CPU Upgrade

[Mavvelous]

What are compatable CPUs for HP Elitebook 840 G4 except those ones: Intel Core i7-7600U, i7-7500U, i5-7300U, i5-7200U, i3-7100U? These are quite old, and I would like to have something newer.

Notebook processors are integral parts of the motherboard and cannot be upgraded and have been that way since the Intel 5th generation core processors were introduced to market.

The only way to upgrade the processor would be to replace the motherboard and there aren't any supported motherboards that come with anything better than the i7-7600U

Thank you Paul!

You're very welcome.

If you wanted to upgrade the processor to install W11, and if you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2/22H3.

You have to use the version of the Rufus utility that I zipped up and attached in the discussion (v3.18).

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.

There are no other compatible processors.

That is because the system board uses a soldered on (integrated) processor, not a socketed one.

From the Maintenance & Service guide for your laptop. Illustrated parts catalog section on page 19.
