From the front, push the full-size drive (or the filler) all the way into the chassis. Secure the drives by pushing in the optical drive latch (H). Connect the data cable plug and the power cable plug to the connectors on the back of the slim optical disk drives.
Page 35
Adding or replacing a full-size optical disc drive Remove the rails from the full-size drive filler, or the existing drive, and install the rails on the replacement drive. Complete the following steps: Position the filler or the existing drive with the top of the unit (A) facing up. Remove the two screws and the rail (B) on the left side of the unit.
Page 36
Hold the drive with the top facing toward the right. Specifically, the disc tray (E) faces toward the right. Slowly insert the drive into the chassis through the front. If the drive starts to bind or becomes stuck, stop inserting it. Remove the drive and check that the rails are correctly installed and that the top of the drive is facing toward the right.
Connect the data cable plug and the power cable plug into the connectors of the replacement full-size optical disc drive. If you are adding a drive, route the cables and connect them at the motherboard and the power supply. Close the access door and the computer. See “Opening and Closing the Computer” on page 1.
Adding or replacing a hard disk drive If necessary, remove the existing drive. See “Removing the hard disk drive” on page 33. Tip the left side of the drive into the drawer, and insert the pins (B) into the drive. If necessary, adjust the position of the pins on the left side (A) to match the drive.
With the handle (G) released (up), align the drawer with the chassis slot, slide the drawer into the chassis, and then press the face of the drawer (F) to fully seat it into the power and SATA data connectors at the back. CAUTION: The computer may not recognize the drive if the drawer is not fully seated.
To determine which type and speed of memory module your computer uses, and for specific memory module information and specifications, go to the Web site listed in your Limited Warranty and Support Guide, and click the Support link. WARNING: Using the wrong type of memory module could damage the computer.
Push down the retaining clip on each end of the memory socket until the memory module pops out of the socket. WARNING: Do not pull the memory module out of the memory socket. Use the retaining clips to remove the module. Lift the memory module out of the memory socket.
Page 42
Press the module into place, and ensure that the retaining clips close by pressing them toward the module. If necessary, replace the card you removed from the top add-in card slot. See “Removing and Installing an Add-in Card” on page 39. Replace the thermal divider, replace and close the PCI door, close the left access door and the computer.
IMPORTANT: Removal and installation of liquid-cooled graphics cards is not documented here. To service or upgrade liquid-cooled graphics cards, contact HP Support. Removing an add-in card Prepare the computer to be opened, and then open the left access door, open and remove the PCI door, and remove the thermal divider.
Page 44
Inside the chassis, press the latch (B) to release the add-in card you want to remove. The following figure shows a depressed latch (C). CAUTION: Your computer may have a latch similar to (D) on the add-in connector. Pull up the latch (D) to release the card from the connector when removing the card.
Page 45
IMPORTANT: Use only a slot cover that came with your computer. If you are not replacing the old add-in card, insert the metal slot cover into the open slot. From the outside of the chassis, press the slot latch (E) to lock the slot cover in place.
Installing an add-in card If necessary, remove the add-in card slot cover or the existing add-in card. See “Removing an add-in card” on page 39. Locate the card slot on the motherboard inside the chassis. In the following figure, (A) is a PCI-E (Express) x 16 connector, and (B) is a PCI connector. Your computer may vary.
Page 47
From the outside of the chassis, press the slot latch (E) to lock the card in place. (See the Warning that follows.) The following figure shows a locked slot latch at (F). WARNING: Do not force the slot latch to close. Check inside the chassis that the card (G) fits against and around the alignment pin (H).
Page 48
When connecting to the power supply, match the power supply connector color to the plug, and check the power supply label for connector usage. Your power supply may vary from the figure. For more power supply information, see “Removing and Replacing the Power Supply”...
Removing and Replacing the Power Supply Removing the power supply Prepare the computer to be opened, and then open the left access door, open and remove the PCI door, remove the thermal divider, and remove the power supply baffle. See “Opening and Closing the Computer” on page 1. WARNING: Remove the power cord from the computer.
Page 50
On the back of the chassis, loosen the four screws (B) that secure the power supply assembly in the chassis. From inside the chassis, push out the power supply assembly through the back of the chassis. Remove the four screws (C) that secure the power supply bracket to the power supply, and then remove the bracket.
Replacing the power supply Align the four (inner) screw holes in the power supply bracket (C) with the screw holes on the face of the power supply. Insert four screws (C) to secure the bracket to the power supply. From the back of the chassis, insert the power supply assembly into the opening (D). Tighten the four screws (B) in the bracket to secure the power supply assembly in the chassis.
Page 52
Inside the chassis, connect the plugs previously removed from the power supply. Match the power supply connector color to the plug, and check the power supply label for connector usage. WARNING: If you disconnect the power connector for the liquid cooling system, ensure that it is reconnected prior to connecting power and turning on the computer.
12V2 (CPU), turquoise connector 12V5 (PCI-E), blue connector Replace the power supply baffle and the thermal divider, replace and close the PCI door, close the left access door and close the computer.

Reconnect the plugs (F) at the top of the card. Reconnect the five SATA data cable plugs (D1–D5). Insert new tie-wraps (C) through the anchors and around the SATA data cables, and then tighten the tie-wraps to secure the cables. On the left side of the computer inside the hard disk drive drawer bay, reconnect the the power plug (A) to the SATA backplane (B).
Replacing the Battery A lithium battery on the motherboard provides backup power for the computer timekeeping capability. The battery has an estimated life expectancy of seven years. When the battery starts to weaken, the date and time may become incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery.
