Dell System Password Problem

  • 0

I have a Dell OptiPlex 745 and I changed my System Password to nothing. If I start up my PC it says I have to enter my password, but when I don’t enter anything it just asks again, Old password doesn’t work. I have tried a lot of key combinations, but they don’t work. Please Help!

    1. If you can’t figure out the password anymore, reset the CMOS:
      Look for the “password reset jumper” inside the box.

      Clearing CMOS Settings
      1. Follow the procedures in Before You Begin.
      2. Reset the current CMOS settings:
      a. Locate the password (PSWD) and CMOS (RTC_RST) jumpers on the system board (see Jumper Settings).
      b. Remove the password jumper plug from its pins.
      c. Place the password jumper plug on the RTC_RST pins and wait approximately 5 seconds.
      d. Remove the jumper plug from the RTC_RST pins and place it back on the password pins.
