I have a couple of HP d530 desktops which I am about to sell on. They are completely clean apart from the Security System IDs held in BIOS which I can't edit via the F10-on-startup BIOS settings. It flashes up "Property of.." every time you boot, which isn't ideal.
I have found articles suggesting removing the E49 jumper and booting into BIOS, plus the usual stuff of removing battery and hitting reset button, but none of these seem to affect the system IDs.
Anyone know any other tricks?
