Use this guide to clean and replace the internal CPU fan and/or heat sink on the HP Elitebook 8460p if it is failing, broken, or if your device is excessively overheating. Signs that the fan has failed, or is failing, can be spotted if the computer frequently shuts down and restarts and displays a warning about overheating and if you do not hear the fan run when the computer initially starts up.
Heat can damage the internal components of the laptop easily if it is not properly controlled. If you are having problems with the operation of the fan, attempt to fix the problem as soon as possible and avoid using the computer as much as possible before fixing the problem.
When opening the laptop up to repair, replace, or clean the fan, make sure to ground yourself with an ESD strap to prevent electrostatic discharges from damaging sensitive components in the laptop such as the motherboard or the processor.
To complete this guide, you will need an ESD strap and a Phillips #0 screw driver.
