Computer Setup (F10) Utility Recovering the Configuration Settings There are two ways to recover the Configuration Settings established in the Computer Setup (F10) Utility. Method One: Flash ROM CMOS Archive and Restore Feature-Using Power Switch Override F10 Computer Setup CMOS Configuration Settings are stored in Non-Volatile RAM (NVRAM). Each time the computer starts, the system ROM saves a copy of NVRAM (including CMOS, passwords, and other system variables) in the flash ROM. Should the system become unstable, the last known good copy of NVRAM can be restored using a feature called "power button override." To restore NVRAM do the following: 1. With the unit powered down, press and release the power button. 2. Immediately after pressing the power button (during POST), press and hold the power button until the unit powers down (about four seconds). At the next startup, the ROM detects this "power button override" event and the backup copy of NVRAM is restored automatically. Ä CAUTION: Unplugging the power cord during POST can corrupt the splash screen (the logo screen seen during POST). Flashing the ROM is required to restore the splash screen, although the computer will continue to function normally. ✎ Because of the "power button override "feature, you cannot power off the computer with the power button immediately after powering up during POST (Power-On Self-Test). The video display must be active before the computer can be powered off by pushing the power button. Computer Setup (F10) Utility Guide www.hp.com 25
