Clear CMOS
CMOS refers to the battery-powered, semiconductor chip located on computer's system board. Notebooks store
low-level settings like the system time and hardware settings in CMOS. Sometimes it is necessary to clear CMOS,
which requires removing and reinserting the 3V RTC battery for a short period of time (a few minutes before
reinserting), in addition to removing the AC adapter and battery.
NOTE: Clearing the CMOS should only be performed for troubleshooting purposes. There is no reason to clear
CMOS if the computer is working properly.
The notebook service door must be removed to access the CMOS battery. If the computer has a replaceable RTC
battery, see the RTC battery replacement section for the battery removal/replacement.

9. Soft reset (Default Settings)

NOTE: Some company policies prohibit updates or changes. Check whether the computer has custom BIOS
settings before taking action.
If your computer is having issues booting, has errors during boot, is running into issues after adding hardware, or
you are having other abnormal system behaviors that cannot be resolved through any other methods (i.e., hard
reset), it may be necessary to reset the system BIOS to default settings.
To load BIOS to default settings: Reboot the computer, and then press F10 > Main > Restore defaults. For more
information, see the BIOS F10 Setup technical white paper at http://support.hp.com, enter your computer
model, and then go to Manuals > White papers > HP PC BIOS F10 Setup Guide.
