    Davos finds that a disgruntled former employee decided to sabotage hercomputer when she left by putting a password in CMOS that stops thecomputer from booting. What can Davos do to solve this problem?

    • Davos should boot the computer holding the left SHIFT key. This will clear the CMOS information.
    • Davos should try various combinations of the former employee’s name. The vast majority of people use their name or initials for CMOS passwords.
    • Davos should find the CMOS clear jumper on the motherboard. Then he can boot the computer with a shunt on the jumper to clear the CMOS information.
    • Davos should find a replacement motherboard. Unless he knows the CMOS password, there’s nothing he can do.

    Richard over in the sales department went wild in CMOS and made a bunch ofchanges that he thought would optimize his PC. Now most of his PC doesn’twork. He can boot, but only to CMOS, not into Windows. Which of thefollowing tech call answers would most likely get him up and running again?

    • Reboot the computer about three times. That’ll clear the CMOS and get you up and running.

    • Open up the computer and find the CMOS clear jumper. Remove a shunt from somewhere on the motherboard and put it on the CMOS clear jumper. Reboot and then put the shunt back where you got it. Reboot, and you should be up and running in no time.

    • Boot into the CMOS setup program and then find the option to load a plugand- play operating system. Make sure it’s set to On. Save and exit CMOS; boot normally into Windows. You should be up and running in no time.

    • Boot into the CMOS setup program and then find the option to load Optimized Default settings. Save and exit CMOS; boot normally into Windows. You should be up and running in no time.
