The ThinkCentre A Series is Lenovo’s line of business desktops, originally IBM ThinkCentre. After Lenovo bought IBM’s Personal Computing Division in 2005, the A Series continued in towers, small-form-factor desktops, and all-in-one designs (AIOs). The first model was the A50p, a basic business PC with enough storage for documents and apps.

Key models and highlights:
- A53 and A55 (2006): solid mid-range desktops. The A53 used a Pentium D dual-core; the A55 used a Pentium 4. They offered modest RAM and storage and were described as true business machines, with good software bundles but limited expansion.
- A60 (2006): a mid-range desktop praised for useful features and an easy-to-upgrade toolless chassis, though it was slower than Core 2 Duo systems and had shared video memory in some configs.
- A61e (2007): marketed as the smallest, quietest, and most energy-efficient ThinkCentre at the time—compact and power-saving, with limited expansion.
- A58 (2010): announced in March 2010, with dual-core Pentium E5200 and options up to Core 2 Quad; included usable RAM and hard-drive options, integrated graphics, and basic audio. It was noted for build quality and energy efficiency, though some ports were limited.
- A70 and A70z (2010): the A70 was a traditional desktop, while the A70z was an all-in-one. The A70z offered quick setup and a fast 35-second boot, handled HD video and Photoshop well, but its integrated graphics didn’t support 3D gaming. It received positive reviews from several outlets.

Overall, the A Series offered a range of business-oriented desktops to fit different workspaces, balancing reliability, performance, and energy use across various sizes and configurations.
