Additional information
Style meets form & function
Powerful yet balanced. Feature-rich yet practical. The eye-catching 24″ IdeaCentre A540 packs a lot into its space-saving design. With high-performance Intel® processing, discrete graphics, and vast storage, it’s ideal for multitasking, entertaining, or gaming. You can also log in with just a smile, wirelessly recharge your phone, and physically close the webcam.
Inspired by nature, designed for the home
Taking its cue from nature, the eye-catching IdeaCentre A540 was inspired by the cypress tree: perfectly balanced and durable. Sacrificing nothing when it comes to performance, this all-in-one PC is an attractive addition to any home.
Ticks all the right boxes
With Intel® Core™ processing and rich discrete graphics as standard, the A540 runs seamlessly smooth—even with heavy workloads. You can also choose a massive 2TB hard disk drive or a lightning-quick solid-state drive (up to 1TB).
Walks the walk, talks the talk
The A540 doesn’t just look good. Built into the base of the stand is Qi-certified wireless charging technology. So, you can recharge your phone just by placing it on top of the base—without the need to plug in any cables.
Great to look at, even better to watch
With up to 93% screen-to-body ratio and thin, narrow bezels, the A540 gives you less visual distractions and more to enjoy than a regular 24″ display. What’s more, you can opt for a model with FHD resolution—and enhance your viewing experience even further.
Sound to take your breath away
With the A540, a truly immersive audio experience awaits. As well as certified JBL by Harman speakers, there’s Dolby premium sound, two 3W tweeters and one 5W woofer. The result? Powerful, crystal clear, rich sound every time.
Protects what matters the most—you
Your time’s important, as is your privacy. That’s why the IR camera and Windows Hello let you log in quickly, easily and securely—with just your smile. And with TrueBlock Privacy Shutter, you can close the webcam when you like.
Extremely well-connected
Unlike other home computers, there’s no shortage of ports on the A540. As well as USB 3.1 and 2.0 ports, it comes with a 3-in-1 card reader and HDMI—all as standard. So you can easily hook up another screen or device to work or game, or both at the same time.
No screwdriver required
The A540 is designed to hit the ground running. Simply unpack it, plug it in, and away you go. You don’t even need to screw the display into base. What’s more, there are no messy wires to deal with and future upgrades are a cinch to install.
