What is the serial number of my RM computer or server and where can I find it
Published Date : 22 Mar 2002   Last Updated : 04 Jun 2013   Content Ref: TEC9819  


RM computers and servers have a unique serial number

Any computer or server manufactured by RM will have a unique RM serial number. It is very important that when you call us that we are given the correct serial number for the particular system involved. It is also important that you use the correct serial number when looking for Knowledge Library articles relevant to your system (remember the first two digits are always letters i.e. WO rather than W0 (zero).

For RM computers and servers:
The main number that we need to know is the serial number.

The serial number is always two letters followed by eight digits - each serial number is unique.

For example:


Please note: MO, TO and WO above are letters. 

What do these letters stand for?

  • WO = Work Order
  • TO = Transitive Order
  • MO = Manufacturing Order

The last two digits denote the batch number (01-99) of a particular configuration. Thus, if you ordered 56 computers of the same configuration, WO52199901 is the first system and would be identical to WO52199956 which would be the 56th system. Systems that are identical in the first 8 characters (two letters + 6 digits) will have identical components and software.

Where can I find the serial number?
The serial number and model number can be found on one or more labels on your system:

  • The back of the computer (or underside of a notebook).
  • If your computer was purchased after July 1998, it may also have a silver label on either the left or right-hand side of the case.
  • Inside the battery compartment of your notebook.

  • It may also be displayed on the General page in System Properties (Start menu, Control Panel, System) of your Microsoft® Windows® system.

In addition it is recorded:

  • In the file C:\RMEQUIP.LOG file (Equipment Log) on your factory installed hard disk (a copy is also often made as C:\RMEQUIP.TXT).
    Note: Systems manufactured after 2007 may contain this list in html format at C:\RM\RMEQUIP\RMEQUIP.HTM.
  • In the Equipment Log (available online from www.rm.com/support from the 'Serial number search' function in the Knowledge Library search page or the My Computer tab).

The RM Equipment Log also contains information about your hardware, the drivers required (shown in red in examples below) and the serial numbers of the components in your system. The serial numbers will help you to identify your stolen equipment, if later recovered by the police.

If you have no serial number label - use RMSysInfo

Please download and run RMSysInfo from TEC999413 in the Other Useful Articles section below. In most cases, this will find the system serial number from the information programmed into the mainboard at the RM factory. It can also identify the type of mainboard you have currently fitted if it has been changed.

This Windows compatible HTML application will list the hardware and software on your system and can be very helpful in identifying the type of mainboard you have, what drivers you need and how much memory is currently fitted (and free memory slots), MAC addresses, GUIDs, hardware serial numbers, etc.

You can also email the results directly to anyone at RM provided the computer has Internet access (no school mail server or user email account needed).
