to the configuration details in /etc/laptop-mode/conf.d/runtime-pm.conf
