Lenovo IdeaPad Yoga 11S – 59385438 Ultrabook Convertible with “Haswell”

Lenovo has refreshed the 11.6-inch IdeaPad Yoga 11S convertible 360-degree-hinge ultrabook, replacing the 3rd Generation Intel Core “Ivy Bridge” processors with the 4th Gen “Haswell”. The first offered “Haswell”-based model is the Lenovo IdeaPad Yoga 11S – 59385438, featuring the Intel Core i5-4210Y dual-core 1.4-1.9GHz chip.

This CPU isn’t a speed demon, but it’s one of the most power efficient and coolest-running processors. It consumes only 11.5 Watts of power. For comparison, the previous Yoga 11S version has the 3rd Gen i5 “Y” with still very low 13W TDP, while the common 4th Gen i5 CPUs ultrabook CPUs (with “U” suffix instead of “Y”) consume 15W. The full-voltage 4th Gen i5 has a TDP of 37W.

Reviews and battery tests of the Lenovo IdeaPad Yoga 11S – 59385438 are not available yet, but it should have a longer battery life than the previous version which scores “up to six hours” on a single charge, according to the PC maker. Regarding the raw CPU speed, it is very likely similar to the 3rd Gen Core i5 “Y”. That means sufficient power for daily home, multimedia, and office tasks, as well as decent multitasking capability. However, the integrated graphics got a significant performance boost. The Intel HD 4000 has been replaced by the HD 4200. Of course, it isn’t a gaming-class GPU. It’ll probably have similar (but somewhat lower) speed to the Intel HD 4400. Please note that the Y-series chips score noticeably lower CPU benchmark results than the corresponding U-series parts.

In other aspects, the Yoga 11S remained unchanged. As a lower-end configuration, the 11S – 59385438 has 4GB of RAM memory and a 128GB solid state drive. Besides the 4th Gen Intel i7-Y, the new 11S is also expected to optionally ship with 8GB of RAM and a 256GB solid state drive.

Unfortunately, the screen resolution remained at low 1366×768 pixels, so if you want an advancement in that field you have to go for the 13.3-inch Yoga 2 Pro with a 3200 x 1800 panel. Both screens support 10-point multi-touch input.

Of course, various operating modes – laptop, tablet, tent, and presentation – are still possible, just like on all Yoga models, including the aforementioned Yoga 2 Pro and the business-class ThinkPad Yoga.

Rounding off the specs, let’s note that the 11S – 59385438 ultrabook and its siblings measure 0.7″ in profile and weigh three pounds. These aluminum-cladded laptops with comfortable AccuType keyboards and single-piece trackpads have stereo speakers, 720p webcam, one USB 3.0 and one USB 2.0 port, HDMI output, a media card reader, and a combo audio jack.

The 59385438 has a gray lid and bottom of the chassis and Haswell-based 11.6″ Yogas are also expected to ship in orange color.

Lenovo’s IdeaPad Yoga 11S – 59385438 will start shipping soon, according to Best Buy. The product page lists Windows 8 as operating system, so it will probably arrive before Windows 8.1 launch on October 18th. Users will be able to automatically upgrade to 8.1 then. The notebook is priced at $800. It’s interesting that the older version has the same price tag.

  1. Does this Lenovo 11s, model 59385438 have a cooling fan? I see no vent holes in your photos like the earlier Ivy Bridge model. Wont it over heat without a fan?

  2. I just ordered the haswell version, i hope it is a smart upgrade from my acer timeline x 4830t.
    And i really hope the battery life can get me through the school day . not a fan of the proprietary charger though..
