Good review, well done. Do you know if a touch screen is available (people at the law firm are only interested in laptops that have a touch screen), and does that limit the resolutions available? Thx.

Thank you. Touch is available but only FHD screen option(300 nit).

I had the chance to look at a T590. While I had a string of T series ThinkPads years ago, starting with a T20, I have mostly used desktops for the past several years, so it was good to catchup with the latest generation T-series.
The 15.6" FHD display is gorgeous - color, contrast, clarity, everything just right. The only issue I have with a X1 Carbon Gen 3, is that I can not get the contrast just right. No issues with this non-touch display (Lenovo LEN40BA, Innolux N156HCA-EAB, IPS, max res. 1920 x 1080), it's perfect out of the box. And while the 14" display is a good size if you're going through airports and on a plane often as I once did, the 15.5" may be a better size if it's just office and home. If I wanted to use this instead of my desktop, it would be would not be difficult for me to switch. Other display options will be: 15.6" FHD (1920 x 1080, 250 nits) IPS Multi-touch, and later, 15.6" WQHD 4k (3840 x 2160, 500 nits) IPS with Dolby Vision HDR.
The battery on this larger model is 57 Wh with 55.5 Wh available. The other specs, ports and features are the same as the T490 above. I also noticed the manual shutter for the camera (I had not seen that before), which is a nice security feature. Here are some relevant photos:
PassMark system benchmark. It warned that with G-Sync enabled, frame rates in the 3D tests using MX250 are limited to under 60 FPS (this display is 60 Hz), affecting that score. There is no easy way to enable/disable G-Sync, as the Nvidia control panel does not provide the option, and this test score is with it enabled.

Could you please run Cinebench R15 Multi for 3-5 times to see how the system handles CPU heating over time? Would be really great!
Edit: Do you also know if the CPU is cooled by 1 or 2 heatpipes?

Integrated graphics models have a single heatpipe, while discrete graphics models (this model) have two.
I ran 5 passes of Cinebench R15.0 CPU in a row, the best result was the first run with a 636 score. Here are the relevent snips:

Bear in mind, this is an early sample and drivers are far from final. More importantly, monitoring all the sensors with HWiFO64 takes away from a CPU benchmark score. Single runs without it produced scores 670 and above, with 673 being the best:

Okay, I didn't know that the effects are so large. With undervolting the score might even be more impressive. However, you need the dGPU model, the Intel GPU model might be much worse due to the single heat pipe. I'm currently deciding between t480s, t490s or t490, and a dgpu is not really needed. Do you know if the tb3 port is a full 4 lane port?
Again thank you very much for your help!

Could you be so kind as to take a quick look in Settings/Display/Advanced Display Settings to see if the T490 and T590 machines will actually display in a 8-bit color depth. Both of the T480s models I have only display in a 6-bit color depth, so I am looking to see if the T490 or T490s models will actually display in 8-bit.
Thank you for your time and for the nice review
