    Hey, did any of you guys do a fresh install? Having problem with the Lenovo Energy Management software, on screen displays on fn keys are now not popping up. fn keys still work, just no indication that it did.

    Not a big deal but really more of I just want it to work as before.

    Also when I looked for the energy management software on apps, it's not there. But i did install it for sure and was able to get to the success page.

    Just wondering if any of you guys encountered this issue. Thanks!

    I did a fresh install and deleted all partitions and in the bios switched from RST to AHCI.

    Did that as well but lost on screen displays. Do you know what driver/ software to specifically install to get that up and running again ?

    OSD for volume and brightness works by using the OSD of windows but camera, mic has no OSD anymore.

    Random update:
    This laptop has really grown on me. Battery life is excellent at 8-10 hours, the laptop is cool enough to literally game on my lap, and that 1050Ti is a good match for the 1080P panel. I've reduced the 1050Ti clocks to 1650MHz@900mV to eliminate any chance of throttling, which allows for excellent high-preset performance in everything but Witcher 3 (which runs at 45-55FPS on medium).

    My biggest complaint now is the single USB-A port, as I use a Logitech dongle mouse and cannot plug other things in at the same time. Other quibbles include a slightly slow panel (though to be fair I'm used to a 100Hz X34; this might be standard for 60Hz), that undervokting is necessary for stable clocks (why is the stock setup 1800Mhz?), only 8GB of RAM, and the fact that I paid $1290 instead of a more heavily discounted price.

    Still, I enjoy the overall package and would highly recommend it if discounted and purchased by a techie that is willing to undervolt. You pay a bit of a premium for the battery life and muted aesthetics, but this is a great hybrid work/home laptop.

    I just noticed that the 720S 15 has an 90W adapter and the 720 Yoga 15 has a 135W adapter. Is that a mistake on Lenovo's site?

    Edit: I found Bob's video on the power throttling. It's a shame that Lenovo skimped on the power circuitry, but I lucked out in having the least vulnerable SKU (i7/1080p). I did see my CPU throttle heavily when doing Prime95/Doom4 torture testing and thought it was temps, but I'll have to check again. Regardless, I don't see that heavy throttling in real-world conditions.

    Bob, how does the responsiveness of your 1080P panel compare to other IPS screens? I see blurriness on moving 2D backgrounds but can't tell if it is a 60Hz thing or panel thing.

    The panel in the FHD model I used wasn't great for gaming but had very nice colors. It was a Chi Mei display.

    Thanks again for the wealth of information in your videos and posts, Bob. You're an oasis of useful content in a sea of fluff.

    Edit: Is there a way to check your panel without disassembly?

    Long as it’s enjoyed I’ll keep making vids.

    Download HWinfo64 and click on the “monitor” tab.

    I too have the Chi Mei display. Vibrant but a bit slow.
