Zip archive for the Asus S400CA mainboard, revision 2.1, carrying a Disable RAM label. The contents relate to switching off the onboard memory chips, a repair approach used when soldered DRAM is faulty and the laptop should boot with a slot module only. Expect layout or schematic data that a boardview viewer or PDF reader opens for locating strap resistors and test points. Check that the PCB silkscreen matches rev 2.1 and inspect the memory power rails for shorts before modifying anything on the board.
