> TP 750Ce 4+16 m 340 Hdd 28.8 (Active) with a bad sys board(I think). > I will be replacing the sys board this month. If anyone has any ideas what > error code 221 is. I would appreciate the help. Tried different memory, no > memory, ect. and it will not go beyond the 221 errorcode. The hardware maintenance manual says 2xx codes are memory errors, or if not that then the system board. It also says to try removing all add-on memory, press and hold the F1 key, power up and keep holding it until the Easy-Setup screen appears. Then select Test and run the memory test - if this fails it says to replace the system board. I suppose this could be just bad memory on the system board - seems like a shame to have to swap out the whole thing, but I don't know how repairable the system board itself is... Billy Y..
