Hi people.\nAccording tot he specs on the ACER 9420 notebook series the 9424\nshould be able to deal with 4GB of Ram. So I installed a matched set\nKingston. And what happens? The bloody thing only sees 3GB! Anybody\nhave an idea OR done the same without any problem ( in which case I\nhave a hardware issue - still under guarantee).\n\nOther question: The mainbord in the 9420 series has a dip-switch on\nit. ANYBODY have any idea what it is for? ( Acer doesn't seem to).
