MEM_SLEEP_ON_AC/BAT

Version 1.6 and newer

MEM_SLEEP_ON_AC=s2idle
MEM_SLEEP_ON_BAT=deep

Select the system suspend mode:

• s2idle - Idle standby, a pure software, light-weight, system sleep state

• deep - Suspend to RAM, the whole system is put into a low-power state, except for memory, usually resulting in higher savings than s2idle

Caution

Changing suspend mode may lead to system instability and even data loss. As for the availability of different modes on your system, check the output of tlp-stat -s. If unsure, stick with the system default by not enabling this.
