Hardware Tips

Proper Cleaning of your LCD (flat panel) Monitor

Flat panel monitors make a wonderful addition to any computer. However, they do require more special care when cleaning than traditional CRT (Cathode Ray Tube) monitors. CRT monitors all have a glass front. LCD (Liquid Crystal Display) monitors, on the other hand, have a much softer face…almost membrane like. Because of this, LCD monitors are much more prone to being damaged from being touched and poked.

Rule #1:  Never touch an LCD monitor with your fingers or poke them with any object. Permanent damage can result.

CRT monitors can be cleaned in a myriad of ways because of their glass exterior. You can use water, glass cleaners, or just about anything that you would use on your windows at home. LCD monitors should never be cleaned with harsh chemicals of any type. Instead, if a liquid must be used, use only water or water mixed with a little rubbing alcohol. Some people even recommend diluted vinegar as well.

Rule #2:  Never spray any liquid directly onto a LCD monitor. Instead, use a soft cotton cloth and apply the liquid to it first.

When cleaning any kind of glass surface, it is common and acceptable to use circular motions and any number of cleaning rags are acceptable. As you probably guessed by now, LCD monitors are different. ONLY use soft, clean cotton cloths or special made LCD screen wipes that can be found in electronic or office stores.

Rule #3:  When cleaning your LCD monitor, do not rub in a circular pattern. Instead, use a side-to-side motion or up and down. And even then try to move your rag in only one direction. For example, wipe from left-to-right only or top-to-bottom.

LCD monitors can last a long period of time and provide you with excellent images IF you follow the simple precautions above to keep it clean.

Warning: External Hard Drives

One of my mantra’s over the years is about backup. Over the past few days, I have been working for a newer customer who hasn’t heard my sermons.

He had a "computer expert" setup an extremely complex home network and a NAS (Network Attached Storage) backup system. None of this is out of the ordinary. However, unfortunately, this was the only backup the customer had. Last week, his external hard drive failed. All of his important data existed on that drive that was seemingly lost.

External hard drives use the same hard drives we have in our computers with an added few components to allow the drive to function independent of a computer. Problem is that a hard drive is a hard drive…moving parts and all. Moving parts eventually fail and power can quit as well. These increasingly inexpensive devices work fine as a secondary backup…but should never by your primary drive.

Set up a home network – Part IV

This is our final installment of our networking tips. In this tip, you will learn how to share files and printers between computers on your network. One of the greatest advantages of a network for home users is the ability to use a single printer to service all the computers.

Windows XP offers a networking wizard that works quite well for most people to setup a home or small business network. You can find it by:

  1. Double-click the "My Computer" icon
  2. Click "My Network Places" from the task list on the left of the screen
  3. You will then see the menu of options at the pictured here
  4. Click the "Set up a home or small office network" option
  5. Click Next twice
  6. The next screen will ask you how you connect to the Internet, choose the second option "  This computer connects to the Internet through a residential gateway or through another computer on my network."
  7. Click Next
  8. On the next screen, give your computer a description and a name as described in the step itself
  9. Click Next
  10. Now you name your network (workgroup) so that the computers can talk to each other. Use any name you like, but keep it to a single word like; Steelers, Network, Rover, etc
  11. Click Next 
  12. Click the "Turn on file and printer sharing" option
  13. Click Next twice
  14. If you are using Windows 98 or Me on other computers in your network, then click the "Create a Network Setup Disk" and click next.  OR  If you are using XP on the other computers, then click the final option "Just finish…"
  15. Click Next  
  16. Click Finish

Using this method will allow you to share files through the "SharedDocs" folder found in My Computer. Any files you save into this folder can be accessed on any other computer via the network. The wizard will also allow you to share any printers you have installed.

Set up a home network – Part III

This is Part III of our ongoing series regarding home and small-business networks. You can read the first two installments here:  Part I and Part II.

In Part II, we discussed how to use a 'wired' system with Ethernet cabling to connect your computers and broadband connection. We suggested that you purchase a Wireless Cable/DSL Router with 4 port switch to connect your computers. The reason we suggested a wireless router is two fold; 1) The cost is only a few bucks more, and 2) Having the wireless gives you the ability to easily add a laptop or computer in another room to your network.

Typically, wireless routers can broadcast a signal that will reach around 75' indoors. However, that number reduces significantly depending on the barriers it has to pass through…walls, ceilings, type of walls and floors, etc. For best results, I like to keep the wireless computer as close to line of sight as possible to the router (least number of walls and barriers like furniture). Currently, the standard used in wireless computing (wi-fi) is 802.11g. For those with inquisitive minds, you can get detailed definitions of all terms wireless at Webopedia. This link is a comprehensive list of wireless networking terms. 

As with the wired setup, use the CD that came with your brand of router to walk through the setup. The first thing you want to do is assign a new password (right it down and remember it for future use) for the routers settings. Most of the wizards offer you the chance to do this right away.

Next, you want to setup the wireless security for your system. Enabling wireless security drastically reduces the chances of a hacker trying to break into your network. The first step you will be asked to do is assign a name (SSID – Service Set Identifier) to your network. Don't use your name…use something like your street name or high school mascot or development name…etc. Again, right this down and don't forget it. You will also be given the opportunity to broadcast your wireless name or not…for ultimate security, click "No" on the broadcast option. However, for ease of setup, as long as you are following the rest of the security steps, broadcasting should be ok.

Broadcasting your wireless names allows computers with a wireless network card to see what networks are available. If you are broadcasting you need to be secure.

Set up a home network – Part II

Last week we introduced you to some networking terms and technologies. This week, we will show you how to start building your network.

In these instructions we discuss how to setup a network for sharing the Internet, but if you only want to setup a network for sharing files and printers without broadband, simply leave out the broadband modem and these instructions will still apply. 

One term we did not define last week was Network Interface Card (NIC). Currently, there are two main types of NIC's. Wireless and wired. A NIC is a device that is connected to your computer that allows communication with other computers (networking). This can be done either through wireless means or wired means with an ethernet cable.

All computers that you want to network need to have a NIC. You choose whether it is wireless or wired. Almost all computers built since 2002 have an internal NIC for networking right from the factory…even laptops. Almost all laptops built since 2004 have built-in wireless networking capabilities as well. If you need to add one to your computer, a NIC will cost between $10-25. A wireless NIC will cost around $40.

Remove Bios Password

There are two solutions to this:

Solution 1:

Try some of the backdoor passwords that are often built into the BIOS following the setups on this site.

Solution 2:

  1. Turn off and unplug the computer
  2. Open the computer and look for a flat "watch" battery on the mother board
  3. Remove this battery. You may have to gently pry it out using a small tool.
  4. Plug your computer in and turn it on without the better.
  5. Turn your computer off and reinsert the battery and turn the system back on.

 

When Should You Use the RIGHT Mouse Button?

Many people ask me when is the appropriate time to click the RIGHT mouse button. My short answer is to try it everywhere. The RIGHT mouse button (or secondary mouse button) provides quick access to many common functions via a pop up menu. And those functions change depending on what program you are using and where you are in that program.

For example, in almost any application, if you click the RIGHT mouse button, you will have access to cut, copy, and paste. If you are in email, or the Internet or a word processing program any you need to copy some text to another area, first highlight it then RIGHT click on it to quickly get to the Copy function.

Utilize ALL of Your Screen Real Estate

DISCLOSURE: If you don’t feel comfortable making adjustments to your system, please don’t proceed with this tip.

Take a look at your monitor right now… Do you see a black border surrounding the screen? If so, you can quickly and permanently regain that extra viewing area by following this week’s tip.

Because there are many different types of monitors and manufacturers, I can’t be specific to your machine, but follow the guidelines laid out here to make your adjustments.

At the bottom of your monitor, you will notice either a series of buttons or maybe a dial.

If you can find your monitor manual, then it will explain what the buttons mean and how to use them to make adjustments. If not, look for the following visual hints on the buttons or possibly on the screen itself after you press the buttons:

Use Your Digital Camera to Take Inventory

Planning for a disaster seems almost pessimistic to some, but in the long run, planning for the worst can save you. I talk about backup of your important digital data all the time, and this week’s tip takes the term backup a little closer to home.

One great, practical use of your digital camera is to take inventory of your personal belongings. Use your camera to photograph your heir loom china, your classic car, your stereo and TV equipment, your video collection, appliances, and furniture. Because you don’t have to worry about film, take pictures of anything and everything of value to you in and around your home.

Unique Digital Photo Holiday Gifts

You’ve take a bazillion digital photos so far this year or have a shoe box of great old photos. This holiday season, put those photos to fun use by creating unique gifts with them.

Using tools you already have, you can create photo t-shirts, aprons, and carry bags. All you need is the perfect photo, an ink jet printer, an iron, and special iron-on paper. Ink jet iron on paper can be found at any office supply or large retail store. All the major ink jet printer makers make their own brand of iron paper, and I suggest matching the paper with your printer.

Use any photo editing or publishing program to come up with a fun design, then print it directly on the iron-on paper. You do have to remember to print the ‘mirror or reverse’ image of the design so that it transfers properly to your project. To find the mirror or reverse option, click to the properties or settings section of your printer before you hit the print button.
