Sorry, you will kill the laptop instead.
I've got first hand experience with that.
Get HP/Compaq to change for you. For one reason or another,
HP/Compaq hardware and software are extremely sensitive to changes.
Done wrongly, there goes the laptop. Done correctly, it goes
too.
Partly it's due to the way HP/Compaq sets things. One would wonder
why they do things certain way.
