Replace LED Bulb in a Compaq Presario F500

type="html">

The LED screen in your Compaq Presario laptop is powered by a bulb that is located directly behind the screen. If your screen is dark or is generally not functioning properly, it is likely the result of a blown backlight bulb. The good news is that you don't need to pay a computer tech to fix the problem for you, as you can replace the backlight yourself.

1). Power off your F500 and unplug the AC adapter power cable.

2). Slide the rectangular battery out of its compartment located on the underside of the computer.

3). Open the display screen and use your Phillips screwdriver to remove all screws on the sides and corners of the plastic frame that surrounds the display screen.

4). Use your fingers to pry the frame off of the screen at the sides and corners.

5). Locate the rectangular inverter board mounted directly below the screen. There will be two wires plugged into ports on either side of the board. The wire on the right side of the board is the backlight bulb wire. Unplug it.

6). Tilt the screen forward to expose the backlight bulb secured to the rear of the LCD with tape. Remove the tape covering the backlight bulb and remove the bulb.

7). Fit a new bulb in the old one's place and replace the tape.

8). Plug the bulb cable into the port on the inverter board and replace the screen frame and screws.

Membrane Keypads Tutorial

type="html">

 Unlike traditional keypads with moving keys, membrane keypads are pressure sensitive, with key outlines or symbols printed on a flat waterproof surface. A wide variety of products employ membrane keypads, such as remote controls and microwave ovens, printers and switches.

Industrial Uses

Membrane keypads are a part of many consumer products, but you can also find them in industries where hygiene is important or where systems are exposed to extreme environments. For example, medical technology, the automotive industry and the disposal and recycling industry use membrane keypads.

Membrane Layers

Membrane keypads consist of four layers. The contact elements for membrane keyboards are embedded between three layers of membrane beneath the waterproof outer layer. The bottom layer is printed with a conductive switch trace for each key. The middle layer, or spacer, has holes exposing each underlying switch. The top layer is a conductive layer with an optional array of rubber domes.

Keypad Action

Pressing keys on the outer layer of the membrane keypad completes a circuit. The keys force the conductive layer through the middle spacer so they contact the switch traces on the bottom layer. If rubber domes exist on the top membrane layer, they force pressed keys back into position when released.

Upgrade Power Supplies in Computers

type="html">

 

Power supplies are needed because your computer needs different voltages than what comes straight from the outlet. Disconnecting and replacing a power supply is simple because it's just piece of hardware.

1). Shut down your computer and unplug the cable from the wall and the back of your computer. Open the computer case. This may involve unscrewing the access door from the back of the computer, pushing a lever or just sliding the door off.

2). Unplug the power connectors from all of the drives and the motherboard. The connectors can be removed by either pulling them straight out or by pushing a release button first and then pulling the connector out. Some motherboards have two sockets where the power supply is plugged in.

3). Unscrew the power supply from the back of the case. The power supply is usually held in place by four Phillips screws. Pull the power supply out from inside the case. There is often a small shelf the power supply sits on. Hold on to the power supply as you unscrew it to make sure it doesn't fall.

4). Slide the new power supply into place. Screw it into the case from the back of the computer.

5). Connect all of the drives back to the power supply with the appropriate connectors. Connect the correct connectors to your motherboard as well. Make sure you plug the connectors back in the same direction they were plugged in as there is only one way in which they fit properly.

6). Close the computer case and plug the computer power cable into the power supply and the wall outlet.

Enable Power Management in the BIOS

type="html">

 

The BIOS controls the basic functioning of the various input/output devices connected or integrated within the system. Without the BIOS, the computer's main processor would not have the ability to communicate with or operate other pertinent components of the system. Enabling and adjusting the power management settings within the BIOS reduces power consumption and gives you control regarding how the computer operates when not in use.

1). Turn the computer on and enter the BIOS menu. Depending upon your particular computer or BIOS version, you have to press a certain key to gain access to the BIOS menu. Pay close attention to the display screen during the startup process, to determine the correct key. Alternately, consult your user manual or see Resources for a link of key combinations by manufacturer.

2). Enter the system password, if applicable.

3). Navigate to the appropriate power management options, using your keyboard. In most cases, highlighting a specific power management item produces an expanded explanation of the option.

4). Enable or adjust the appropriate power-management options, according to your needs. Save the settings and exit the BIOS menu. After saving and exiting the BIOS menu, the computer restarts.

What Does a Uninterruptible Power Supply Do

type="html">

An uninterruptible power supplies (UPS) serves as essential electrical backup to ensure that critical equipment stays running during power failures. When power is lost, the UPS automatically switches to its battery. Any electrical or electronic devices plugged into the UPS continue to work without a problem.

Voltage Monitor

Electronic circuits in the UPS continually monitor the power line's voltage. Normally, the alternating current (AC) power runs at 110 to 120 volts. If the voltage sags more than a few percent, for even a few thousandths of a second, the UPS switches over to battery power. The switching action is so fast that even sensitive equipment never registers a problem. When the AC line voltage returns to normal, the UPS switches the battery off, providing power straight from the outlet. The UPS uses the battery only when needed.

DC to AC Conversion

The electric power available at a standard outlet is alternating current, or AC. This electricity reverses direction at 60 cycles per second. Any appliance plugged into an outlet needs AC at the correct voltage. The UPS's battery produces direct current (DC) at a much lower voltage. An electronic circuit called an inverter converts the DC battery power to 120-volt AC that appliances can use.

Alarm

The UPS sounds an audible alarm when the power goes out, indicating that it's running on battery power. Depending on the size of the UPS and the devices running on it, the battery can last anywhere from 5 minutes to several hours. If you have a smaller UPS unit running a computer, for example, this gives you enough time to save your files and shut your computer down in an orderly fashion so you don't lose your work.

Surge Protection

In addition to battery backup, a UPS removes electrical surges from the power line from lightning and other causes. These spikes last millionths of a second but can damage sensitive electronic equipment such as computers. Your UPS may have separate sockets for surge protection. These sockets do not provide the advantage of battery backup, but will protect less-critical devices from power surges.

Battery Charger

During a power outage, the battery drains as the UPS uses its electricity. When the utility restores the power, the UPS automatically recharges the battery. If several outages take place within a short time, the UPS may exhaust the battery and shut down. But as long as power stays on for an extended period, the UPS will fully recharge the battery.

Connect LCD TV to Computer

type="html">

Flat-screen LCD televisions are designed to accept numerous inputs. Depending on the model of the LCD television, it may accept the older analog RCA video connections, analog component video, analog VGA, digital DVI and digital HDMI. Most LCD TVs accept multiple HDMI connections. Computers typically have analog VGA connectors, and quite often, they have digital DVI connectors. Increasingly, computers are coming equipped with digital HDMI connectors that carry video and sound over a single cable, which is perfect for connecting to an LCD TV.

1). Examine the back of your computer and determine which outputs are available. Choices in order of preference are HDMI, DVI and VGA.

2). Determine which inputs are available on the LCD TV.

3). Connect one end of the appropriate HDMI, DVI or VGA cable to the computer and connect the other end to the input on the LCD TV.

4). Connect a sound cable between the computer and the LCD TV, if any type of connection other than HDMI is being used. The computer side always requires a 3.5 mm headphone style plug. The LCD TV may also accept a 3.5 mm headphone plug or it may require RCA inputs for the audio. Either way, audio cables are available to suit your specific need.

5). Tune the LCD TV to the correct input. For example, if the second HDMI connection is being used, switch the TV to the HDMI-2 input.

6). Boot the computer and adjust the screen resolution appropriate for the TV. LCDs that support 720p have a screen resolution of 1280 x 720. LCDs that support full HD resolution use 1920 x 1080.

Clean the Rollers on a Phaser 6120

type="html">

The Xerox Phaser 6120 uses laser printing technology to transfer digital images and text to paper, creating hard copies. In order to create the printouts, the Phaser 6120 uses a series of rollers to move the paper through the inside of the machine. The toner powder, or the ink used in the Phaser 6120, as well as paper dust can eventually build up on the rollers with continued use of the printer. You may notice more paper jams or even black or grey streaks on the paper as a result. Cleaning the rollers takes a few moments of your time.

Ways to Save Printer Ink

type="html">

When you purchase a printer for your computer, the price you pay for the device itself is only a fraction of the cost you incur over the life of the device. From time to time, you must replace your printer's ink cartridges. Lessen your ink consumption by developing wise printing habits.

Print Quality

Most printers have the option of printing documents and pictures at various quality levels -- and the lower the print quality, the less ink the printer uses. Except for "final draft" items you need to turn in to a supervisor or instructor at work or school, get into the habit of printing documents at low quality to save on ink.

Page Count

When you print a document, your computer will prompt you to enter the pages of the document you want to print. Look through your document before printing to verify that you need all its pages -- and if you don't, adjust the page range to reflect what you do need. If you print a receipt from a website, for example, the entire document may take up four pages, even though your receipt itself appears entirely within the second page.

Color vs. Black and White

On the whole, color cartridges are more expensive than black and white ones -- and, since color documents print using a combination of ink hues -- these cartridges run out faster with regular use. Even if a document appears in color on your screen, your computer gives you the option to print it in black and white. Unless printing in color is essential to the purpose for which you use your document.

Mobile Documents

With the advent of "smartphone" devices such as the Android, BlackBerry and iPhone, the necessity to print out certain documents at all has lessened. From receipts to emails to -- in some instances -- airline boarding passes, it's possible to pull up full-length documents using the email or Internet feature on your handheld device. This saves not only on ink, but also on paper.

VESA Specifications

type="html">

VESA, short for Video Electronics Standards Association, is an international organization founded in 1989 that established industry wide standards for uniformity in the video electronics market. VESA wall mounts have become especially important for mounting flat-panel plasma televisions and LCD monitors. The standards provide equipment manufacturers with specific guidelines of mounting-hole pattern placement and screw size in three different designs which are based on the monitor's weight and size of the screen.

VESA MIS-D

The VESA MIS-D is the standard design for small- and medium-sized flat panels, LCD monitors and screens. The design accommodates screens that range in size from 12 to 22.9 inches diagonally with a maximum weight of 30.8 pounds. The four-hole screw pattern ranges in size from 2.95-by-2.95 inches to 3.94-by-3.94 inches.

VESA MIS-E

The VESA MIS-E standard design is for larger LCD monitors, flat panels and screens with a maximum weight of up to 50 pounds. It can accommodate screen sizes between 23 and 30.9 inches diagonally and includes two six-hole screw patterns: 7.87-by-3.94 inches, and 7.87-by-7.87 inches.

What Is a VESA Wall Mount?

type="html">

VESA, the Video Electronics Standard Association, is an international body that sets standards for computer graphics. VESA standards also relate to display devices, and the safe and proper attachment, or mounting, of such devices.

Definition

A VESA wall mount, also referred to as FDMI, or Flat Display Mounting Interface, is a device that screws or otherwise attaches to a wall and supports display devices such as plasma televisions and other flat-panel monitors. Manufacturers that produce VESA wall mounts must meet certain variant standards to be VESA compliant.

Variants

The MIS-D, or original VESAmount, includes a panel that must contain four screws in a square arrangement. These screws require a vertical and horizontal distance between them of 100 mm. MIS-D screws use an M4 thread, or ridge that wraps around the screw to form a helix shape. M4 refers to a 4-mm diameter screw head. MIS-D screw holes are 10 mm deep; 10 mm fasteners are typically included with the VESA mount. Another VESA mount variant is the MIS-D 75, which has a 75-mm layout.

Identification

Manufacturers of VESA-compliant devices can display a label verifying that they meet the appropriate standards, called the "VESA mounting compliant" logo.
