Schematics for the Compal LA-1861 board, revision R0.4, in a 1.15 MB RAR file. R0.4 is a pre-release engineering revision, so some component values may differ from mass-production boards. The name gives no laptop brand or chipset; LA- belongs to Compal's ODM numbering scheme. Use the diagrams to trace power rails, find test points and diagnose shorts or missing voltages. Extract with 7-Zip or WinRAR and compare the board number and revision printed on the PCB before relying on it.
