Just FYI: Should you plan on using Linux on the T490 don't get the Nvidia version. Read the forums, battery life drops to 2-5h vs. 9-11h on Windows.

I hope the next generation fixes this and/or we finally get good nvidia drivers.

Give Pop_OS[1] a shot, it lets you switch between iGPU and dGPU.

Been using it on my Thinkpad P1 works well for my workflow, I almost always use the iGPU and for tasks that need dGPU

I am usually plugged into power. I get good battery life this way.

But I agree, MX250 option isn't worth it for the amount of GPU power it gives and the complications it brings under Linux.

GPU offloading is being worked on by nvidia[2] so there is indeed hope.

Thanks but Pop_OS also doesn't help here. They did something different for the T490. My colleague has a T480 and that works fine. T490 also doesn't have a BIOS/UEFI option to disable the NVidia (again there's forum threads requesting that as well on the Lenovo forums).

The problem is that the NVidia card never enters its high power saving states even when it's disabled.

I lose about 20% battery on standby overnight.
