OEM is the abbrevation for Original Equipment Manufacturer. The following survey tries to show the relations between the original laptop manufacturers and their derivated brand names. Please note these relations seem to change continously and are difficult to detect. So this survey is only an estimation.
|Brand -> OEM||AlphaTop||Arima||ASUS||Clevo||Compal||First International Computer, Inc. - FIC||Inventec||LG||NATCOMP||Quanta||Samsung||Wistron|
|Apple Computer Inc.||X||X|
|Hewlett-Packard - HP||X||X|
|Lenovo (former IBM)||X||X||X|

Sometimes it's difficult to know what manufacturer has built the machine or parts of it actually. Linux provides different means to gather information about the manufacturer.
Besides the means provided by Linux, often the FCC ID lets you retrieve information about your original laptop or notebook manufacturer.
lspci reveals information, which you may look up in the
PCI Vendor and Device Lists.
To read out the information provided by the Desktop Management Interface - DMI, you
dmidecode(http://www.nongnu.org/dmidecode/) made by Alan Cox and Jean Delvare. Here
is an example for an ACER TravelMate 430. The command
COMPAL as the manufacturer of the Base Board and the Chassis (note: serial numbers are obfuscated):

Another method is to look for models which are constructed in the same way, e.g. which are using the same accessories. For example laptops or notebooks which use a compatible battery model.
