It’s convertible notebooks that are hot these days. But ASUS Transformer Book (T100CHI-C1-BK) takes it even further: the screen part detaches from keyboard, meaning you get a true 2-in-1 device at your fingertips. Under the hood the system features Intel Atom processor and 2GB memory sufficient for lightweight use. So why don’t we learn more about this laptop and see if it would be a good choice for you!

Is it fast enough?

There’s a true mobile processor in ASUS Transformer Book (T100CHI-C1-BK). Called Intel Atom Z3775, the chip features a quad-core design and 1.5GHz clock speed. There’s also burst frequency up to 2.4GHz. In benchmarks, the Atom processor is placed between Celerons and Pentiums. So there’s not too much of performance, but for this kind of a hybrid laptop (web surfing, light entertainment etc.) the Atom is sufficient.

The laptop has 2GB LPDDR3 1067MHz on-board memory. You can’t upgrade it, it’s soldered on mainboard. Dealing with 2GB might be problematic if you like to multitask or use heavier programs. Again, for everyday tasks it’s all you need, but if you describe yourself as a power user you know more would be needed.

The storage drive is a 64GB eMMC (embedded MultiMediaCard). It’s like a stripped down solid-state drive, not as fast or durable as a full-blown SSD but still quicker than a mechanical hard drive. There are no extra drives in this model and the eMMC can’t be upgraded so you’ll have to do with the current drive. After Windows install you’re left around 50GB of free space.

Does it have a quality display?

The touch display in ASUS Transformer Book (T100CHI-C1-BK) looks excellent. It is 10.1″ big (small) and resolution is nice 1920×1080 although lower one would do fine, too. The panel type is IPS which many consider a step up from the basic TN type.

The display turns a bit more than 90 degrees, but the specialty of this notebook is detaching screen. You can indeed remove the display part from the keyboard. This will essentially transform the unit into a real tablet. Because of this design, all the components have to be on the screen part, so on laptop mode the computer might feel a bit top heavy.

How about gaming on it?

Hardcore gaming is best left for other laptops. ASUS Transformer Book (T100CHI-C1-BK) features integrated Intel HD (Bay Trail) graphics engine which is unfortunately a very paltry one. Browser games – like those in Facebook such as Farmville – will work fine but many installable games won’t. Some popular Windows titles that are playable on this rig include Sims 4 and Counter-Strike: Go, but most games from 2014 and 2015 will have poor FPS of 20 and well below.

What connections does it have?

There are two micro-USB ports in ASUS Transformer Book (T100CHI-C1-BK). One is USB 3.0 and the other is USB 2.0. Bear in mind both are micro-USB type, you might need a special cable for some of your devices.

Connecting an HD television or desktop display is possible too. The laptop contains a micro-HDMI output. Again, an adapter/special cable could be needed to hook up a monitor.

The notebook features 802.11 a/b/g/n WiFi + Bluetooth 4.0 card for getting network access. RJ-45 port is not there, no space for that, but an USB adapter can fix this problem.

Placing an internal DVD drive in such a small model would be impossible. So, to access and burn discs with this computer you need an external drive. The microSD card reader (up to 64GB) can also be useful with transferring files from certain devices.

Like a true tablet, the ASUS contains two webcams: a front-facing 2MP one and a rear camera with 5MP support.

Miscellaneous things

It’s a breeze to travel with ASUS Transformer Book (T100CHI-C1-BK). The whole unit weighs 2.4 pounds, but the tablet part weighs only half of that. The 2-cell 31Wh battery on the tablet will last around 8 hours, probably more if you dim the screen. Both parts have their own battery and you have to charge them individually.

The detachable keyboard has no backlit keys. Also numeric keypad is missing, there wouldn’t be space for that.

Operating system is Windows 8.1, the 32-bit edition.


ASUS Transformer Book (T100CHI-C1-BK) is officially categorized as a laptop, but it could be under the tablet category as well. Because of the detaching display, you can leave the keyboard part home and go traveling with the screen only. It’s indeed a great choice for people on the go. However, the system isn’t too powerful, it should be mainly used for light tasks such as web surfing and streaming HD content. If you’re fine with that, and want a very portable device, this kind of ASUS should accommodate your needs well.
