How to Tell How Old My Computer/Laptop Is?

There are 3 different methods you can use to check your computer/laptop’s age:

  1. By checking your laptop/computer’s serial number and
    1. using the manufacturer’s website
    2. contacting the manufacturer
  2. With the help of BIOS version via command prompt: systeminfo.exe
  3. By checking the release date of your CPU

1) Find the Serial Number of Your Laptop

If you want to know how old your laptop is, with this method, you first need to get your laptop/computer’s serial number.

While a desktop computer contains the serial number on its back, a laptop (including MacBooks) will have it on the underside of the chassis.

a) Check On the Manufacturer’s Website Using The Serial Number 

You can easily get an answer to your question: “How old is my computer?” by going to the manufacturer’s website. Here, we take an HP laptop as an example. 

  1. In your web browser, search for:

Brand name + laptop warranty lookup

For example: hp laptop warranty lookup

google search

  1. Click on the official HP Support for a warranty check.
  2. Type in your serial number in the space provided. Make sure you input the correct country of purchase.

b) Call the Manufacturer or Check Online With the Serial Number

Once you have found the serial number, contact your laptop’s manufacturer by phone. The customer service representative will provide you with details on when your laptop was manufactured.

Or, you could simply check online: just type in the serial number into Google and you should see the manufacturer’s website, along with the details about your laptop.

2) Run Command Prompt: systeminfo.exe

Although Run Command Prompt tells the original installation date of your Windows, this may not be accurate in some cases as the date keeps changing every time a major update of Windows takes place.

That’s why we would recommend that you check the BIOS version instead. It is not only more accurate but easy, as well. The steps are as follows:

  1.  Press “Win + R” simultaneously. Type “cmd” in the Run app. Then hit “Enter”.
Run Command Prompt: systeminfo.exe
  1.  A new window will appear. Type “systeminfo.exe”, then press “Enter”.
Run Command Prompt: systeminfo.exe
  1. Scroll down and search for the “BIOS Version” in the list. Check the date on the right side.

3) Look Into the Release Date of Your CPU

Although this is not a perfectly accurate method because manufacturers tend to use older generations of processors, it will, nonetheless, give a decent estimate.

Here is how you can check your CPU’s release date:

  1. Type “system information” in your Window’s search bar and hit “Enter”.
Windows system information
  1. Search for the “BIOS Version/Date” from the system summary that shows up.
  2. The date listed in front of the BIOS Version is the same on which your laptop was released.

How to Check the End-of-Life Date of Your Chromebook?

The Chromebook is different from other laptops in that its system has an expiry date.

Although this doesn’t mean that the laptop will stop working altogether when it reaches the expiry date, it will no longer get the updates from Google.

If the laptop is no longer updated, the system faces compatibility errors. That’s why it is extremely important to keep a check on your Chromebook’s End-of-Life date.

You can check your Chromebook’s system expiry date with the help of the following steps:

  1. Open the Settings menu on your Chromebook.
