... But the machine cannot run, until the OP obtains a
power source for it. That's why we cannot do any Captain Obvious
procedures in this case. dmidecode is one source of information,
even when the machine has no OS in it (and you are using a LiveCD
instead). But you need power, for any easy-to-do electronic procedures.
CPUZ has a DMI section in the text report save-able in the last tab.
The file is huge. This is just a tiny (edited) section of the file.
dmidecode may have originally been written at Intel, but I'm not
sure about that.
DMI
-------------------------------------------------------------------------
SMBIOS Version 2.8
DMI BIOS
vendor American Megatrends International LLC.
DMI System Information
manufacturer Micro-Star International Co. Ltd.
product MS-7C56
DMI Baseboard
vendor Micro-Star International Co. Ltd.
model MPG B550 GAMING PLUS (MS-7C56)
DMI System Enclosure
manufacturer Micro-Star International Co. Ltd.
chassis type Desktop
Most machines would have a plate on them somewhere, with some
details about the equipment. My Acer has a plate on the top surface,
which is a very useful place to put it. It allows the laptop
to sit on the computer table at my computer store, and customers
can see immediately what the model number is, write it down, and
go home and look up the particulars for it.
But some manufacturers are like PC-Chips, and they strip
all identifiers off the equipment. That's why, worst case,
and only with some luck, you might find a part number on
the battery pack, which can be correlated with the dimensions
of the thing to establish a model without using electronic identification.
You can always unsolder the BIOS chip and dump the DMI section manually.
It's just text after all, so a PROM programmer would make it accessible to you.
(There are portable devices for SPI chips, which is another way to do it.
They have a clip that fits onto the chip.)
On a laptop, the DMI strings would be slightly different in nature, and
be more likely to have a model number for the laptop.
At my computer store, if the tech builds a desktop for you, one of his
build steps, is to reach into the DMI, and record the store name and
particulars in the DMI. If you look in the DMI of my first PC computer,
you will find the name of the (now bankrupt) computer store that did
the build. They do the DMI, around the same time they glue that
tiny square computer store logo, to the computer case.
