Short summary and likely causes: the symptom described by — a pre-boot password prompt that immediately erases typed input or keeps reinserting an earlier wrong string — most often comes from either a hardware input fault (a stuck/backspacing key or short on the laptop keyboard or its ribbon) or a firmware-level supervisor (BIOS) lock stored in protected non-volatile memory. As asked, confirming that the prompt appears before Windows loads is the key first distinction: pre-boot means BIOS-level.

Helpful diagnostic pathway (isolates cause without guessing):

  • Remove all USB/peripheral devices so nothing external can inject keystrokes.
  • Use a known-good USB keyboard at the password prompt. If the USB keyboard types normally, the internal keyboard is at fault.
  • If comfortable with basic disassembly and outside any warranty period, power down, remove main battery/power, and temporarily disconnect the internal keyboard ribbon; reboot and test with only a USB keyboard. A stopped auto-backspace after disconnecting the internal keyboard confirms a failed keyboard or short. (Observe ESD and warranty cautions.)

Clarifications and cautions: suggestions to clear CMOS by removing the small battery are often suggested for desktop PCs, but many laptop manufacturers (including many Toshiba Satellite models) keep BIOS supervisor passwords in protected EEPROM or the embedded controller, so a simple CMOS battery pull usually will not clear a laptop BIOS password. That means a persistent password with no keyboard faults will usually require an official service reset.

If diagnostics point to a firmware lock, the safe route is an authorized Toshiba service center or official support with proof of ownership — they can produce a service unlock or reflash the correct NVRAM. Offers from anonymous forum posters or “master password” generators should be treated with caution. The quickest triage is isolation: external keyboard vs internal keyboard; that result determines whether this is a cheap keyboard fix or a service-level BIOS reset.

It backspaces and re-enters same bio wrong password I accidently entered in first place. What I meant. If I can get it to backspace..thing has stubborn mind of its own..it reenters the password I got wrong in first place over and over..wont let me put in right bios password.

What are you trying to say? That your computer cleans up the password a you are typing it?

Just a quick clarification, please. When you talk about typing in this password, when does it ask you for it? If it asks you for a password almost immediately after you turn the laptop on, before windows begins loading, then that may be a BIOS password. But, if it is asking you for a password to log into Windows, then that is a Windows password. Could you just confirm which password you are having a problem with, please? A Windows password or a BIOS password?

If I didn't ask my question above in a clear manner, could you in general terms, tell us what appears on the screen from the moment you turn on the laptop, please?

You can easily remove or reset the bios password. The most easiest way to reset the bios password is. Firstly you need turn-off your computer properly then open the cover of the cabinet of your computer then just go to motherboard and remove the cmos battary for some time and after that insert the cmos battry again. After that you can easily reset the password of the bios.
