*********Re Review Updates March 20, 2018 *********
Well, it goes from bad to worse...
Having spoken to Lenovo Singapore, where I am currently resident for a few months; It was going to $200 to open the case to diagnose the problem. If it was a motherboard they could not quote how much or how long it would be away as the motherboard would have to be ordered in.
I went elsewhere and I had the motherboard replaced within a few days -- for little more than the cost of Lenovo Singapore to check it out.
But it appears that getting it serviced outside of the company has dire consequences.
Windows is no longer activated and will not accept the original key as it tied to the original motherboard. Researching online shows multiple posts where it should simply be a matter of contacting the dealer to advise that it hasn't been upgraded or swapped to a new PC, it has been repair.
So I contact Lenovo Singapore: Did you do the repair in our service shop? No. It is not under warranty and you did not purchase in Singapore we cannot help you with activation. Phone hung up.
Then I Contact Lenovo U.S: You need to go the Singapore Service Centre to get windows re-activated. I explain that Lenovo Singapore said they won't do it because I did not get it repaired from them and did not purchase from them - I purchased in Lenovo US. Chat window closes.
Finally I contact Microsoft... yes it can be done!
Please send photos of sticker and proof of purchase. I PDF the Amazon invoice - LenovoThinkPad X240 13-Inch IPS Technology HD LED Ultrabook (Intel Core i7-4600U, 8GB RAM, 256 GB SSD, Windows 7 Professional 64.
I take photo of the rear. No Windows 7 sticker with key -- just a small Windows 8. So I also take screen shot windows key currently installed on computer. (The original purchase was supposed to come with windows 8 but was able to be downgraded to Windows 7.) After Windows 7 there are no more stickers placed on the bottom of PCs.
Because there is no Windows 7 sticker I'm out of luck. So now it's changed with Microsoft. Sorry, cannot supply you with Windows 7 key. Your sticker says windows 8, and the invoice says windows 7. I explain that it was the downgrade from windows 8 to windows 7 as was available at the time. She says I cannot give you windows 7 because the sticker says windows 8. And cannot give you windows 8 because it's no longer supported.
Talk about a Catch22 -- Yossarian would be proud! And ironically Windows 7 will no longer be supported in 2020.
So 'thanks' to Lenovo for an expensive product that failed inside 4 years.
And 'thanks' Lenovo Singapore for the lack of service and support in attempting to rectify a problem.
'Thanks' Lenovo US for not putting the right stickers on the computer when I got Windows 7 - whichmeans I was abandoned by Microsoft.

Having used windows since 1996,I have always used the genuine product. I'm not a thief, and I don't appreciate being treated like one.

I can now say I will definitely NOT purchase Lenovo again.And the lack of flexibility by Microsoft means my next PC will be an Apple.

Additional 2 stars removed for lack of assistance after repair from Lenovo and Microsoft.

******** Review Updated March 8, 2018*********
Purchase Date: June 7, 2014
Original Review: August 3, 2014

Computer Died: March 1, 2018

This computer lasted 3 years and 9 months. The motherboard stopped working in March 2018, although there were some issues in late December 2017, where the computer would just go to a black screen / power out. Eventually it went one last time and would not restart. I have been advised that it is most likely themotherboard - which is not worth repairing or replacing. You may draw your own conclusions on my thoughts, but it is highly unlikely I would purchase Lenovo again.

Originally 5 stars, but two stars removed for lack of longevity and that the fingerprint reader was useless

******** Original Review Starts August 3, 2014*********
I know there have been mixed reviews on the X240, especially from long time Lenovo ThinkPad owners.
I was looking for a powerful laptop that I can hook up to a monitor, keyboard and mouse while at home, but be small enough to easily travel with and decided on this one.
One of the major issues people seem to have is with the track-pad. I don't use track-pad buttons very often, preferring to double tap the pad. I still prefer a mouse, but the track-pad works ok for me, when I'm not using the mouse.
The two USB ports could be an issue, but I purchased a small Bluetooth mouse for when I am away from home and it leaves both USB ports free for a hard drive or flash drive.
I like the keyboard, which has a much better feel than my Toshiba, but as I'm not an accomplished typist, the TrackPoint doesn't get much use.
8GB of RAM is enough for what I do, (it would be nice to be upgradeable, but that option seems to be disappearing on ultra-books) and the processor, when teamed with the SSD, moves very quickly.
I'm happy with the standard battery. I get excellent battery life (my recent Toshiba was good for 3 hours when new...) I didn't want the bulk of the upgraded battery, although some reviews like the keyboard lift (and huge boost in battery time) it gives. It is nice to have the option of easily adding a battery, that some other manufacturers no longer allow
I wanted Windows 7 (it came with the pro version), and I didn't want a touch screen. I've tried Win8 and I have to say I'm not a huge fan, but I guess I can get used to it sometime in the future. While it makes sense the Microsoft is moving to a touch based interface for phones and tablets, I don't want to touch my monitor or laptop screen as (A). it is hard work lifting my arms all the time, and (B) I want /need my screens to be crystal clear.I have an iPad retina and there is so much loss of clarity because of fingerprints, the retina screen seems almost pointless, unless you keep it crystal clear. (BTW Touch my laptop screen and I'll break your fingers: )
I was very happy with the price, saving close to US$750 if I had purchased at home and also got a longer international warranty.
One issue I did have was with a 3.0 USB hub. I tried a powered USB 3.0 hub from Anker, however there was some issue with the Western Digital Elements Portable Hard Drive losing connection. Now, I'm not sure where the issue lies, but suffice it to say for me, the X240, WD Passport HD and the Anker USB powered hub, didn't play well together. After several weeks of communication with Anker, the issue was not resolved. I have stopped using the 3.0 Hub and reverted to my older Belkin 2.0 hub, and while the hard drive is slower, it doesn't disconnect. I'm more concerned about damage to the drive and data integrity, than speed. And 3.0 is not required for mouse & keyboard.
Over the years, I've owned Gateway (Win95), Compaq (ME), Acer (XP) and Toshiba (Win7) laptops upgrading about every 5 years. I've always kept my older laptop as a Back Up device and networked. Now that XP is unsupported (and the Toshiba was giving me 90 minutes of battery life) it was time to upgrade.
I can honestly say this Lenovo ThinkPad X240, in this configuration, is the best laptop / ultrabook I have owned.

This laptop refused to shut down and we tried everything. It would just hang. We took it to the local computer repair guy ($100) to fix it and he got rid of all the bloat ware and said he found and fixed some problems in the windows 7 installation (it came with windows 7 profession installed but had windows 8 disks in the box).
Same problem. All our smart people looked at this and finally my wife solved it. Turned out it was the virus protection program that came installed on it that was causing the problems. This was by far the most expensive laptop we have ever purchased and we expected better.
