Wireless

Microsoft continues to employ the Marvel AVASTAR network adapters, which have been somewhat of a sore spot over the years. They have made a lot of driver updates though, and I’ve not run into the issues that used to plague these devices. They also have not historically been the fastest network adapters around, usually averaging around 350 Mbps on a SMB file copy.

WiFi Performance - TCP

The Core i5 model hit exactly what I expected, but there was recently a couple of firmware updates for the Surface Book. It seems to have made some big improvements because the Core i7 model is hitting speeds that I’ve never seen out of these cards. By the time I recieved the updated firmware I no longer had the Core i5 model, but I did update the Surface Pro 4’s firmware, and although I didn’t get quite as good of a result, it was still 50 Mbps higher than when it was first tested.

Speakers

The Surface Book continues to make use of two front facing stereo speakers, which are almost invisible in the bezel. I really like the design that Microsoft has gone with. Many Ultrabooks go with downward firing speakers to save space, but because of the Clipboard, Microsoft would not be able to go this route. They have stuck with the same design as the rest of the Surface lineup, and to great effect.

The Surface Book was able to hit about 80 dB(A) playing music, and for a 7.7 mm thick tablet, the sound quality was good, with decent low end response. Any serious listening should still be done through headphones though. I’ve seen a couple of issues raised with the headphone connector on some of the pre-release Surface Books, but the Core i7 model has exhibited no issues at all. Headphones sound great.

Experience - Room For Improvement

I was going to call this section Software, but it’s more than just software. It’s also not all good, but there’s been some news on that front as well.

Let’s get the bad news out of the way first. The Surface Book has not been a 100% trouble free experience. There have been a lot of issues reported, and many that I’ve experienced as well. Let’s start with the reason this review is delayed in the first place. The first unit that I got had a keyboard failure on the second day. Neither the keyboard nor trackpad would function at all, and it was not even detected in Windows. To be fair, this was a pre-production unit, and Microsoft has not seen any other failures of this type when last I checked with them. But I’ve seen other reports of the keyboard not working after the Clipboard is re-attached, and you either need to restart, or remove the Clipboard and try again. This is likely a software issue similar to the Surface Pro where it sometimes needs the keyboard removed and re-attached to get it to function.

Battery life, which I’ve already mentioned, has been poor when the device is in sleep. I’ve also had issues when it is awake though, causing high levels of draw once in a while. This seems to be more of an issue with the dGPU model, but the non-dGPU model was difficult to use for long periods of time with the non-functioning keyboard so it’s difficult to judge that model. Windows Hello can also cause issues with sleep.

There have also been issues with the screen changing hue, and flickering. Luckily these issues have been sorted out with a recent firmware update which installed a new graphics driver. I haven’t noticed them at all since, and they were very annoying before.

Meanwhile out of the box, the Surface Book is set to not switch to tablet mode automatically, nor is it set to prompt you to do this when you detach it. You have to go into the action center and manually enable tablet mode. I thought this was odd, so I changed it to automatically switch and not prompt me. This was a mistake. Randomly, the device would just switch to tablet mode. It seemed to be detecting that it was detached for brief moments and making the switch.

I’ve also seen reports of people unable to detach the top, but that I have not run in to.

The good news is that the firmware update released on November 2 has done a good job on a few of these bugs. Issues that were major problems are gone. I fully expect this to continue, but at the moment, there are still outstanding issues with the Surface Book. Microsoft is hard at work trying to get the other bugs sorted out, and expect more firmware updates soon, but for the time being the software side feels a bit rushed.

With that out of the way, let’s look at the software that is available. Since this is a device from Microsoft, you get zero bloatware installed. Booting the Surface Book has just three pieces of software listed in the Startup section of the task manager: OneDrive, NVIDIA Update, and Surface DTX. OneDrive is pretty self-explanatory, and the NVIDIA Update is not actually updating the drivers, but rather the whitelist which enables the dGPU. The interesting bit is the Surface DTX.

If I had to guess, DTX would stand for Detach Tablet Experience, but that’s a guess. This is the small piece of software which lives in the system tray that actually performs the Clipboard detach. On the non-dGPU models, this is as easy as triggering the muscle wire to unlock, and then notifying you on-screen with a “Ready to Detach” message. When you clip back in, it shows a message of “Attached” so you know you are good to use it as a notebook again.

When you have a Surface Book with a dGPU though, this all changes. The DTX software monitors if the dGPU is in use. If it is, the icon in the system tray changes to let you know. If you try to detach when the dGPU is in use, it will pop up a box letting you know that you can’t detach, and which program needs to be closed to let the dGPU be released. Software doesn’t normally deal with an instant hardware loss, at least nothing like a GPU, so this is a pretty smart way to get around having applications crash when trying to detach the clipboard.

If you want to change which GPU is used for a program, you have a couple of options. You can set the global setting from Auto-Select to either GPU using the NVIDIA Control Panel. This is easiest to find by searching Start for NVIDIA. You can also customize which program opens with which GPU using the Programs tab, just like with any Optimus machine. The final way to choose is to right click the shortcut to the program, and choose “Run with graphics processor” in the right click menu. Anyone who is familiar with Optimus will find nothing out of the ordinary here.

Generally, devices with NVIDIA graphics have the GeForce Experience software installed as well, but Microsoft has chosen not to install this out of the box. You can install this from the web though, and it will give you the features, such as the ability to have the GeForce Experience select the settings for a game to maximize performance versus quality. If you intend to do a lot of gaming, you may want to install this.

For those looking for more information on the Surface Pen, it's the same model as the Surface Pro 4, so rather than re-write the same text, please check that section out.

    Whether the surface book PCMark8 work score is improved by its dGPU?how many scores will be improved compared to w/o dGPU

    The configuration options seem terribly limited. Why can't the SSD options be completely selectable, 128GB-1TB, independent of the amount of RAM or CPU chosen?

    A 12.1" version (with suitably down-rated components as necessary for the smaller form-factor) with USB-C on the tablet would be tempting if priced right.
  • s.yu - Sunday, November 15, 2015 - link

    I never reckoned this would bother someone. Anyone who only needs 8GB of RAM shouldn't need any more than 256GB of SSD, and anyone who needs 16GB of RAM shouldn't need less than 256GB of SSD, should be the norm.

    But the real reason should be to prevent people getting 16GB/128GB and swapping out the SSD by themselves ;)

    This doesn't seem possible now, but should be possible in the future with more SSD models released, also in "free" markets like China they'll be available on the web when spare parts are abundant.

    The problem with the Surface Book's top-heavy tendencies is only partly mitigated by the hinge. We have a couple at work and people who are using them say they're still pretty unstable. I think getting rid of the upper battery and removing the detachment mechanism would have gone a long way in giving the Surface Book better balance. The other problem the hinge design introduces is the gap which means that when the SB is closed, it won't have the benefit of the upper and lower halves of the system acting in a mutually supportive manner to forces accidentally applied to the top or bottom which might result in unintended bending that wouldn't have happened with a better hinge that allows the screen to rest onto the base.

    I really think Microsoft would have a better product in the second generation if they move all the electronics to the base and deepen it somewhat so the motherboard and battery can all fit. They could also recess the keyboard into the base so the tops of the keys are flush. The screen could be made thinner to make up for some of the extra base thickness and the hinge could be redesigned to remove the flaw of it's big gap that not only demonstrates sloppy design, but also is unappealing to the eye. A good target for Microsoft to model their computer after would be the Latitude e6440 laptop which is a lot more capable, suffers none of the balance problems, and has a very nice keyboard, but I don't think MS would be able to offer it at a competitive price point. The existing SB cost is extremely high for the given hardware and ought to be lower given the flawed hinge and poor design decision with the raised keyboard.

    You're absolutely right about those two issues. But since this still is a Surface, MS will have to make it part tablet no matter what, IMO.

    Instability in the lap is still reported occasionally in reviews, no doubt due to the top-heavy construction, and as I said before, they should use lithium alloy like Lavie Z only in the top portion to deal with this, but some fanboys disagree. Nothing's gonna change the design of their "ultimate laptop"!

    One reviewer made the strangest decision to step onto the hinge with the Book open to see if it held. I think he's just a fanboy trying to deceive people into thinking the design is flawless because no force IRL would be applied that way. If he stood on the middle of the *tablet* section, with the Book *closed*, and the tablet section/Surface connectors still didn't snap, that would answer the question.

    Slowly but surely, the mutation which is a "tablet computer" is evolving back into a regular laptop. Hilarious.
  • chrisnyc75 - Friday, November 13, 2015 - link

    Great review! But I'd like to see it updated with results vs the new Dell XPS 15 (skylake & 960m) rather than last year's Haswell model, at least on the gaming tests if not all of them (though I think it would be an apt comparison point for all of the tests as the XPS 15 is roughly the same size/weight as the Surface Book, and prominently features 4k touch-screen as a primary feature, even if it's not actually a 2-in-1. A lot of people are still going to see the XPS 15 (not just the 13) as a direct alternative to the Surface Book)
  • s.yu - Sunday, November 15, 2015 - link

    1. I don't think it supports pen input. Short as the battery life on the clipboard is it's useful for note taking.
    2.It's still noticably bigger, and...does it still have that big battery option from the old model? Otherwise the battery would be really small.
  • chrisnyc75 - Sunday, November 15, 2015 - link

    All good questions, and exactly why I'd like to see the XPS15 added to the comparison. Sure, the SB detaches, which can be useful, but the very existence of the Surface Book is owed to the fact that tablet sales have been in rapid decline across the market. Putting that bit aside (which I realize is missing the whole point of the Surface Book), they're almost exactly the same size & weight, both ~4k resolution, both touchscreens, & both Skylake + nvidia dgpu. As long as you're only pitting the SB against other detachable devices, it's ALWAYS going to come out on top because MS hit a home run with that part....but does anybody care? Enough to overlook a cheaper option (Surface Pro) or one with more power (XPS)? I personally would like to see the nitty-gritty comparison of the two before I decide.
