I've had brought to me an old Toshiba 1640C laptop. The owner has forgotten the CMOS/BIOS password (he has provided proof of purchase) so just a case of locatting either the Jumper or removing the CMOS battery yeah?
Well I've had the keybaord out (a feat in itself) and had a good look inside but I can't find anything... Nothing on the Toshiba website and google doesn't come up with much..
Any help would be great - thanks
It's a Tosh, use a password reset parallel loopback - Link the following pins: : 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15 and 18-25.
I used to carry one around in my toolkit all the time, it's essential.

You could try this (http://www.cgsecurity.org/wiki/CmosPwd). I've never used it so I can't vouch for it.
It comes as part of the Windows Ultimate Boot CD (http://www.ubcd4win.com/contents.htm).

superb.. one question about win boot cd.. how is going to boot to the CD if I can't get it past the CMOS password?
It's not. Hence the loopback trick.

another dumb question... It says 1-5-10 ??? whereas the others are 1 to 1 ie. 7 to 13..

Aha, so you spotted my deliberate mistake then :o

It's linking three pins together.

Bloody hate 'em.. It's the third this month.. I must remember to ask them before hand becuase they always take longer than a desktop.

You will only get more and more mate, its the way the market is heading, bog stand joe blogs only buys laptops now days. Heck even i generally just use and buy laptops now it seems, its what i recomment to everyone theyre so much more versatile and easier (well except fixing :)). So start reading up and getting the workshop manuals for them ;)

nope.. the problem was the making the dongle.
I tried an old male DB25 connector but the bloody thing is sealed. I popped to Maplin Electronics to get a single male DB25 connector and they didn't know what I was talking about.. no surprises there.. I next tried running some core wires from terminal to terminatal as indicated but nothing happened.
So no joy..
Maplin part number YQ48C. £1.49. Shedloads in stock online. Should be able to look them up in-store. :)

You're a hero! There's a Maplins just around the corner, quoted that and got one. Will try later and post back :)
Maplins?
A holiday camp?
Or did you mean a Maplin Electronic Supplies shop? ;)

Hope it works though after all the effort, it should do, it's a trick I used a lot on Toshiba laptops.

git :)
Didn't they used to be Tandy?
No, that's Carphone Warehouse you're thinking of there. :)

They didn't used to be Tandy, they bought Tandy.
Unless I've misread what you mean there :)
I know, but for the sake of brevity. :)
PS - They only actually bought Tandy UK.
It's like battle of the pedants with us two ;D

huh??
Didn't work :( I'm going to call this one quits before I spend too much time on it.
I'm not sure if I got the 1-5-10 combination right.. I took two cables from 5, one going to 1 and the other 10.. 1 to 5 to 10.. Was that right?
Doesn't really matter how you connect the three pins together so long as they're actually connected. You could verify this using a multimeter.
