Computer Mouse and Keyboard Tips

Four Reasons to buy an Optical Mouse

Are you still using an old ball mouse to navigate your way through Windows Explorer or the Internet? Ball mice are old-fashioned and outdated! Keep in style and buy yourself an optical mouse. Everyone already has one these days.
If you do not happen to have one already, here are some great reasons to buy an optical mouse.
* Low Maintenance
An optical computer mouse no longer relies on balls to detect a cursor’s location on the computer monitor. The optical mouse emits a light emitting diode (LED) — usually colored red — that detects the device’ movements. When in movement, the optical mouse takes thousands of pictures of the flat surface on which it is placed. By measuring and comparing the small and minute distances the mouse travels when you move it about a flat surface, the optical mouse is able to tell how far to move your onscreen cursor.
Since it no longer uses a ball, the optical mouse is easier to maintain. You no longer need to clean up any balls when they get dirty. In addition, you can enjoy the benefits of smoother and continuous cursor movements. When the balls of mechanical mice get clogged with dirt and dust — and this happens often — cursor movement becomes irritatingly choppy.

* No More Mouse Pads
Optical mice can be used on any flat surface such as the top of your computer desk, a book or a bench. As such, they obviate the need for mouse pads. Ball mice, on the other hand, rely on mouse pads to detect and translate movement.
Make sure, however, that you place your optical mouse on an opaque surface. If you place it on top of a transparent surface, some of the LED will seep through the transparent surface. Consequently, your optical mouse will not be able to accurately record and process movements.

* Lightweight
Optical mice are lighter than ball mice. This makes them easier to maneuver. For those who work long hours in front of their computers, you will appreciate the lightweight build of an optical mouse. With an optical mouse, you will encounter less friction and resistance when moving your mouse about, and minimize hand and wrist strains.

* Eye-catching
One attribute that makes optical mice so appealing is their eye-catching colors and designs. The LED lights of optical mice alone are a treat. Usually sporting red LEDs, more modern optical mice can have green and blue LEDs. Others optical mice have transparent casings so their glow is evident in dimly lit areas. Some optical mice even cycle through many colors.
For appeal alone, an optical mouse is a great addition to your computer accessories!

Computer Desktop Tips

Four Types of Desktop Computers According to Architecture

Size and mobility are always an issue with desktop computers. These bulky PCs will always occupy a fair amount of space on your desk — which is why they are called desktops. There are, however, desktop computers that are smaller than others. Each has its pros and cons. According to architecture, desktop computers may be classified into four general types: small form factor computers, all-in-one computers, standard mid-sized computers, and tower computers.

* Small Form Factor (SFF) Computers
Small form factor computers are very portable desktops that range between a third and one-half the size of normal computer cases. Because of their small size, they can only accommodate a limited number of components. If you are contemplating on getting a small form factor, carefully consider which components you want to have. You may not be able to fit everything you want inside the small casing. The connectivity options of SFFs are also limited due to their size.
Most small form factors are barebone PCs that include a built-in motherboard, graphics card, and sound card. You can still attach a separate graphics card or sound card to your SFF at the cost of space.

* All-in-One Computers
Unlike the other computer types which need to be connected to an external monitor, all-in-one computers include an integrated LCD monitor. As such, these computers look like flat-screen televisions. The computer components are crammed and hidden behind the LCD screen. Because of limited space, all-in-one computer owners, like small form factor computer owners, have few upgrade and connectivity options. There are only so many components that can fit in a small box.
All-in-one computers are real space savers. Because you no longer need to connect your computer to an external monitor, you can clear up more space on your computer table and keep your desk neat and clutter-free.
* Standard Mid-Sized Computers
Standard computers are the most popular type of desktop computers at the moment. They are the regular-sized computers that you see everyday. Because space is not an issue, standard computers do not need any high-priced special components like SFFs and all-in-ones. Standard computer owners have a lot of room on which hardware to use and how many.

* Tower PCs
Tower PCs are designed for multimedia professionals and hardcore PC gamers. They are larger than regular PCs and can therefore accommodate a lot of extra hardware. Depending on your motherboard, you can plug in two graphics card, a separate sound card, a number of optical drives, and an equal number of hard disk drives into your tower PC. With a lot of hardware plugged in, tower PCs make very powerful machines.
Aside from their fast performance, tower PCs also minimize overheating issues. Because of their large size, more air can circulate within the casing. Many 3D gamers will even install fans to help keep components cool.
When scouting for a desktop PC, define your priorities. Do you want added mobility at the cost of performance, or more power but a bulky PC? If you are on a budget, a regular-sized PC is the best desktop to purchase.

Computer Desktop Tips

Four Reasons to Choose a Desktop Over a Laptop

Desktops are those bulky and heavy computers that occupy a lot of space on your desk. Laptops, on the other hand, are sleek rectangular boxes that you can bring with you wherever you go. Some people prefer using a desktop PC while some are happier with a laptop computer. Here are some reasons why it is better to get a desktop instead of a laptop.

* Cost
Regular desktop computers do no need specially-designed mini components that can be crammed into a small area. Thus, they are generally more affordable than a laptop with similar features. Portability accounts for a big chunk of a laptop’s selling price. If you have a small budget and no reason to tout your computer about, a desktop computer is a cost-effective solution for you.

* Power and Upgradeability
Many laptops have built-in components that cannot be replaced by newer and faster hardware with a different architecture. If laptop components wear down, they can only be replaced by the same components. A desktop, however, offers more room for upgrades and modifications. Depending on the size of your casing, you can experiment with various motherboards, processors, video cards, hard disk drives, and other computer hardware. Equipped with more computer components, a desktop will be capable of processing more applications than a laptop computer. If you are looking for a top performing workstation that can run the latest 3D games at high frame rates, you will want to get a desktop computer.

* Durability
Because they are often transported about, notebook computers experience more wear and tear than desktop computers. Laptop components such as screen hinges and power cords eventually wear out with gradual use. A liquid spill on the keyboard, which is a minor incident on a desktop system, can be quite disastrous for a laptop unit.
Laptops are also more prone to overheating problems than desktop computers. Because of their very small sizes, it is difficult for air to circulate and cool laptop components. Dust filtering in from outside can clog a laptop’s cooling system and render it inefficient over the years. Desktop computers parts generally have more room to breathe in and, thus, cool off faster and last longer than laptop components.

* No Battery Worries
Desktops are directly connected to a power outlet, thus, you do not have to worry that they will die out on you — unless if there is a power outage. The scenario is different for laptops. Laptop computers usually run on batteries and these batteries can only last for a couple of hours. When working on a laptop that is not directly connected to an electrical outlet, you need to keep a watchful eye over your battery levels.
If you are working with a small budget, you can get more bang for your buck with a desktop computer. You not only spend less but end up with a sturdy and powerful system that can run continuously for hours on end

Computer Desktop Tips

Three Reasons to Buy a Tower PC

People place a lot of importance on a computer’s portability. Laptops are prized for their small size and light weights. But smaller is not always better. Most of the time, you will find yourself paying a hefty premium for a very portable laptop that is not as powerful as its desktop counterpart. If you do not feel the need to bring your computer with you every time you go out, a laptop will not be a cost-effective purchase for you to make. Why not consider buying a large desktop computer — the tower PC — instead? Tower PCs make a fine centerpiece on any study table.
Here are some great reasons why it is better to get a tower PC instead of a regular-sized desktop computer or a laptop.

* More Space
One obvious advantage of a tower PC is its roomy interior. With a tower PC, you can install a lot of hardware inside your computer and still have room to spare for a couple more components. Depending on your motherboard, you can fit two or four video cards, two or more hard disks, a sound card, two or more optical drives, and a number of fans inside your computer case.

* More Power
With more hardware, you will have a faster and extremely powerful PC. This is especially useful for avid PC gamers and professional designers. With at least two dedicated graphics cards, multimedia applications will run smoother and faster, and you enable you to view graphics at higher resolutions. With two CD writers, you can copy files between CDs without transferring the CD files into your hard drive. With more hard disks, you can store more information and back up all of your files.

* Efficient Cooling
The tower PC also gives your computer components more room to breathe in than in the cramped quarters of a small form factor computer or a laptop. With more space, air can better circulate in between computer components and hasten the cooling process of sensitive hardware such as the CPU and video cards. Cooling is hastened all the more if you add more fans which help usher in cool air from the outside and guide hot air outside the computer case’s vents.
With a tower PC, you can enjoy all of these advantages and more! You may not have a mobile machine, but you will have a computer that is more powerful and cool.
Desktop Coupter Case Information
Size – desktop and mini-towers are very attractive but these types have limited room for expansion when you want to upgrade or add some other internal hardware. The midsize and full towers are the better choices.
Number of drive bays or expansion bays – this is where you install your hard drives, DVD-roms, CD-roms, etc… The minimum is usual three drive bays but when you go for the full tower casing, you can have as many as seven or more drive bays.
Design – it should have an aerodynamic design that provides good airflow, and the casing should be strong to ensure that the components inside are sufficiently protected and secured.
Power supply – choose the 300 watts to get your motherboard, processor and other components boosted.

Computer Maintenance Tips

Computer Maintenance Tips

Laptop computers are bombarded with plenty of dust and dirt if you take them out with you often. Dirt and grime love to accumulate around and in between your laptop keyboard keys. If you want your laptop to be free from dust and germs, you need to clean the keyboard.
Before you attempt to clean your keyboard, make sure that your laptop is turned off and unplugged to avoid electrical shocks which can easily fry your laptop’s internal components. In addition, remove all your laptop accessories and peripherals, including any removable media devices.
On some laptops, it is easy to remove the keys and replace them. On others, this may not be so simple. If you are not sure whether you should remove your laptop keyboard keys, it is better to leave them alone. You can check your laptop manual for keyboard cleaning instructions.
If you decide to leave your laptop keyboard intact, you can still effectively clean it. You can begin by tilting your laptop and directing a can of compressed air against the keys. You can already dislodge a lot of foreign particles in this manner. For tough dirt and grime, you can use cotton swabs slightly moistened with isopropyl alcohol.
If you remove the keyboard keys, you can do a more thorough cleaning. Take note of the key orientation before you take out each key so you know how to reassemble the keyboard. Using a screwdriver or small knife, you can gently pop off the keyboard keys. The space bar and other large keys like the ‘enter’ and ’shift’ buttons are usually difficult to remove so it is better to leave them in place.
Set aside the removed keys and hand wash them. You can wipe the exposed keyboard clean by using a soft cloth. You can also use a mild cleaning solution — Just make sure that you apply it sparingly on your cleaning cloth and not directly on the keyboard.
Once everything is squeaky clean, allow the keyboard and keys to dry completely before reuniting them. Do not close the lid while your keyboard is drying.
You now have a clean laptop keyboard!

How to Clean Your Desktop Computer Keyboard

Desktop computer keyboards easily get dirty especially if many people share the same workstation. It is a good thing that cleaning a computer keyboard is a pretty straightforward task. There are two ways that you can take when cleaning your computer keyboard: You can do a light cleaning or you can do a major cleaning.
For a light cleaning, you can simply turn your keyboard upside down and gently whack it against your legs. Make sure the keyboard is disconnected from your computer when you do this. You will be surprised at the amount of foreign material that can be dislodged in this manner. To further aid in loosening foreign objects, use a can of compressed air.
You can scrub away dirt and grime stuck on keyboard keys by using a cotton swab moistened with water or isopropyl alcohol.
For a complete and thorough cleaning, you can pry off your keyboard keys using a screwdriver or other lever. Do not forget to note the position and arrangement of the keys when you do this! You can take a picture of your keyboard so you can remember where to pop back each key once you finish cleaning.
Do not force out any key if it is difficult to remove. If you have difficulty prying out the space bar, you may as well just leave it be. The space bar is generally difficult to replace and prone to breaking due to its long length.
After you remove all of the keyboard keys, use compressed air to clear out debris within the keyboard frame. Using a moist cloth, gently wipe away any remaining dirt and dust. Make sure your cleaning cloth is only damp and not wet.
After dealing with the keyboard frame, you need to clean and wipe each key individually. This makes for a tedious and very boring task. If you are feeling lazy, you can place the keys in a net bag and wash them in the washing machine.
After everything is clean and dry, reassemble your keyboard, plug it back in your computer, and resume working!

Computer Maintenance Tips

Three Simple Computer Maintenance Tips

Caring for your computer is an essential task if you want a machine free from errors. A well-maintained computer can service you for a long time with few problems, if any. Here are three simple things that you can do to keep your computer healthy and fit.

* Clean Your Computer
Clean your computer not just on the outside, but also on the inside. Dust and dirt can coat your computer components and cause them to overheat. They can also weigh down the blades of your computer’s internal fans and hamper the flow of air within the system, which aggravates overheating issues.
When you dust off your computer, do not forget your internal components. You can easily blow away dust and debris from inside your computer case by using a can of compressed air or a small hand-held vacuum cleaner.

* Organize Your Hard Disk Drive
Boost your computer’s performance by organizing the files on your hard disk drive and performing hard drive checks. You can do this by deleting data that you no longer need and running Window’s disk cleanup and disk defragmenter utility tools. It is advisable to defragment and check your hard drive for errors once a month.

* Back Up Your Data
Backing up your data is an integral part of computer maintenance. This is doubly important for corporate workstations and the personal computers of professionals who bring their work home. In the rare event that your computer bogs down, you will still have access to important files, especially your work files. You can back up your computer files by copying them to any of the many media for file storage available today such as external hard drives, CDs and DVDs, and USB flash drives.
There are many more things that you can do to keep your computer in tip-top condition! Take good care of your computer and it will reward you with smoother operations and a longer lifespan
