How to find out age of computer?


We always get asked ‘How to find out the age of a computer?’

Computers are in almost every household in Australia.   No matter how old or young you are, there is a chance that you have used one at some point in time.   The oldest computer that still operates today was built in the 1940s by Konrad Zuse.    His machine was called the Z1 and it ran on binary code, which is the language most computers today still use to function.    Computers keep getting updated with newer software and different capacities, but they generally work the same way, even if they are hundreds of years old.

The method for finding out your computer’s age depends on whether it is a desktop model or laptop computer.  Desktop computers were first produced commercially 1981 by IBM under their personal computer (PC) brand.  The IBM 5150 was the first model, and it had a 4.77 MHz processor, 16 KB of RAM, and used a cassette tape for storage.

Laptop computers were not sold commercially until 1984 by Toshiba. The T1100 laptop weighed in at 10 pounds and cost $2,995. It had a 10 MHz processor, 128 KB of RAM, and a 2.5-inch floppy disk drive.

How to find out the age of a computer?

The easiest way to find the age of your desktop computer is to look on the back or bottom of the machine for a serial number.  This number indicates when your computer was manufactured.   Once you have this number you can go to the website of the manufacturer and find out the age of your machine.

If you do not have a serial number, look in the system registry under computer for basic information about your computer.   The manufacturing date is usually listed in mm/dd/yyyy format at the top of the screen.  This date tells when your computer was manufactured.

Computer components

Computer parts may also come stamped with a manufacturing date.


Some processors will have a date printed on them that indicates when they were manufactured. These numbers are highly standardized and can be cross-referenced to determine when that particular part was made, even if it’s been chipped from an older processor or placed into a newer socket.

Date codes

Date codes are also used to track when electronic components were manufactured. They are three or four letters followed by two or three numbers. The letters indicate the month, and the numbers indicate the year . For example, “ABM” would indicate that the component was made in November of 2002

There are a few ways to find out the age of your computer, each with its own level of certainty. The easiest way is to look at the date your computer was manufactured. This information is usually listed onscreen when you turn on your computer. If you’re not sure where to look or what to look for, most computers will have some basic information about the system and its components on a sticker or label located somewhere on the computer. The date is typically represented as four letters followed by two numbers. The letters indicate the month, and the numbers indicate the year. For example, “ABM” would indicate that the component was made in November of 2002.

Service Tag

Another way to find out your computer’s age is to check the service tag. This is a unique identifier for your computer that is used by technicians when you need support. You can usually find the service tag on a sticker located either on the bottom or side of your computer. The service tag will list the date of manufacture along with other information about your computer.

Get in touch with the support

If all else fails, you can contact the manufacturer or the technician who supplied you the computer and ask them directly.


If you still can’t find out your computer’s age, it might not have one. Many computer manufacturers do not list the date of creation for a particular model. If this is the case, take a guess based on when other computers in your home were purchased and add two years to that time frame. For example, if your laptop was purchased in 2007 and all other laptops in your household were purchased between 2002 and 2005, then this laptop was probably manufactured in 2009 or 2010.

One way is to open up your computer and look for a small stamp on the motherboard that indicates the date of manufacture. Another way is to check the service tag or serial number on your computer- this number can be found on the bottom of most laptops and on the back of desktop towers. Once you have this number, you can use an online service to decode it and find out when your computer was manufactured.


Lastly, you can use a software program to determine your computer’s age. There are many different programs available, but most of them work by analyzing certain files on your computer that change over time. By comparing these files to a database of known changes, the software can give you an estimate of how old your computer is. While this method isn’t 100% accurate, it can be helpful if you’re not sure when your computer was manufactured.

Software like CPU-Z are capable to give you an approximate age.

How to use CPU-Z?

  1. Download CPU-Z from here.
  2. Extract and run the software
  3. Examine the processor name and Google it.
  4. You should get an approximate date of manufacture from Intel or AMDs website.


So now you know a few different ways to find out the age of your computer. If you’re curious about when your machine was made, try using one of these methods- you might be surprised at what you find!
