Removing an Optical Drive 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Remove the front panel. See “Removing the Front Panel” on page 3. 3 Gently lay the PC on its side. D Replacing or Adding an Optical Drive 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Remove the front panel. See “Removing the Front Panel” on page 3.
Removing a Memory Card Reader or a Diskette (Floppy) Drive 5 Remove the screw from the side of the drive cage to remove the memory card reader or the diskette drive. Your PC has a drive cage that can hold a memory card reader and a diskette drive. You can replace either of these drives if they are included with your model. The PC may have a fixed or a removable drive cage that holds the memory card reader and the diskette drive.
5 Hold the release tab down as you pull the cage towards the back of the chassis, and then lift it out (F). Removing the drive cage provides more space to remove the cables. F Installing a Memory Card Reader or a Diskette (Floppy) Drive The PC may have a fixed or a removable drive cage that holds the memory card reader and the diskette drive. If the drive cage is fixed, follow the first set of instructions, “To install a drive (with a fixed drive cage) (select models)” on page 7.
3 Attach the cables to the drive you are installing. 4 Install the screw to secure the drive you are installing to the drive cage. 5 Replace the front panel. See “Replacing the Front Panel” on page 3. 6 Complete the procedures to replace the side panel, and to close the PC. See “Opening and Closing the PC” on page 1.
To remove a hard disk drive (with a hard disk drive cage) (select models) 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Gently lay the PC on its side. 3 Make a note of each cable attached to the hard disk drive before removing the cables. 4 Remove the power and data cables from the back of the hard disk drive.
To remove a hard disk drive (without a hard disk drive cage) (select models) 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Remove the front panel. See “Removing the Front Panel” on page 3. 3 Gently lay the PC on its side. 4 Remove the four screws from the front of the chassis that secure the hard disk drive. Lift the hard disk drive out of the chassis. 6 Remove the power and data cables from the back of the hard disk drive.
Replacing a Hard Disk Drive The hard disk drive of your PC may be located inside a cage. If it is, follow the first set of instructions, “To replace a hard disk drive (with a hard disk drive cage)” on page 11. If your hard disk drive is not located inside a cage, follow the second set of instructions, “To replace a hard disk drive (without a hard disk drive cage)” on page 12.
To replace a hard disk drive (without a hard disk drive cage) 1 Connect the power and data cables to the back of the hard disk drive. For a Parallel ATA hard disk drive, connect the data IDE cable end labeled Master to the drive. Connecting the Serial ATA hard disk drive cables MA ST ER 2 Place the hard disk drive inside the chassis. Align the drive with the four screw holes on the front of the PC to secure the hard disk drive. Insert and tighten the screws.
1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Remove the front panel. See “Removing the Front Panel” on page 3. 3 Gently lay the PC on its side. 4 If you are also removing the hard disk drive, see “Removing a Hard Disk Drive” on page 8. WARNING: For Parallel ATA drives, connect the data IDE cable end labeled Master to the primary hard disk drive; connect the data IDE cable plug labeled Slave to the second hard disk drive.
8 Place the second hard disk drive inside the chassis and align it with the screw holes (P) on the front of the chassis. Use four regular 6/32 x ¼-inch screws (not included) to secure the hard disk drive to the front of the PC. Tighten the screws from the front of the PC chassis into the drive.
Removing a Second Hard Disk Drive 1 Complete the procedures to prepare the PC and to remove the side panel. See “Opening and Closing the PC” on page 1. 2 Remove the front panel. See “Removing the Front Panel” on page 3. 3 Gently lay the PC on its side. 4 See “Removing a Hard Disk Drive” on page 8. 8 Make a note of each cable attached to the second hard disk drive before removing the cables. 9 Remove the power and data cables from the back of the second hard disk drive.
Adding Memory The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). The exact number of sockets depends on which model you have. 5 Push down the two retaining clips on the ends of the socket until the memory module pops out of the socket. 6 Hold the memory module by its edges only, as you lift it away from the socket. Store it in its antistatic packaging.
3 The memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Push the module carefully and firmly into the slot, ensuring that the latches on both ends snap into place. Removing an Add-in Card 4 Replace any cabling that was removed. 5 Complete the procedures to replace the side panel and close the PC. See “Opening and Closing the PC” page 1.
Installing an Add-in Card Replacing the Battery A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability. The battery has an estimated life expectancy of seven years. When the battery starts to weaken, the date and time may be incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery. WARNING: There is danger of explosion if the battery is incorrectly replaced.
