The unit I received is good cosmetic condition. I found only a few spots where the finish is worn, but nothing really too significant to complain about. The laptop booted right up and went into set-up mode. After the initial set-up I noticed that the screen brightness was not adjustable. The brightness slider would go up and down but the intensity stayed constant at a rather dim setting. After numerous Windows updates this brightness issue persisted. In the set-up window there is a pull-down labeled something like “Other Updates” where I found numerous Intel driver updates, one of them being a display driver update. This is the one you want to use because it corrected the brightness slider issue. Now the brightness is adjustable from low to very high intensity. The laptop boots up quickly and runs quietly and only gets slightly warm to the touch once you get your power profiles set. The CPU temperatures rarely get above 90F even while number crunching a real-time Planetary Orbit Calculator I use often. The next test will be running a Software Defined Radio front-end that is FFT intense to decode radio signals for audio listening. I will report back if I encounter any issues with this application although I don’t expect any since other Intel I5 based PCs run this software well enough. Now on to the batteries. There are two batteries in the T470s. Bat#1 is to supposed to drain first, then automatic switching lets Bat#2 take over. I have not been able to test the switching feature yet, but I did notice that my laptop has 4 to 5 hours of operating time indicated after a fresh charge. These are supposed to ship with batteries that still have at least 80% capacity remaining, so that would be around 8 or 9 hours of operation. I will update this review when I have more data on my batteries or if other events warrant an update. Overall, I like this laptop and I expect I should get good service from it. If you are looking for the reliability of a Lenovo, and don’t need the latest and greatest, I  would recommend this unit to you.
