How to Clean a Laptop Properly

laptop

This is very important make sure that the cleaning solution does not contain any Ammonia as this may damage your screen and

So be sure to check the ingredients if you are using any household product like a glass cleaner. You will find most Computer shops stock specialised cleaners. Most of these cleaners are made up of approximately 50% distilled water and 50% rubbing alcohol or isopropyl so you could make the solution up yourself.

Before starting any cleaning ensure it is turned off and unplugged for obvious reasons. If the laptop has excessive dust/dirt then give it a quick blast with the compressed air, do not shake the can of compressed air. Use you small brush or cotton bud to clean the larger particles between the keys. Just to dislodge them and then use the compressed air once again. Next use a damp cloth for the surface dirt on the keys and panel. Any ports or buttons maybe cleaned using the brush or cotton buds then use the compressed air to remove the remaining dirt. If you would like to clean the fan on your laptop, some fans cannot be seen, use the cotton bud to hold the fan steady as you clean and use the compressed air. The reason for this is because the power of the air may make the fan spin faster than it was designed to, it could cause permanent damage. If your laptop has a floppy drive, CD ROM/DVD ROM drive or card port then open then up and use the compressed air to clean them out. Be careful not to touch the lens within the CD/DVD as this could damage it. When cleaning the screen apply the cleaning fluid to the cloth and not directly on to the screen itself. Use slow smooth continuous motion to avoid leaving streaks. Use as much of your hand as you can while cleaning the screen as small pointed objects even your fingers can damage it. The case is cleaned the same as the screen and when completed you will have a laptop that looks as good as new.

If you are experiencing problems reading from your CD's or DVD's then you should purchase a CD/DVD cleaning disk. These can be obtained from most Electrical and Computer stores.

I have heard of people using a plastic card like a credit card wrapped in a cloth to clean between the keys.

Caution

Do not use any solutions that contain Ammonia as it could damage the laptop.

Do not shake the can of compressed air. The can has liquid within it and this will create a vapour that is not good for your laptop. So keep the can upright when spraying. Make short bursts (1 second) in the area you wish to clean. Do this 2 or 3 times and rest the can for at least 20 seconds to allow the liquid to settle and then repeat if necessary.

Understanding How Drivers Work

Every computer has a number of peripherals and hardware components that give it the natural functionality we have come to expect. This includes a mouse, keyboard, modem, printer and motherboard, among other components. If these devices are not able to communicate with the underlying operating system, they will not function properly. Thankfully, device drivers are what enable this clear communication. For example, if you purchase a new piece of hardware, it comes included with an installation CD which contains a device driver that allows the hardware to “talk” with your computer. Why Device Drivers are Important Device drivers are small codes and files that form a bridge of communication between the hardware and operating system installed on a computer. For the most part, every piece of hardware you install requires a device driver so the system can see it and handle it accordingly. Windows operating systems usually come integrated with numerous device drivers that instantly recognize common desktop hardware components and provide immediate functionality for the end-user. The Types of Device Drivers There are many types of device drivers, some of which are specific to certain machines. For example, device drivers for laptop computers are proprietary and installed by the manufacturer upon being designed. A desktop is typically the exact opposite. If the hard drive on a laptop is reformatted or deleted for any reason, all the original drivers will remain intact. With a desktop computer, you are generally required to visit the websites of each individual manufacturer, download and reinstall the drivers along with another operating system. When Good Drivers Go Bad There may be instances when device drivers do not function as intended or have conflicts with other computers. You will find that manufacturers make improvements to device drivers similar to how software developers upgrade programs. In some cases, such upgrades can make older drivers obsolete. Likewise, an updated driver can heal a wide range of bugs and behavior problems endured by a particular device. For example, if your printer isn’t functioning properly, fixing the issue is often as simple as checking the manufacturer’s website and downloading the corresponding driver. How Device Driver Updates Work Device drivers download like any other program and typically act as self-installing files. Most of them download as exe. or executable files. In most cases, you simply need to click on the file and the installation program is launched. The program will usually scan the system first to ensure that the driver corresponds to the installed hardware component. A device driver can often be installed in a matter of seconds, but normally requires a system reboot in order to function properly with the corresponding hardware. The easiest way to check the status of device drivers on a Windows operating system is to access the Device Manager utility. Simply right-click the “My Computer” icon, select “Properties,” click on the “Hardware” tab, and then choose “Device Manager.” Once you are in the Device Manager window, highlight the hardware device you want to investigate and right-click it. In the new window, select “Properties” and click on the “Driver” tab. From here, you can view the name of the driver, the version number, as well as perform the necessary updates

UPS

Okay, so we have all heard and used the term in our daily lives. However, have you ever wondered what on earth UPS that sounds like a scarier, technical term actually mean? Well, a UPS essentially means Uninterrupted Power Supply and is the power back up used to keep your devices running in case of sudden power cuts. However, it is not just that. A UPS is an extremely useful device that is placed between the power supply plug and your computer to safeguard it from any sudden negative features of the power source.

The Uses of UPS

There are a number of power related problems that a UPS solves or tackles. It not just provides a power back up to your system in cases of power failure but also protects it from sudden voltage fluctuations, under or over voltage situations that sustain for a long time and causes over heating of various kinds, frequency variations and other such power related harmful behavior.

Some of the more advanced UPS also provide features like automatically shutting down system in case of longer periods of erratic power behavior and later restarting it when the conditions are normal, displaying the voltage or current that the equipment is drawing, ringing alarms on certain conditions and providing protection from short circuit.

In addition to the kind of protection that a UPS provides or in other words, its functions, it is also good to know where all a UPS unit is installed. For most of us, a UPS is directly associated with our computers. However, other than computers, a UPS unit is also used to protect data centers, telecommunication equipments or any other electrical equipment which has danger from uneven power supply features.

The right size of UPS

Which is the right size of UPS that you should go for is directly associated with the size of your equipment. UPS are available in watt categories ranging from units powerful enough only to sustain a single computer to megawatt units capable of backing up entire buildings or data centers. For how long your UPS will sustain your equipment in case of a power cut depends on the size of the unit.

Different UPS Technologies

There are three types of power back up devices which are generally referred to as types of UPS-the SPS, the Hybrid UPS and the real UPS. The SPS (Standby Power Supply) or offline UPS derives power from the main power switch and in case of a power cut runs on its batteries, the Hybrid UPS use a transformer that maintains a constant voltage output while the real UPS continuously operate from an inverter.

Depending on your needs or the kind of equipment in question you can choose your UPS. The Internet can be a useful tool in getting you closer to the UPS that suits you the best. You can do a comprehensive study of what is available online and then even order it through any e-shopping portal. These portals not only provide a detailed description of the features of the product but also sell them at some very good deals and interesting offers.
