Solved Gateway 450RGH TBX TouchChip BIOS extension is locked.

November 15, 2013 at 04:32:18
Specs: Not Applicable
I bought a Gateway 450RGH laptop computer at an ebay auction. The seller was one of those recycling places and when contacted admit that they have no records of who the original owner was.
My problem is that this computer has a fingerprint reader security system on it which must have been set for secure access by the previous owner. So now when I apply power to the computer, I get three chances to scan a fingerprint. When that fails, I get three chances to enter my Boot Security Password. When that fails, I get three chances to enter a password. (I assume a master password for the secure system). When that fails, I get a screen saying "System Disabled [00000].

I already know that the main BIOS is not locked. All BIOS passwords are set to "Clear". The only clue I have to the the locking system is a screen that appears during the startup sequence. It reads as below:

Secured by TBX TouchChip BIOS eXtension
Securing the information age.
V3.0.4f Copyright 2004 STMicroelectronics, Inc.

I'm looking for anyone who can help me solve the problem of resetting this extended BIOS password.

You will find that most of these security devices the information is stored on a separate chip on the motherboard, not in the BIOS. The information in this chip has to match information stored in a non-user accessible part of the hard disk and vice versa.

So replacing the motherboard and installing a new hard drive should get it working. The original hard drive would have been unusable and will be unusable whatever computer it was installed in.

That's what you get for buying a laptop without first checking that it works properly.

The only people that can help you is Gateway. If they are unable or unwilling then you have an expensive door stop.

Because laptops are so easily stolen this is a security measure to keep unauthorised people out. They wouldn't be very good if they were easy to circumvent.

Here's a pdf download from gateway that describes touchchip:

https://support.gateway.com/s/Mobil...

but I doubt it gives any info on disabling it. The only thing that seems possible would be a bios upgrade but that sounds too easy.

Well, I knew I was taking a chance when bidding on it. It was listed as condition unknown, parts only. No hard drive, no battery and no power supply. But, I've been collecting the 450ROG computers for quite some time. I have 10 right now and 9 are working. I enjoy repairing non-working computers I buy on ebay.
When the 450RGH came up for bid, I wanted it because it's more powerful than the ROG and it's pretty rare to find one. My winning bid was $10 and some change plus shipping. So I've pretty much concluded that there's no way to get this one working as is. Gateway is now Acer and they don't support this old of a notebook.
My last ditch effort on this is to replace the mother board. I bought one for $20 through Skyline Engineering. It should be here next week. Hopefully replacing the mother board will allow me to access the drives and install an operating system.

That's an expensive fix. I hope your original ebay purchase price made up for it.
