I've not opened the case yet, but am now thinking that the configuration may be stock since: standard menu looks normal for T200, RAM availablre at startup is per stock specification, no optional ROM is installed. I am stumped as to what is happening when MSPLAN is selected. The machine looks and can only be recovered with a cold reset. Is there any chance an issue with backup battery could cause this problem? Is it necessary to create an empty .DO file (or some other format) before MSPLAN will start?
