Lenovo IdeaCentre AIO 500 series – simply perfect for a small desk
4.7Overall Score
Name: Lenovo IdeaCentre AIO 500 series
Price (RRP): $from 1999
Manufacturer: Lenovo

The Lenovo IdeaCentre AIO 500 series is its premium all-in-one offering available in both 24 and 27-inch sizes. Slim, space-saving and ungradable – perfect for work or home.

I have never been a fan of all-in-ones (AIO) until recently when in down-sizing my life, I realised that space is a most valuable commodity. The Lenovo IdeaCentre AIO 500 series has a tiny footprint – the 24” has 18.5 (D) x 23.5cm (W) plus the monitor that sits on quite an attractive cooper pip arm above – all in a 10.5kg package.

The Lenovo IdeaCentre AIO 500 series is ideal for small desktops, workstations and – well anything really. It looks great as a piece of furniture too with a cool looking copper pipe monitor arm.

What is a Lenovo IdeaCentre AIO 500 series – AIO?

Price: From $1999

AIO refers to the fact that it is an integrated unit – CPU and monitor all-in-one. AIOs are the only real competition to a laptop and external dock/monitor yet offer some expandability and can use far more powerful Intel Core CPUs as they are not constrained by the need to conserve power.

We tested the 24-inch model with – A540-244ICB

  • Intel Core i5-9400T (option i7-9700T) and other options available with Intel UHD graphics 630
  • AMD Radeon 540X 2G GDDR5 GPU (560X/4GB available)
  • 23.8”, 1920 x 1080, 16:9, 250 nits, 10-point touch screen (touch is increasingly important). Option 27” 4K QHD
  • 2 x 8GB DDR4-2666 DIMM (can use 16GB)
  • Up to 2TB x 2.5” HDD or 1TB M.2 2280 PCIe NVMe SSD
  • Wi-Fi AC and BT 5.0
  • 2 x 3W JBL speakers and 5W woofer and Dolby Premium sound
  • Pull-up 720p camera and dual mics
  • And a plethora of expansion ports and Qi wireless charging pad base

To shorten reviews (for our mobile readers), we use FAIL, PASS or EXCEED for test parameters.

Screen – 24” 1920 x 1080 – EXCEED

It is a 250nit screen – perhaps not as bright as some external monitors but excellent under typical home or office lighting. Its almost bezel-less on three sides and a pop-up camera ensures its smooth lines. The 93% STBR is mounted on a curved copper pipe arm and has -25/+5° tilt.

Colour accuracy is 89% sRGB – is fine for home and office use. The IPS screen has even brightness. It is a pleasure to use.

Processor – i5-9400T, 1.8/3.4GHZ – PASS

The T family has a medium power draw of 25-35W meaning Lenovo can use a less active cooling system. It has a PassMark of 9777 putting it on par with an AMD Ryzen 5 3400G. The i7-9700T  2/4.3GHz has a PassMark of 13360 so if you are a power user this is the one to go for.

During regular use, it maintains <40° but during a stress test increases to 60°. Fan noise is negligible.

Graphics – PASS

For regular use, the Intel UHD Graphics 630 chip drives the screen. The Radeon 540X 2GB is a mid-level GPU that can run less demanding games up to DirectX 12.

The Radeon is for external monitor support and supports MOBA type games – although only to casual gamer level.

Storage – EXCEED

It has a [email protected] SATA 6 HDD user-accessible slot as well as an M.2 2280 PCIe NVMe SSD. The review model had a WD 512GB that had a blazingly fast sequential read/write of 3283/2576MBps. It also handled large files and random read/writes very well.

Ports – PASS

  • HDMI 1.4 – can be in or out (switchable) to use this as an external monitor
  • Gigabit Ethernet LAN
  • 2 x USB-A 2.0 5V/1A
  • 3 x USB-A 3.1 Gen 2 (10Gbps) supporting 5V/3A
  • 3.5mm combo audio
  • SD slot

There is plenty of expansion via ports on the back and side of the monitor. What is missing is a USB-port, but there are three USB-A 3.1 Gen 2 ports that allow high-speed data transfer to external storage.
