what is upgradeable in a hp envy laptop ?

Most laptops allow the user to upgrade their RAM or memory by adding a stick to a compartment in the computer At HP®, most of our laptops have been designed so the user can open the unit with a Phillips screwdriver and add new or upgrade computer memory with relative ease.

Probably just the Hard Drive and RAM.

The Envy is a class of laptops, not a single model.  As such what is upgradable in them is going to very by model.  

But normally with a laptop, the process and the graphic card are chips build right into the system board.  You can not upgrade either of them.  The hard drive and the RAM memory are separate and can be upgraded.

Beyond that, you would have to look at the specific model to determine if anything else is updateable.  But normally those four (processor, memory, graphics and hard drive) are the tings that you would want to upgrade.

depends on the model.  frequently only the RAM and HDD ... or an SSD can be substituted for the HDD

The only major things you can upgrade on a laptop are usually just the RAM and hard drives not much else.

Laptop upgrades are limited by the space inside the unit and the ability of the fan to cool the unit.  (some upgrades will create more "heat" and cause the fan to be unable to properly keep the unit cool.)  The cooling problem can be resolved by using an additional outside source for cooling the laptop.

You should be able to upgrade almost anything as long as you are finding parts that are compatible with the space inside your laptop.  

Basically, you can upgrade almost anything that already exists inside the unit - but it would be hard to add anything that wasn't already in there.
