Surge Protectors Protect Against Power Surges

The surge protector is an important, yet often overlooked part of a computer setup. It allows multiple devices to plugged in to it at one time and protects each connected device from power surges. For example, a home office may have a computer, monitor, printer, cable modem, and powered speakers all plugged into one surge protector, which is plugged into a single outlet in the wall. The surge protector allows many devices to use one outlet, while protecting each of them from electrical surges. Surge protectors, sometimes called power strips, prevent surges in electrical current by sending the excess current to the grounding wire (which is the round part of the plug below the two flat metal pieces on U.S. outlet plugs). If the surge is extra high, such as from a lightning strike, a fuse in the surge protector will blow and the current will prevented from reaching any of the devices plugged into the surge protector. This means the noble surge protector will have given its life for the rest of the equipment, since the fuse is destroyed in the process. While surge protectors all perform the same basic function, they come in many shapes and sizes with different levels of protection. Some may look like basic power strips, while others may be rack mounted or fit directly against the wall. Most surge protectors offer six to ten different outlets. Cheaper surge protectors offer limited protection for surges (under 1000 joules), while more expensive ones offer protection for several thousand joules and include a monetary guarantee on connected devices if a power surge happens. Typically, you get what you pay for, so if you have an expensive computer system, it is wise to buy a quality surge protector that offers at least 1000 joules of protection. Some surge protectors also include line conditioning, which uses an electromagnet to maintain a consistent level of electricity when there are slight variations in current. For example, you might notice your computer monitor or television fade for a moment when you turn on a high-powered device, like a vacuum or air conditioner. A surge protector with line conditioning should prevent connected devices from being affected by these slight variances in current. While you may be able to hook up your computer system without a surge protector, it is important to protect your equipment by using one. You may not need a large, expensive surge protector with line conditioning, but using a quality surge protector for all your electronic devices is a smart choice.

The LCD Inverter

An LCD (liquid-crystal display) inverter is a component in laptop computers that supplies the power to provide a backlight to the monitor, enabling the user to view what's on the screen. The main purpose of the inverter is basically to give power to the backlight. The way it works is simple, it takes power from the laptop itself by a small inverter lead that runs from the motherboard of the laptop, sometimes it is a direct lead on it’s own, other times this lead can be connected into the inverter through the LCD cable (the lead that runs from the motherboard to the back of the screen itself), giving the screen its visual display. LCD Inverters are also used in other devices that have LCD screens, including standard- and high-definition television sets and desktop computer monitors.

Even though a screen inverter performs a seemingly simple task in laptop computers, it can also be one of the most common to fail. This component is commonly the culprit when the monitor goes out and the most common problems related to lack of display and more specifically, dark or the darkness on the screen itself that can be moderately simple to replace. When an LCD inverter is going bad and needs to be replaced, the light to the monitor can either go out altogether, go out after a brief period of usage, or flicker on and off; the much dimmer image can sometimes still be seen on the screen. You can replace it without taking it to a professional, to access it for replacement or repair, unscrew the panel around the screen and carefully remove it but larger problems could be caused if it's not done correctly.

When it comes to purchasing an inverter most companies will require the part number which is usually printed on a bar code on the outside of the inverter but sometimes you may need to look carefully to find it. The LCD Inverter is generally located inside the cover assembly behind the front screen panel near the LCD itself. If your lucky then you may get away with just stating what your laptop make and model is we try our hardest to locate the inverter with just these details, however sometimes you will need to provide the part number.

Computer Adapters We Use Everyday

Computer adapter is a device which converts incompatible signal or a connector to a compatible or usable form. We use adapters everyday, knowingly or unknowingly. For instance, you charge your mobile devices using a charger which is basically a power adapter. If you directly connect your device to the electric plug, you will end up frying it. The adapter used here is a power adapter. There are several other kinds of adapters like USB adapters, network adapters, video or audio adapters, connectors and many others. USB adapters are those which you use to connect your mobile to your PC. Network adapters or Ethernet adapters are simply routers and switches. Video adapters or multimedia adapters include TV Tuner cards and Video cards which process graphic data. Audio adapters are sound cards and connectors are those which connect two different devices. Despite not containing any electronic circuitry, connectors are sometimes referred to as adapters because of their behavior.

Multiple Original Printer MOPIER

Mopier ( Multiple Original Printer), from the word itself it is a machine that prints out multiple documents and images faster and simultaneously. It’s also frequently associated with Multifunctional Printer (MFP). They are the latest innovations from the leading manufacturers, in which through their intensive and careful studies, analysis and surveys, they are able to come up with the state of the art equipment that captures their market beyond their expectations. Hewlett Packard released its latest LaserJet Pro M275. It’s not just an ordinary MFP but it’s has an additional features that make it able to scan high resolution 3D objects which is mostly in-demand for the film making market. It’s Hewlett Packard’s “TopShot”

Cleaning CPU Fans

People ask how often do we need to clean our computers – as often as possible. One of the least given priority is the CPU fan. Normally, if the CPU fan is unclean or not maintained, it tends to be noisy. It’s either dusty or it lacks oil to spin properly.

To get started, unscrew the CPU fan and pull it out from the computer. Hold it properly, keeping away your fingers from the blade. Spray it with short bursts of air. You may also use an old toothbrush or a sift paint brush to clean the blade and inner part of the fan. Make sure you hold it with your fingers and not to let it spin fast or you’ll get cut.

To fix the fan, use a pointed tool to remove the sticker at the back of the fan. Pour a small amount of WD-40 (lubricant) on the hole to lubricate the bearing. Let it settle. Place the cap back. Give the fan a few spin to have the grease going through the whole bearing. Give it more spin. If you see the fan spinning smoothly, then it is already in good shape and ready to use. Screw it back again in your CPU for use.
