Question about HP 530 Notebook PC
Every system must store the BIOS password information somewhere. If you
are able to access the machine after it has been booted successfully,
you may be able to view the BIOS password. You must know the memory
address where the BIOS password is stored, and the format in which the
BIOS password is stored. Or, you must have a program that knows these
You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.
!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

SOURCE: how to refix key of hp 530
you may try to put it back again by try it but it seems not work since you post uyour question here.
here is some risk.
Download the product manual from the hp support site.
read the instruction how to remove your laptops keyboard, after remove fix it, and reinstall it again.
but it pretty risky because i suggest you may want to do it with people who had experience with it.
but my first time i do it myself there was no problem at all. just follow the manual instruction.

Check with HP if they have what is called a TPM - trusted platform module. This is a chip that is coming by default on Sony's and a few others. If by chance this is what he applied a password to, Sony will tell you that you have just purchased a very expensive paper weight. The chip must be replaced. This is a last resort of course.
There are many sites that offer "Back Door" passwords which are default for the manufacturers while in production. But sometimes you can get lucky & get one on line.
Another way is to remove the cmos battery for 1/2 at least. This should reset the bios,which then if works go straight to the bios and create a new bios password or none at all.
Some people I know have gotten their pc's to boot with boot software. This is worth checking into. Just remember, it's all about security now with identy theft ect..... So it may not be easy or at worst --- possible.

SOURCE: removing power on password
When you restart your PC, before it boots to windows on the HP logo , tap the F10 key to enter set up, Go to security option and disable to power on option. next time when u restart it would not ask you for a power on password.
