New pc

Antoine Your HP laptop should work fine on Solus. As @Brucehankins pointed out, the specifications are more-or-less vanilla.

The only uncertainty (as you noted in your original post) is the wifi/bluetooth card, which is a RealTek. RealTek wifi drivers can be a problem with Linux. However, and this is an important however, after update Solus runs the 51.5 kernel. That kernel is used in all of the Ubuntu 22.04 LTS releases (including all the Ubuntu flavors and most derivatives) and most of the other LTS distro releases from April. The 5.15 kernel is almost certain to be compatible with laptops and desktops from major OEM's, including HP. So I don't think you need to worry about compatibility with Solus.

If there is a problem, it is going to be with the ISO (5.13) kernel. A USB-to-Ethernet adapter should provide a temporary workaround if needed to connect via Ethernet and install the 5.15 kernel as part of the normal update process.

I would not overthink the problem. The computer you've chosen is a solid, mainstream product from a major OEM. Nothing is 100% certain, but Solus is likely to work.

Antoine i'm not shure to buy this laptop because the colorimetrie of the screen is not good. i don't know witch pc buy.

No laptop is perfect, and sorting out the trade-offs is difficult. I bought a new laptop last February, and I spent hours and hours sorting out the best fit. At my age, NITS (a measure of average screen brightness viewed from a meter) is important. Normal NITS (250 +/- on mid-range laptops) doesn't work for me, and I had to move up a step in price to get a 400 NITS display. I like the screen's brightness, but it comes at a price in battery life. Life is compromise. Just do the best you can within your price range.

The Ideapad you selected looks like an excellent choice. All the components should work with Solus. I hope you enjoy it!

Antoine the wifi will be detect nativelly ?

It should, but nothing is 100% certain.

The card is identified as "Wi-Fi 802.11 ac Bluetooth 5.0" which are established standards, not bleeding edge. Lenovo uses mainstream components, so the chances are close to 100% that the wifi card will work with the Linux 5.15 kernel.

The card should also work with the ISO 5.13 kernel so that you can install Solus and upgrade.

But even if the worst happens -- the necessary wifi driver for that card isn't in the kernel -- I know from your posting on another thread that you know how to install a wifi driver.

Don't overthink.

Antoine on this latptop no ethernet connection ...

You don't need an Ethernet connection on the laptop. Chances are that you will not need to connect via Ethernet, but if you do need to, the solution is simple. Buy a USB-to-Ethernet adapter (cheap, remember, not expensive), plug the adapter into a USB port on your computer, and plug an Ethernet cable into the RJ45 jack on the other end of the adapter.

WetGeek One might even say that's THE problem. If he can't get it onto his computer, none of the rest of this matters much.

Conceptually, yes, I suppose. As a practical matter, no. All he has to do is connect to his router via a USB-to-Ethernet adapter, then install and upgrade. Then he is at 5.15. If he needs to install a specific driver to get his wifi card running under 5.15, he can do that while connected via Ethernet.

USB-to-Ethernet adapters are dirt cheap. The adapter I use to create a wired connection at the railroad (business-side routers, which have wifi disabled) costs $15.

I have yet to meet a laptop that doesn't have Ethernet capabilities, although fewer and fewer have RJ45 jacks. I suppose that it is possible that the Lenovo in question doesn't have Ethernet capabilities, but I doubt it.
