Laptops due to the fact that they are highly portable, are always an easy target for thief’s. Quite a few years ago now, PC makers started implementing a more secure password system on modern Laptops in particular.
Whilst this implementation is very secure and works well in most cases it can also present many problems for legitimate laptop users who genuinely need to recover their BIOS or BIOS password.
Common scenarios would include forgetting ones password, or letting the kids play with the laptop and they inadvertently set a password on the machine.
Lending the laptop to a needy friend who then sets a password on the hard drive to do you a favour and then does the same to the setup screen and forgets them. And of course possibly another scenario would be that one has a stolen machine on ones hands.
In some cases If you have a receipt for your Laptop, the laptop maker may be able to help you remove the password. Some makers respond better than others, some offer no support under such circumstances.
Older Laptops and most pcs can have the password cleared by clearing CMOS or resetting the laptop. This is simply not the case with modern Laptops.
Desktop Password Removal
Start by clearing CMOS if you cant find a jumper to do this then remove the CMOS battery from the machine after powering down.
Some Desktop mainboards have a password clear jumper, if this is the case then use this jumper to enable or disable any system password.
Laptop Passwords Removal
We do not specialise in password removal, each machine is quite different and needs to be researched separately, you would need to do this yourself in most cases
If the password isn’t removed by using the clear CMOS jumper or by removing the battery, then you probably have a machine that utilises a second EEPROM to back up the password (Enhanced password protection).. Most modern laptops have the second backup EEPROM fitted.
Nothing can be achieved by changing the BIOS Chip only in these machines. The Security eeprom content would need to be amended also as it would simply restore the password into the main BIOS or result in a non booting machine.
Some makers machines cannot be restored using the BIOS code alone after a failed flash, as it doesn’t contain vital security code that was present when the machine was manufactured, the machines instantly sense they have been tampered with and shut down or even fail to power up.
Obviously in most cases Laptop makers do not release the needed information to recover passwords as it would undermine their security efforts.
Each machines security system layout could be slightly different or use a different EEPROM for backup purposes. You would need to research your individual password issue yourself
The modern password security systems normally involves a second SOIC 8 pin eeprom usually an Atmel 93c or similar EEPROM located somewhere on the mainboard and usually this is fitted well away from the main system BIOS or EEPROM.
Laptop Security EEPROM
In most cases clearing the security EEPROM of the Laptop and using a Fresh Preflashed or programmed EEPROM will clear the System BIOS Password. In fact it may only be neccassary to clear the security chip and clear cmos however i have not confirmed this as yet.
We do not specialise in password removal however if you have managed to locate your security eeprom and can send it to us we can erase and blank check it for you. After this your on your own any crc errors or other problems you will have to deal with on your own as this is the best we can do to help.
