“`
will display the BIOS release date in a `YYYYMMDDHHMMSS` format. This date reflects when the BIOS firmware was created, which is usually near the system’s manufacture date.
On macOS, the Terminal command:
“`
system_profiler SPHardwareDataType
“`
provides detailed hardware information, including the model identifier and the serial number. Apple’s serial number encodes the manufacturing date, which can be decoded using third-party tools or Apple’s support website.
Linux users can inspect system information by checking files under `/sys/devices/virtual/dmi/id/` or using commands like:
“`
sudo dmidecode -t system
“`
This will output details including the system manufacturer, product name, and serial number. The serial number can sometimes be interpreted to estimate the system’s manufacturing date.
Checking Operating System Installation Date
Another effective way to estimate a computer’s age is by examining the operating system installation date. While this does not necessarily reflect the hardware’s manufacturing date, it often indicates how long the device has been in use.
On Windows, you can find the installation date via Command Prompt by running:
“`
systeminfo | find “Original Install Date”
“`
This returns the exact date and time when the OS was installed. Alternatively, checking the creation date of the `C:\Windows` folder can provide a rough estimate.
For macOS, the installation date can be found by checking the system log files or using Terminal commands such as:
“`
ls -l /var/db/.AppleSetupDone
“`
The timestamp of this file generally corresponds to when the system was first set up.
Linux users can check the installation date by querying the filesystem creation date or examining logs. For example, running:
“`
tune2fs -l /dev/sda1 | grep ‘Filesystem created:’
“`
will show when the root filesystem was created, approximating the OS installation date.
