This has developed a rogue BIOS password that nobody knows. Does anyone know where the cmos jumper terminals are on this motherboard. I have tried all the backdoor passwords I can find with no luck.

Laptop BIOS passwords are usually stored on a chip to resist resetting by removing power, battery and CMOS battery. Not usually any cmos clear terminals available.

most Toshiba laptops have a jcmos or similar pair of solder connections that can be shorted to clear the bios password.

I have heard it is Phoenix but unable to be sure as the only thing I get is the screen to enter password.I have entered all backdoor passwords I can find with no joy. I am going to strip this down so I can really have a good look at the mobo with a magnifying torch.

the only thing I get is the screen to enter password.

Not a password to get in BIOS then but a password to even start the laptop. as I said earlier this type of password is definitely kept in a separate security chip on the motherboard.

first try TOSHIBA BIOS as a password. Otherwise you are looking for the Solder bead Of the CMOS something like often located located by the nearest Ram Slot or the CMOS battery. Short the Jumper by some small piece of wire or a tweezer, for just 20 seconds.

thanks Fruit Bat /\0/\ it took me all day to find the info online but that is the only thing us old guys have got 'time'. The info says to find JRS2501. I found it and shorted the terminals while booting the laptop. The bios password was cleared. I have now reassembled the laptop and it is working perfectly. Thanks again for help. Howard
