# Deep sleep

{% hint style="info" %}
Your power meter will enter a light sleep after 90 seconds of inactivity. A little movement will wake it up again. But if you are done for a few days, it is better to put your power meter into a deep sleep to best conserve your battery. 

You will need your charger to wake the shaft up from this deep sleep state, so keep that in mind before placing your power meter into deep sleep. 
{% endhint %}

Connect to your power meter with the Web app and navigate to the configuration page

Click 'Confirm' and your power meter will disconnect and shutdown.

When you want to wake your power meter up, simply place the charger on the shaft as if you were going to charge it. It should only take about 3-5 seconds for the charger to wake up your power meter.
