|Hi Dizme, |
try holding down the power button for maybe 10 seconds or more, which may power your laptop off.
With technical queries such as this, you should always advise both the make and (full) model number.
When it asks for the password, and you enter, does anything appear on the screen?
If not, you may have a kb problem.
If something appears, but is not accepted, make sure the Caps Lock and Num Lock are correctly set.
Please advise back on progress.
Good Luck - Keep us posted.
