A brief press will turn the unit off (i.e., suspend the unit). Powering back on from suspend is faster than powering on after a shut down; however, LabQuest will continue to slowly drain the battery while suspended.<br \/>\n<b>Note: <i>You don&#8217;t get feedback on the button press until you let go of the button.<\/i><\/b><br \/>\n2. If you hold the power down for 5 seconds, a message will appear and advise that LabQuest is going to shut down. This method is recommended when you will not be using LabQuest for extended periods of time.<br \/>\n3. If you continue to hold the button down for a total of 8 seconds, the unit will power off uncleanly. This is the same as pulling the battery out of the unit while it is running.<br \/>\n<b>Note: <i>This method should only be applied if you have no other options as it can potentially lead to file system corruption.<\/i><\/b><\/p>\n<p><a href=\"\/til\/2018\/\">What is the best way to store LabQuest units over summer vacation?<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>This information pertains to LabQuest 2 and LabQuest 3.
