The Pros

Long battery life; Attractive design; Good viewing angles; Large keys with solid feedback

The Cons

Keyboard flexes; Touchpad doesn't support gestures


The IdeaPad 100S gives you an attractive chassis, solid performance, free Office 365 and long battery life for under $200.

Just how much laptop can you buy these days for under $200? Starting at $199, the Lenovo IdeaPad 100S is a lightweight, long-lasting Windows 10-powered laptop with a touch of style, good viewing angles and over 9 hours of battery life. Like other systems in this price range, the 11.6-inch 100S offers very modest performance and cuts some corners when it comes to keyboard and touchpad quality. However, if you're willing to live with a few compromises, you can get a very capable secondary computer or child's laptop for a great price.

For a laptop this inexpensive, the Lenovo IdeaPad 100S looks anything but cheap. Available in red, blue, gray or white, Lenovo's low-cost laptop has a classy matte finish that carries the accent color and persists from the lid to the system's bottom. The rubber feet match the color, but the sides and deck are a subtle black color with a similar matte texture, which did a good job of resisting fingerprints.

Lenovo Ideapad 100S Size


2.2 pounds


 11.5 x 7.95 x .69 inches


At 11.5 x 7.95 x .69 inches and 2.2 pounds, the Lenovo IdeaPad 100S felt incredibly light and portable, both in my hands and my bag. The Acer Aspire One Cloudbook 11 is nearly the same size (11.5 x 7.95 x .7 inches), but weighs -.2 pounds more, while the Lenovo 100S Chromebook -- the Chrome OS version of this laptop -- is slightly larger and heavier (11.81 x 8.23 x 0.78 inches, 2.52 pounds). The Asus EeeBook X205TA (11.2 x 7.6 x 0.6, 2.16 pounds) is ever so slightly smaller and lighter, however.

While most Windows PCs come with hard drives or SSDs that have hundreds of gigabytes of capacity, ultralow-cost laptops such as the IdeaPad 100S, HP Stream and Acer One Cloudbook series typically come with 16, 32 or 64GB of eMMC storage memory. The IdeaPad 100S comes with 32GB; 17GB of that is free, with the rest taken up by Windows 10. You can expand the storage by purchasing an inexpensive microSD card, which gives you another 64GB for just $20, or you can use some of the 1TB of cloud storage that comes with the included Office 365 subscription.

Display and Audio

The 11.6-inch, 1366 x 768 display for the IdeaPad 100S isn't as colorful or sharp as those on expensive laptops, but it provides surprisingly good image quality with wide viewing angles. When I watched a trailer for Star Wars: The Force Awakens, I could easily make out fine details like the beads of sweat on Finn's brow. Most colors, including the red in a First Order flag, seemed mostly accurate, though a bit muted. However, even at a full 90 degrees to the left or right, the colors barely faded.

Lenovo IdeaPad 100S

According to our tests, the screen on the IdeaPad 100S can reproduce 62 percent of the sRGB color gamut, which doesn't allow for the richest shades. However, this showing is a bit better than the Aspire Cloudbook 11 (59 percent) and the 100S Chromebook (58 percent) and a tiny bit worse than the Asus X205TA (68 percent).

Ideapad 100S Display: Test Results
Benchmark Score How it Compares
Brightness 243 nits Better than competitors
Color Gamut (sRGB)   Better than competitors
Color Accuracy (Delta e) 3.3 Above average


The100S's brightness rating of 243 nits is better than the Asus EeeBook X205TA's mark of 217 and about on par with the Acer Aspire Cloudbook 11's rating of 250 nits.

The IdeaPad 100S's bottom-facing speakers provided sound that was loud enough to fill a living room but not exactly high fidelity. When I listened to Styx's guitar and drum-heavy "Blue Collar Man," the percussion was very tinny, but surprisingly, there was a good separation of sound between the left and right sides. Major Lazer's synth-laden "Lean On" was clearer, but still a bit distorted. The audio fidelity and volume on both songs was much better when I placed the laptop on a flat surface rather than balancing it on my lap.

Keyboard and Touchpad

With only 1.2 mm of vertical travel (1.5 to 2 mm is typical) and a flimsy base that flexes like a trampoline as you type, the IdeaPad 100S's keyboard is a mixed bag. However, the scallop-shaped keys are fairly large, easy to target and have a snappy feel, thanks to a solid 60 grams of actuation force. On the 10FastFingers typing test, I scored 92 words per minute with a 2 percent error rate, which is on the low side of my typical 92- to 95-wpm time.

Lenovo IdeaPad 100S

Despite the flaws, the IdeaPad 100S offers a far better typing experience than the Acer Cloudbook One 11, which has keys that are .5 mm narrower, 2 mm shorter and cramped together with .5 mm less pitch. We just wish Lenovo had avoided flex, like it does on the 100S Chromebook, which is $20 less.

In our tests, the 3.3 x 1.75-inch touchpad offered highly accurate navigation around the desktop, but it does not support pinch-to-zoom, two-finger scrolling or other gestures. On the bright side, the pad has two discrete buttons for left and right clicking -- a rare but very useful feature that helps it avoid the jumpiness we see on so many clickpads.

By contrast, the Cloudbook 11 has a buttonless touchpad and supports gestures, but suffers from a lot of lag; pinch zooms occurred a second or more after we performed them. The Asus EeeBook X205TA's pad also supports gestures, but also performed erratically when we used them.

Lenovo IdeaPad 100S


The IdeaPad 100S stayed cool at most touch points. After streaming a video for 15 minutes, the touchpad and keyboard reached a reasonable 90 and 89.5 degrees Fahrenheit, respectively, which is below our 95-degree comfort threshold. However, the bottom reached a full 103.5 degrees after streaming.

Ports and Webcam

The Lenovo IdeaPad 100S crams a number of useful ports onto its small frame. On the left side, you'll find a proprietary power port, HDMI-out, an audio jack and a microSD card reader, which you can use to add to the laptop's meager 32GB of internal storage.

Lenovo IdeaPad 100S

The right side houses two USB 2.0 ports, which are more than good enough for most peripherals you might attach, but we wish at least one of these were USB 3.0 so we could take advantage of the fastest external hard drives.

The 0.3-megapixel webcam took blurry, dark images of my face in every lighting condition I tested. The pictures were a bit more detailed and easier to see under direct light.

Considering that it's powered by a low-cost, 1.33-GHz Intel Atom Z3735F CPU and 2GB of RAM, the Lenovo IdeaPad 100S offers really solid performance that's good enough for Web surfing, editing documents, viewing movies and multitasking. When I had a dozen Chrome browser tabs open, I was able to watch a YouTube trailer of Star Wars: The Force Awakens in one window while editing a Google doc in another, without a hint of lag. Performance was equally smooth when 100S was playing an offline clip in Windows Media Player.

Lenovo  Ideapad 100S (Atom Z3735F  / 2GB / 32GB eMMC): Performance Tests
Benchmark Score How it Compares
Geekbench 3 2,195 Comparable to competitors
Spreadsheet Macro Test 22:05 Comparable to competitors
File Transfer Test 31 MBps Slower than competitors


The IdeaPad 100S scored a solid 2,195 on Geekbench 3, a synthetic benchmark that measures overall performance. That's on par with the Asus EeeBook X205TA (2,212), which has the same CPU as the 100S, but nearly double the Celeron N3050-powered Acer Aspire One Cloudbook 11's mark of 1,285.

Lenovo IdeaPad 100S

The IdeaPad 100S's 32GB of eMMC storage memory took 2 minutes and 24 seconds to complete the Laptop File Transfer test, which involves copying 4.97GB of mixed-media files. That's a rate of 31 MBps, which is a little less than you'd get with most mechanical hard drives, and also slower than the Cloudbook 11 (34.6 MBps) and the X205TA (41.4 MBps).

Forget about crunching large sets of data on this low-cost laptop. The IdeaPad 100S took a glacial 22 minutes and 5 seconds to complete the OpenOffice Spreadsheet test, which matches 20,000 names with their addresses. The X205TA took a similar 21 minutes and 36 seconds, but the Cloudbook 11, which is slower on other benchmarks, finished in just 11 minutes and 54 seconds.

You can watch movies on the IdeaPad 100S, but forget about gaming. Lenovo's low-cost laptop scored 15,081 on 3DMark Ice Storm Unlimited, a synthetic graphics benchmark. That's about the same as the X205TA (15,111), but a bit behind the Cloudbook 11 (18,314).

Battery Life

The IdeaPad 100S lasted a strong 9 hours and 48 minutes on the Laptop Battery Test, which involves continuous Web surfing over Wi-Fi at 100 nits of brightness. That's well ahead of the Acer Cloudbook 11's time of 8 hours and 4 minutes. However, the Asus EeeBook X205TA lasted a full 12:05, while Lenovo's 100 Chromebook endured for 11:19.

Software and Warranty

The IdeaPad 100S comes with a free, one-year subscription to Office 365 Personal, which you can activate simply by opening a preloaded Office install app and signing in to your Microsoft account. The subscription, which would cost around $60 if you bought it on your own, entitles you to install and use the latest (2016) versions of Word, Excel, PowerPoint, Outlook and OneNote for 365 days and includes 1TB of cloud storage.

Office 365 Activation

Perhaps because of its limited storage space, Lenovo puts almost no preloaded software on the IdeaPad 100S. In addition to standard Windows 10 apps, the laptop comes with One Key recovery, an emergency restore program which launches when you hit a small button above the F2 key. There's also a Manage Account app, which lets you sign up for a Lenovo account, and a PDF of the instruction manual and Lenovo Solution Center, which does hardware scans and links to Lenovo's support forum. You can also download helpful Lenovo apps such as Reachit, which helps you manage your cloud storage accounts, and Shareit, which allows you to share files with other PCs.

Lenovo backs the IdeaPad 100S with a standard one-year warranty on parts and labor. See our Tech Support Showdown to find out how the company's phone and Web help resources stack up to the competition.

Bottom Line

The Lenovo IdeaPad 100S offers a ton of value, combining long battery life, an attractive design, solid performance and free Office 365. This laptop would be an even more compelling choice if its keyboard, which generally feels good, did not flex and its touchpad supported gestures. If you want even better endurance in this price range, consider the Asus EeeBook X205TA, which lasted a full 12 hours on a charge, but has a dimmer display and comes with Windows 8 instead of Windows 10. However, if you want the best overall Windows laptop under $200, get the Lenovo IdeaPad 100S.

    the clock seems to run slow no matter what I try to do. Battery bar shows the wrong battery availability and the anniversary update wont as there isnt enough space left on the cdrive. Is it because I run google photos etc on it? Any help would be really appreciated. PS not to technical a response would help!


    Can I get a Red Hat Linux installation on the Lenovo IdeaPad 100s along with Windows10 as dual boot?

  • peter Says:

    Keyboard is terrible. Task bar does not always space, the correct letters do not always show when typing if they show at all. Other times the correct letter as well as the letter nearest to it show. Type t and ty is what you get. This is very annoying. Haven't experienced this with my ASUS T100, which purchased for the same ball park price. Other than that, I have no complaints.

  • bjbell Says:

    I bought this as an open item for $120. Whoever owned it first,took it home, booted it once, and brought it back.
    It's in new condition and a steal at $120.

  • Colin Says:

    I'm thinking of getting this laptop. I'm saving up for it. But I'm gonna order it from best buy and their price for it is like 149.99 so it's a pretty good deal.

  • Daniel Says:

    I clicked the link and this is now a chromebook, apparently. You might want to correct the specs since it doesn't run windows.

  • Debra Bell Says:

    We have changed the TW setup 3x with tech support, then changed out the modem yesterday but same issue. My brother is mentally slow and it gets very frustrating for him. Uses U-tube, etc. Appreciate any suggestions as we don't live together, so it makes it difficult to help. Thanks

  • kangaroo120y Says:

    Got one of these about a month back as a replacement for a (finally) failing 7 year old Acer laptop. I am quite impressed with it. Along with using it to watch movies and my novel writing, I also throw a couple of games on it to test. F.E.A.R. ran very well on medium details and it has no issue with Civ3 (I keep civ5 but civ3 is enjoyable on the go) and Defense Grid.

    This years NaNo and Camp NaNo events will be taken care of :)

  • Rob C Says:

    Correction on my comment to Estevan. The USB ports are on the right. I mistyped in my original comment but then perhaps you did too. No worries either way, just wanted to let you know the USB mouse was possible but, again, perhaps I am misreading or misunderstanding your note.

  • Rob C Says:

    I was reading some of the comments and as I am basically using this as a smaller, lightweight alternative to my bigger laptop when I chose to write away from home, I cannot really dispute the issues with the OS or the sound (I always use earbuds).

    To Estevan, I am using a USB mouse plugged into the left side. Not certain why it not being on the right would preclude you from using it.

    To Donald, They hid the power Tab? You couldn't find it and then you have an issue with using your fingernail. I am not certain how bad your eyes are or how large your fingers are that you need a map to find the button and then can only use your fingernail but perhaps instead of complaining about insignificant issues you accept that it not being used by power gamers or people writing millions of lines of code. And if you are one of these people, use another laptop. This is basically a tablet with a keyboard!

  • khursheed wani Says:

    best mini laptop but unfortunately new os cant be install

  • Donald Says:

    (Second comment) How could I have forgotten this major design flaw: they hid the power tab. It's on the left side of the keyboard near the headphone jack, and you have to use your fingernail to push it in. Whoever designed that should be fired.

  • Donald Says:

    It's a basic laptop. Period. It's pretty slow to start up, the speakers are useless without an earphone or headset and the camera sucks big time. You wouldn't want to use the cam if you can help it. Still, it not bad enough to return, but I wish I had bought something different. Could not recommend it.

  • estevan Says:

    i have one ... and i have to say only problem i have with this computer is the audio .... well there isnt much of any audio its soooo quite you have to put your ear to the laptop to hear anything ... but other then that ... its a great computer.. it surfs the web ...and plays some basic games ... i do wish they would have put USB ports on the right hand side .. so you could use a mouse if you choose to

  • Jessica Says:

    Lenovo 100S - you mentioned that gaming was out of the question would that include games on facebook or similar?
