Lenovo C540 Touch review: An excellent budget all-in-one that delivers on performance


The Lenovo C540 Touch may not look like much, but under the hood it delivers some decent performance with an abundance of memory that won't leave you scrounging for more.

8GB of memory ; Very good productivity benchmark scores ; Great keyboard

Weak integrated graphics ; Display recessed deep behind bezel

Lenovo's C540 Touch isn't the sexiest all-in-one we've seen, but it is an exceptional value at just $719 (as of 8/30/13)

Lenovo C540


The Lenovo C540 is a solid choice for users looking for a reasonably-priced all-in-one desktop that can tackle daily home productivity tasks without looking like a total eyesore.

Handsomely designed space-saving chassis. 23-inch HD display is the best in its class. Affordably priced.

No USB 3.0 connectivity. Can't run all of our benchmark tests.

Lenovo C540 All-In-One Desktop PC Review


We first got word of the Lenovo C540 all-in-one back back in November of last year, however it wasn't until January when we saw a complete set of details and some pricing. That news came during CES and while that was a few months back, the C540 has...

Bottom line here, the Lenovo C540 all-in-one seems to be well suited for the intended audience. That is to say the average home user that wants something powerful enough for day to day use. Of course, the good looks and relatively slim design only go...

Space-saving design, Nice 1080p screen, 1TB hard drive, Low price

Pentium-class performance, Basic feature set, No touch screen, Chassis is not user-serviceable

In the cutthroat world of budget PCs, it's hard to stand out from the pack. After all, there's only so much an OEM can deliver for around $500. There's a lot to like about the C540, first and foremost the beautiful screen. But if you are shopping on...

Lenovo C540 Review and Ratings


Its small price, big screen and space-saving design make the Lenovo C540 fine as a kitchen or kid's room PC where most of its duties center around the Internet. But when it comes to performance, you get what you pay for.

Space-saving design ; Nice 1080p screen ; 1TB hard drive ; Low price

Pentium-class performance ; Basic feature set ; No touch screen ; Chassis is not user-serviceable

Lenovo delivers a decent software bundle for the price. There's Lenovo PowerDVD 10 (by CyberLink) for music, video, and DVD playback, plus the PowerDVD for IdeaCentre version that wraps the functionality in a slick Windows 8 skin. The CyberLink...

Lenovo C540 Touch: An excellent budget all-in-one that delivers on performance


Lenovo's C540 Touch is one of the two best all-in-ones in this roundup. And while I have no significant complaints about the quality of its multitouch display, the manner in which the glass is recessed behind the bezel is disconcerting when you're...

Don't buy!


It worked great for a year. If you are looking for a disposable computer then this is the one you want. I would have expected it to last me at least a few years.

I had this computer for just over a year. Of course this is a few months past the warranty. Totally stopped working. Diagnostic so far is the mother board. Getting a repair on a product purchased on line is a nightmare.
