Diagnostics

Dell??? Vostro??? 1220 Service Manual

Device Status LEDs

Device status LEDs are a good source for diagnosing common problems that may occur on your computer.

Turns on when you turn on the computer and blinks when the computer is in a power management mode.

Turns on when the computer reads or writes data.

Turns on steadily or blinks to indicate battery charge status.

Turns on when wireless networking is enabled.

Turns on when a card with Bluetooth?? wireless technology is enabled. To turn off only the Bluetooth wireless technology function, right-click the icon in the system tray and select Disable Bluetooth Radio.

Battery Status

If the computer is connected to an electrical outlet, the battery light operates as follows:

???Alternately blinking amber light and blue light ??? An unauthenticated or unsupported, non-Dell AC adapter is attached to your computer.

???Alternately blinking amber light with steady blue light ??? Temporary battery failure with AC adapter present.

???Constantly blinking amber light ??? Fatal battery failure with AC adapter present.

???Light off ??? Battery in full charge mode with AC adapter present.

???Blue light on ??? Battery in charge mode with AC adapter present.

Battery Charge and Health

To check the battery charge, press and release the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For example, if four lights are on, the battery has 80 percent of its charge remaining. If no lights appear, the battery has no charge.

To check the battery health using the charge gauge, press and hold the status button on the battery charge gauge for at least three seconds. If no lights appear, the battery is in good condition and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery.

Keyboard Status LEDs

The green lights located above the keyboard indicate the following:

Turns on when the numeric keypad is enabled.

Turns on when the Caps Lock function is enabled.

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your personal safety. Unless otherwise noted, each procedure included in this document assumes that the following conditions exist:

???You have performed the steps provided below.

???You have read the safety information that shipped with your computer.

???A component can be replaced or--if purchased separately--installed by performing the removal procedure in reverse order.

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface, such as a connector on the back of the computer.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTE: The color of your computer and certain components may appear differently than shown in this document.

To avoid damaging your computer, perform the following steps before you begin working inside the computer.

1.Ensure that your work surface is flat and clean to prevent the computer cover from being scratched.

2.Turn off your computer (see Turning Off Your Computer).

3.If the computer is connected to a docking device (docked) such as the optional Media Base or Battery Slice, undock it.

CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.

4.Disconnect all network cables from the computer.

5.Disconnect your computer and all attached devices from their electrical outlets.

6.Close the display and turn the computer upside-down on a flat work surface.

CAUTION: To avoid damaging the system board, you must remove the main battery before you service the computer.

7.Remove the main battery (see Removing the Battery).

8.Turn the computer top-side up.

9.Open the display.

10.Press the power button to ground the system board.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the display.

CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal components.

11.Remove any installed ExpressCards or Smart Cards from the appropriate slots.

12.Remove the hard drive (see Removing the Hard Drive).

Recommended Tools
