One reader asks, “How much does it cost to run my computer? How can I minimize this expense?”
That’s a pretty huge difference above. These are of course, opposite extremes. It depends on your computer, and your use. And especially if you use power saving options.
A typical desktop computer uses about 65 to 250 watts. Add another 35 watts for a flat screen (LCD) and 80 watts for old school large monitor (CRT). In sleep or standby mode? Just 1-6 watts!

Or, just run the following scripts on your computer for automatic setting changes:

One reader asks, “Should I turn my computer off at night? Would it save enough in the long run to justify? What about wearing out the switch?”
If you leave it on…
If you turn it off…
Switching a computer on and off every day versus leaving it on all the time is highly debatable, but I think most agree now days that with current technologies, it doesn’t make a difference either way anymore.

Here are 10 ways you can greatly extend the use of your battery’s charge while on the go. Extend, as in 30 minutes or more!
Solid state drives are available in some new laptops. They’re basically a huge flash drive instead of a hard drive at all. As they don’t have any moving parts, some manufactures advertise up to 18 hours of usage. Look for this option on your next purchase.
Need power while stuck in an airport? A Microsoft employee started this wiki to detail power outlet locations.
Wal-Mart, OfficeMax, and Radio Shack probably all have them. I found several suppliers online for less than $5. Here are some links if you prefer to shop from home:
(There are also some that convert a 110 home power outlet to a USB charger. That’d be great for traveling / hotels.)
Let me get right to the point: You need a UPS (Uninterruptable Power Supply, aka. “battery backup”) on most electronic devices you own, especially your computer. If you value your investment, or the data you have collected, don’t skimp here.
Without a UPS, your computer or other electronic device plugs into your electrical outlet and is subject to whatever voltage comes down the line. Low voltage (brownout), high voltage (spike or surge), or other conditions feed right into your device. This can cause minor damage or complete failure.
A UPS plugs into the outlet first. It conditions and protects the power it supplies to your computer. And they work well. If they don’t, most manufactures offer a warranty of coverage of ($25,000 or more) to compensate.
A UPS is commonly known to provide battery time to sustain your computer while the power is out. On a basic UPS you have 5-20 minutes, tops. This is enough time to save your work and shutdown. Or to prevent shutdown if your power is on the blinks. To provide sustained uptime, that would be a generator. 😉
Don’t wait for a problem to occur to take this serious. The common manufacture for UPSes is APC. Office Max sells these for $40 – $100.
