Review Lenovo IdeaPad S400 Notebook


Virtually an ultrabook. Members of the slim and affordable IdeaPa

Thin, lightweight and handy; 24 month warranty; Always runs quietly; Low consumption; Good application performance

Fast Ethernet only; Contrast-poor, dark screen; Four GB RAM maximum; Low-capacity battery (32Wh) - short battery life

Both mentioned laptops: Acer Aspire V5-531 and Acer Aspire V5-571G. For want of alternatives, we would also count conventional 14 inch laptops, such as the entry-level models Dell Vostro 3460, Fujitsu LifeBook LH531 and Medion Akoya E4212, to the...

It's pretty, but its poor performance and touchpad leave the IdeaPad S400 behind its competitors

Lenovo Ideapad S400 Review


Lenovo Ideapad S400 laptop has 2nd Generation Intel Core i3 processor, 2GB RAM and 1GB of dedicated graphics. It is priced at 27000INR.

Sleek and Lightweight ; Dedicated graphics (1GB) ; Nice speaker sound

Poor battery backup ; Sloppy touchpad response ; No optical drive

The laptop will feel under powered if you work on pro-development and editing software. However it’s pricing gives it a turnaround if it is to be used for normal home use. It will run HD videos smoothly and has good output from speakers. An...

Amazing Value


With laptops like this why buy a tablet?

Size and weight of an ultrabook, i3 with HD 4000 is a total monster, build quality is fantastic

Doesn't levitate and read my mind

Pretty good if on sale


Was for my girlfriend, she's happy so I'm happy.

Compact and portable ; Good value when on sale ; Decent performance for basic tasks like browsing & watching videos

The only con so far would be that the screen wobbles a lot when you use it for touch, pretty much have to have one hand holding the back of it while the other touches the screen. From what I can tell there's no way to tighten it and it's just due to...

Great for what it is.


I did have some problems with the touch screen of the mine when i bought it at first it would just some times not respond then it got to the point where it would never respond. I called lenova support and ended up sending it in and got it back in about...

For the price its hard to find a better unit that has all of the features included in this laptop. Having both a I3 and a touch screen in one inexpensive package was great and then finding it in a light weight 14" laptop was even better for me...

The battery life on it leaves a little to be desired but i still usually get about 2 and half to 3 hours depending on what i'm doing. It is lacking a CD drive as well which in the current digital age we live isn't all that big a deal just thought it...
