ThinkPad leaks electricity even when powered off

June 29, 2014

When a ThinkPad is shut down, it may still consume electricity from the battery. This is because some devices are using energy even without performing their main function (normally for waking the laptop in some circumstances). This can kill the battery if the laptop is not used for a long period of time and unplugged.

To find out what devices are using energy when powered off, type the following command in Command Prompt window (cmd.exe):

powercfg /devicequery wake_armed

Then go to Windows Device Manager to stop the listed devices from waking the laptop (untick the option).
