Any law enforcement official can tell you that a few extra steps of caution can avoid a disastrous theft. Thieves enjoy convenience just as any shopper does; if your laptop is more difficult to pinch than the next guy's, it's the next guy who loses.
Mark your laptop

Marking your laptop helps with the recovery of a stolen (or lost) laptop. Either engrave your information onto your laptop or use a tamper-resistant asset tag. After all, the best proof that something is yours is your name right there on the stolen item.

You can use an engraving tool to literally carve your name and contact information on your laptop.

Some clever folks merely write their names inside the laptop, either on the back of some removable door, inside the battery compartment, or other places a thief probably wouldn't think to check. Use a Sharpie or other indelible marker.

You can get asset tags from most print shops. The tags peel and stick like any sticker, but you can't easily remove or damage them.
Don't use an obvious laptop carrying case

That carrying case with the emblazoned Dell logo (or IBM logo, or what have you) isn't just a proud buyer appreciation/marketing gimmick. The custom laptop case tells the casual thief that something valuable lurks inside.

In contrast to a loud-and-proud custom laptop case, a non-descript, soft laptop case doesn't draw undo attention to your computer. Backpacks also make good places to store laptops.
Register the laptop and its software

Be sure to send in your laptop's registration card, as well as the registration for any software that you use. If someone steals the laptop, alert the manufacturer and software vendors. Hopefully, they care enough so that if someone using your stolen laptop ever tries to get the system fixed or upgraded, your registration information helps you locate the purloined laptop.

This trick assumes that the person fencing the laptop doesn't fully erase the hard drive.

Be sure to keep a copy of the laptop's serial number and other vital statistics with you, specifically in a place other than the laptop's carrying case. That way, you know which number to report to the police, as well as the manufacturer.
Be mindful of your environment

When you're out and about with your laptop, stay aware of where your computer is and who may have access to it. Watch your laptop!

For example, when dining out, put the laptop in its case beneath the table. If you need to leave the table, either take the laptop with you or ask your friends to keep an eye on it for you.

Be especially mindful of distractions! A commotion in front of you means that the thief about to take your laptop is behind you. A commotion behind you means the thief is in front of you. Thieves work in pairs or groups that way, using the commotion to distract you while they steal your stuff.
The old ball and chain

Your laptop probably comes with a hole or slot into which you can connect a security cable. That hole has an official name - the Universal Security Slot (or USS).

The USS is designed to be part of the laptop's case. A thief can't remove from the laptop any cable or security device that you thread through the USS; he or she can only cut (or unlock) the cable itself to free the laptop.

Obviously, the USS works best when you have the laptop in a stationery place. Like a bicycle lock, you have to park the laptop by something big and stable, then thread the cable through that big thing and the USS for the lock to work.

The best place to find a security cable for your laptop is in a computer or office supply store.

Some cables come with alarms. You can find alarms that sound when someone cuts the cable, plus alarms that sound when anyone moves the laptop.

Along with the development of the computer world, various brands of wireless keyboard and mice sets appear, you can purchase them from website or regular computer stores as well. Whatever your case may be, the directions for getting them ready for your computer are all basically the same. So, if you've bought a wireless set recently and you're having some trouble getting it to work, just follow these instructions and you'll be well on your way to wireless bliss!

First of all, wireless keyboards and mice aren't able to receive power from your computer like the wired ones do. Therefore, they need batteries to operate. And that's the first thing you need to do. Turn your keyboard over and you'll see a battery compartment. Take the cover off and insert the batteries according to the + - (plus, minus) compatibility. When you're done with the keyboard, you can go ahead and do the same thing for the mouse.

Once you've got the batteries in place, find a spot on your desk where you'd like to place both the keyboard and mouse. You won't have to move them around anymore, so make sure you find a place you'll be comfortable with. Now, while you're doing this, you'll also want to keep in mind where the wireless receiver will go. If you recall, a tip on that was in yesterday's newsletter.

The next thing you'll want to do is install the software that came along with your keyboard and mouse. Now, keep in mind that if you have Windows XP on your computer, you more than likely won't need to deal with the software at all. You can just plug the receiver into your computer and XP will automatically recognize the new hardware for you. On the other hand, if you're using an older version of Windows, you will need to install the software. To do so, just insert the disk into your CD ROM drive and follow along with the on-screen instructions. That's all you have to do!

The next step is connecting the wireless receiver to your computer, but again, if you have Windows XP, you've probably already done this. If not, it's likely that the wireless keyboard and mouse set you have works via a USB cable. So, all you have to do is find an open USB port on your computer and plug the receiver in. Once you plug it in, your computer will configure the keyboard and mouse so you can start to use them. You'll see a message that says something like "Your new hardware is now ready to use." (In XP, you'll get a pop up message that says "New Hardware Found"). Either way, that means you can now start using your new hardware!

Now that you've got everything set up, the next thing you'll want to do is test the keyboard and mouse, just to make sure everything's working properly. Go ahead and open some programs with your mouse and type some text in with your keyboard. Run through all the keys on your keyboard to make sure there are no problems with any of them and make sure all the buttons on your mouse work right.
Now, go on and enjoy your new wireless keyboard and mouse. Wireless really is the best way to go!

Having a good laptop battery is one of the most important parts of owning a laptop, especially if you intend to take advantage of the laptop's portability; without a good battery, your laptop will need to be plugged into the wall much more frequently, limiting your ability to take it with you. Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won't charge fully or stops holding its charge for as long; when this happens, you'll probably want to buy a replacement battery.

There are many laptop battery manufacturers, and even more retailers to buy your laptop battery from. However, your biggest concern in purchasing a laptop battery will be to choose the battery that fits your computer. For this you will need to know the make and model number of your laptop; if you don't know this offhand or don't have the necessary paperwork, check the inside of your laptop's battery compartment while the computer is off and unplugged. There you should find the model number, along with some other information. You may also find the part number of your laptop battery, located on the casing of the battery itself.

When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.

The nickel cadmium battery, known as NiCad (pronounced "Nigh-Kad"), used to be the most common type of laptop battery. Nickel cadmium batteries couldn't hold very much power by today's standards, and could only be charged a limited number of times. NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the "memory effect," meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it.

The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect -- although it wasn't as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn't have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.

Regardless of which type you have, it's important to properly care for your laptop battery, in order to get as much life out of it as possible. "Conditioning," which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery. Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it's a good idea to condition all laptop batteries regularly, rather than simply leaving them plugged into the wall at all times. Your laptop battery should never be stored in an area that drops below 50ºF (10ºC) or rises above 95ºF (35ºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled. Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.

Have you made the switch from a desktop PC to a laptop? Several people have and although they may be easier to carry around and travel with, they still need to be cleaned, don't they?

Laptops aren't as easy to open up and clean as desktops are, but it still can be done. To get started, just make sure your computer is turned off and unplugged. You should also remove the laptop battery just for some extra safety.

Laptop Case

Now, we're going to start with cleaning the outer case of your laptop so you can keep it looking new and fresh. Use a damp cotton cloth to clean the exterior of the laptop. It is recommended that you just use water, but if there is something on the case that cannot be cleaned with water, it is suitable to use rubbing alcohol. Do not use any household cleaners though.

Case Openings

Debris such as dirt, dust and hair can get into the case openings of the laptop and make it hard for the air it needs to pass through. This can cause the heat of the laptop to increase, which can cause later problems like random reboots. We definitely want to combat all of that, don't we? So, look for any of the openings that help cool air come in through the laptop and let hot air out. These are usually located on the back, the sides or even on the bottom of the laptop. The easiest way to clean these out is to use a cotton swab or compressed air.

If you use compressed air, you want to be careful that you don't spray directly at the fans that may be in the openings. It's easy to cause them to over spin, which can cause permanent damage. Before you use the air, place something in between the fan blades, such as a toothpick.

Laptop Keyboard

The keys on a laptop keyboard are different from a standard keyboard and they usually cannot be removed. So, to clean this, use the same damp cotton cloth you used to clean the exterior of your laptop. Just wipe the cloth over the keys and some of the dust and dirt particles will be removed. You can also use compressed air to get some of the debris out from in and around the keys.

Laptop Touchpad (Mouse)

It's a very good idea to clean your laptop's touchpad every once in awhile. It can help your laptop to look new, as well as, improve the quality of the motion and response of the touchpad. You can use the same damp cloth to clean this one too. Just run the cloth over the touchpad area and make sure you squeeze in around the corners to catch any debris that may be sitting there.

LCD Screen

Lots of things can fog up your laptop screen (like dirt, dust, fingerprints, etc.) and it's such a good idea to clean all of that off so your screen doesn't look like it just went through a whirlwind of yuckiness! An LCD screen is not like a regular desktop monitor, so it requires some special cleaning.

First of all, do not spray any liquids directly onto the screen. Doing this may cause some distortions on your screen. Also, do not use a paper towel to clean off the screen, because that could cause some scratching. Instead, use a soft cotton cloth. Try using a dry one at first and if that doesn't get everything off, you can put a little rubbing alcohol on the cloth and remove any other smudges that remain. Rubbing alcohol is used to clean the LCD screens before they leave the factory and shipped out, so it is safe to use.

Internal Components

This isn't the easiest task to perform, but with all of the debris that can get caught inside, it's important to do. If too much builds up, it can prohibit your laptop from running properly and smoothly.

I know this may have been the part you've been waiting on, but unfortunately, all laptops are very different and it's difficult to know what each one would need for cleaning. The best thing to do if you think your laptop needs special cleaning care is to take it to a repair center. They are professionals and they will be able to tell you exactly what would need to be done. It would be nice if we could do this step on our own, but with all the money you spend on your laptop and with all of the special uses you have for it, it's best to maintain that by letting a professional help you clean the inside components. You wouldn't want to mess anything up internally and permanently.

When traveling with a computer, protect it from shock, heat, moisture, radiation, and theft. Special hard-shell shipping cases are advertised for most Apple products. These cases can protect computer products from environmental abuse. In addition, they often do not look like computer cases, and usually escape the notice of thieves.

X-rays and other magnetic radiation associated with X-ray machines only pose a slight potential danger. Most airports X-ray all luggage. If the risk in losing software or data is too high, back the files stored on your computer's hard disk.

Due to concern about computers and floppy disks going through security scanners at airports, the American Society for Testing and Materials (ASTM) conducted a study on X-ray induced damage to memory devices, including audio and video tapes and floppy disks. They found that the devices usually have enough shielding to protect the media. The study found that the magnetic field was actually strongest around the scanner's monitor. They taped a disk to the monitor for several hours without damage. A committee member suggested that it would take at least 1000 million passes through the machine before any damage would be evident.
