Too late now, but....

Flashing the bios is NOT a fix-all !

It's the riskiest thing you can do with a computer !

Never flash your bios when you're not sure whether your computer, or your hard drive and operating system if you're flashing in Windows, is working properly !

Never flash your bios unless you MUST !
The only legitimate reason to flash the bios in most cases is to add support for recognizing a type of cpu that you want to install in the future that your present bios version can't recognize, unless you find specific info in release notes for a bios version newer than your mboard has that it will fix a problem you're having !

When you have the choice of either flashing the bios by using a bootable disk, or by using a flash utility built into the bios, or by using a flash utility in Windows, you should always do it by one of the first two methods, preferably the first one, because things are more likely to go wrong when you do it in Windows.

Even if you use the right bios update and the right flash utility, bios flash chips can only be flashed a small number of times, and the flash chip can physically fail when you attempt to flash the bios, sometimes the FIRST time you try.
.......

You probably no choice except to hold the power button down until the computer shuts off the mboard, then press it again to see what happens.

If you see a "Cmos Checksum Error...." or similar message, and you DO NOT also see "BOOT BLOCK BIOS" or similar on the screen, the flash was successful.
Go into the bios Setup, set the current Date and Time, load Bios Defaults, Save bios settings.
..........

If you DO see a message "BOOT BLOCK BIOS" or similar on the screen, the flash failed, the flash chip has probably not physically failed, and the fail safe Boot Block portion of the bios code is still there - in that case you can do a specific procedure to attempt to flash the bios again.

If you see no message......
- if the laptop has a built in floppy drive, if the led for it comes on while booting like it usually does when there's no disk in it, goes off, then comes on again for a longer time, you can probably do a specific procedure to attempt to flash the bios again, despite the fact you see no video.
......

You could look on the Toshiba web site for trouble shooting info.

Thanks for your reply, finally i do a power off becouse nothing happens.
Now the laptop starts with a Black Screen, nothing more.
I read some info, and some solutions that someone do to others Laptops Brands.

I see that using SB floppy disk with bios old bios file on the diskete and doing a propper key combination when power on, can do some solution.

Maybe i can recover the old bios stored at HDD becouse the program says that a back up was done fine. Here a pic of that.

"Now the laptop starts with a Black Screen, nothing more."

That can indicate the flash chip has physically failed, in which case you CAN'T fix your problem, unless you get a professional to REPLACE the probably soldered into the mboard bios flash chip

OR - that the flash failed but the flash chip is still physically okay.

Does your laptop have a built in floppy drive?

- if the laptop has a built in floppy drive, if the led for it comes on while booting like it usually does when there's no disk in it, goes off, then comes on again for a longer time, you can probably do a specific procedure to attempt to flash the bios again, despite the fact you see no video.
....

If it doesn't have a built in floppy drive....

See the Toshiba web site for failed flash troubleshooting info.

Information about other laptop brands can not be relied on to apply to a Toshiba model.

If you DO try a special procedure to recover the bios or to flash it again
- the procedure CANNOT work if the flash chip has physically failed !
- the Boot Block portion of the bios code must be still there on the flash chip - that part of the bios code is usually NOT replaced when you flash the bios by default because it doesn't need to be replaced.
- you must use the specific recovery or new flash procedure for the brand of bios it has - one of Phoenix, Award, AMI, etc.- and use the RIGHT version of the flash utility.
.......

That image you provided the link to...........
Is that exactly the brand and version of flash utility you saw the screens for ?

"Maybe i can recover the old bios stored at HDD becouse the program says that a back up was done fine."

When you can't boot the computer, the only way you can get that bios backup file is by removing the hard drive and connecting it one way or another to a working computer, but don't boot from it on the other computer (Windows will not fully load fromyour drive if the other mboard is more than a little different).
E.g.
- buy a suitable hard drive enclosure - I recommend a Vantec one - for the type of drive - IDE (PATA) or SATA - and connect it via a USB cable (or via a eSATA cable if the and the enclosure and the computer you connect to has a eSATA port) to another computer
- buy some other type of USB to laptop hard drive adapter
- buy a simple gender adapter - laptop hard drive to desktop drive connection adapter - and connect it internally to a desktop computer's SATA or IDE cable or header

Thanks again Tubesandwires,

I followed some of your sugestions.

My laptop didnt have a built in floppy drive.

I have recovery discs (3 dvds), original from Toshiba, and my HDD have a partition with original Vista home premium that come with computer.

When i Power on trying some key combinations (ex: fn+b+power, fn+f+power, fn+esc+power and plus more combinations) with dvd recovery onto dvd-drive, nothing new happens.
The laptop start, power light indicator and plugged power light indicator are on, as allways. cd drive make tipical sound spining, and the cooler also run, as always, but screen is black.

I Was lookin on the net for exact solution to my model (to restore bios) and its hard to find.
I found some interesting articles to follow applied to similar models of toshiba
one here:

Obviously, you can't install software if the computer will not boot normally.

Optical drives only need the power connector to be connected to them and the computer to be running to:

- open and close the tray and briefly flash the led when there is no disk on the tray.

- spin the disk briefly and turn on the led briefly for a bit longer when a disk is inserted.
