A good used computer can save you a lot of money compared with buying new, and for most everyday work it’s all the machine you need. But “used” covers everything from a clean, one-year-old business laptop to a worn-out machine that’s been sitting in a closet since 2017. If you’re shopping for a used laptop or desktop in Las Vegas, a few checks before you pay will tell you which kind you’re getting.
Here’s what we look at at Vegas Micro, and what we recommend you check no matter where you buy.
1. Make Sure It Can Run Windows 11
Microsoft ended free support for Windows 10 in October 2025, which means no more regular security updates for most home and business users. A used computer that’s stuck on Windows 10 is a computer you’ll be replacing or working around soon.
Windows 11 has firmer hardware requirements than earlier versions. In general, you’ll want:
- An Intel 8th generation or newer processor, or an AMD Ryzen 2000 series or newer
- TPM 2.0 security chip turned on
- At least 8 GB of memory for comfortable everyday use (Windows 11 will start on less, but it won’t be pleasant)
If a seller can’t tell you the processor generation, look for it in the model name. An Intel Core i5-12xxx, for example, is 12th generation. That’s one of the first things we check on every machine we sell.
2. Insist on a Solid-State Drive
The single biggest factor in how fast a computer feels is the drive. An older spinning hard drive makes even a decent processor feel slow to boot, open programs and search for files. A solid-state drive (SSD) makes the same machine feel quick.
Ask what kind of drive is in the computer and how big it is. For most people, a 256 GB SSD is the minimum, and 512 GB gives you room to grow. If you find a good machine with an old hard drive, an SSD upgrade is usually one of the most worthwhile things you can do for it.
3. Check the Battery on Any Laptop
A laptop battery wears out with use. A used laptop that looks perfect can still only last an hour away from the charger. Ask about battery health, or check it yourself: on Windows, a battery report shows the original capacity compared with what the battery holds today. If it’s well below the original, plan on a replacement or plan on staying near an outlet.
4. Look Closely at the Screen, Keyboard and Ports
Spend a few minutes actually using the computer before you buy it:
- Screen: look for dead pixels, dim spots, lines or a flickering backlight.
- Keyboard and touchpad: type a full sentence and make sure every key responds.
- Ports: plug something into each USB port and the charging port. A loose charging jack on a laptop is a common problem and an expensive surprise.
- Hinges: open and close the lid. It should hold its position without wobbling.
- Wi-Fi and webcam: connect to a network and open the camera app.
5. Find Out Where It Came From
The best used computers usually come off business leases. Companies replace their machines on a schedule, so these computers are often only a few years old, were built for heavy daily use and were cared for by an IT department. Brands like Dell, HP and Lenovo make business lines that hold up well for years.
A computer from an unknown source is a bigger gamble. You don’t know how it was used, whether it was dropped or whether it’s even legally the seller’s to sell.
6. Make Sure the Drive Was Wiped and Windows Is Fresh
A used computer should arrive with a clean, freshly installed copy of Windows and none of the previous owner’s files, accounts or software. That protects the previous owner’s privacy, and it protects you from leftover malware, unlicensed software and settings you’ll never fully clean out. If you turn it on and see someone else’s desktop, walk away or plan on a full reinstall.
7. Get a Warranty
This is the biggest difference between buying from a private seller and buying from a computer store. A computer from an online listing or a garage sale is sold as-is. If the drive fails next month, that’s your problem.
At Vegas Micro, every used computer we sell comes with a 1-year warranty, and new computers come with a 3-year warranty. Our used machines are current models that have been tested, cleaned up and set up with a fresh copy of Windows, so they look and work like new.
Used or New: Which Makes Sense?
A used computer is a smart choice for office work, school, email, web browsing, bookkeeping and most business software. If you need a machine for gaming, video editing or engineering software, or you want it to last as long as possible, a new or custom-built computer may be the better fit. We hand-build new desktops and servers right here in Las Vegas, and we’re happy to help you figure out which way to go.
