Remove BIOS Password on Toshiba Satelitte A135-S4637

If your system BIOS password was set and your forget it or if say another person or child set it you can reset the password with the steps below. This requires partially opening the case and shorting a part of the motherboard. If you are not comfortable doing this, get a technician to do it.

1) Remove Laptop Battery

2) Take off Memory Cover

3) Using two thumbs spread clips to outside and
pull out RAM memory. Repeat this if you have 2 modules.

4) Gently remove the vinyl cover on the motherboard. Be careful because it can rip.

5) Position the laptop so that the memory slots are facing away from you. Look for the silkscreen marking, "J1". Inside the square next to it looks like two E's one inside the other. Take a wire and short these Es out and place the other end of the wire on the case post located in the center top. Hold for about 15-20 seconds.


6) Put the vinyl cover back on.

7) Place back your RAM memory

8) Put the cover back on.

9) Put battery back in.

10) Turn the unit on, it should mention that the CMOS was reset. You should see a selection of F1
or F2 for setup. Using the F2 gets you into the Bios
menu where you reset the time and date. Then Tab over to
the Security setting tab and change your passwords. Now
hit F10 key to save the settings and your computer should reboot.

Your BIOS password should now be complete.

how can i have the password bios of laptop dell E6420


f you are running Dell servers, it is recommended to enable BIOS password. This is will prevent accidental changes done to Dell BIOS settings by others who get physical access to the server.

You can setup two different types of passwords in Dell BIOS:

System Password: This will be prompted before the system can boot up, and load the operating system.
Setup password: The system will prompt for this password only when you are trying to access the BIOS settings.

Depending on your situation, it might be a good idea to enable both the system and setup password at the BIOS level. I recommend that you at least enable BIOS password.
Press F2 for System Setup

When the Dell server is booting up, press F2 to start system setup, from where you can change Dell BIOS settings.

BIOS System Security

From the Dell BIOS main menu, scroll down to "System Security" and press enter.

Password Not Enabled

From here, you can see that both the System and Setup password is not enabled by default.

Enable System Password (and Setup Password)

Scroll to "System Password" and press enter, which will prompt you to enter the password that you like to set for the system. Please understand that if you set this password, you have to enter this password everytime you start the system. Do the same thing for Setup Password.

Don't forget this bios password. If you forget, then you have go through the painful process of resetting the Dell BIOS password.
Password is Enabled

Once you've enabled both the password, from the "System Security" menu, you'll see that that both system and setup password is enabled as shown below.

password is set

System Password Prompt (During Startup)

From now-onwards, anytime you start the system, it will not load the operating system, unless you specify the system password as shown below.

Setup Password Prompt (To Access BIOS)

If you press F2, to get to the BIOS, it will prompt for the setup password as shown below. If you don't enter a valid password here, you cannot access the Dell BIOS settings anymore.

Steps for Clearing BIOS Password Check
If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:

• Power Off a system, and remove HDD, AC and Battery from the machine.

• Open the back cover of the machine, and find out the HW Gap on M/B as picture.

• Use an electric conductivity tool to short the two points of the HW Gap.

• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.

• Restart system. Press F2 key to enter BIOS Setup menu.

• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.

NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).
