Problem Solving:

1.       You could resolve this by running a scan on your computer to check for any type of malware that may be slowing your computer down. Also one thing I like to do is go through most of my files and see which ones I can get rid of. One good program is a disk defragmenter which will help clean up your hard drive.

4. Usually when your battery drains quickly means the life of the battery is weakening. Apple iPhones now have a new feature showing the overall battery life left in the phone. There could be apps running in the background that are very battery intensive as well.

5. Personally I would shut my computer down and disconnect from the internet. I would then boot up in safe mode. Depending on what I saw on the link I have a safe boot saved on a flash drive which would allow me to clean up my computer. If I didnít think it was a big issue I would run a scan with my antimalware program.

9. My first step would be to restart the computer because maybe the crash caused an error in the system and properly resetting it may solve that issue. Next I would try to connect to the cloud service using a different device. If none of those options worked I would call the IT department.

10. The next steps would be to try and find a cable that fits both the laptop and the projector. If none can be found then try and find a convertor (Ex. VGA -> HDMI). If that doesnít work transfer your presentation to somewhere that it can be easily accessed from and try a different device.
