is used to measure electrical resistance, direct current (DC) voltage, or alternating current (AC) voltage and Resistance (Ω).

CAUTION!

- Always check your selector switch before testing components & electrical sources. - Set to specific type of voltage range (AC or DC) and always set to a much higher voltage than

the actual voltage output. - Always check your positive (+) & negative (-) probe when testing DC voltage.

AC Voltage Test = no polarity ( AVR output, wall outlet, UPS output, power cable connected to wall outlet etc.)

DC Voltage Test = with polarity (laptop battery, CMOS battery, desktop power supply connector pins, AC adaptor connector etc.)

Continuity test = no polarity & not connected to circuit (power cable, switch, fuse, wire, speaker, power jack connector, transformer etc.)

Resistance test (Ω ohms) = with polarity ( diode, transistor, electrolytic capacitor etc.)

POWER CONNECTOR OF AN AC ADAPTOR

Voltage output measured near to voltage specs.

Not Commonly Used

means the AC Adapter is good. - No deflection means the wire is open (bad) - With deflection means the wire is good

X1

With deflection means the fuse is good No deflection means the fuse is bad (wire is open)

No deflection at all in any of the two contact terminal means the Power Jack is bad (Open)

With deflection in any one of the two contact terminal means the Power Jack is good

LOCK KEYS The keyboard has 3 lock keys w/c you can toggle on & off.

TOUCHPAD

The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimal comfort and support.

NOTE: If you are using an external USB mouse, you can press Fn-F7 to disable the touchpad.

Simple diagram that will help you to understand how a Laptop/Notebook display assembly works and how an image appears on the screen.

VIDEO CABLE

A video signal from the motherboard goes to the LCD screen through the video cable. The video cable connects to the motherboard (or video card) through the connector 1. The video cable connects to the LCD screen through the connector 2. The video cable (in most cases) is also responsible for supplying a necessary voltage for the FL inverter board. The video cable connects to the FL inverter board at the point 3.

FL INVERTER BOARD

This board is responsible for converting low voltage DC power (point 3) to high voltage AC (point 4), necessary to light up the backlight bulb.

CCFL (backlight bulb) – Cold Cathode Flourescent Lamp

When the backlight bulb lights up, you can see an images on the LCD screen.

LID CLOSE SWITCH

The lid close switch is a small button that locates close to the display hinges. On some newer models there is no button, because the switch is magnetic. You can set up your laptop to go to a hibernation mode or to a standby mode when the LCD is closed. It’s done through power management software. These modes are triggered when the display is closed and the lid close switch is pressed down.

Nonstandard form factors prevent internal upgrades.Installing a faster CPU of the same type and model is usually possible; however, there can be limitations due to voltage, thermal, and/or BIOS support issues, and clock speed increases will normally be small.Normally, only one or two SIMM/DIMM sockets are available. You may need to remove lower-capacity existing modules to upgrade.Video is integrated into a non-upgradeable motherboard.Nonstandard form factors and connections prevent internal upgrades.Nonstandard form factors and connections prevent internal upgrades.Older systems might not have BIOS support for drives larger than 8.4GB. Many systems are limited to 9.5mm- or 12.5mm-thick drives. Drive trays or caddies are often required for installation.

Install these internally via modular bays or use external USB or IEEE 1394 (FireWire/i.LINK) drives.

Install these via PC Card/CardBus or ExpressCard adapters.

Install this via a PC Card or CardBus adapters.

Install these via PC Card, CardBus, Mini PCI (internal) cards, or mobile daughter cards (MDCs). Internal cards may require preinstalled antennas.
