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.

Reliable 15.6-inch business laptop with Intel Core i5-8250U 8th Gen quad-core processor, 8GB DDR4 RAM, 256GB NVMe SSD, and Windows 11 Pro — backed by a 12-month warranty from Reboot IT.
The ProBook 450 G5 is built for reliable everyday business computing. The i5-8250U quad-core handles Microsoft 365, Outlook, Chrome with multiple tabs, Teams and Zoom video calls, and PDF workflows simultaneously. The 8GB DDR4 RAM keeps standard business applications running smoothly, and the NVMe SSD ensures Windows loads quickly and applications respond without delay — a noticeably faster experience than older SATA-based systems.
The 15.6-inch screen provides generous workspace for spreadsheets, multi-window productivity, and video presentations. Gigabit Ethernet and Wi-Fi 802.11ac ensure reliable connectivity in any environment, while VGA output alongside HDMI makes this laptop compatible with both older conference room projectors and modern 4K displays — valuable in businesses with mixed AV infrastructure. The full-size keyboard with numpad is particularly useful for accountants and data-entry workers who frequently use numeric input.
The built-in 720p webcam with dual microphone array handles video conferencing clearly, and the USB-C 3.2 Gen 2 port provides high-speed data transfer and charging compatibility with modern accessories. At 2.10kg the ProBook 450 G5 is a standard business laptop — comfortable on a desk all day, and manageable in a laptop bag for regular commuting and client visits.

Fantastic service
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!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
exactly as described and works well , just like the staff down there. 10/10
Very happy, thank you
Just having trouble greeting it linked to the internet otherwise it’s okay.
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.
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.
