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.

    Surface book has surprisingly good cooling. I did prime95 test myself for 30 mins and CPU clock was around 2.8Ghz. Slightly less than full turbo, but still impressive for 7.7mm thin device. Spectre x360 lasts ~12 hours with 52Wh battery, so it makes sense this HiDPI machine lasts ~12 hours with larger 70Wh battery.

    And face it, anandtech is not really interested in anything non apple. I have recently seen a side-by-side blind test of 6 smartphone cameras and iPhone 6s+ one was very obviously the worst in all possible situations. And AT called iPhone 6s "the best phone ever". LOL.

    This should be the 11th review on the MSB I've read. The battery life varies greatly between reviews and I've seen 4 6-7hrs claim, 2 10-11hrs claim and 5 12-15 hrs claim including this one (in fact the 15hrs it got out of the i5 model is the longest I've read about, it was mostly 12-13hrs). I think it's just that there are still many problems with the software, and if not solved, you could get 2.5hrs minimum just surfing the web (single case of customer feedback) with the keyboard attached.

    Personally i could achieve 9-10hrs with office jobs and chrome, and 14 hrs with edge.

    Any chance of redoing the Surface Pro 4 battery life tests post - firmware upgrade?
  • vinsanity - Tuesday, November 10, 2015 - link

    Which Surface Pro 4 was in these benchmarks??

    I like the Surface Book. I think it's a GREAT laptop. But I won't be buying one because I'm probably not the intended audience. I need my Quad Core CPU.

    The thing that really got my interest was the internal design. No the part where the screen comes off, but the part where the battery is behind the screen. It really was like a eureka moment.

    Microsoft's implementation has it that the batter in the clipboard is high, with a higher center of gravity relative to the hinge. They were forced to do so because they need space for the "muscle wire" mechanism. BUT conventional laptops don't need that mechanism.

    Having all or part of the battery behind the screen is such a brilliant design idea. Especially since LCD panels are extremely thin nowadays. It removes a huge strain on the internal design of a laptop, and leaves more area for active/hybrid cooling and other peripherals, while remaining relatively thin. Not necessarily lighter, but considerably thinner designs with significantly more room for much larger battery (and possibly more circuitry) behind the screen.

    NOW, I want a conventional, thin, high performance laptop with a beefy processor and GPU, and a lid that adds more battery behind the screen towards the bottom (to lower the center of gravity of the lid and make the device more balanced). The lid would be a tiny bit thicker on the bottom and tapers along the top (like a macbook air for the lid only).

    This design would be great for think, stylish mobile workstations and gaming laptops.

    Good review, fair criticisms

    One of the best thing for Surface Book is fast storage. The most powerful notebook this size that is great for League of Legends or Dota 2. Ok for $1899? Give me an Elitebook 14" 745 G3 for $919+ and install $350 PCIE 512GB. $1269. They both are about 3.4 pounds. Can the Elitebook run Dota 2 with twice the storage, Yes.
  • s.yu - Wednesday, November 11, 2015 - link

    That's not very fast. RAID0 gets you twice that speed. Don't forget you could get the bad straw and end up with an even slower drive.

    I don't understand why anyone should be bothered with this because of all the privacy issues. According to our tests it is actually abiding the claims they made by gathering even contents of my disks and uploading them to some ip address held by microsoft.
