Lenovo ThinkPad P73 / P53 - 9th Gen, Coffee Lake

Hi, I’m a newbie and read already through a lot of forums, to try to find the best laptop for me supporting Win7, but I’m still unsure.

My fav’s are so far the Lenovo P73 or P53. Main reasons for me are the 1x HDD, 2x M.2 slots and the 3840x2160 display.

I’m happy to learn and test things, I just want to avoid buying a laptop, overseeing something and ending up selling the laptop again…

These CPU’s would be available for those models. Has anyone tested them with the drivers from DeathBringer?

Intel Core i7-9750H (6C / 12T, 2.6 / 4.5GHz, 12MB)
Intel Core i7-9850H (6C / 12T, 2.6 / 4.6GHz, 12MB)
Intel Core i9-9880H (8C / 16T, 2.3 / 4.8GHz, 16MB) Just P53
Intel Xeon E-2276M (6C / 12T, 2.8 / 4.7GHz, 12MB)

NVIDIA Quadro RTX 5000 Max-Q
Description shows that it supports this GPU under win7. Is that correct?

I would need to replace this module and would buy an Intel® Dual Band Wireless-AC 8265, which is the latest officially supported by win7

Is there anything else that I should consider first, any feature that wouldn’t work under win7?

If someone knows another laptop working with a similar or better setup working on win7, I’m happy to hear about it. I haven’t found any 10th Generation Comet Lake Laptop that still offers a 2.5" HDD slot and a 3840x2160 display.

And of course, thanks in advance for your helpful comments and hopefully your patience with me.

EDIT: As it is my first post I sadly needed to remove my links

Dell Precision 7530/7730 should also have a 2.5" bay with the smaller battery.

Seems like just the 7730 has got a 3840x2160 display, but I like the setup, thank you.

Have you successfully installed win7 on it, supporting all drivers?

I don’t own a newer Precision than the M6600 and my main laptop is a ThinkPad P50 so I can’t comment on that.
