FEATURES

SLEEK, STUNNING DESIGNTRUE MULTIMEDIA POWERGET THE TOUCHSAVE TIME, DON'T WORRY
IdeaCentre A Series space-saving desktop PCs are wall-mountable and ideal for multimedia.

Make a statement with our gorgeous, space-saving all-in-ones. They are thin — with
profiles starting at well under an inch — but they deliver 21-23 inches of full HD beauty
in an adjustable, tilting, frameless screen. Optional wall-mount kit and single-cord design
mean you can display them anywhere you want. Like, on a pedestal.

IdeaCentre A Series all-in-one PCs offer home theater sound and video in a thin, beautiful package.

Take entertainment to new heights with a high-contrast LED display and rich sound to rival
any home theater — powered by up to 2nd generation Intel® Core™ i7 processor with Intel
Turbo Boost Technology. Convert to a second TV with optional tuner or responsive gaming
environment with multi-function remote. Robust Dolby® stereo sound will help drown out
the inevitable "oohs" and "aahs."

IdeaCentre A Series multimedia PCs with Bluetooth

You'll appreciate our wireless Bluetooth® mouse on select models, not to mention our acoustic,
multitouch screen. The breakthrough touch technology on it (which is being used in a number
of new medical applications) uses sound waves to detect input more accurately.

An IdeaCentre A Series all-in-one PC saves space and combines multimedia capabilities with computing power.

Get booted up and surfing in no time with our simple single-cord setup. Take regular
backups — and recover lost files easily — with Lenovo Rescue System.

Its slick and shiny exterior merited a second look even from jaded souls like us, while our unscientific polling of nearby laypersons ended with the conclusion that the A300 is 'gorgeous.'
