How to Reset Bios Password on Dell Laptop


Information stored in the BIOS (Basic Input / Output System), known as ESCD (Extended System Configuration Data), may sometimes get corrupted owing to a multitude of circumstances such as energy incidents, inaccurate user settings, hardware incompatibility owing to a particular environment, or a No POST or No Video scenario. In these cases, it may be necessary to reset the BIOS or CMOS (Complementary Metal–Oxide–Semiconductor) to “Factory Defaults,” or to clear the NVRAM (Non-Volatile Random Access Memory) in other circumstances. Be cautious when changing the settings of the BIOS. The BIOS interface is intended for sophisticated users, you can alter a environment that might stop your computer from beginning properly, and you might experience a potential data loss.

Resetting the BIOS defaults from the Reset Defaults Option

  1. Reboot the system. Click Start, Restart and Turn Computer.
  2. Tap F2 to enter the BIOS on the Dell loading screen. When the command has been recognized, “Entering Setup” will appear. Some designs may use another key. During the boot process, the key will be shown. The key is F2 for the majority of Dell laptops and desktops.
  3. Once loaded, depending on the BIOS age and type, the defaults can be reset by either loading the factory defaults using the F9 key to Load Defaults (Shown as an option at the bottom of the screen), the Alt+F key combination, or the Load Defaults button on the screen.
  4. Press Esc on your keyboard and select Save and Exit, or press Exit again, depending on your variant.
  5. To save all modifications, select the Enter key and exit the BIOS screen. Allow resetting of your system for BIOS settings.

How to clear the CMOS, BIOS or NVRAM from a Jumper

This can be accomplished by manipulating the RTCRST (Real Time Clock Reset) jumper on the system board when the ESCD contained in the NVRAM needs to be cleared. Once the jumpers are set properly and power is provided, the BIOS on the system will be reset. RTCRST–Clears NVRAM. When the jumper is closed, the NVRAM will be removed (use the password bridge jumper (PSWD)). AC power must be applied to the system for about 10 seconds (not necessarily switched on) while the jumper is closed. You can use the above RTCRST jumper procedure to try to recover from a scenario like No POST, No Video.

Clearing the CMOS settings:

  1. Turn off the laptop and disconnect from the electrical outlet the power cable.
  2. Remove the cover of the laptop.
  3. Locate the system board’s 2-pin password connector (PSWD).
  4. Remove the jumper plug with 2 pins.
  5. Locate the system board’s 2-pin CMOS jumper (RTCRST).
  6. Move the 2-pin jumper plug into the CMOS jumper from the password jumper to the buttons.
  7. Connect AC power to the scheme and wait for the CMOS to clear for ten seconds.
  8. Return the 2-pin jumper connector to the jumper password.
  9. Replace the cover of the laptop.
  10. Connect and switch on your desktop and devices to power outlets.

How to clear CMOS, BIOS and NVRAM by reseating the CMOS battery

This is another way to update the BIOS on the system by merely removing the coin cell battery from the CMOS and then clearing the system energy. This is usually performed if you are unable to access the jumpers on a desktop system or deal with a laptop system.

  1. Disconnect the system from an internal energy source, remove the main battery on a laptop
  2. Remove the computer cover and find the CMOS coin cell battery
  3. Remove or disconnect the coin cell battery
  4. Press the control button for at least 10 seconds to drain all remaining energy from the re-insert or re-connect the coin cell battery
  5. Remove or disconnect the device and check functionality

Clearing the System Dell Bios Password

  1. Remove the cover of the laptop.
  2. Locate the system board’s 2-pin password connector (PSWD).
  3. Remove the jumper plug of 2 pins and set aside the jumper plug.
  4. Replace the cover of the laptop.
  5. Connect your mouse and keyboard, connect your laptop and monitor to and switch on electrical outlets.
  6. Turn off the desktop after the loads of the operating system.
  7. Disconnect the keyboard and mouse, then disconnect from their electrical outlets the laptop and monitor.
  8. To ground the system board, press the energy button on the laptop.
  9. Remove the cover of the laptop.
