I did a good bit of research on laptops before making a purchase, went into stores, read reviews, etc. A few comments.

A number of people note how the screens are flexible, go into a store and try bending screens, all thin laptops are quite flexible. Seems odd to me too, but if everyones doing it, it must work.

I saw a few reviews about wireless problems with the u310, but saw many other good review so I disregarded. Don't disregard. There is a detailed summary at [...].

Seems to be that lenovo figured out the wifi was really bad, but kept selling units and just fixed it on the new ones. I bought my laptop on Sept 20, it was manufactured on May 28, the fix didn't come out until July 23... The date is printed at the bottom of the tag on the outside of the box, so if you buy in a store you can check.

In my case, the speed seemed not great to me, but the range was terrible. I got maybe 50 feet from the router before I lost signal. Even my phone (which I think has pretty bad reception for wifi) was better than that. I decided to go into work and see if I could pick up signal at my desk and couldn't ... back to the store we go. I read lots of reviews of 2-3 weeks for repairs and the problem not fixed, didn't sound like what I wanted to do with a brand new laptop.

Aside from the wifi issues, it was a great unit, solid build, really nice touchpad, good keyboard, screen was fine. I suppose some people might only use a machine at home, but for anyone that travels around, I think the wifi problems makes this machine a no-buy.

Verified Purchase
The first laptop I received was obviously defected. The bezel around the screen was unattached and the wireless card refused to work at all.

The replacement got off to a better start, however things ultimately ended up in a return and a refund. The body of the laptop is okay. Metal bottom and lid but the inside is plastic. The screen brightness is very low even at max settings and the colors are extremely washed out.

The deciding factor in returning the laptop came down to the wireless card. It just doesn't work correctly. I re installed windows, updated the drivers, upgraded to Windows 8 but nothing helped. It had problems connecting and when it did connect my speeds were horrible.

There are much better alternatives out there for your money. It's a shame, Lenovo used to be my go-to brand.

Do yourself a favor and spend a little bit more for an HP or even a DELL (can't believe I just recommended a Dell laptop).

I ordered this laptop for my wife for xmas. It is going back after two days of light use. Take the warning that there are WiFi issues seriously. Amazon must have a bulk hold on the older models that still have this issue. Do yourself a favor and get something else.

Wifi does not work ... period. What else is there to say? Lenovo should reimburse all purchasers of this flawed product.

How I (try to) use it - note-taking for school, net browsing, listening to music, occasionally streaming movies

- It looks very nice, if not particularly original. (Cough, macbook clone, cough)
- It's light and portable.
- Speakers are decent, as laptop speakers go.
- Battery power is usually pretty good, and is excellent when not using wireless internet. (Not sure how wired internet affects it, sorry.)
- Price was good relative to the specs.
- Once it's up and running, it runs well in terms of how fast things load, plus it's never crashed or frozen.

Cons - the one big problem that would make me never buy a Lenovo again:
After just 2-3 months, the machine sometimes can't be powered up. Charges fine, works perfectly when it's on. But let it hibernate or shut it down, and it sometimes won't turn back on for hours of trying. Then, randomly, it'll work again. After the second stressful day of this happening (with a few days of normal operation in between), I changed all my settings so as to just turn off the screen, but leave the system running. Called Lenovo, and will be sending it back after the Fall semester is finished in a couple weeks. Will update on how that goes. UPDATE (1/26/13) - Slow process, but success! Lenovo sent me a box, I sent it back with the computer in it, they replaced the motherboard and sent it back. Shipping was not slow, but the cost was covered. First day using it again, seems to be alright. Hopefully won't have to update this again!

Cons - other little things that always bugged me:
- DISPLAY - It's just off, for lack of a better word. While using it to take notes on PDFs during lectures, for example, my colors appear slightly distorted compared to my classmates' screens.

Without a doubt the worst wifi connectivity of any laptop on the market. Looks beautiful; but without reliable wifi what good is it?

The following is my post at the Lenovo forum.

My experience with U310 (India, build May'12)

The beginning:
My late evening purchase of U310 was eventful. I'd planned to get a MacBook Air 13" (MBA). But certain reservations about MBA, opportunity to save some bucks & the dark impulse to buy resulted in a predicament.

The conflict:
Same night, as I opened the lid of my new laptop, I could smell -- as everybody here knows -- WiFi issues. Within minutes I was on this thread -- on my desktop -- and my 'experience' of purchase was polluted with regret, fear and disappointment. I stayed up almost the entire night, and my hunt continued in the morning -- I took leave from my work. Threads/experiences confirmed my fear. I owned a defective box.

Suddenly, I could notice other issues with the laptop -- flexing of keyboard, the extremely light keys (which leaves one with a feeling of poor material quality), frequent undesired outputs of trackpad. The overall experience was -- simply -- sad.

The resolution:

I took a suggestion on a thread on Lenovo forum quite seriously -- 'return your laptop'. Most impactful was the article by a 'Bastler' (Second from top, Link: [...]. I am extremely grateful for the active members of the thread.

So, on the next evening of purchase, I went to the retailer and -- after 3-4 hours of persuassion -- finally convinced him for an exchange with another laptop. Those from India may understand the struggle.

After enough research I finally set my mind on MacBook Pro 13" -- of course at a premium. I got it within a week.

The experience of my first Mac was, again simply, awesome.
