The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by running Furmark and Cinebench together. Room ambient temperatures were 23c.
We measured results with CPUID Hardware Monitor software. The CPU was loaded with Cinebench in a loop and Furmark stress test.
The X220 with Core i7 2620M can get quite toasty inside. The CPU regularly runs at over 80c, peaking at 90c under synthetic stress conditions. Not an ideal peak setting long term. It never crashed however which is reassuring.
We attached 5 diodes to the rear of the machine and measured temperatures after loading the machine for 90 minutes.
The rear of the machine gets rather hot and uncomfortable after loading it for so long. We had a problem keeping the X220 on our lap until it had cooled down for 10 minutes. When we reviewed the ThinkPad X1 last year, we noticed that the optional battery slice also acted as a heat ‘block' underneath so it may be advisable to think about this option when considering a purchase.
good looking machine, very businesslike. shame about the lack of backlight keyboard. thats a bad move.
I have a X220 and it has been nothing but trouble. the battery lost a charge in a month and I had to return it. then they released a firmware update which hosed my bios and I had to return the laptop after that.
Its all working now, but im wondering what will happen next………… very bad experience for me. (it is a nice laptop however as reviewer said, but ive concerns about quality control).
I use it with Ubuntu 11.10 and it works like a charm, everything is smooth and worked out of the box. Also, seller was fast and delivered really quickly. I read a lot of complaints about they not replying emails, but my experience was the opposite, they replied me fast and were accurate. I recommend them too!

It’s all very well saying this laptop looks like the ultimate mobile business warrior’s tool. Sure it has the specs, and the dependable looks. I followed the advice of reviews like this one and shelled out $1,200 for a high-spec X220 but when the laptop’s casing developed a crack on the side by no accident or fault of mine, I was in for a ride from Lenovo Customer Service. The following thread on the Lenovo forum gives you a pretty good idea of what I’ve been through:

My opinion after owning an X220 for five months: not only is this laptop of low quality build, but you can forget customer service. My experience of customer service at Apple on similar issues was lightyears ahead of this. Also: “milspec tested”? Give me a break! And what does “milspec tested” mean without actually getting some kind of milspec certification anyway? You can “milspec test” a fisher price toy and it would come out better than the X220, I’d wager.
Hi wimute, im really sorry to hear that. It is a problem with most reviews to be honest. we only get a week or two tops with a product like this before it has to go back. Ill have a look at that thread. thanks for sharing.
@ Wimute, I’ve been using a Lenovo X220 as my main everyday machine for about eight months and had no problems at all. I can’t comment on Lenovo customer service as I’ve not had any issues with the laptop but in my opinion, the build quality is fantastic.
I want to buy it
Nice review. I’m looking to buy thinkpad this Summer
I’ve owned one for about six months, and I love it. I came from Macs, and so far, my x220 has been more reliable and just plain better.
I am looking to purchase the highest end quality laptop summer/fall 2012
Well I’m now experiencing another design flaw in my X220: I’m starting to see ghosting in the display. Seems I’m not alone: if you bought yours with the option of an IPS display, you’re likely to have ghosting crop up. The thread about this issue over at Lenovo has 47 pages of posts and counting. I’m so shell shocked by the Lenovo customer service experience regarding the crack though that I’m not sure I’ll even bother sending this machine in. They’ll probably tell me it’s my fault again and waste a month of my time with a maze of incompetence and denial.
Have you a link? What are you planning on doing?
