Expansion card For a list of available expansion cards, see Computer major components on page The computer has one PCI Express ×1 expansion socket and one PCI Express ×16 expansion socket. NOTE: You can install a PCI Express ×1, ×4, ×8, or ×16 expansion card in the PCI Express ×16 socket. For dual graphics card configurations, the first (primary) card must be installed in the PCI Express ×16 socket.
Page 28
If you are removing a PCI Express ×1 card, hold the card at each end, and carefully rock it back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket. If you are removing a PCI Express ×16 card, pull the retention arm on the back of the expansion socket away from the card (1), and carefully rock the card back and forth until the connectors pull free from the socket.
Page 29
To install a new expansion card (PCI Express ×16 shown), hold the card just above the expansion socket on the system board, and then move the card toward the rear of the chassis so that the bracket on the card is aligned with the open slot on the rear of the chassis. Press the card straight down into the expansion socket on the system board.
Drives For a list of available drives, see Computer major components on page When installing drives, follow these guidelines: The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA connector on ● the system board labeled SATA0.

Memory For a list of available memory modules, see Computer major components on page The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to two industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM.
assigned to single channel. If one channel will have more memory than the other, assign the larger amount to Channel A. In any mode, the maximum operational speed is determined by the slowest DIMM in the system. ● Removing and installing DIMMs IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules.
The lithium battery is only used when the computer is not connected to AC power. HP encourages customers to recycle used electronic hardware, HP original print cartridges, and rechargeable batteries. For more information about recycling programs, go to http://www.hp.com/recycle.
Fan duct The fan duct sits on the fan sink and is secured to the fan sink with tabs. Prepare the computer for disassembly (Preparation for disassembly on page 16). Remove the access panel (Access panel on page 18). Remove the power supply cable from the clips on the duct. Pull the tabs away from each other (1), and then lift the duct off the fan sink (2).
Fan sink IMPORTANT: The bond between the fan sink and the processor may be very tight. If the computer will power on, before removing the fan sink, turn on the computer until it warms the fan sink. Warming the fan sink loosens the bond between the heat sink and the processor, thereby making separating them easier.
After installing a new processor onto the system board, always update the system ROM to ensure that the latest version of the BIOS is being used on the computer. The latest system BIOS can be found on the Web at: http://www8.hp.com/us/en/support-drivers.html. Chapter 4 Removal and replacement procedures...
