Why is it so importance to shut down your computer when you can just close the lid and be done with it? The answer for this is two words: “longevity” and “reliability”.
Before you normally put your Mac/PC to sleep your computer has several files open, even when you do not have any windows open. The majority of them are temporary files, but even so, such that the Mac/PC System Files are still being used. Shutting down allows the computer to correctly close all running programs and update the registry as well as any other data files or caches attached to the program.
If you always allow your computer to sleep and never properly Shutdown in Days or Months these may end up not working correctly and may become corrupt. Furthermore, without shutting down at least once a day, your computer components (ie. Hard Drive, Processors, and etc.) inside will eventually fail. Early signs of such problems are audio malfunctioning, display not connecting, inability to connect to SMART boards, USB ports not working.
The correct way to shut down a Windows PC is to click on the “Start” button. What you do next depends entirely on how Windows is set up on your PC. You may have the option to “Shut down” on the pop-up menu, but if you do not, then click the little arrow near where the Shutdown option would be and select it.
The correct way to shut down a Mac is to go to the Apple menu and choose “Shut down…” Sometimes when prompted by an Installer program to restart, the program will present you with a Shut Down option, which will generally occur after installing in a new update from Software Update. On some Macs, you can press control-eject and select “Shut Down” from the window that pops up. On other Macs, you can press the power button and choose “Shut Down” from the window that pops up.
Missing audio is one of the biggest problems facing most of the student body lately as well as teachers in their classrooms. The story behind these issues is very simple: they mostly occur because of power problems. They could occur if there was a spark between the audio connector and the laptop. The connector may have been improperly pulled out while computer was sleeping. In truth, like Edison use to say, “there are a million ways things can go wrong.”
The Fix is very simple on Macs, but a little harder on PC. The first step to fixing this problem is to properly Shutdown the computer while plugging in. Following these instructions has proven to be the best method in fixing such a problem for both the Mac and PC.
Broken Projector Connection is another issue in classrooms everyday. Again, the reason for this is improper dis-connection while the computer is asleep. Sometimes when hurrying out a classroom to go to another, you may be tempted to slam your screen down and immediately pull the dongle out afterwards.
This is a very bad habit. Many problems can occur from this even un-fixable ones: permanent malfunction of the connector ports of the laptop, Graphic Card Crash, and eventually short circuiting the Circuit board inside your laptop.
Best Practices however includes properly pulling out the dongle before closing the lid of your laptop and avoiding plugging in a projector while the Laptop is sleeping or the lid is closed
But If Things Do Go Wrong the best way is to Shut Down Both the Monitor and the Laptop . Then re-start the Laptop followed by the Projector/Monitor. In extreme cases if that fails as well, try to test the connection with another dongle at hand, or call us at ext.670
Hard Drive Failures
Hard Drives in colloquial terms, are basically CDs and motors on steroids. The Disks inside of these Hard Drives spin at around 5400-7200 rounds per minute. That’s around 120 times a second. They spin endlessly while powered on and even sleep modes, thus the reason they deserve a mention on this page. Every Hard Drive on Earth has a life expectancy that very well varies through each user scenarios. In perfection conditions of no movement, containment , and a chilled temperature of around 25 degrees Celsius, they could in theory last for around 600,000 hours. However in real life that is impossible. From past experience these spindling motors could last up to 3 to 4 years tops if taken cared of very carefully.
However due to their moving nature Hard Drives will die if dropped, shaken, overheated, there is inconsistent power, a power surge, a malfunctioning battery, or the loss of power, and the list just goes on. But fret not, if you had never shaken your laptop violently, or shut it down occasionally, and never dropped it more than perhaps twice, then you're good to go for quite some time.
If NOT occasional Backups are recommended.
