In order to fix it in that case, go to Device Manager -> Network adapters -> “broadcom” device -> Properties -> Power management -> Uncheck “Allow device to wake computer from sleep” as shown in the image below. In order to reset the PRAM and RAM (NVRAM) you will need to press Command + alt or option key + P + R – all these keys at the same time – Hold the keys down until the computer restarts and you hear the startup sound for the second time and then release the keys.įor some macbook users this problem was due to WiFi adapter not allowing and waking up the computer when it tries to sleep or hibernate. Hardware settings are stored in a thing called “parameter RAM” (PRAM) so some people solved by flushing these memory areas. When I went to apple support forums some of the people fixed this by resetting both PRAM and the nonvolatile RAM (NVRAM) of macbook pro. Once I started inspecting the issue, after searching a bit I came to know about other users facing the same problem who were running windows 7 on their macbook with bootcamp. Sometimes this causes it to wake up in Windows mode, sometimes it reboots completely, sometimes the battery has been drained and Windows has to restart and gives the message that windows was not shutdown properly. I often end up having to press the power button just to get it to wake up.

It happened like I close the laptop and leave it for more than just a few minutes, when I open it back up, it does not awake immediately. I never faced any issues in running windows 7 but recently I started facing a strange issue when macbook pro suddenly stopped hibernating and also did not enter sleeping mode when I tried several times. I have been using windows 7 on my macbook pro for around 5 -6 months now, in dual boot configuration with Mac OS with the help of bootcamp which comes preinstalled in any every macbook pro in mac os.
