MY TOSHIBA SATELLITE A105-S4334 THE SCREEN IS BLACK WHEN STARTING LAPTOP. REPACE THE BATTERY, CAN HEAR THE FAN GOING AND THE LAPTOP IS ON.

I am also using toshiba satellite series laptop. I have also facing this "Issue"

I think you have given password for bios, and your system had been shutdown/hibernated after running out of power.

What you have to do is simple

Just type your bios/master password when that black screen appears and press enter (after typing the password).

Then your system will continue booting.

Please do this and post here the result . :)

Do you hear any beeps when you startup the computer?

If you do, these are the error return codes from what is called a POST (Power On System Test) and they are designed for this exact problem, when you might not have a monitor to be able to display the error information.

If you do have a POST error, then if you post the exact sequence of beeps such as: long, short, short, long as this can help us diagnose if it is a video card issue.

Secondly, if you try connecting it to an external monitor do you get an image? If there is an image then we can instantly rule out video card issues and look more at the monitor itself.

I would highly doubt you've encrypted your HDD or boot loader as Jithinjohny has suggested, because it would still display a message asking for your password.

Good luck and post the results!
