Hewlett-Packard notebooks include a BIOS setting that allows you to keep the ProBook 6460B cpufan on constantly when the notebook is plugged in. Using this setting — called “Fan Always On” — allows you to test your notebook’s fan to be sure that it spins freely and has power. To keep your business computers running smoothly, if your test reveals a problem with the fan, take the notebook to an HP certified repair center to avoid voiding the warranty.
Step 1
Power on your HP notebook, and when the post screen comes up, press “F10” to enter the BIOS setup. The post screen is the screen that comes up first when you boot the computer. It lists the key for entering the BIOS. You may have to press “F10” several times before the BIOS comes up. If the Windows screen comes up, allow the computer to finish booting, then power it down to try again. You may have to try several times before you enter the BIOS.
Step 2
Use the arrow keys to scroll through the BIOS list until you highlight “Advanced.” Press “Enter.”
Step 3
Use the arrow keys to scroll down to “System Configuration,” then press “Enter.” Use the arrow keys to navigate to “Device Configurations,” then press “Enter.”
Step 4
Use the arrow keys to navigate to “Fan Always on when A/C Power,” then press “Enter” to enable it. Press the “F10” key to save the setting and exit the system BIOS.
Step 5
Plug your notebook into a working wall outlet and verify that the notebook is receiving power. HP notebooks usually have an LED light around the A/C plug or on top of the computer that indicates it is receiving power.
Step 6
Power on your notebook and listen for the fan to be sure it is running freely. If the ProBook 6460B cpufan is spinning without making any loud vibration noises, it is getting power from the motherboard and is not getting stuck on other internal hardware. If it is not spinning, or if it is making loud vibration noises, it indicates a problem, in which case consult a certified technician (link in Resources).
