    Business laptop first and gaming bonus my friend :)

    It’s a pretty nice looking display for sure

    Hey BoB, first of all, thanks for all the info. I watched all your videos and I found all the information I wanted on this laptop.

    In the end, would you still recommend it?

    I am looking for a thin and light with a good GPU (1050 is the minimum) and with touch. The Surface Book 2 is way too expensive for me, and I am not considering the XPS 2 in 1 because of the lack of ports.

    The way I see, my options are:

    1. Ideapad 720s (lacks HDMI and I'm a bit concerned with the power throttle... also, touch version makes me wonder about battery life and is a little on the expensive side)
    2. Yoga 730 (no numpad, 1050 is not the Ti and WTF with the 51.5Wh battery? didn't find a review on its battery life with such a small battery)
    2. Spectre X360 15t with Vega (the only thing I dislike about this is the AMD card. With a 1050 ti, this would be the perfect laptop)
    3. Zenbook Pro (no numpad, really poor thermals, but appears to have better battery life than the 720s)

    Thank you very much again!

    I think the i7 version of this is a great machine if priced right. If Lenovo let the CPU rip it would be louder too so I’ll give them that, and only that for doing such a thing.

    I never noticed the performance hit with the i7 but the i5 was a no go. I was cpu starved in many titles and it’ll only get worse over time as software becomes more core dependent.

    Is it possible that the power supply circuitry is actually throttling because of its temperature, like the Dell XPS does?
    Just asking because in your videos you said that the power consumption at the wall starts at 90 or something and then drop to 60s. If you see notebookcheck's reviews usually laptops with this config draw between 80-100W when playing games, which means that after an undervolt on both the CPU and the GPU it really should be 90W or even less, which we know that the power source and the power circuitry is capable of delivering, even if not for long.

    Question is, has anyone tried to do something similiar to the XPS mods on this bad boi?

    I'm not sure of the mods you speak of, but for fun a tried an official Lenovo 170w brick. The PSU did nothing to resolve the issue not that I expected it to, but people would have asked if I didn't test it.

    Great laptop otherwise :)

    basically he put some small dissipators on the FETs and redirected some airflow to it

    Really does seem like a almost perfect laptop indeed, they just had to cheap out on that :|

    With the throttling issue would you still recommend the i7 version of the Lenovo over the XPS 15 9560? I want to use the laptop mainly for video editing on the road (large battery important for this). I mainly use Davinci Resolve for editing and colour correction (70% of use). and the rest of my use is mainly Fusion with some work in Maya and Blender. Ideally I would want 32gb ram - do you know if the Lenovo can be upgraded to 32gb ram?

    Would you still recommend the Lenovo i7 version for what I want? Or should I go withe the XPS 15 9560? There does not seem to be many other choices if I want a large battery in a slim form factor with minimum of 1050 graphics for the price.

    Ok so the i7 still has the power throttling but having 8 threads can mask the issue in CPU intensive applications. Just don't expect full frequency at max load, obviously.

    DDR4 can be purchased in 16gb dimms and there's two slots total. These all ship in dual channel so you will have to remove both stick and replace them with two 16gb sticks.

    I have the i7 version, and whenever I run Dota 2 (which is cpu intensive along with gpu) on high settings I keep getting a BSOD WHEA uncorrectable error. I ran Prime95 on itself and it was fine, then FurMark and it was fine, then I ran them at the same time, got the BSOD. Do you think I have a hardware defect and should return it?
