Sorry billy, but you are incorrect. Laptop processors are most definitely upgradeable and I have upgraded previous HP laptop processors without any issues.
To the original poster, please note that upgrading the laptop processor is not easy. It requires virtually a full disassembly of the laptop. There are some cables/connectors inside which are easy to break (i.e. the cables that connect the volume/play controls above the keyboard).
If you really do want to upgrade, I suggest you speak with HP support (use the online chat) to confirm that the processor you wish to use is compatible with the motherboard. Then, you need to obtain a copy of the HDX service manual (do a Google search - it should be available online). This manual explains the exact steps to disassemble the laptop in the correct order to get to the CPU.
Note that it is very important that in addition to replacing the CPU, that you also clean the heatsync (the metal item that is directly in contact with the CPU) and re-apply NEW thermal paste so that the new CPU transfers heat effectively and does not overheat.
If you don't know what I'm talking about or if this sounds too scary (you really could break your laptop beyond repair if you don't know what you're doing) then I suggest you not do this upgrade. But, it IS possible if you really want to do it. Good luck!
