dmidecode

Install

It is already installed. Otherwise:

sudo apt install dmidecode

Use

sudo dmidecode will produce lots of output. Consider instead using any of these:

sudo dmidecode -t processor for CPU info
sudo dmidecode -t memory for RAM info
sudo dmidecode -t bios for BIOS info
sudo dmidecode -t system for system info, e.g. manufacturer, model, serial number, SKU, uuid
sudo dmidecode -t baseboard displays info on components built into the motherboard. Apparently my laptop has an 1394 controller!
sudo dmidecode -t chassis displays type, e.g. Notebook, serial number, asset tag, etc.

E.g.

> sudo dmidecode -t memory
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.1.0 present.
