Upgrading RAM and hard drive and warranty voiding

[serir]

I'm a private customer I have bought an used before laptop, i have 8GB RAM and 256 GB SSD - it isn't enough for my work. I have checked in system my RAM's serial number and I bought exactly the same 8GB RAM stick, I have also a  compatible with my laptop 1 TB SSD M.2 NVMe drive that I'd like to mount in my machine.

I don't know if I can perform operation of adding another RAM stick and changing my disk without warranty voiding. I've read that in most laptops consumers are allowed to do this. However I found a specification of my machine where is written

"2 SODIMM
Both slots are accessible/upgradeable by IT or self-maintainers only.
DDR4 PC4 SODIMMS, system runs at 3200
Supports Dual Channel Memory"

I don't know if I can change RAM in my machine or hard drive. I don't understand what this "IT" means since I am private customer that bought second-handedly a laptop. I heard that ProBooks are mainly sold to companies, is it about it?

I use my laptop for work and I don't really can give it to authorized service for a week so they could perform operation that I could do in 15 minutes.

The M.2 2280 solid-state drives, PCIe, NVMe  is compatible.

IT is Internet Technology staff.

If the memory module SoDIMM that you bought is exactly identical, you can plug it in and you should see 16GB installed memory.

It is your laptop so you can do with it what you want because all the risk is your own anyway.

As long as you do not damage the laptop when you upgrade it won't void the warranty if there is one.

If you need to return it for warranty work, make sure that you return it to the configuration it was in when you bought it.  That would mean putting the original storage device in a safe place and not changed in any way until the warranty is expired.

By "used before" do you mean refurbished with a warranty?

It would all depend on who you bought it from. If it is a private seller, if there is a warranty it is likely to be with them, not HP.

It was refurbished, seller even sent certifacate "official hp refurbish program" or something like that. So this part about IT staff was rather about users who got their laptop from company so only specialists of that compamy were allowed to upgrade machine.

So I can upgrade my laptop as long as I don't break anything and warranty doesn't void?

I did say that in my last reply.
