Re: laptop keyboard not working
Random keys or a row of keys not working indicates that the keyboard is failing and needs replacing. Before replacing, you might try taking the keyboard off and cleaning the connection. A little dirt or corrosion built up might cause this, but most likely the keyboard has malfunctioned.

Go into device manager in windows and delete it and reboot. If it comes back when it detects the keyboard and it works then it was a driver, if it does detect it or it wont work correctly then it is a bad keyboard. You can also try a plug in keyboard to see how it behaves, ps keyboards are not that expensive.
When a keyboard stops working, has odd key letters, stuck keys and non-functioning keys for no reason at all, the laptop may have an easy fix solution. However, if liquid spilled on the laptop or the laptop was dropped and as, a consequence, the keyboard doesn't work, or the keyboard device has simply failed, fixing the problem may require a more involved laptop keyboard replacement.

Sometimes dust and debris can cause keys to lock, making such keys non-functional. Disconnect the laptop from the power outlet and remove the battery. Make the tip of a cotton swab as thin as possible by rolling it between your finger tips. Dip the thinned cotton swab in rubbing alcohol and clean the crevices of the keyboard with the cotton swab. Continue cleaning between each key of the keyboard with the alcohol-dipped cotton swab. Use a new cotton swab whenever necessary. Slightly tip up one side of the laptop so dust will move from under the keys to the crevices so you can clean. Blow compressed air into the keyboard again as you did in Step 1 of Section 2. Reconnect the computer to the power and check to see if the issue is resolved. Insert the flat edge of a flat-blade precision screwdriver under a keyboard key and gently pry it up and off. Remember where the keys go, so you can easily replace them. Remove three keys at a time and clean with a cotton swab dipped in alcohol. Replace the keys and remove the next three. Do this until the entire keyboard has been cleaned. Disconnect the laptop from the power outlet and remove the battery again. Turn the computer so the rear is facing you. Remove the screws that hold the plastic hinges in place. Insert a small flat-blade precision screwdriver in the plastic hinge seam and pry the hinges up. Turn the computer back face forward and open the screen as far back as it will go. Continue lifting the plastic hinge and power plate until it comes off. Remove the screws you see holding the keyboard with a precision Phillips screwdriver. Blow compressed air under the keyboard. Lift the cable connector levers slightly and remove the data cable. Clean the cable pins with an alcohol-dipped cotton swab. Replace everything, power on the computer and try the keyboard again to see if the issue is resolved. b> Keyboard Replacement b> Connect an external keyboard to the USB port on the laptop and verify its working condition. Disconnect the external keyboard and verify that the keys on the laptop are still inoperable. Disconnect the laptop from the power outlet and remove the battery.

Can you tell me whether this is a bios power on password, a hard drive lock password, or a windows administrative operating system password? I'm assuming that it is asking for a password when you say "locked".
