Whats the default power-on password

Laptop ( a135-s2276) is suddenly asking for password on boot.

Here's what happened:

1. I attached a usb-to-serial thing to a usb port. After a few minutes the laptop hanged.. had to do a hard-reset.
2. Started the lappy again.. it didn't. The power-light came on but the screen stayed blank.
3. I waited for a few minutes but by now the touchpad area was burning like crazy, so I turned off the laptop again(hard-reset), removed the battery and let it cool.

Now when I start it again it is asking for some password ?? I can't even go into the bios nor boot with a cd.
I never enabled any super-user password or any power-on password. So I guess its some kind of lame factory password. I tried a few passwords 'Toshiba' , 'BIOS' , 'phoenix' etc but no go

Help!

 

Sometimes if you just hit enter when it asks for a password, it works. Try it and see.

 

thats the first thing I had tried..
It is a phoenix bios btw

 

One thing that I didn't understand was, why should an error on windows should result in a problem in the bios.
Another thing that I didn't understand was why does toshiba's support site shouts "DO NOT USE THIS BIOS WITH WINDOWS XP, use only with winblows pissta". I mean whats the bios got to do with the OS, once its finished loading just pass on to the MBR!

well the worst nightmares have come true.. there is Windows in my bios

beware of phoenix bios.

 

It was still under warranty so i sent it back to Toshiba but I was told that the answer lies underneath the panel that holds the ram. You have to remove the ram and then the plastic film that sticks to the motherboard and then short out one of the chips on the motherboard with a flathead screwdriver by touching on the soldered part where the chip meets the board. I was told the chip would say pad500 or something like that. I looked for it when i got mine back but didn't see a pad500 chip but i did see a series of chips in a row that had 520 or something like that on it. I can't be specific on what chip so touch them all. Not sure if unsoldering one leg of the battery loose helped like one guy on these boards said worked for him but i got the other information from a pretty reliable source.

 

I don't think I want to open it coz of the warranty, and sending it to US is a bit difficult since I am in India..
Anyways I found a a lil trick - keep Fn+b pressed while pressing the power button to switch on the lappy. Now all the lights of the laptop lit up and the power light turns orange. I guess this is the phoenix crisis recovery disk mode. Anybody knows what to do next? I tried copying the bios.rom on a usb-disk but that didn't work..

but btw wuoldn't it be much simpler to just get the password from toshiba? I can't find any contact emali wher I could get help.

Thanks

 

Probably a stupid question but should the main battery be removed first?
and any suggestions for removing plastic film? it seems to stuck pretty firmly and I don't want to mess up.

 

I used tweezers to remove the plastic film.

 

woot!!
I brought this on digg front page

Toshiba will not just give you the bios password, they make you send it to them.
