Surfacebook – Dock and Loud Fan


Hello All!


I have a surfacebook.  By chance does anyone else have issues where you are randomly getting a loud fan with nothing going on CPU wise on the device?  After about 5 minutes it clears?

Second to that, anyone use the dock daily have issues where you have to powercycle it after coming out of sleep in order for it to recognise the NIC, USB Devices and the monitor?

    I don't have a dock so no issues related to that but mine has randomly spun up when I wasn't doing anything to warrant that, less that a handful of times all since Anniversary.

    Yes, I still have issues with this too.


    The biggest one is I still have crashes during sleep when its connected to the dock.


    The monitor every so often I have to unplug the dock and plug it back in to get that to kick on. Super annoying. Every firmware update I think they've maybe finally fixed it, but nope.

    I have the same issue with the fan. I've tracked it down to only happening when on mains power and not battery. There is high CPU usage from the System processes. 

    Digging a bit further I think it's APCI.sys process.

    I too also have problems with the machine crashing when docked and coming out of sleep. It's a real pain as it's my main machine and I often have files open when this happens.

    I have seen this also and during high cpu usuage task manager shows "Windows error reporting" distroying the cpu.

    Still investigating..

    I dock the Surface Book daily at work and never had those issues.  However, there were times that I would have a blank screen and have to perform a hard reset.  The most recent issue I've been experiencing is the detach -> attach cycle whenever I adjust the angle of the SB's display.

      I had the same issues regarding the blank screen.  As of late, starting with that "borked" patch, I now have my nic drop everytime I coume out of screen saver or sleep.  I have to power cycle the dock.  I'm nearly at the point of throwing the damn thing.

      What is your monitor setup?  For instance I run a 21:9 wide screen which has a higher resolution then just a single 1080p.  Also had the issue when running a 4k monitor as well.

      When it does this I also notice video stutters, or anything graphics related in the browser.  I'm wondering if it's video card related.

      I have two monitor setups as I have two offices on campus where I work: 1) A single Dell U3415W monitor and 2) Two Dell U2414H monitors.  Initially, I had trouble with the two Dell U2414H monitors because I used DisplayPort chaining and they were horribly unreliable.  After reading through forums, I had the two monitors replaced with a newer version and never had an issue with them.  I've never tried hooking it up to a 4K monitor, but my department just received the Surface Hub so I'll be hooking it up to that soon.

      When the Surface Book is hooked up to an external monitor, I've sometimes experienced slow, I mean SLOW video playback especially on YouTube.  I tried various browsers and they all had the same issue.  I suspect that it is related to graphics and I just reboot to fix the issue.  I'm not sure what's the cause of this behavior, but it's annoying to say the least.

    I have this same issue on my seems to happen frequently for me when I close the lid.

      If it's docked and the lid is closed, it wouldn't surprise me if the heat dissipation is poor then. Convection should carry heat away from the CPU when it's open, but when it's closed that heat has nowhere to go, and doubly so with the dGPU, whose vents are covered by the screen.
