The power on password is a little harder to break in laptops than desktops and this tip may or may not help. Each computer manufacturer is different in how they set thier systems up. Disassemble the laptop down to the chassis where the RTC battery can be seen in its socket. Make sure that all power is removed from this device and remove the RTC battery. Let the motherboard sit without the battery in it for up to one hour. replace the RTC battery and reassemble the laptop. Do not put the main system battery in just yet, power on only with the AC adapter. Power the laptop up and if it asks for a password, just hit enter, if it still asks you for a password, type in "clear". If it still wants a password, then the only other option is to "short" the two contacts in the battery socket for the RTC battery, using a small wire to jump the positive and negative points in the socket, make sure nothing else is touched or you will Nuke your motherboard. With the battery contacts "shorted" power the motherboard up with the AC adapter, wait approx 1-2 minutes allowing the motherboard to post. Shut the board down, and follow the previos procedures for reassembly and powerup.

Most likely in this case, the damage is to the hard drive or its connection to the motherboard. The CQ series though has a three point screw attachment for the hard drive so Im more inclined to think that the shock of the landing has damaged the read/write head on the hard drive. If you happen to have another hard drive for a laptop, try installing a new drive and run the installation disc and see if it will complete and boot completely....if it will then the problem was the old drive.
