Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

What is a refurbished device?

A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

Lenovo ThinkCentre M720S SFF — i5-9400 16GB Business Desktop

A compact small form factor desktop powered by a 9th Gen 6-core Intel Core i5-9400, 16GB DDR4 RAM, and a fast 256GB NVMe SSD, running Windows 11 Pro. Tested, graded, and backed by a 12-month Reboot IT warranty — strong everyday performance in a tidy footprint.

Key Benefits

  • 9th Gen i5-9400, 6 cores: smooth, fast multitasking for demanding office workloads.
  • 16GB DDR4 RAM: plenty of headroom for heavy multitasking and many open applications.

  • Windows 11 Pro: business-grade security, BitLocker, and domain support.
  • Dual-monitor ready: two DisplayPort outputs plus VGA for flexible multi-screen work.

Performance in Use

With six 9th-generation cores and a generous 16GB of RAM, the M720S handles serious multitasking — large spreadsheets, many browser tabs, video conferencing, and business software all stay snappy. The extra memory makes it a comfortable fit for power users who keep a lot open at once.

The NVMe SSD delivers near-instant boots and fast application launches, while dual DisplayPort outputs support a two-monitor setup for genuine productivity. Integrated Intel UHD 630 graphics drive crisp 1080p and higher displays, making this an ideal office, reception, classroom, or home-office machine.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!

Fair tech for price

Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.

Works excellently as advertised.

The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
