Problem Solving

1.      Missing phone:† I would call the mall or store I was recently at with another phone and ask if they had found any phone.† I would call my phone as well, hoping someone would answer it.† Lastly, I would retrace all of my steps and see if I could find my phone.

2.      Losing battery life:† I would put my laptop in powersaving mode and or dim the brightness.† Not the most cost effective solution but buying a new battery would definitely fix the battery life problem.† Only using the apps or programs I need would conserve battery life as well.

3.      System password:† With any issue stopping you from working at your current job, I would contact a manager or higher ups and ask them for assistance.† I would assume the manager of the company I was working at would have some administration password to reset the password to one I would have made myself.

4.      Fan not working:† If my fan had recently stopped working in my laptop, I would attempt to open up the bottom of my laptop and make sure the fan isnít clogged, can still spin, and make sure it is connected still.† If that doesnít work, I would take it to a repair shop and see if they can diagnose the problem.

5.      No internet:† As big of a pain as it would be, taking a flashdrive with you and backing up your files would easily fix the issue of not being able to access the cloud to use your data.† The only other option would be to wait for the internet to come back on or go somewhere you can access it.
