If you forget the power-on password, the computer must be reset at an HP-certified repair center. Please contact HP to schedule a repair. The Drive Lock password cannot be reset. If you lose or forget the Drive Lock password, the hard drive must be replaced. Please contact HP to order a new hard drive. These services are not covered by the warranty.

i,

To reset the bios password on your laptop, you will need to remove the cmos battery on your laptop for some minutes and insert back, the cmos battery is located on the motherboard of your laptop, once the cmos battery is removed from the motherboard for some minutes, the bios password will be reset, and that fix the problem.

To reset the BIOS password read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Hie there i have installed and reinstall Win 7 Ultimate on Multiple Compaq 610's without any problem.
i once encountered a prob like this one but was lazy so i removed my Hdd and formatted it elsewhere and Walaa my prob was gone. i didn't have to upgrade or downgrade my bios and am still using the same laptop 2day. Just make sure you DVD rom aint damaged.
good luck

Open MyComputer and look for the icon.
Check to see if it is listed in device manager, if not it may not be enabled in the BIOS or you may need to reload the driver for the device.
You can also contact hp.com and chat live with a technician who may be able to help.

Good luck, I gope this helps.
Have a nice day.
