TOSHIBA THINKPAD T23 BIOS PASSWORD

[Shak]

Hi guy's need your help this time?

I have a T23 Tosh thinkpad which I use at the workshop as a back up for GT1,Its asking for a BIOS password on boot up.
This has never happened before.
Is there a simple way to unlock the BIOS password?
I can build a simple circuit and wire it into the motherboard and unlock it,but I can't seem to find a place were I can buy a few electronic components.

The parts that I need are:
2x 2.2k ohm resistors
2x c5v1 or BZX55 Zener diodes
1x Serial port 9 pin female

This circuit will unlock most Toshiba passwords/Bios.

Did you try shorting the battery wires?

Yes it didnt work!

Yes it didnt work!

We're talking about the Bios battery, right? I always thought that if that doesn't do it, then nothing can.

Resetting the BIOS Password using Hardware

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.

Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.

if you can't still solve this bios problem just let me know :)

Thanks for the info matey,but I have tried all tricks for the T23 .

Just found out that if you short out a few pins in the parallel port socket it wipes the bios password clean.

Will try tomoz.

Thanks once again guy's

Im quite sure you would know, but there was a place opposite hamriyan centre in deira which sold electric components - quite a handy shop i tell you, but this was like 5-6 years ago when i was a D&T student.

Shak, Ive got one word for you. . .ROLA !

Rola area in Sharjah, these people have everything. Youre most probably going to find the resistors and serial but not sure about the zender diodes. Plenty of electronic shops around, take a right on the Sharjah Rotana Hotel R/A then a first right. Take an oxygen mask, I'm serious !

Thanks bro I will send my driver this week if not I am going back home to the UK in 2 weeks time I will bring loads of electronic bits back.
Thanks once again

Anytime man!
