SOURCE: jumper settings

There is no jumper settings, it is just a small bridge aside the bios Chip. you bridge the two pins and power to reset cmos.

A much easier way is removing the Cmos coin shaped battery from motherboar for few seconds, and put it back, this will reset Cmos the same .

SOURCE: Toshiba 2455- s306 How do you reset bios and the

That's not a good sign. If you partially flashed the BIOS, you might have a serious issue on your hands...There are some instructions on this site which tell how to try clearing the BIOS, but if it's erased then that might not fix your problem. Follow the instructions for shorting out the BIOS, rather than removing your battery as I can see that hasn't solved your problem.

If that doesn't work, you might have to try to rescue your bios. You can find the BIOS update for your system here (if that site doesn't work, go to>support>consumer products>Tech Support (under Laptops), and enter your model number in the search box (2455-S306)). Go to downloads and find the BIOS update 1.50. Download the .exe and extract it. Try viewing the readme to see if it gives you any useful information. It should also give you information on how to burn the file to a bootable disk, just like you had done with your last one. Try booting that and seeing if that updates your BIOS and makes it readable again.

You can also try some of the suggestions on this page. I'm not sure which version your BIOS is (phoenix, AMI, award), but I believe it's a Phoenix (all our toshibas are). Try some of the instructions in there (obviously replacing files as necessary with the appropriate ones). It looks like you can put the BIOS file you download from toshiba on a USB drive, then use either Fn+f or Fn+b to convince the computer to boot the USB drive and update the bios.

If that doesn't work, you can still save your data. You can pull out your harddrive and (using something similar to this) plug it into a working computer, and copy everything off of it to a folder.

I was a little concerned about your computer being "bricked" and need repairs, but it looks like people have come back from this before, so you just might be in luck. Try the suggestions I've given and if you need further clarification/help or are confused about any of the instructions, let me know what you've done and how far you are and I can try to walk you through the rest.

How do i find the bios jumpers on my laptop

Generally speaking laptops DON'T HAVE BIOS jumpers. Most just have a 'RESET BIOS SETTINGS' control in the BIOS menu itself. Obviously the system calendar clock and some other settings are reset by removing the CMOS battery which is a coin sized battery connected to the motherboard (sometimes mounted in a socket). SOME laptops DO HAVE a bank of mini-switches mounted on the motherboard, such as a SONY VAIO FX702. Your CMOS battery is an NiMH rechargeable type which is low maintenance, shouldn't need changing generally. This is from your manual:

In case nothing worked to reset BIOS password (taking battery out, reseting jumper J1) you can use thrid party software from Hiren's Boot CD to reset the password. You've got Kill CMOS on there, for example which wipes out CMOS. Here's the download link to the entire CD:
