I have an AMD Athlon 64bit machine. I used to run XP but now have Vista Home Premium. With neither of the operating systems could I get the machine to sleep or hibernate. It powers down and seems to be working OK then immediately decides to power-up again. I have tried various power settings without success and recently bought an “eco button” which should also put the machine to sleep but I get exactly the same situation, can anyone help please.
