I have Dell optiplex 780 machine with win 7 32bit OS. [FONT=&quot]I had no issue when it was new machine to put the machine in hybernation, now it does not go into the hybernation mode! it comes back in few secs. Also it does not recognize the external HD ... I cant backup my data files :( never had this problem when the machine was new. I run security software but this was not an issue before. If some one has any suggestion what is causing this issue [/FONT]I will be very grateful
