You'd have to replace it with the original driver (a quick search revealed no part numbers). Good luck finding one for a reasonable price in relation to the value of the HP's. How long have you had them? They should come w/ a years worth of warranty. If they're older than a year, then my advice would be to buy a new pair. You could try disassembling them, getting the number off the driver and looking for it. But if you replace it w/ a cheap substitute you'll regret it.
Remember my advice is worth what you paid.
