When you put your computer into an S4 sleep state (hibernation), and then resume it from hibernation many times, your computer may eventually stop responding (hang) before it enters hibernation. For example, the computer may stop responding after you put it into hibernation and then resume it from hibernation approximately 300 times.
This problem may occur if both the following conditions are true:
  • The Real Time Clock (RTC) wake-up feature is turned on.
  • You use the RTC wake-up feature to resume the computer from hibernation.
