Stylish and super-slim, the Lenovo A540 space-saving desktop features a widely adjustable screen angle that rotates from -5 degrees to flat. This all-in-one PC includes 10-point multitouch, up to Full HD visuals, and immersive JBL® stereo sound with Dolby® Home Theater®.
ULTRASLIM 23.8" TOUCHSCREEN ALL-IN-ONE
Widely Adjustable Viewing Angle
The A540's smartly designed display mount allows you to adjust it across a huge range — from -5 degrees to 90 degrees. That means you can watch it in a vertical position like a PC or television, slope it gently for relaxed touchscreen use, or slide it into a full horizontal position to play two-person touch games.
Stylish, Ultraslim Design
The A540 doesn’t just work well — it looks great too. The stylish, super-slim touchscreen tapers to a mere 4mm at its thinnest point, while a full aluminum shell surrounds the A540's frameless display.
Great for Entertainment
The A540's Full HD (1920 x 1080) display with IPS delivers dazzling visuals and nearly 180-degree viewing angles, while JBL®-designed stereo speakers enhanced with Dolby® Home Theater® offer a rich, immersive audio experience.
Easy File Transfer
Near-Field Communication (NFC) technology makes it easy to wirelessly connect across other NFC-enabled devices — then easily share photos, movies, music, and documents directly by WiFi, with no additional software needed.
Lenovo Motion Control
Use the webcam as an input device — effortlessly flip pages, rewind/forward music, change volume, and gesture other simple commands with the flick of the hand.
Simple Backup and Recovery
Lenovo Rescue System makes it easy to back up and restore data and recover system files — before entering Windows.
