Macbook pro windows 10 freeze sleep how to#

HereвЂ™s how to reset the NVRAM on your particular MBP: Older Macs had what's called Parameter RAM (PRAM), newer Macs use Non-Volatile Random-Access Memory (NVRAM). Before following the steps below, ensure you have no external hardware connected (so, unplug your external display) and make sure you use the built-in keyboard.

The first things I'd try are to reset both the NVRAM and SMC in that order. I would welcome any ideas on what may be wrong but also advice on where to look (log files?) to debug the situation. In all the above cases the system has to be hard rebooted by pressing the power button.

Thought there may be a conflict with the Energy Saver Display-off settings but keeps the same behaviour in all possible different settings including when choosing not to allow the display to switch off.

It has higher possibility to happen when connected to power.

Happens only after some time has passed (perhaps 15') after initiating the sleep.

Some times it wakes up, gives the login screen but freezes (spinning ball) after logging in.

Sometimes the mouse pointer may appear but the screen remains black.

Seems to 'wake up' (you can see the backlight of the screen activating) but the screen remains black.

The situation has the following observed characteristics: The above mentioned Macbook Pro Retina (Mid 2015) with SSD, running Sierra seems to be freezing most of the times, after attempting to 'wake' it up from sleep.
