The ThinkPad E Series (formerly ThinkPad Edge) is a notebook computer series introduced in 2010 by Lenovo. It is marketed to small and medium-sized businesses.

Launch and reviews

The Edge series of ThinkPad computers was introduced at the 2010 International CES in Las Vegas and became available for sale in April of the same year.^{[1] [2]}

For the ThinkPad Edge 13, a review on the Engadget web site said that even though, "it may not carry the premium features of [Lenovo Thinkpad] X301..., but for a budget ultraportable... [there is] little to complain about."^[3] Engadget also tested the battery life of the Edge 13 and discovered that "Lenovo's battery life prediction of seven hours is pretty on the mark." The Edge 13's battery lasted 5 hours and 12 minutes.^[3]

Laptop Magazine reviewed the ThinkPad Edge 14 and found it was "the most compelling 14-inch small business notebook on the market today."^[4]

NotebookReview reviewed the ThinkPad Edge 15 and said that its "build quality seems to be a step down from the 13 and 14 inch."^[5] The website also mentioned that the Edge series in general "feels under built...[and] the Edge 15 fares much worse".^[5]

Reviews of the E220s and E420s were more positive, citing better build quality than other models in the Edge line.^[6]

Features

The ThinkPad Edge series uses processors from both AMD and Intel.^[7] AMD processors offered include the Athlon II dual-core, the Turion II Dual-core, Phenom II Triple-core and Ryzen 2nd, 3rd, 4th and 5th Generation mobile Accelerated Processing Units (APUs). Intel processors used include the Core 2 Duo, Core i3, Core i5 and Core i7.

Voice Over IP (VoIP) features including high resolution cameras and an HD LED screen are also included. All four models offer a glossy LED back-lit 16:9 display capable of playing 720p video.^[8] However the Edge 11 and 13 does not include an optical drive. The laptops came in three colors: Midnight Black (Smooth), Midnight Black (Gloss), and Heatwave Red (Gloss).^[8]

Design

Lenovo designed the laptops to "reflect a new progressive and strikingly clean appearance while retaining ThinkPad durability and reliability". For example, along with the new Island-style keyboard, the Edge series had some keyboard design changes: uniform black keys and the removal of the embedded number pad. The Function keys were re-designed so users could use one finger to access functions such as multimedia keys. Some keys which were rarely used like SysRq were removed.

Gen 1 (2010)

Edge 11

The ThinkPad Edge 11 laptop was not released in the United States, with the X100e serving as an 11.6-inch laptop solution in the US. The laptop was 1.1 inches thick and weighed 3.3 lbs. Like other laptops in the series, the Edge 11 was made available in glossy black, matte black and glossy red. Despite the low starting price, the Edge 11 laptop included some of the traditional ThinkPad durability features, including solid metal hinges. The battery life was better than both the IdeaPad U160 and the ThinkPad X100e laptops.^[9]

Edge 11 (DER Special Edition). A special edition laptop was provided for Australian Year 9 students as part of the Digital Education Revolution (DER) program in 2011.^[10]

Edge 13

The ThinkPad Edge 13 laptop was released on January 5, 2010.^[11] It was 1.2 inches thick, weighed 3.5 lbs (1.6 kg), and fit into a backpack.^[12] The Edge 13 laptop was capable of handling Windows 7 Pro with ease, with multiple applications like Firefox, Microsoft Word 2007, GIMP, TweetDeck, and iTunes at the same time.^[13] It did not feature Intel’s Arrandale platform on release, and was launched with an prior generation CULV processor.^[14] The lack of processing speed, however, was compensated by a gain in battery life. The laptop delivered 6 hours and 58 minutes of battery life in MobileMark 2007 tests.^[15]

Edge 14 and 15

The ThinkPad Edge 14 and 15 laptops were both launched on March 22, 2010.^[16] A web review noted build quality above average, yet not the same as professional grade ThinkPad laptops. One difference was smaller screen hinges which were plastic-faced instead of metal.^[17] While the Edge 14 laptop did not have a roll cage, it was still durable, with no flex on the palm rest, keyboard and touchpad.^[18]

The Edge 15 laptop was noted for having the same features as the smaller laptops in the series, with lower build quality.^[19] The right side of the palm rest displayed flex under moderate pressure. The keyboard tray also displayed slight inward flexing at the optical drive area.^[19] Some positive features included a keyboard that was noted as being very easy to type on.^[20] The touchpad was also noticeably easy to use, with fast response time, no discernible lag, even without adjustments.^[21] But also at the Lenovo support forum, lots of keyboard failures were reported. The price was viewed favorably, with user experience and feature set receiving praise.^[22]

Gen 2 (2011)

Edge E220s, E320, E325, E420, E420s

The ThinkPad Edge E220s and E420s were released in Spring 2011, as an updated, "more premium" line of the ThinkPad Edge.^[23] These newer series are significantly thinner, and include more of the traditional ThinkPad line of features such as the integrated 720p web-cam. Also notable is the return to use of metallic hinges versus the less durable plastic seen on earlier Edge models. Both the E220s and E420s can be configured with up to an Intel Core i7 processor, which offers a higher level of performance than other notebooks of this size category. The surfaces have been accented with a chrome finish around the exterior, and the addition of the "infinity glass" screen, which features edge-to-edge glass paneling on the display. Many design aspects of the E220s line have been seen in the recently unveiled ThinkPad X1, including the keyboard and touchpad design.

Edge E520, E525

The ThinkPad Edge E520 was launched at the same time as the E420. It is the first 15.6" ThinkPad to feature a numeric keypad.

12. Web site: Engadget. Though the 1.2-inch thick Edge isn't as thin as some other modern ultraportables, like the inch-thick ASUS UL30A and ThinkPad X200, at 3.5 lbs it feels extremely light in a hand and it slipped nicely into a backpack for a weekend trip..
13. Web site: Engadget. Performance-wise, we've got nothing to complain about, as the Edge compares favorably to other CULV laptops we've reviewed. With a 1.3GHz Intel Core 2 Duo SU7300 CPU, 4GB of RAM, and a 320GB hard drive our $899 version ran Windows 7 Pro without a hiccup and didn't lag when we had Firefox, Microsoft Word 20078, GIMP, TweetDeck and iTunes all open and running..
14. News: PCMag. The Edge 13 is one of the few laptops that are not launching with Intel's latest "Arrandale" platform, which will have processor names like Core i7, Core i5, and Core i3. Instead, it uses a previous generation CULV platform, complete with an Intel Core 2 Duo SU7300 (1.3 GHz), 4GB of RAM, and integrated graphics. . PC Magazine. Cisco. Cheng.
15. News: PCMag. With CULV laptops, battery life is the biggest claim to fame. Although the Edge 13's 63WH (6-cell) scored almost 7 hours (6:58) in MobileMark 2007 tests, it came up well short against the ASUS UL30A-A1 (10:27) and ACER A3810T (8:39). . PC Magazine. Cisco. Cheng.
16. Web site: Laptop-Review. Yesterday Lenovo launched their two newest noteboosk for SMBs (small and medium sized businesses). They are called ThinkPad Edge 14 and 15, and as the names suggests, the displays measure 14 and 15.6 inches, respectively..
17. Web site: Notebook Review. 27 January 2022 . Build quality is above average compared to consumer notebooks, but a step below business-grade ThinkPads. The screen hinges are noticeably smaller than what you might find on a standard ThinkPad; they are plastic-faced, not metal. ThinkPads have been known for strong screen hinges that last throughout the notebook's life without wearing out..
18. Web site: Notebook Review. 27 January 2022 . Unlike more expensive ThinkPad models, the Edge 14 doesn't have an internal rollcage, but Lenovo still managed to keep the notebook pretty strong. The palmrest, touchpad and keyboard have no discernable flex under strong pressure and the frame doesn't flex if you carry it by the corner of the palmrest..
19. Web site: Notebook Review. 27 January 2022 . The Lenovo ThinkPad Edge 15 offers the same features as smaller Edge models, but falls short when it comes to build quality in the larger 15-inch chassis..
20. Web site: Notebook Review. 27 January 2022 . What makes the keyboard unique is that it's the first Chiclet keyboard I have found that's very comfortable and easy to type on..
21. Web site: Notebook Review. 27 January 2022 . Overall, the touchpad was pleasant to use, with a fast response time and no discernable lag. Sensitivity was excellent and no adjustment was needed out of the box..
22. News: PCMag. The Lenovo ThinkPad Edge 15 has several things working in its favor. For one, it's a cheap small business laptop for those who are looking to buy several at a time. Second, the user experience and feature set are among the best in this category. . PC Magazine. Cisco. Cheng.
