If the computer you are servicing has an unknown user password, follow these steps to clear the
password:
NOTE: These steps also clear CMOS.
1. 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.
2. Disconnect all external devices connected to the computer.
3. 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.
4. Remove the battery (see Battery on page 44).
5. Remove the real-time clock (RTC) battery (see RTC battery on page 66).
