When i turn my d257 acer aspire one on it goes to blue screen asking for a password, or it either goes to a screen that says no boot disk


No Boot disk found - usually indicates the HDD is not located.
so you need to validate the HDD is inserted properly, and locked into the HDD slot. securely,
Blue Screen asking for password, could mean several things,
basically you need with both errors, take to a good Repair Tech and have this looked into... PASSWORD can be either for BIOs or HDD,
or the system went into LOCKED MODE and password is needed to UNLOCK it.

Black screen blue box saying


some one must have put in a boot password to your laptop,
follow this:
When booting up, enter your BIOS setup (usually by pressing the F2 key at the appropriate time).

Locate the BIOS Password section and turn the ON STARTUP password to off. There is no standard setup for BIOS, so I can't give you exact instructions.

If this does not work, try:
remove cell & start your pc you will here beep...beep...beep...

then turn off your pc & restore your cell.Start your pc and
password is removed.

there is a battery on motherboard,a button cell,you can try removing that and start computer, then put it back, bios settings will be lost.
you can also try removing any hardware like ram,if you have two,when system is off,turn on , it will prompt for changes , enter bios and try remove password.

When I turn the laptop on I see the Toshiba screen for just a second and then it instantly goes to this lovely black screen that says password= How this got there I have know idea. Can anyone help?


Dear beanbean,
This "lovely black screen" is a BIOS password screen. This shows up because somebody has set a boot-up password in the BIOS Setup. If you're lucky, the BIOS Setup is still unprotected, and you can access it as follows:
When you turn it on, look for something that says "Press [button] to enter Setup" or "Press [button] to enter Setup Utilities." Press the corresponding button on your keyboard, and you should enter BIOS Setup.

Now two things can happen. Either you are permitted to access Setup, or you are prompted for the password.
If you can access Setup, navigate to the Security tab and clear all set passwords.If not... then you can either reset BIOS by unplugging the computer, taking off the back, and removing the CMOS Battery (unrecommended), or you can call Toshiba support and ask for the master password (Most manufacturers have a master password, which will allow you to access Setup and remove the boot-up password)
Hope this helps,Ericthecmh
