How to Reset BIOS Password – Simple Guide for Everyone
The problem usually occurs when we forget an old password, when we buy a used computer, or when someone else has changed the settings without informing us. Fortunately, there are tried-and-true solutions that work even for beginners.
What is BIOS and why is there a password?
The BIOS is the computer's basic "boot system." It's the first thing that runs when you press the power button to turn it on, and it checks that all the essential parts are working properly.
The BIOS password is added for security reasons. It prevents third parties from changing critical settings, which is useful in offices, schools, or homes with children. However, when forgotten, it can become a real headache.
⚠️ Be careful before you start
The following methods do not delete files, but reset settings. If you have important settings or special connections, it is a good idea to remember or write them down.
Practical Ways to Reset BIOS Password
1️⃣ Removing the small battery
Inside every computer is a small, round battery. This holds the basic settings and password. If it is removed for a short time, the computer "forgets" the password.
Steps:
- Close completely the computer and unplug it 🔌
- Open the side cover of the box (or the bottom lid on a laptop)
- Locate the battery – looks like a watch battery
- Remove the battery and wait 10–15 minutes ⏱️
- Put the battery back in. in the same place
- Close the lid. and turn on the computer
💡 Everyday example
It's like taking the batteries out of a watch. When you put them back in, the time is reset – the same goes for the code.
2️⃣ Using a small reset switch
Many computers have a small switch near the battery that resets the settings. Not all models have it, but it's worth checking.
- Shut down and unplug the computer.
- Open the lid
- Find the small switch near the battery
- Move it for a few seconds
- Put it back in place and turn on the computer.
3️⃣ Special recovery codes
On some computers, after several incorrect attempts, a number appears on the screen. This can be used to unlock through the company.
This solution is more common on laptops and requires a little searching on the manufacturer's page.
4️⃣ Testing simple and common passwords
Before you proceed to open the computer, it is worth trying some very common codes:
- Empty field (just press Enter)
- admin
- Password
- 123456
- The name of the computer company
5️⃣ Contact the company
If nothing works, the safest solution is to contact the manufacturer. They often ask for the model and serial number to guide you properly.
Safety Tips

What to do after the reset
After a successful reset, you may need to set the time and date again. This is normal and will take a few seconds.
💡 So that it doesn't happen again
If you set a new password, write it down somewhere safe. A small piece of paper in a drawer is better than having to re-stick it.
