A serious problem prevents you from entering the BIOS permanently - here is the complete solution to regain control of your device
If you've tried to access your computer's BIOS settings and were prompted to enter the password without knowing it, you're not alone. Forgetting or losing your BIOS password is one of the most common and frustrating problems, especially for those who want to activate the boot menu or install a new operating system. In this exclusive article from Thinker's Castle for Informatics, we provide you with all the effective and safe solutions to overcome this problem without the need for a technician, with a detailed explanation of each step. Read on to learn the correct way to regain full control of your computer.
What is the reason for not entering BIOS?
The login issue usually occurs when BIOS errors are caused by a pre-activated password set by the user or company, and this is one of the most common causes, especially on used computers. The problem can also be caused simply by pressing the wrong key during startup, as BIOS entry keys vary from manufacturer to manufacturer (e.g., F2, Delete, Esc, F10). Sometimes, enabling the "Fast Boot " option causes the BIOS to skip too quickly, preventing you from entering it in time. Keyboard failures or changes to UEFI settings can also cause the same result. Therefore, it is important to determine the correct cause first before attempting a solution.
The problem of not entering the BIOS is most often due to one of the following reasons:
1. BIOS password is enabled.
As in your case, a password may have been set previously, and you won't be able to enter the BIOS unless you enter it or reset it.
2. Pressing the wrong key
Each company has a different key to enter the BIOS (e.g., F2, Delete, Esc, F10). If you press the wrong key, you won't be able to enter.
3. Enable "Fast Boot" or "Ultra-Fast Boot."
Some modern devices skip the BIOS screen very quickly, making it difficult to enter it the usual way.
4. Keyboard malfunction
If the keyboard is not working properly before the system boots, the keystroke will not be registered.
5. Problem with system settings or UEFI
On some devices, only UEFI may be enabled, preventing the traditional BIOS screen from appearing.
What is a BIOS password and why does it appear?
A BIOS password is a security measure that prevents anyone from modifying sensitive system settings such as boot order, enabling or disabling components, etc. It's often set to protect the device from tampering, but forgetting it or purchasing a used device with an enabled password can be a major problem.
Signs that indicate a BIOS password
- The "Enter Password" window appears when trying to enter BIOS or the boot menu.
- Unable to access boot settings or change boot order.
- The device gets stuck at a screen asking for a password that cannot be bypassed.
Easy Solutions to Bypass BIOS Password
1. Try default passwords
Some devices use default passwords that are set at the factory; try the following:
admin, 0000, password, 1234
Manufacturer names such as: Dell and Toshiba
✅ This method may work on old or not fully secured devices.
2. Contact the seller or previous user.
If you purchased the device used, contact the seller and request the password. The previous user will likely have memorized it.

- Remove it for 5-10 minutes.
- Reinstall it and then turn on the device.
⚠️ Note: This method does not work on most modern devices.
4. Use the CLR_CMOS jumper to clear the settings.

5. Create a master password using the error code.
Some devices, after 3 failed attempts, display the "System Disabled" icon.
- Record the code.
- Use master password generator sites like
- bios-pw.org
- unlockbiosrecovery.com
- Enter the resulting password.
⚠️ This method only works on some models of Dell, HP, Acer, etc.
6. Reprogram BIOS chip (flash EEPROM)
If all else fails:
- Use an EEPROM programmer such as CH341A.
- Remove the BIOS chip from the motherboard.
- Reprogram it with a new BIOS file from the official website.
⚠️ Experience in welding and precision programming is required.
The last and safe solution
7. Contact the manufacturer's support.
- Go to the company's official support website.
- Submit a BIOS unlock request along with proof of ownership of the device (invoice/image of serial number).
- They will provide you with an official unlock password or steps specific to your device.
Tips to avoid the problem in the future
- Do not set a BIOS password unless necessary.
- Keep it in a safe place or use password storage software.
- Do not purchase used computers with a BIOS password unless the lock can be removed.
