We have found this to be a particular problem with Dell computers.Įven after telling the Dell PC to “Never” go into power saving mode it continued to do so, often freezing the PC in the middle of a program after the computer had been left unattended for a couple of minutes. The power saving options of the PC or laptop and Windows 7 do not sit happy with each other resulting in the PC going into sleep mode after just a few minutes of being left unattended. Some computers have a conflict with Windows 7. Does your PC go to sleep without warning resulting in data loss?
