I have a laptop but forgot the BIOS password. I cannot go beyond the BIOS password screen and need to continue.
Is there any way I can reset or even remove the BIOS password on my laptop?

Plug out all batteries, and the adapter, and remove the RTC battery that supplies power to the CMOS BIOS (according to the service manual p59, it's quite easy).
After about 10 minutes, the BIOS will be reset... along with the password.
To dismantle the dv5, I refer you to the HP dv5 Hardware and Service Manual.

On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete
Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete
