How to recover your forgotten laptop BIOS password? There are 3 methods, each method has its strength and weakness but I am going to talk about the 2 easy methods that works across the board for everyone.
↓ 01 – Remove Internal Battery
For desktop user, open up your computer casing and look for the battery. Remove the battery for approximately 5 minutes (maybe longer, depending on the motherboard) and slot it back. By removing the battery and deprive the motherboard’s flash memory of power supply, you are essentially resetting the settings back to default when the existing data in BIOS are cleared.
This method works well for desktop, however this is not practical for laptop user unless the warranty expired long time ago. This method might or not not work, it depends on the type of motherboard.
↓ 02 – Reset CMOS With Software
PC CMOS Cleaner is the best CMOS password reset software, it works setting the BIOS to the default state or revealing the password.
PC CMOS Cleaner is an easy-to-use tool to recover, delete, decode and display the superior passwords stored in BIOS whatever the brand is. Most types of BIOS are supported. It’s an bootable CD that runs on x86 and x86_64 computers. No need to pay expensive fees to experts. It’s a useful tool for users to get their lost BIOS password back, or clean passwords from an old computer bought from others.
- Support all x86, x86_64 Personal Computers.
- Support most BIOS, such as: AWARD, AMI, Compaq, Phoenix, Samsung, IBM, Compaq, DTK, Thinkpad, Sony, Toshiba and so on.
- Display the superior passwords of the BIOS .
- Remove BIOS password(will set the BIOS to default status, need reset date).
- Set the BIOS to default state
↓ 03 – Reset CMOS With Software
The BIOS is the basic instruction set that “teaches” the computer how to access its media. If the BIOS is password protected, the computer will not function without the password. BIOS passwords are used in two ways: To prevent modification of the BIOS settings and to completely stop the computer from booting.
↓ 04 – Overload The Keyboard Buffer
Overloading the keyboard buffer can crash the password routine and let the computer boot. Try this by pressing the ESC key repeatedly, possibly more than 100 times.
↓ 05 – Remove The Hard Drive
If you’ve got crucial data on your system, need it urgently, and can’t get past the BIOS. Remember that you can always remove the hard drive with the data and access it from another system. The BIOS password (typically) only pertains to the motherboard. There are some manufacturers, IBM and Dell included, who are encrypting the HDD to the motherboard. If this is the case, try contacting the manufacturer for a password to unlock the HDD.
↓ 06 – Remove A Jumper
There’s a jumper on your motherboard that you’ll need to identify and remove. Most motherboards make your job easier by actually labeling the correct jumper as “BIOS config” or something similar. Remove the jumper, and then turn the computer on. In some cases, you will have to remove the jumper while the system is powered up, though to minimize risk, try doing this first with the computer off. In today’s quick tip I show off the quick and easy process of resetting the CMOS on your computer. Simply move the CMOS jumper to the last 2 pins for about 5-10 seconds depending on your motherboard, and then replace it back to it’s original position.
