Lenovo A540 Review: Small Footprint, Big Computer


When the A540 arrived, I was taken aback with how much computing has advanced in my lifetime. In our Lenovo A540 Review, we'll take a look at how this All-In-One performs.

Large display, small footprint.

Wireless mouse may cause some headaches.

If you’re looking for an all-in-one multitouch device that doesn’t take up a lot of space but gives you good screen real estate to work with, the A540 definitely deserves a look. You’ll have lots of room for multitasking and it should handle most of...

Read the Specs


This is a great all-in-one PC with a couple caveats. - The flexibility of the display is amazing! Pretty much any angle you can imagine. Up like a monitor. Hanging over the desk so you can utilize all that the touch interface has to offer. Even almost...

Think Twice Before You Purchase


From the moment I powered up the computer, I have had issues with it. First it was with phantom touchscreen tapping which made it impossible to use the computer. Calling support was the worst experience I've had in years. Was given the option of paid...

All in One Great Buy


I had read all the reviews and looked at this all in one very carefully. Have only had it for two weeks but I love it. The keyboard was junk as described by other customers so look for a keyboard because you will not like this one. I accidently dropped...

I have no reason to question the quality and performance of the computer itself. The problem--and it is not a small one-- lies in the fact that the item was advertised as Win 10 ready, when in fact it was not. After three days of use, I found two...

Lenovo A540 System

Nice machine


So far I do love this computer. It's compact, fast and has a great monitor. I don't recommend the mouse that comes with it, the scrolling doesn't work well. I installed a wired mouse and it works fine. Overall, a very good experience.

Good Computer but could be better


The A540 worked well out of the box. I use it for small business, mostly word processing, billing - no gaming. I was disappointed to learn that it can't easily work with a second monitor - I'll probably have to buy a special connector to see if I can...

Almost Perfect!


Lenovo has a winner with this machine. With the exception of a few things, this device is just about PERFECT! It's visually beautiful, fast, quiet and a joy to use. The touchscreen works great, the tilting feature adjusts to anyone's viewing...

Great looks and value. First AIO and what a joy to get rid of the tower taking up space and spewing heat and dust. With the latest I7, plenty of ram and gorgeous display, this should hold me for quite some time. I hate Windows 8 and installed Classic...
