HP Z1 Maintenance And Service Guide

CPU (processor) and CPU heatsink
CAUTION: Observe the following cautions when removing or replacing the heatsink.
— When removing the heatsink, loosen all screws a little at a time to ensure the CPU remains level. Do
not fully loosen one screw, and then move on to the next.
— Do not overtighten the heatsink screws. Overtightening can strip the threads in the chassis.
CAUTION: Observe the following cautions when removing or replacing the CPU.
— Internal components might be powered even when the computer is off. To prevent damage,
disconnect the computer power cord before you remove or install a component.
— Do not touch the CPU socket contacts or the gold pads underneath the CPU. Use extreme care and
handle the CPU only by the edges.
— The CPU socket contacts are delicate and bend easily. To avoid bending the contacts, use extreme
care when installing the CPU in the socket.
— Installing a processor incorrectly can damage the system board. Contact an HP authorized reseller
or service provider to install the processor. If you plan to install the processor yourself, view the entire
remove and replace video before you begin.
— Failure to follow the computer preparation instructions can result in an improperly installed
processor, causing extensive computer damage.
NOTE: When you power off the computer through the operating system, power consumption falls
below what is considered low power consumption but does not reach zero. This low power
consumption feature extends the life of the power supply.
Expansion slots
The workstation has the following expansion slots:
●
One MXM slot that supports Type A and Type B cards (dedicated for graphics)
●
Three Mini PCIe slots that support full-length mini-PCIe cards

CAUTION: To prevent damage, the overall power consumption of the computer (including I/O
cards, CPU, and memory) must not exceed the maximum rating of the computer power supply. For
power supply information, see
Power supply specifications on page 51.
