Please turn off your computer at night ...!

There are several reasons why it may be a good idea to turn off your computer at night. For some, it may not matter whether the computer is on or off. Most newer computers have a sleep mode when they are inactive which doesn't use much power. However, in businesses or at home, it may be wise to turn off the computer at night for security reasons.

For example, computers connected to the Internet via DSL or cable modem are vulnerable to hacking if they are still connected. You can either turn off the connection or turn off the computer. You may need to keep the computer turned on, conversely, if the computer is used as a fax machine as well.

However, if you work from home and log into a business, you should definitely turn off the computer at night, or at the very least, log out from the business. Not only does leaving the computer on threaten the security of your personal computer, but it could also give hackers entry to your business.

Sleep mode on computers still uses some electricity, and the most economic thing to do is to turn off the computer at night, especially if you're is penny pinching. Saving electricity also has environmental benefits. Older computers may not have the sleep feature, so if you have an older computer you might want to turn it off to save money. Obviously, laptops, which run on a battery, will have a longer battery life if they are turned off when not in use.

You may turn off the computer out of the common misconception that this will protect the computer from power surges. Actually, this is not the case. Even when people turn off their computer, the computer is still vulnerable to power surges if it's not hooked up to a surge protector. Be sure to purchase a good surge protector and do not skimp on money in this case. Find a well rated one that will protect your computer whether off or on from power surges.

Some computer experts suggest that certain programs benefit from getting a break at night, like Windows®. Turning off the computer at night may help eliminate crashes during the day, since the program is rebooted when the computer is turned on again in the morning.

If you aren't concerned about money, computer security, and crashes, then you don't have to turn off the computer at night. But, since at least one of these issues is usually a concern, you might want to turn off your computer at night.
