dmidecode

tool for listing hardware information and decoding it into human readable form. This tool decodes the DMI information.

Examples

Show system serial number

sudo dmidecode -t system | grep Serial
sudo dmidecode -s system-serial-number

Show memory info including max installable

sudo dmidecode -t memory

Show bios version

You may need to grep for a different string, but even then it doesn't always show the info because not all machines support this.

sudo dmidecode -t bios | grep -i revision

Shower power supply information

This doesn't always work. Some power supplies are not supported.

dmidecode -t 39
