Surface Book 3 as a desktop replacement


So I recently bought a Surface Book 3 to use mainly as a desktop replacement connected to an external monitor at my home office. Since I won’t be going anywhere anytime soon I was wondering how to keep the device healthy throughout the period.

  1. Is it safe to keep the device closed during office tasks like email, Word and web browsing? I know that Surface Books have a vent above the keyboard for the GPU, but since during office work the Nvidia GPU is inactive, it should be fine? Right?:)
  2. There is an option in the UEFI to limit the battery charge to 50%, but it works only for the tablet part. The base still charges to 100% every time. Are there any good practices I should follow? Discharge the battery (use it for some time) every week, month? I’ve seen horror stories of swollen batteries on Reddit and would like to avoid it if possible.

Any help is much appreciated.

    I only have a SB2 but think would be fine operating 'closed'. The infamous 'hinge gap' is a win here. If anywhere nearby I suspect the fan noise will be sufficient to alert you if it's getting hot. They add a very realistic additional wind rush sound effect when running Flight Sim 2020 on mine :)

    Powershell gives access to a very comprehensive history if you want to keep an eye on it

    powercfg /batteryreport

    This is my SB2, was new in 03-2018

    I just use it, but have heard keeping batteries between 20-80% is better than full cycle charge/discharge

    The battery is probably the biggest issue. This article on Windows Central is a pretty good rundown.

    I worked like this for several years with a Surface Book 2. While its certainly OK to run it with the laptop closed, I actually preferred to leave it open with the screen on. I'd start Outlook and put that on the Surface screen, and then do my actual work on the big monitor. If you set up the Display Options for the correct screen placements, it makes the mouse movement fluid.

    As far as battery health, I would undock on the evenings and browse content, play games etc with it unplugged (on the couch), which ended up cycling the battery. And don't leave it charging overnight, because that stresses the battery the most.

    If a battery is going to be an issue... Why are you using a portable as a desktop? To me it seems counterintuitive. If you need minimal desk space, there are many small-footprint PCs. From the Intel NUC, to the Mac mini, to multiple Ryzen-powered nano-ITX systems. If you care about power-to-size ratio, all of these machines will do better. All of them have lower thermal constraints, no worry about batteries, and overall will give you better long-term performance than a convertible in docked-mode.

    I'm not insulting the Surface Book, it's a fantastic machine for portable computing, but remember that even a basic Skull Canyon NUC will offer better thermals. Even space-constrained compact desktop systems will have less thermal issues than high-performance portables.

    From your situation it seems like you need a good quality desktop system. Build up a Skull Canyon NUC, or grab a Mac mini and then buy a used Thinkpad for portable work. I think you'll get something better for both use cases.

    SB2 owner here. I think you'd be okay as long as you are cycling the battery at least every couple of days rather than allowing it to stay fully charged all the time. Mine has held up well doing this. My workflow is working at my desk during the day with it docked. Undock and use it for casual use/reading in the recliner in the evening. Unless it is absolutely discharged, I leave it off the charger until morning.

    One suggestion, if you don't need the base and you're not interested in actively using the tablet screen, why not just disconnect the base from the tablet. You can charge the base where you need it to preserve the battery and then disconnect it. Just dock the tablet.

    Original Surface Book owner here. Surface Book used primarily as desktop replacement with the Microsoft dock. After 3 years of use the battery under the keyboard bulged so bad the bottom cover came loose. Replaced it with a Thinkpad. Probably would not buy another Surface Book.
