Once the master password is inserted, it will erase any security on the drive by the BIOS. I still have not tried a two different PC/Laptops with Insyde H2O to see if they are interchangeable and unlock-able. 5x4 decimal digits. 5 decimal digits. Hewlett-Packard/Compaq Netbooks. Insyde H20 (generic).

Try one of the following codes:
* for some Dell codes press Ctrl-Enter, not Enter, when entring code into the BIOS

It happens more often than you’d think – access to the bios of your laptop is locked & you’ve forgotten the damn password. All you remember is entering a really clever new password at the time. sigh
As is the case with many electronic devices, a locked bios will often provide an ID that – with enough clever reverse engineering – will reveal the tricky password that you entered then promptly forgot. (Note to self: Do not play with bios whilst drunk) All you need is to know the algorithm used to calculate the password. Which 99% of us do not know.
After usually 3-5 attempts at the password, the laptop will respond with something similar to “This laptop ABCD12345-ZYX is locked. Restart to enter the correct password.” It’s that laptop ID that leads us to the password, eventually.
Fortunately, Megabyte @1024kb.co.nz has a pre-built solution for many (but not all) laptop bios locks. Covering HP, Dell. Sony, Toshiba, Fujitsu, BenQ, Asus, Acer and more, it’s worth giving it a try. Especially since it’s posted on this site & it’s free to use.
If you have a problem with a locked bios, obtain the machine ID mentioned above then go here. Enter the ID, press the button, profit. The response will ID the brand of laptop and provide your password.
