My Hyperdata MediaGo 980 laptop computer refuses to die. I recently upgraded the DRAM from 128 MB to 256 MB using 128 MB SoDIMMs. The specs describe the machine as having slots for 3 DIMMs. I found a compartment underneath with two DIMM slots. I can't find the third. I contacted Hyperdata support but they aren't sure where the third slot is either. They do agree that the machine can be configured with up to 384 MB of DRAM. The maximum individual size DIMM can only be 128 MB.
