Hello.

I want to upgrade my HP EliteBook 8540p CPU and GPU. I figured out that both are upgradeble. I have a Intel Core i5-520M Dual Core Processor so can I upgrade to a Intel Core i7-720QM or 740QM or 820QM or the 840QM (preferably the 840QM). All of these are written on the manual as Quad Core Intel Core i7 Processors. Can I upgrade from a Dual Core i5 to a Quad Core i7 and will it have any BIOS or thermal issues (probably not BIOS issues since they are written on the manuel) ?

I also have a NVIDIA NVS 5100M. I want to upgrade to the ATI FirePro M5800 and which is written on the manual too. It's because the NVIDIA NVS 5100M only supports DirectX 10.1 and the ATI FirePro M5800 supports DirectX 11. So can I upgrade the graphics card too without any BIOS or thermal issues again ?

If it's a light thermal issue I don't really care. But if it is a main issue, well I'll think about it. But if both are written on the manual, I guess there won't be issues but I want to be sure.

Thanks in advance.
