- baseboard-serial-number
- baseboard-asset-tag
- chassis-manufacturer
- chassis-type
- chassis-version
- chassis-serial-number
- chassis-asset-tag
- processor-family
- processor-manufacturer
- processor-version
- processor-frequency
Here are some examples:
Linux command to find serial number of Lenovo laptop
$ sudo dmidecode -s system-serial-number
How to list bios version and date
$ sudo dmidecode -s bios-release-date
$ sudo dmidecode -s bios-version
How to list Laptop model name and make
