after many years a old lifebook E8020D-ATI has begun to show in these last month this error.
But hearing the lifebook, as noise the fan works! I have already disassembled the lifebook E8020 and I've noticed nothing particular...
I work for a service partner: I can buy regularly from FTS the spare parts...
I've already changed tha FAN+COOLER unit, but it was not a regular spare-part bought from Fujitsu: the E8020 is too old and no more supported on every its part... I bought it as "tested but used spare part" on EBAY.
I hope it was OK... but I can't try another spare part... and the error still shows on POST... can it come from mainboard???
