How to find out how old your computer is

TL;DR: Check your computer’s processor, system information, serial number, or manufacturing label to figure out roughly how old it is. If one method doesn’t give you a clear answer, try another to narrow down the date.

Your computer’s age can tell you a lot: how much longer it might hold up, whether it can handle newer software, and whether another repair is actually worth the money. Maybe you inherited a laptop from a family member, bought a used PC online, or simply can’t remember when you bought the thing. Either way, knowing roughly when it was made gives you a much better starting point.

There’s no single method that works for every computer. A manufacturing label or serial-number lookup may get you closest to the actual date, while the processor and system information can help you estimate it when that information isn’t available.

As a general rule, laptops often stay useful for around 3 to 5 years, while a well-maintained desktop may last 5 to 8 years or longer. That’s not an expiration date, though; how the computer was used, maintained, and upgraded matters just as much as the year it was made.

Here’s how to figure out where yours falls.

Use the processor for a quick estimate

If you can’t find a manufacturing date on the computer itself, the processor is a good place to start. It won’t tell you the exact age of the PC, but it can quickly put it in the right ballpark.

On Windows

Press Ctrl + Shift + Esc to open Task Manager, click Performance, then CPU. The processor name sits right at the top.

With many older Intel Core processors, the model number gives you a useful generation clue. An Intel Core i5-8250U, for example, is an 8th-generation chip released in 2017. An i5-12500 belongs to Intel’s much newer 12th-generation lineup.

AMD Ryzen chips don’t follow the same clean logic. A Ryzen 5 3500U, for instance, belongs to a family that launched around 2019, but Ryzen model numbers don’t map to release years quite as neatly as Intel’s do. When in doubt, look up the specific model rather than guessing from the number alone.

On a Mac

Click the Apple menu and select About This Mac. Apple tends to be generous with detail here. You might see something like a MacBook Air (13-inch, Early 2015), which answers the question outright. If your Mac runs Apple silicon instead of an Intel chip, the chip generation itself is a clue. The M1, for example, first showed up in Macs toward the end of 2020.

Check your system information

Your computer’s system information can give you a few more clues, including the exact model, processor, and other hardware details. On Windows, you can also check the BIOS date, although it shouldn’t be treated as the computer’s manufacturing date.

On Windows

Press Windows + R, type msinfo32, and hit Enter. Look for the System Manufacturer, System Model, Processor, and BIOS Version/Date.

The BIOS date can help narrow things down, but keep in mind that firmware may have been updated after the PC was built. Use it alongside the processor, model, or serial number rather than relying on it by itself.

On a Mac

The same About This Mac window covers most of what you need. Click More Info or System Report (the label varies by macOS version) to see additional hardware details. Once you have the exact model, you can look up the years that model was sold.

Find the serial number or manufacturing label

If you have a laptop, flip it over. Manufacturers often print an MFG Date or Manufacturing Date right on the bottom label. Desktops usually carry the same kind of label on the back or side of the case.

No date on the sticker? Look for the serial number instead. Write it down along with the brand and model, then head to the manufacturer’s official support site (Dell, HP, Lenovo, ASUS, and Apple all offer this). Depending on the brand, entering the serial number can surface the manufacturing or shipping date, the warranty window, and sometimes the original configuration the machine left the factory with.

Apple doesn’t usually print a manufacturing date on the outside of its machines, so for Macs, the model number and serial number carry most of the weight here.

Your computer and its parts may not be the same age

A five-year-old desktop doesn’t necessarily have five-year-old parts. Someone might buy a PC and replace the original hard drive with an SSD a couple of years later. The computer is still five, but that drive isn’t.

That’s why age alone doesn’t tell you whether a computer is worth fixing. A slow PC with a healthy processor and a failing drive is a very different situation from an older laptop with a worn-out battery, overheating problems, and no support for a current operating system.

If your computer is giving you trouble, check the parts most likely to affect its performance or reliability:

• SSD or HDD: Drive age and health
• RAM: How much is installed and whether it’s enough for what you do
• Battery: Capacity naturally drops over time on laptops
• Fans and cooling: Dust buildup and poor airflow can lead to overheating
• Power supply: An aging power supply can cause problems on desktop PCs

If age isn’t the real problem, start by looking at what’s causing the slowdown. Many common issues can be addressed before you replace the entire machine; here’s how to fix a slow computer and narrow down the cause.

When is a computer too old?

There’s no exact age when a computer becomes too old to use. A laptop that’s 7 years old may start showing its age through shorter battery life, slower performance, or trouble running newer software. A well-maintained desktop can often last longer because individual parts are easier to upgrade or replace. If replacing the computer makes more sense than another upgrade, buying new isn’t your only option. A refurbished computer can be a good alternative if you know what to check before buying.

Instead of looking at age alone, watch for signs that your computer is becoming harder or more expensive to keep:

• It no longer supports current software or security updates. This can become a security issue even if the computer still turns on and works.
• Basic tasks are getting frustrating. Email, web browsing, video calls, and everyday documents shouldn’t feel like a workout for your computer. If the computer still meets your needs but feels slower than it used to, there may be a few ways to speed up an old computer before replacing it.
• Repairs are starting to add up. Replacing a battery or upgrading to an SSD may be worthwhile. Paying for several repairs on an older machine may not be.
• Your needs have changed. A computer that’s perfectly fine for browsing and doing your taxes may not be enough for gaming, video editing, or other demanding tasks.

Even a 10-year-old computer isn’t automatically ready for retirement. If it still handles what you need, runs supported software, and isn’t constantly asking for repairs, there’s no reason to replace it just because of its age. If the age and condition of your PC are pointing toward replacement, compare trusted places to buy refurbished computers before automatically buying new.
