Welcome to the UN Tech Help Centre

Welcome. This is where we’ve put everything we’d normally talk you through over the phone: what our grades mean, how to set up your new machine, what to do when something goes wrong, and how the warranty works. Have a browse, and if you’d still rather just ask a person, that’s always an option too.

If you’re buying

Start with What “refurbished” actually means: what we do to every machine before it goes on sale.

Then Understanding our grading. This is the one people tell us they wish they’d read first: it explains why a Fair machine performs exactly like a Premium one, and what you’re actually paying for when you pay more.

If the specifications mean nothing to you, you’re far from alone, and Choosing the right computer translates them into plain English and tells you which ones actually matter. (Short version: storage and memory matter; the processor matters less than you’d think.)

If you’ve just bought

Setting up your computer takes you from the box to a working desktop, and Transferring your files gets your things across from the old machine.

If something’s wrong

Good news: most problems turn out to be small ones. Work through the Troubleshooting articles first. They’re written as checklists, ordered from the most likely cause to the least, and most things are solved in the first two steps, often in a few minutes.

And if it turns out to be a genuine hardware fault, you’re covered. Every device we sell has a 12-month warranty, at every grade, and a claim costs you nothing.

Two deadlines are worth putting in your mind early, because they’re easy to miss: if a device is faulty on arrival, or you’ve changed your mind, you have 14 days in each case. If either applies to you, get in touch sooner rather than later and we’ll take it from there.

If you’re getting rid of an old machine

We’ll buy it if it has value, take it for recycling if it doesn’t, and destroy the data on it properly either way.

Please don’t put it in the bin, and please don’t sell it without wiping it first. Deleting your files does not remove them from the drive, which surprises almost everyone.

Can’t find something?

Use the search bar at the top of any page. It searches the full text of every article, so typing in the exact error message you’re looking at usually gets you somewhere.

And if an article is wrong, unclear or missing, we’d genuinely like to hear about it. Telling us makes the next version better for everyone, and we’re always glad to help in the meantime. Get in touch.
