    I think no matter the product there will always be dissatisfied customers. It doesn't matter the brand, you'll see the same type of woes on the Lenovo forum, the HP forum, the ASUS forum...

    I'm personally satisfied with my 7510 (16GB, i7-6820, M2000M, 4K IGZO, 950 Pro 256GB and 850 EVO 512GB.) I run more graphics type stuff, Adobe CS5, OneCNC, Rhino5, and have no problems. I think Dell's thermal solution makes more sense. Lenovo uses only one heat pipe for both CPU and GPU so if the CPU heats, both fans eventually start up. Doesn't leave much headroom for the GPU. Also you'll have hot air blowing at your peripherals when they're plugged in. I'd agree Dell's solution is not ideal for lap/bed use, but a workstation shouldn't be treated as such....

    Do not be ridiculous, please. You have experienced some software problem and you imagined that hardware is poor.

    You are blind or Lenovo fanboy. Tests are objective: Dell has much better display, so stop arguing with that. It is a fact.

    We can discuss about keyboard or case, because it is about personal preferences. Price, performance, display quality it is measurable, so do not be silly.
    Dell Precision 7510 and 7710 support Ubuntu and Red Hat very well. Unfortunately, I have experienced some issues with Debian and Fedora, so you have to remember that. The reason of all troubles was AMD FirePro driver. Probably Debian and Fedora will work on 7510/7710 with AMD FirePro in the future.

    If you like Ubuntu or Red Hat, you would be fully satisfied. I prefer Debian, but currently use Ubuntu 14.04.3 LTS, my girlfriend uses 15.10. Fortunately, new Ubuntu 16.04 LTS is coming.

    If you would experience low-performance problem under Linux, disable Speed Step and C3 States for CPU in BIOS. Some Linux kernels still does not support Speed Step on Skylake platform. Even with Speed Step disabled, the CPU is cool and the power consumption is acceptable. The full Skylake-specific functions support is added to Linux 4.4 kernel and higher.
    100% precent agree. Dell has better cooling system, display, case etc. It is not ideal, but the best on the market. Maybe next generation of Lenovo workstations will be better.

    Looks like Dell has made the Thunderbolt docking station available as an add on for the 7000 series. Still not available for individual order nor can you buy a TB laptop yet...

    LouieAtienza,

    I'm still waiting for my 7510 (it's delayed for some reason). I read on another forum that once we start using the Quadro GPU, the fans run at full constant speed regardless of the workload. Is this true for your M2000M? I also ordered the M2000M too. Thanks

    Thanks again for the information. My use of Debian is probably more of a personal preference than a requirement. It is also not really fair for me to compare Debian Jessie to 15.10 in terms of stability, as it is probably more similar to 14.04 LTS.

    Out of curiousity which kernel are you using with 14.04 LTS? The stock 4.2.0.27? I did try 4.4.1 with Ubuntu 15.10 but after it didn't help my external display issue just switched back to the stock 4.2 version, which seemed to work fine as far as performance went. Good to know full skylake support is in 4.4, it sounds like a good candidate kernel for Ubuntu 16.04 LTS.

    Also, if you have time would you mind running a `xrandr --listproviders` to see how many outputs are hardwired to the dedicated GPU? My guess is that they all are except for the laptop screen (just like the Lenovo P50) but its not always the case, as we have seen with the Precision 5510.

    That is good info to know.

    Regarding Fedora and Red Hat. Fedora project is sponsored by Red Hat. Fedora features eventually make it into future RHEL releases. I think the reason RHEL is more stable on these systems while the latest Fedora releases not so much, is because RHEL has alot more QA and testing involved since it has paid support licenses and used in many corporate environments serving things like Oracle EBS and its databases, etc.

    Anyway, I think it is cool many of you are using Linux as primary OS for your new Precisions or as a dual boot. I'm curious why though. I use CYGWIN in windows and I'll ssh, or use a VNC ("No Machine" is the VNC I use), or Xming and X11 forwarding through an ssh tunnel. So basically I'm saying I connect from my laptop to the headless RHEL servers using those means I mentioned or I use Oracle client sqlnet and tools in windows (Toad for example) for database admin from my laptop.

    I don't want to sidetrack this thread which is about the 7510, but since we are talking a bit about Linux, I thought I would ask. How are you using Linux from your laptop and for what purpose? Is it because of dislike for Windows? Or is it for a software requirement and Windows isn't an option? One of my senior Oracle DBAs hates windows and is using Ubuntu on his laptop for that reason. Just curious. thanks

    I wouldn't say it's constant speed, though it does ramp up as my workload progresses/increases. I don't find it obtrusive. I hear it, but it's not an annoying whoosh like some other laptops, my M6500 included.

    That said, I don't understand what the fuss is about. These machines will never run whisper quiet. Everyone wants their CPU and GPU to run at full Turbo mode when running intensive apps. Yet nobody wants the fans to keep them cooler so they don't throttle down? I think many people make an assumption that because the fans constantly run, the cooling design must be bad. On the contrary, it's easier to maintain temps with fans that stay on when in Turbo mode, and adjust speed to the temp needs, then to have the fan on, off, on, off. That causes spikes in temps, followed by constant fan cycling on and off at high speed. The heatsinks, heat tubes, and cooling fins are designed as such, and a fan of proper CFM is used to move air through. It would be ideal but impractical to have huge arse heatsinks and fans on everything, but then the laptop gets to bulky and heavy, and the power consumption rises (less battery life.) Engineering is about compromise; what you giveth in one area, you taketh in another...

    Thanks for the reply. That wasn't my point. I have no problem with the fans running and doing what they designed to do as the laptop get warmer. My point was do the fans run full blast once the GPU becomes active regardless of the workload. I do have problem with that and that should be a design flaws. However, you have answered my question with your first paragraph. Thanks.

    Sorry I didn't intend to direct that at you, just in general. That said even when running I do not find them loud or noisy. Buy it's the rare occasion I work in an absolutely quiet environment.
