HP 6710b Service Manual

To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left and

right sides of the computer.

The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is

designed to turn on automatically when high temperature conditions exist. These conditions are affected

by high external temperatures, system power consumption, power management/battery conservation

configurations, battery fast charging, and software applications. Exhaust air is displaced through the

ventilation grill located on the left side of the computer.

All heat sink spare part kits include thermal material.

Before removing the heat sink, follow these steps:

Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the

computer on, and then shut it down through the operating system.

Disconnect all external devices connected to the computer.

Disconnect the power from the computer by first unplugging the power cord from the AC outlet and

then unplugging the AC adapter from the computer.

Remove the battery (see 

Release the keyboard (see 

).

Remove the switch cover (see 

).

Remove the internal memory module (see 

). This step applies

only to HP Compaq 6710 computer models.

Remove the fan (see 

Remove the heat sink:

Step 1 applies to HP Compaq 6715 computer models. The heat sink on HP Compaq 6710

computer models is secured to the computer by captive screws which must be loosened rather than

removed.

Remove the four Phillips PM2.0×6.0 screws (1) that secure the heat sink to the system board.

Release the heat sink (2) by lifting the right side until it disengages from the processor.

Due to the adhesive quality of the thermal material located between the heat sink and

processor, it may be necessary to move the heat sink from side to side to detach the heat sink from

the processor.
