Audio

This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.

Suspend mode

By default the system supports Suspend-to-Idle mode, which has increased energy consumption during sleep state:

# cat /sys/power/mem_sleep 
[s2idle] deep

To fix that you might want to switch to S3 mode (also known as Suspend-to-RAM or deep) by appending mem_sleep_default=deep to kernel parameters.
