I’ve suspected for a while that this laptop is using a lot of power in standby mode (suspend to ram). Usually I use standby only when charger is connected, otherwise I use hibernate (suspend to disk). Now, however, I but it into standby and placed it in a bag for a 30 minute travel. When I unbagged it I realized that it was hot. So I did a test: Fully charged, I unplugged to charger and placed the laptop in standby. Exactly 10 hours later I powered it on 37% of the battery was left. So it consumes 6.2% of the battery /hour in standby mode.
For comparison, if I turn off wlan, BT and put screen on lowest brightness, it consumes 3,52%/hour. And with wlan and BT on and screen at my usual working britgthness level, it consumes about 4.3%/hour. So battery drains way faster in standby than when powered on.
Is there anything that can be done to reduce power consumption in standby mode?
