However, this maximum noise range is common amongst mainstream notebooks and is rarely ever reached during typical day-to-day use. The core will occasionally jump to 900 MHz for very brief moments before falling back down to its base range. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. View online or download Lenovo IdeaPad Flex 2-15 Hardware Maintenance Manual, Regulatory Notice The flexible hinges and IPS screen do allow for wider viewing angles compared to most other notebooks and are advantageous for reducing glare. When combined with the 300 degree hinge, this gives the Flex 2 15 a leg up against competing models that have standard TN panels and regular hinges. The standard one-year warranty applies to all new purchases directly from Lenovo's online store. Our equipped Seagate ST500LM000 500 GB SSHD returns an average transfer rate of 84 MB/sec according to HD Tune, which is only slightly higher than standard 5400 RPM drives and still slower than many 7200 RPM drives. Most importantly, the GPU does not throttle significantly during high graphical loads, but at the same time it very rarely benefits from its maximum 1000 MHz core clock Turbo Boost. All the following disassembly steps should be similar for Flex 2 14 model too. At its core, the Flex 2 15 is a no frills solution for the home or student user in need of a basic notebook for browsing, email, and other light activities. However, such a configuration will run users $999 compared to the 768p $549 base model, so it's a hard recommendation as users can certainly do better than the Flex 2 15 with prices nearing four digits. Under extreme loads for over an hour, the hottest quadrant was measured nearest the ventilation grilles and atop the CPU. The Flex 2 15 (starting at $530, $600 as reviewed) sports a Core i5 processor and a crisp, 1080p display. The synthetic benchmarks 3DMark 11 and 3DMark 2013 place the HD 4400 in our Lenovo close to other notebooks with the same GPU in our database. The display bezel has changed slightly with a more defined edge-to-edge glass cover and a glossier surface to go along with it. The manufacturer offers a wide range of configurations with ULV Haswell generation CPUs starting from a Core i3-4030U up to a Core i7-4510U. While the base model has some draws, we suggest looking into the much better Lenovo Yoga series once configurations go beyond $700. Our model at hand uses the more mid-range Core i5-4210U, which had only recently launched as of 2014. 49.4 °C = 121 F | Room Temperature 27 °C = 81 F | Fluke 62 Mini IR Thermometer, Room Temperature 27 °C = 81 F | Fluke 62 Mini IR Thermometer, 15.60 inch 16:9, 1920 x 1080 pixel, Capacitive, IPS, Monitor ID: LG Philips LGD044F, Monitor Name: LP156WF4-SPL1, glossy: yes, Seagate ST500LM000 Solid State Hybrid Drive, 500 GB, Intel Lynx Point PCH - High Definition Audio Controller, 2 USB 2.0, 1 USB 3.0 / 3.1 Gen1, 1 HDMI, 1 Kensington Lock, Audio Connections: 3.5 mm combo audio, Card Reader: 2-in-1 card-reader (SD / MMC), Realtek RTL8168/8111 Gigabit-LAN (10/100/1000/2500/5000MBit/s), Broadcom BCM43142 (b/g/n = Wi-Fi 4), Bluetooth 4.0, height x width x depth (in mm): 22.1 x 382 x 265.9 ( = 0.87 x 15.04 x 10.47 in), Speakers: Stereo speakers with Dolby® Advanced Audio™, Keyboard: AccuType Chiclet, Keyboard Light: yes, Lenovo Companion, Lenovo SUpport, McAfee Trial, Lenovo Cloud Storage, Microsoft Office 2013 Trial, 12 Months Warranty, 2.608 kg ( = 91.99 oz / 5.75 pounds), Power Supply: 275 g ( = 9.7 oz / 0.61 pounds). The 1.7 GHz dual-core CPU supports Turbo Boost up to 2.4 GHz for two active cores and will run at 800 MHz if on the Power Saver profile. The 15.6-inch ATIV Book 2 and Pavilion 15-n005sg notebooks, for example, have similar runtimes under the same testing conditions and similar battery capacities. Further color analyses with an X-Rite spectrophotometer reveal very inaccurate colors on all tested saturation levels. The final PCMark 7 score of 3725 points is good for a budget notebook and is similar to some older Ultrabooks including the Zenbook Prime UX31A. A 3DMark 11 test on batteries returns a Physics and GPU score of 3120 and 746 points, respectively, compared to 3256 and 798 points on a cold run. Available interfaces are again similar to the previous Flex 15 with some minor rearrangements. Compared to the similarly equipped Inspiron 15 and Aspire V5, the Lenovo scores higher than the former (3022 points) and is slightly lower than the latter (3935 points) as the Acer is equipped with more capable dedicated graphics. The 1080p IPS configuration could be less expensive. Should it be inevitable, we recommend the maximum brightness setting and working away from direct sunlight. Subjectively, system performance feels average and sometimes even slow. Though the display received a slight redesign, its maximum brightness and contrast have not improved compared to the original Flex 15. Unfortunately, blue, magenta, and grayscale see little improvements. However, we stress that such inaccuracies have little significance to the target audience of the Flex series. This is compared to hundreds of megabytes with nearly negligible access times from dedicated SSDs that are becoming increasingly common on Ultrabooks. It is still relatively large (10.5 x 7 cm) with a smooth and responsive glide. Otherwise, most everything else is in line with what we expect from a budget notebook including its run-of-the-mill display backlight and battery life. However, they are quite close to the user on both the left and right-hand edges and can potentially take up valuable desk space. We have already published on past Flex models including the original Flex 15, Flex 15D, Flex 14, Flex 14D, Flex 2 14, and the recently released Flex 10. Note that all current models come with 1366 x 768 resolution displays except for the highest configuration. You can switch the device from laptop to stand mode in seconds, thanks to the Flex … While budget notebooks tend to have high capacities, they also tend to be slow in response and access times. PCMark 8 Home v2 and Work v2, for example, are several hundred points higher on both the Dell and Acer models. 1080p 10-point touch screen can fold back up to 300 degrees. However, more power-hungry users may find the CPU lacking for moderate graphics or editing work. With both Prime95 and FurMark active simultaneously, both the CPU and GPU will drop in performance. Idling surface temperatures are more or less flat across the keyboard and palmrests. For everyday browsing, multi-tasking and light gaming, the i5-4210U should prove sufficient. Sound quality and placement of speakers remain unchanged from the previous generation. They also feel mushy and thus inaccurate, especially the small Enter key. Fortunately, this is not enough to be bothersome at home or at the classroom. Similar devices from a different Manufacturer, Devices from a different Manufacturer and/or with a different CPU, Devices with the same GPU and/or Screen Size. Sounds feel muffled even at high volume and bass, of course, is lacking. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news. When clicking on the touchpad, both the feedback and travel feel unsatisfactory. With just Prime95 active, the i5-4210U CPU will run at a stable 2.2 to 2.4 GHz Turbo Boost and top out at 70 degrees C. With just FurMark active, the integrated GPU will run at a stable 650 to 750 MHz core clock and an 800 MHz memory. The Power button has been made smaller and the Volume rocker is now gone in favor of an optical drive.
