Adding Memory 5 Click HP technical support. The motherboard contains sockets for DDR DIMMs (double data rate dual in-line memory modules). 6 Search for your PC model number, and then search for “upgrading memory” to find out your system configuration and memory requirements. To determine the memory capacity and speed of the memory module your PC model uses, and for specific memory module information and specifications: The motherboard contains 184-pin DDR DIMM sockets.
About Installing DDR DIMMs 4 Move any cabling out of the way, if necessary. DDR DIMMs must be 184-pin unbuffered DDR SDRAM (double data rate synchronous dynamic random access memory). The HP Pavilion ships with one or more memory modules, but you can replace the existing memory modules with highercapacity ones. You can install 128 MB, 256 MB, 512 MB, or 1024 MB (1GB) memory modules in the PC. 5 Push down the two retaining clips on the ends of the socket until the memory module pops out of the socket.
Installing a Memory Module 1 See “Removing a Memory Module” on page 25. 2 Holding the new memory module by its edges only, remove it from the antistatic packaging. (Avoid touching the memory chips or the gold contacts on the module.) The memory module has one or two small notches on the lower edge, which fit into raised bumps in the memory socket. 3 Hold the memory module in alignment with the socket, aligning the notches with the bumps. Warning: Do not pull the memory module out of the socket.
4 Push straight down on top of the memory module until it is fully seated in the socket. The retaining clips on the ends of the socket automatically lock it into position when the memory module is fully seated. Add-In Cards At some point, you may want to add a PCI or an AGP card to the PC to accommodate a new component, such as a scanner, or to upgrade an existing card. Warning: Do not overload the system by installing add-in cards that draw excessive current.
Removing an Add-In Card 1 Remove the side panel that has thumbscrews. See page 4. 2 Gently lay the PC on its side. 3 To prepare an empty card slot for a new card, loosen the screw of the expansion slot cover. Remove the cover of the empty slot. 4 If you are replacing a card, make a note of any external or internal cables attached to the card, and then disconnect them. 5 Loosen the screw on the bracket of the card you are replacing. 6 Hold the bracket and the far top corner of the card.
Installing an Add-In Card 1 Insert the new card into the slot and push straight down. Make sure the card is properly seated. 2 Attach the screw to secure the card you have replaced. 3 Connect any external or internal cables attached to the card. 4 Replace the side panel. See page 5. Note: 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.
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. Replace only with the same, or equivalent, type of battery.
