Hey guys...im a poor poor student and this is really not helping me.

I have an old school Toshiba Satellite 300cds Lap Top... The problem is that i was with out a charger for ages,,, and now that i have one i can not for the life of me remember the BIOS password....
I have tried windows cd's and what not,,, but nothinig was happening.. I called Toshiba and they said i will have to wait3 weeks and it will cost me £60+. They said "The password is deep inside the lap top and only we can get it out" I think they are chatting crap...

Has this happened to any one before or am i the only twat out there,

Can any one help me out there please,,, Im really stuck.

Thank a million every one...

Try this - I found it a while ago when a mate had the same problem with a Tosh (Don't think it was the same model tho)

This is what you need:

1. Your notebook
2. An empty formatted diskette (720 kb or 1,44 mb)
3. A second computer (e.g. a DOS desktop PC)
4. A hex-editor (e.g. Norton DiskEdit or HexWorks)

This is what you have to do:

1. Start the desktop PC and start the hex-editor
2. Put the disk in drive A:
3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00
4. Save it! Now you have a KEYDISK
5. Remove the disk from drive A:
6. Put the disk in the notebook drive
7. Start the notebook in Boot Mode (push the reset button)
8. Press Enter when asked for Password:
9. You will be asked to Set Password again. Press Y and Enter.
10. You now see the BIOS configuration where you can set a new password.

And that's all !!!!!!!!!!!!

ps

I take no responsibility if it goes wrong - like I said, it worked for me.

I seem to remember having this problem a while back with an old Compaq Laptop.

I got over it by removing the bios battery and shorting the contacts.
This cleared the bios back to default settings.

[Turkish G]

Cheers guys... does any1 have anymore help tho please...
still not to sure what to do... any ideas peeps?

cheers

[PhilEnfield]

Did you remove bios battery ?

[Turkish G]

No not yet mate,,,How safe is that,.,,Its not my lap top u see.... Would i just take the bat out or is it like a pc where i have to change the lil plastic cap around...?

cheers mate, thank u for your help.

[PhilEnfield]

assuming the Toshiba has a floppy drive of course.

[Turkish G]

Hey mate that did not work... the lap top boots up into the password screen as soon as... iv put the files on a floppy but no joy.

Any other ideas... where woud the bios batt be.. whats it look like?

How would i go about shorting it....

There must be another way tho... does any1 know how Toshiba do it?

Cheers 4 all ya help guys... we will get there soon.

I'll even send da person who does this a few quid so they can av a :cheers: on me..

You may find the battery socket under the keyboard.

Most laptops save the password in the flash memory so removing the CMOS battery would not do any good.

[Turkish G]

Cheers Van Nugent.. so is there any way i can do this then... Is there any way i can wipe the flash memoery.. or anything i can do.. iv already taken it apart and tried a few things,,, What would the bat look like in a lap top,,,is it the same as a PC'z round one?

Cheers guys...

[Van Nugent]

Normally, the CMOS battery for laptops is the same as the one used for desktops. I don't know how Toshiba laptops work. For some laptops, you can use a "master" password from the laptop makers to override the current password and for others, you'll need to contact technical service folks.

Turkish G

have you had any luck with this yet m8.
Sorry I ain't got back to you as the files I've got are in work and I'm off at the moment.
The CMOS battery for the lappy should be a flat 3 cell (looks like 3 peas in a pod) battery, with 2 wires and small 3 pin connector.

If you don't have any joy by Monday - mail me through my profile and we'll take it from there.

Cheers

[Turkish G]

Hey Mate,,,cheers for ya reply.

I found da lil pea's in a pod thin... i unhooked them and left them for a while...Thinking this would clear the mem.... Its not worked tho, the lap top still ask for the password.

Im out of ideas now m8.... hope u can help.?

Thanks 4 this

[Turkish G]

hey guys any1 else got any ideas? :distrbed:

[Van Nugent]

I said earlier that most laptops save the password in the flash memory so removing the battery doesn't help. You need to use a master password or to contact the customer service.

Did you just try tryping in "Toshiba"? Thats sometimes the master password.

_______________________
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.

RTC's which require external batteries include:



Dallas Semiconductor DS12885S (http://pdfserv.maxim-ic.com/en/ds/DS12885-DS12885T.pdf)
TI benchmarq bq3258S (http://focus.ti.com/lit/ds/symlink/bq3285.pdf)
Motorola MC146818AP
Hitachi HD146818AP
Samsung KS82C6818A
Most RTC chips with integrated batteries can be reset to clear the BIOS password by shorting two pins together for a few seconds.

You will see more than one option for some chips due to testing by various people in the field. Remember to remove power from the system before shorting these pins.

RTC ChipPins Dallas DS1287A
TI benchmarq bp3287AMT (http://focus.ti.com/lit/ds/symlink/bq3287a.pdf)3 (N.C.) and 21 (NC/RCL) Chips & Technologies P82C20612 (GND) and 32 (5V)
-or-
74 (GND) and 75 (5V) OPTi F82C2063 and 26 Dallas Semiconductor DS12887A (http://pdfserv.maxim-ic.com/en/ds/DS12887A.pdf)3 (N.C.) and 21 (RCLR) You should be able to discover how to reset the BIOS password stored in most RTC (Real Time Clock) chips by reading the manufacturers data sheet for that RTC. Some RTC's, like the Dallas DS1287 and TI benchmarq bq3287mt cannot be cleared. The solution to resetting the BIOS password on systems with those RTC's is to purchase a replacement RTC chip. How inconvenient!

Resetting a Toshiba BIOS Password

KeyDisk (http://www.cgsecurity.org/keydisk.exe) will reset the BIOS password on Toshiba laptops.

Most Toshiba laptops can be convinced to boot without their power-on BIOS password by attaching a dongle to the serial port which crosses a number of the pins. The pin out is: Pins 1-5-10 2-11 3-17 4-12 6-16 7-13 8-14 9-15 Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.
