Sometimes applications can rapidly drain the battery charge of your computer. On a full charge your battery should last a full school day (8 hours). Spotify  and Google Chrome  are known to rapidly drain the battery life of the computer, although other applications could also be draining your battery. 

If you notice that your laptop is running out of charge quicker than usual, Close Any Unnecessary Applications. If you are running Google Chrome , Remove or Disable Any Unnecessary Extensions. Check out the link at the bottom of the page on how to do this. If this still doesn't improve the issue, come to see 1 Degree to have the situation assessed.

Always remember to charge your laptop overnight!
