4 out of 5 eggsAlmost everything you hoped for

Pros: A solid laptop with an above average processor and an average amount of RAM. Touchscreen was extremely responsive. Pretty cheap for an ultrabook.

Cons: It does come with bloatware, which is to be expected from most companies. You can clear this up by "cleanbooting" it. It does also have a wifi configuration, which can be fixed by googling the laptop model and the term "wifi problems" Update it to Windows 8.1 and it should get smoother in terms of running. Lenovo's tech support could be better, but the online community does a great job of handling it.

Other Thoughts: A lot of bad reviews on here are made by people who don't understand laptops or the basis that people buy computers. Most people, especially tech savvy ones won't try to modify laptops hardware wise without first giving it a professional check. The bad reviews spawn from amateurs who didn't know what they're doing.

3 out of 5 eggsRe-Review: OS now on the SSD

Pros: (Now that the OS is on the SSD, and I've had a little more in-depth experience with the laptop as a whole, I believe a whole new review is reasonable. It's up to Newegg to post it. My older review is under the nickname "Incubus".)

- Laptop boots up before the Windows symbol can even finish it's animation.
- Pretty much anything that involves software installed to the SSD boots up without even having to think about it, snap, just like that.
- Light-weight, exceeds in the mobility factor.
- LCD is nice and beautiful, everything looks slick and great.
- With the disc drive (D:) clear of all OS-related junk, all 465GB are free to fill to my heart's content. Yaay :D

Cons: - Trackpad is still kinda weird, it has this thing I don't like where the LMB and RMB are also touch-sensitive to the cursor. Without practice, clicking around will be seriously annoying in the beginning. Before when I said it was overly-sensitive, that was more of a Chrome issue than anything, I don't have that issue with Mozilla.
- I seriously wish I had checked if it had a light-up keyboard before I bought it, this laptop could really use it. And Bluetooth! Oh how I wish it had crossed my mind!
- It's a one-piece, no access to the RAM, HDD, and battery. Big slap-in-the-face for those who have experience opening up laptops and messing around.
- Don't be fooled by the idea that it has a decent battery life.... it doesn't.....
- Graphics integrated into the CPU, gaming even at lowest settings is a pretty lame experience. I've only tried DotA2 so far. Also be sure to never install a game onto the SSD, my friendly advice.
- For some reason, when you wake the laptop up, putting in your password stalls for a few rather long seconds. You get over it, but it's still a con. Definitely bites a chunk out of the OS-on-SSD pro, or maybe it has nothing to do with that, no idea.
- The bloatware is pretty rancid. I tried to get rid of most, but apparently if I get rid of them all, bad things will happen?
Speaking of bloatware, I am afraid to uninstall this "Lenovo Smart Update", even though it takes up the MOST memory of all background programs, and I still can't figure out what in the heck it actually does, even when I google it.
- Audio is utter trash. Audio drivers are worse. The speakers are whatever, but there's only one plug-in for headphones, and the symbol suggests it'll take headphones with built-in microphones, but no dedicated microphone slot. With typical earbuds, audio is average, but don't you DARE try plugging in professional studio headphones! You've been warned.
- It's generally agreed that Windows 7 HP 64bit is max 20gb of space. With a 32gb SSD, I thought I'd have plenty of room for more. But then the updates came and took a bunch of space. I'm left with 2.82gb as I write this (including all other software I installed), so I have to be on watch, cleaning up w/ CCleaner, uninstalling as many useless-looking things as I can. I have to check on the SSD every few hours, because it just changes out of nowhere to a bigger or smaller number, it's ridiculous.

- ATTENTION: There are random places on the planet where Wi-Fi is just plain impossible to get. I'm typing this about 50 yards away from a room in the building where the Wi-Fi refuses to connect. Insult to injury, I had a Mac laptop sitting right next to it that connected just fine. Where I am sitting now, it works. Apparently this is an issue with the Wi-Fi card that they worked out last year, started building new models with working Wi-Fi cards, but continued to sell the old models to customers. Apparently I am one of the unfortunates who ended up with one of the old model.

Other Thoughts: As I mentioned before, I tried to install Windows 7 on the SSD myself. Hint: Don't do it. If you want the OS on the SSD, you have to try to convince Lenovo to do it for you. I managed to, after the hard drive and OS basically bricked and they accepted to do it through warranty, making a faulty hard-drive replacement claim when I explained to them that attempting to re-install the OS through alternatives methods showed no sign of any of my drives, ever, at all. I sent it in, they sent it back.

When I got it, the disc drive got bigger (from 420gb to 450gb), but THEY DIDN'T INSTALL THE OS ON THE SSD! Also the folder for the drivers was nowhere to be found, when it was originally what came on the SSD. It was just empty this time, so I assumed I had no drivers. I decided to give up on the OS-SSD thing and I installed the drivers online. Every single one gave me an error message. I called Lenovo, they sent me a set of discs that would re-install everything, OS, drivers, etc. The installation stopped at the second disc, and never continued. Result? No more OS, everything wiped completely.

This time I called and raged at them, threatening to find a way to get all of my money back if they didn't fix everything this time, complete with drivers, OS on the SSD, everything to my satisfaction. The first call I made, the entire Lenovo department was "down", and the woman I talked to couldn't help me to save her own life. But eventually I ended up on the phone with someone who helped me fix everything, including this little problem where the warranty claimed to end in August, even though I bought it in December, and that error wasn't fixed for MONTHS! I sent it in, they sent it back. And the OS was on the SSD. Glory to the hypno-toad. AND my disc drive went from 450gb to 465gb. Awesome :P Turns out the drivers are all installed in the Program Files folders of the C drive..... Oh well, at least my OS is finally on the SSD.

BUT NOW I'm having this Wi-Fi card issue, and I learned online that they acknowledged this issue last year, and were fixing it. I seriously wish I had read this looooong before all of this, and apparently I would be solely to blame for not bringing this up during all these back and forth shipments, but I didn't know, so... blah. NOW I HAVE TO SEND IT IN AGAIN SO THEY CAN FIX THE WI-FI CARD, AND WHO KNOWS WHAT THE HELL ELSE THEY'LL END UP DOING TO IT!!!
(I tried to ask if they could give me a Wi-Fi card that goes to 1000Mbps to make up for all I've been through. Apparently it doesn't work like that. Lame.)

Bottom line, it's an okay laptop. It's just.... a laptop. I can hardly even call it an Ultrabook. I bought this when it was $750. Then it dropped down to $500 afterwards. Lovely. It's not too hard to figure out why, either. I strongly recommend you not buy it, at all. I don't know much about the U410, but apparently it has the same issues, plus dedicated graphics. Also dropped to $500? Yeah..... keep shopping.

3 out of 5 eggsNice design, Bad Wifi

Pros: It's thin and light. The interior looks like a MacBook.

Cons: The WiFi barely works. There is no CD/DVD which isn't a huge deal except most WiFi adapters require you to install it with a CD.

Other Thoughts: Not a fan of the slow processor, but for the price, you can't really expect much.

4 out of 5 eggsGood Ultrabook for the Price

Pros: - Thin, sleek form factor, looks a lot like a Macbook Pro with the chiclet style keyboard and brushed aluminum look
- WiFi not an issue so far
- Fast for casual activities (Web browsing, email, word processing, etc.) thanks to SSD
- Light in weight
- Newegg delivery was quick and hassle-free

Cons: - 1366x768 display resolution is a bit low
- Battery life is a little shorter than expected (5 hours with constant web browsing, was expecting closer to 6)
- OS comes preloaded on HDD and not SSD
- SSD capacity is 25GB so after installing Windows 8 x64 and MS Office 2013 there's only 9GB of free space
- Noisy, thanks to the HDD
- Documentation from Lenovo is sparse - no recovery CD or CD containing drivers is included (drivers are available online)

Other Thoughts: I bought this for my mother to use for surfing the web and using Microsoft Office. Works wonderful for this type of usage, though most likely disadvantageous for gaming.

It is an ultrabook, which means there's no CD-RW/DVD-R/W Drive . If you need to clean install an OS like Windows 8, it is recommended to put the installation files on a bootable USB drive.

One other note: by default, the storage drives are configured in a RAID setup. When I was trying to install Windows 8, the installer was not able to detect the drives as a result. I had to go to the BIOS and change the storage setup from RAID to AHCI. This will cause bluescreens when trying to load the preloaded installation of Windows but will allow the Windows 8 installer to detect the drives and format accordingly. I personally deleted all existing partitions and installed to the SSD.

4 out of 5 eggsGood Cheap Ultrabook

Pros: The machine is designed as a low end ultrabook and with a little bit of effort, it can be a very fast machine. I increased the RAM to 8GB and upgraded to Windows 8PRO to boot up from the SSD. It is worth taking the time to format all the drives and reinstall the OS on the SSD and leave the hard drive for files.

I have had some minor issues with quality but at this prices, it is superbly fast, quiet and very easy to work with almost anywhere. Granted it does have a wireless signal issue but I see it as a minor incovenience.

Cons: The hinges fitting on my machine is a little bit off and the lid catches on the left side when I open it. At this point, it is not worth hassling with since the machine is finally configured the way I want it.

Other Thoughts: I am a road warrior with chronic fatigue issues and needed a fairly high speed laptop with adequate storage and also weigh as little as possible. This has been a life saver for me in an excellent combination of weight, cost and performance options.

4 out of 5 eggsexcellent xmas present for girlfriend

Pros: very lightweight, thin, fast enough to play Torchlight II

Cons: - doesn't come with Bluetooth, bought a tiny USB adapter to connect her Jambox
- thin bottom panel buckles ever so slightly making a light "click" noise when you press it, doesn't affect operation

Other Thoughts: My girlfriend is extremely happy with this laptop and so far it can play any games she has tried, the most intensive one being Torchlight II.

It comes with some, but not much, bloatware and was easy to clean up.

Bluetooth was the only big hiccup so far but was easy to fix with a USB adapter I got on newegg.

2 out of 5 eggswireless is junk

Pros: It's a nice looking laptop. Nice finish on the exterior lid.

Cons: As others have stated. Wireless is junk don't think there is any solutions, I'm using a USB wifi adapter in it's place.

The keyboard has flex when typing. The trackpad is alright but clicking feels cheap. The keyboard/trackpad area doesn't match the nice finish of the lid.

Glossy Display if that is a concern.

Other Thoughts: For $450(how much i paid) it's good value if you can look pass the wireless issue.

2 eggs for the wireless fail.

3 out of 5 eggsThere's A Reason it's on Sale...

Pros: - Looks nice. Basic but sleek metallic design, resembles a macbook actually (especially black keyboard keys on silver inside)
- 2x USB 3.0 ports with good transfer speeds (SuperTalent 32GB gets ~109MBps on multi-gigabyte file copies)
- i3-based laptop under $500 (as of this review)

Cons: - Wifi is useless. See other thoughts.
- Trackpad is mediocre, as stated in other reviews. Make the buttons a separate piece of plastic from the actual touchpad and it wouldn't be so bad... silly Lenovo. And no, this isn't like a Macbook where the whole pad pushes in; you're literally bending the edge of the plastic pad to click the left and right mouse buttons.

Other Thoughts: There is a 68-page thread on Lenovo's official forum regarding the Wifi issue. They refuse to publicly release their fix, which is hardware-based; they insist on having customers send it in. Even then, many customers who sent it in for service report no improvement in wifi when they get their unit back. I believe the problem is the antenna design, possibly related to the metal case... it can't be the Wifi card itself, since Intel, Broadcom AND Atheros cards were used and all exhibit poor range and speed issues.

My old Lenovo Y550P gets great speed with my Asus RT-AC66U router... however the best this U310 has done is to connect at a link rate of 48Mbps. Bottlenecks my Comcast blast 50Mbps download speeds to 13Mbps... if I'm right next to the router. 8Mbps in the next room.

Note the lowercase "b" i'm using... mega-BITS per second. Not mega-bytes. 13Mbps = 1.63MBps.

If you're buying an ultrabook, you likely want to have something you can carry with you and hop on wifi hotspots, etc. Therefore, bad wifi is kind of a dealbreaker :( Even at the sub-$500 price I got this for, I'm going to return it. Disappointing, because aside from Wifi this is a nice little machine. If you're willing to plug a $20 3rd-party dongle in one of the USB ports and do it that way, then go for it. Thi

1 out of 5 eggsI cannot discourage you enough

Pros: Lower half of the laptop looks great. Touchpad is responsive enough, albeit clunky feeling. Runs WoW and Diablo 3 at low settings very smoothly even at the same time! I don't use it primarily for gaming, but it's nice to have the option if I'm on the go or in bed.

Cons: I got mine on Black Friday 201. I don't have trouble connecting to the wifi at home, but the range is very short-- I can't use it in the kitchen in my house, though there are other computers there on the same wifi. Whenever I take it anywhere, setting up a new wireless connection is a royal pain in the buns. Easily an hour of clicking this and that, rebooting the computer, rebooting the router, messing with misc settings and suddenly it works for no reason.

Viewing angle is just awful. I lean it back as far as it will and look up at the bottom of the screen, I find that to make it look tolerable. I regret buying it.

Not to mention the bezel around the monitor looks like a car ran it over. I resist the urge to take sandpaper to it or remove it completely. What a joke! Cheapest plastic bezel I have ever seen on any laptop, monitor, or TV. It's easily uglier than even the crappiest bezel you've ever seen on any budget brand TV at target or walmart, past or present. Frankly, it's embarrassing to have someone else even look at my computer, which is a shame because the lower half looks pretty great.

Other Thoughts: Like I said in the title, I cannot discourage someone enough to avoid this. I wanted so badly to like it, and I waited too long and missed my return window. Didn't buy it from Newegg, bought it from Lenovo directly.

5 out of 5 eggs4.5/5; Rounding Up.

Pros: I give it a 4.5/5, and am Rounding up.
-Low Price Ultrabook
-Good Price for Specs compared to Competing Names.
-My favorite looking ultrabook, with the exception of maybe Zenbook Prime's.
-Win 7 (if you prefer 7 to 8, as I do)

Cons: -Does Come With Bloatware
-Not Easily Upgradable.
-Boots to HDD, not that big of a deal.
-Horrible Trackpad, but after a month of using it, it is manageable.

Other Thoughts: Don't listen to the other reviews, not trying to be rude by the people reviewing them are acting like 5 year olds. This is a $450 (at time of writing) Ultrabook, you can't knock it down to one star for bloatware you knew would be there (and is removable). The only reason I put it down to 4 stars is because the fact that its not easily upgradable and the Trackpad is worse than my old laptop for years ago.

I am very pleased with this Ultrabook, and I'm no "noob" to technology, I would have easily given it 5/5 if the trackpad was a little bit better.
