Small 330 KB RAR archive for the Dell Mini 11 netbook, with nothing beyond the model in its name: no board number, revision or ODM. The compact size suggests a single schematic or boardview file. Open it with WinRAR or 7-Zip and identify the contents before use. Such documents are used to trace power rails, find test points and pin down components around a short circuit on a netbook motherboard. Always compare the board identification inside against the markings on the PCB, as Mini models had several board versions.
