Do you sleep, standby or hibernate?

Last year we looked at your need to shut down your computer. Today, we are going to look at the power settings. Computers have definitely improved over the years when it comes to power management. There are three different states (or settings) depending on the Windows operating system.

To Sleep, Perchance to Dream - Putting your computer to SLEEP, means that everything stays the same, like pausing a movie. It reduces power, stops what it is doing (while keeping your information in memory) and allows a quick wake up. Sleep draws a small amount of power but much less than leaving it running. If you loose power, you will lose your settings and anything not saved to the hard drive.

Stirring Suddenly from Long Hibernation - Hibernation is designed for laptops. When you 'hibernate' the computer, it saves the information (called an image) of what you are doing at that time from the memory to the hard drive then turns the computer off. When you turn it on, it restores everything as you left it, but it will take a little bit longer to start your computer after hibernation, just like some of us get grouchy after oversleeping.☺


We're Back to the Old Standby? - Also found on laptops (XP), standby means you are running your machine in a very low power mode to save battery power. (This is very similar to Sleep mode.

So why would you use these settings over shutting down and booting up? Because it actually takes more energy to do that than putting it to sleep or into hibernation. Sleep is quickest but hibernation actually loads quicker that a boot up as well.


Side note... With a laptop, if you put the system to sleep (save in memory) and your battery runs seriously low, Windows will automatically put the laptop into hibernation mode.


So now you know! Tomorrow we will look at how to change those power settings so stay tuned!

Typing Exercises

You took typing but need to increase your typing speed? Job interview or just because? Typing has become critical in this computer based world, not only from the workplace but also resumes and communication now rely on the keyboard instead of pen and paper. I took typing in high school before corrective ribbons were on the electronic typewriters. I was lucky to get to 15 WPM, and that was on a very good day. My typing teacher was awesome. It really wasn't her fault that I just was not that coordinated and often made mistakes reducing my numbers to single digits. Fast forward to today, I teach Microsoft Office and often encourage my students to start or refresh their typing skills by increasing their speed. The website I use for  "learning to type" is typingclub.com where you can easily learn the basics to more advanced techniques. Yes there are advertisements although you can pay for an ad-free premium. I don't benefit from this suggestion, but found the 684 lessons ...

Is Your Website Ready for the Search Engines?

  Photo by sarah b on Unsplash Let's be clear. When it comes to search engines, keep in mind that SEO is an experiment, there are no rules. The  algorithms changes regularly (estimated 400 times a year) and Google doesn’t share specifics on those changes except general guidelines on their site.  That being said, there are some best practices to help improve the rank of the website. We can't cover all of them here, but there are some obvious ones. This applies to the majority of search engines, so don't feel like you need to cater to each one individually.  Most of all, if this is greek to you, consider hiring someone to handle your SEO. Also, if they make promises of specific results, run far away. SEO is a slow, continuous process. Make Your Content Clear According to Google, they want to "see your page the same way the user does".
