Reviews for the Lenovo IdeaPad S405

Couch potato. Lenovo's IdeaPad S405 comes with a Trinity quad-core and a light case and is very quiet. But, how do its dark glare-type display and its 32 Wh battery blend in with mobile ambitions?

The Lenovo IdeaPad S405 is built around the AMD A6-4455M processor, a dual-core chip clocked at 2.1GHz that also features on-chip graphics in the form of the Radeon HD 7500G. Rounding out the core components are 4GB of RAM and a 500GB hard drive.

Some value-priced laptops offer more than simple affordability, with features and components that belie the budget-friendly price. While these systems may cut corners with wobbly construction or a trimmed down feature set, they do so while still delivering adequate performance. The Lenovo IdeaPad S405 is definitely affordable, but it comes with too many shortcomings to recommend—the sluggish performance and limited capability are too much to give up for the price. For a similar price without the compromises, we recommend the Editors' Choice Lenovo G580.

The Lenovo IdeaPad S405 follows in the footsteps of the IdeaPad S400, delivering a great mix of comfort and portability. For $399, you get a solid AMD processor with good graphics performance in a very slim and light design with above-average audio. However, you'll need to sacrifice battery life to get such a capable Windows 8 machine at this price.

The One Touch Recovery button means nasty viruses and general slowdowns over time can be eradicated in a flash, which is another nice feature for anyone looking for convenient computing at a decent price. Battery life unfortunately is not strong – it just about reaches to 4 hours of surfing. But it’s a light and svelte notebook, it’s good looking, and it suffices for everyday tasks at a very reasonably price.

verall, with the Lenovo S400 you're getting roughly the same performance and similar battery life as the Lenovo S405, but with a different badge attached. It's a confusing situation - we say go with your heart. Once you've tackled this tricky dilemma, you're left with a laptop that looks like an Ultrabook but will probably stay at home mostly. That's not to say the Lenovo IdeaPad is a failure in any way - this is a seriously cheap laptop and if you're looking at the budget end of the market, you'd be mad to buy a similarly-specced laptop that looked run-of-the-mill.

The very first thing that stands out about the Lenovo IdeaPad S405 is its low price. This machine was built for the price conscious consumer, and as such it comes with all the downfalls one might expect from a budget machine. The body isn't built sturdily, features are few, and the hardware is not top of the line. At first glance, it looks sleek with its metallic finish. But it is mainly made out of plastic and feels cheap in your hands. The 14 inch display has a resolution of 1366 x 768 and not full HD. The viewing angles are pretty narrow, and with the performance of the outdated parts, 2,1 GHz AMD A6-4455M APU and only 4 GB of RAM, the machine is sluggish to use. The battery lasts for approximately 4 hours of moderate use, which may be alright for some.

It is not all dismal though - the keyboard is decent enough, despite plastic feel. It is comfortable in use for a long time. The sound quality is unexpectedly good, but boosting the volume will reduce the quality quite a bit. Overall, you should not buy this computer if performance or quality is desired. The laptop is ideal for light word processing and has a low price.

AMD Radeon HD 7600G: Processor graphics card that is built into the Trinity A8 ULV series APUs from AMD. Based on the VLIW4 architecture of the Radeon HD 6900 desktop series. Non demanding games should be playable with these graphics cards. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

Lenovo: Lenovo ( "Le" as in the English word legend and "novo" (Latin) for new) was founded in 1984 as a Chinese computer trading company. From 2004, the company has been the largest laptop manufacturer in China and got the fourth largest manufacturer worldwide after the acquisition of IBM's PC division in 2005. In addition to desktops and notebooks, the company also produces monitors, projectors, servers, etc.

In 2011, Medion AG, a European computer hardware manufacturer, owned the majority of the company. In 2014, Lenovo took over Motorola Mobility, which gave them a boost in the smartphone market.

From 2014 to 2016 Lenovo's market share in the global notebook market was 20-21%, ranking second behind HP. However, the distance decreased gradually. In the smartphone market, Lenovo did not belong to the Top 5 global manufacturers in 2016.

69%: This rating is bad. Most notebooks are better rated. This is not a recommendation for purchase.
