The Lenovo Ideapad 100S is built around a 1.33 GHz quad-core Intel Atom Z3735F processor, with 2GB of RAM. That’s a configuration for light duty and not anything overly demanding. Still, what do you expect for $199.99?

In our tests, we found this notebook up to the basic tasks we asked of it, such as opening multiple browser windows, playing video from a microSD card, and word processing. It would slow down a bit handling very complicated web sites with streaming HD video, but it got the job done.

This laptop uses a 32GB eMMC as its primary storage, which is essentially the same thing as a SD card, except it’s not removable. This means there’s no spinning hard disk, which is nice, but it also means that there’s just not very much storage available. Out of the box, about 15GB of this space is taken up by the operating system. This means that adding capacity through a microSD card or the OneDrive cloud service is almost certainly going to be necessary.

The Ideapad 100S comes with Windows 10 Home. Those who haven’t tried this version yet will find it to be easier to use on a laptop that Windows 8. It’s quite reminiscent of Windows 7, but has some nice new features, like very fast boot times: about 35 seconds, in our tests.

This notebook comes with a free 1-year subscription to Microsoft Office 365 Personal. In addition to giving access to the latest versions of Word, Excel, PowerPoint, Outlook, and more, one terabyte of OneDrive storage is also included. Considering how little built-in storage this computer offers, this is likely to come in very handy. After a year, an annual subscription is $69.99.


The 0.3 megapixel front-facing webcam is usable for video chatting, but it has a resolution of just 640 x 480. Even phones offer better than that.

Battery Life

According to Lenovo, the Ideapad 100S will last for 8 hours on a single charge. On our real world use of this device, we found that to be a realistic claim. This laptop does’t have great performance, but it’s easy on its battery. As for the results from the Powermark synthetic benchmark, our tests show the battery inside Ideapad 100s drains extremely fast if you’re stressing the system with more demanding tasks like video playback and rendering modern games. This is the kind of battery life we’ve come to expect from low-priced laptops that are designed to be “secondary use” or “travel” laptops instead of serving as your main PC.

    I wonder how long it will be, if ever, before dim-witted manufacturers will stop ruining the reputation of netbooks with idiotic penny pinching under specification. This and many other similar machines could be EXCELLENT if available with 4GB RAM and 128GB storage. It would be well worth the small extra cost to have an uncrippled machine running Windows. What a damnable waste!

    Honestly I feel bad for all the unsuspecting users who will buy this. I wonder if you can even run this thing with Windows 10 plus Office on it. my home PC has a windows 10 partition plus a handful of essential software apps and it’s taking up 60GB!

    Well, I don’t have any problems using Windows plus Office on my 8in Windows tablet, using a Bluetooth keyboard (the Logitech K480 is great) and mouse, which packs similar specs (ThinkPad 8, Atom Z3770, 1920×1200, 2gb RAM, 64gb eMMC). Also listening to a Spotify Playlist. While periodically checking Facebook and Reddit. Sometimes, I also connect it through HDMI to my 22″ FHD monitor and work with it without problems.

    Absolutely no problemo. These little things are great for your casual media consumption and light office work.

    I also have no problems compiling small (<4000 lines) code on Codeblocks, and running it (it doesn't like when I forget to free some unused allegro sprites, though). It also plays pretty fine on its own, given its a highly optimized engine (like Source), old (like 2d Fallout series) or streamed from a main rig (I played Fallout 4 from it without issues for a while, streaming from my PC).

    Don't pre judge. Although I'd prefer a touch tablet or hybrid at this price tag and size (like Asus Transformer, which also comes with a 500gb HDD and USB 3.0), these little machines are quite fine, nothing like the first batch of Atom netbooks from years ago.
