Installing Add-In Cards

At some point, you may add an AGP or PCI card to the computer to accommodate a new component, such as a scanner, or to upgrade an existing card.

You need a #2 Phillips screwdriver and a medium flat-blade screwdriver. You also need any software (for example, drivers) supplied with the card.

Warning: Do not overload the system

by installing add-in cards that draw excessive current. The system is designed to provide 2 amps (average) of +5 V power for each board/card in the computer. The total +5 V current draw in a fully loaded system (one with all add-in card slots filled) must not exceed the total number of slots multiplied by 2 amps.

Avertissement : Ne surchargez pas

l’ordinateur en installant des cartes d’extension qui consomment beaucoup de courant. L’ordinateur est conçu pour fournir un courant de 2 ampères (en moyenne), +5 volts, à chaque carte installée sur l’ordinateur. La consommation totale de courant de +5 V sur un ordinateur entièrement chargé (dont tous les logements de cartes sont occupés) ne doit pas excéder le nombre total de supports multiplié par 2 ampères.

To add or replace an add-in card:

1 Turn off the computer and all peripherals. 2 Disconnect the modem/phone cable. 3 Disconnect the power cord and all other

attached cables (such as the keyboard, mouse, and monitor).

4 Remove the side panel (see “Removing the

Side Panel” on page 7).

Warning: Be careful of the sharp edges

on the expansion slot cover.

Avertissement : Soyez prudent, car les

bords du couvercle du logement d’extension sont tranchants.

Note: If replacing a card, first disconnect any external

and/or internal cables attached to the card. Hold the metal bracket and the far top corner of the card. Carefully remove the card by pulling the card straight out of the expansion slot.

10 Insert the new card in the slot and push

straight down. Make sure the card is properly seated.

11 Reinstall the screw that holds the card to the

back panel.

Note:

9 If you’re adding a new card in a previously

unused slot, you need to remove the expansion slot cover.

Filename: ma1rwsc.doc Title: HP-Print2k.dot Template: HP-Print2K.dot Author: Ann Schmidt Last Saved By: Jerry C. Stogsdill Revision #: 198 Page: 16 of 70 Printed: 04/26/01 11:33 AM

hp pavilion home pc

If you didn’t have a screw to remove in step 8 above, you need to purchase a 6-32 x .25-inch Phillips screw to hold the card to the back panel.

To reassemble the computer:

What Is Plug and Play?

1 Close the back panel door and replace the

screws.

2 If you moved the drive, slide the drive cage

back in (see “Sliding the Drive Cage In and Out” on page 8).

3 Replace the side panel (see “Replacing the

Side Panel” on page 27).

4 Reconnect the power cord and all other

cables.

5 Reconnect the modem/phone cable. 6 Turn on the computer and all peripherals. 7 Install any software drivers supplied by the

card manufacturer.

“Plug and Play” describes the ability to add and remove add-in cards, memory, and peripherals without any special procedures (such as resetting jumpers and testing for system conflicts). The system BIOS (basic input/output system) finds these components and adds them to the system. You do not have to run the BIOS setup program.

If the New Card or Device Isn’t Working

Read through the card manufacturer’s installation instructions, and recheck all connections, including those to the card, power supply, keyboard, and monitor. If the problem still exists, run the BIOS setup program and load the default settings, and then save and exit.
