Acer Travelmate 7560 getting randomly drops into sleep mode is another problem found by it users. It can be a serious problem as one of those users takes his laptop back to the Acer and the technician said there was nothing wrong with his laptop at first. But then they want to charge for a fresh install as they said that they had found a loose wire.
I don’t judge that Acer technician is right or wrong, but first you need to know the sleep and hibernation issues are mostly related to
the BIOS & motherboard. As in this case the laptop that has a trouble is Acer Travelmate 7560, occasionally the sleep switch is triggered by people who have magnets on their wrists (those copper oxygenating the bloodstream bracelets for instance).
So the last solution’s way is try updating the Acer Travelmate 7560 BIOS, it should be fix randomly drops into sleep mode. If the same
problem still appears, you could class it as a mainboard failure. So better send it back to the Acer service center for repair and asking
for a more expert technician to look at it.
