Waking from sleep mod

Some things that caused this same issue for me were:
1. I had a very sensitive mouse and even though I was in bed, the mouse would move very slightly, but not noticeably, and that woke my computer up.
2. I have also had problems with USB devices (keyboards, mice, and wireless adapters). Sometimes, and usually over a period of several years, the ports on the computer will become loose (or something), causing the USB device to move around a little if the desk gets bumped. This caused my computer to play the "USB device removed and inserted" sound, and it also caused my computer to wake from sleep.
3. Check out your Scheduled Tasks. You are bound to have a few if you are not the type to manually delete them all. If updates are scheduled to run in the background, this could also be waking your computer up. Look out for Google, Apple, Adobe, and Java in particular. I always see them in Task Scheduler. And somehow, Google update keeps reappearing.

Disable sleep mode or update firmware. Cause this is a firmware bug.

Some people snore at night but still wake up in the morning feeling like they slept well. But for some people heavy snoring leads to side effects such as;

1. waking up feeling exhausted the next day

2. difficulty concentrating

3. increased risk of high blood pressure, stroke etc

Snoring can also seriously impact on a partner's sleep as the noise can often stop the person sharing the bed from being able to sleep well.

If you computer is in sleep mode, you don't need to restart it simply click the left button on the mouse

Unplug the display from your macbook, and restart your macbook, when it's fully restarted and you are logged in, plug the display back in, then check to see if it is detected. Macbooks don't like to be put to sleep (shutting the lid) with a display connected, this causes issues with display detection. So always unplug your display and wait about 5 seconds before closing the lid on your macbook, and when you open the lid, wait another 5 seconds before plugging in your display. The only time it is acceptable to leave the display plugged in when you close the lid is when you plan to use the macbook in clamshell mode, this is done by plugging in and configuring your display, shutting the lid, and then "waking" the macbook from sleep mode with an external mouse (wired or wireless will work). That will start the macbook using the external display as the main display, without even turning on the macbook built-in display. Never connect or disconnect an external display when your macbook is off or in sleep mode. Have a nice day.

okay this line of mac have bad logic boards what happends is the capcitors on the logic board swell and cause freezing issues if you have apple care use it because this repair will cost $$$ to fix..

I have seen this caused by having a mouse plugged into mine. I have removed the mouse and touch the touchpad and it has come up from sleep.

That very well may not be your problem.

Here is the procedure that is recommend from Apple to help with the not waking from sleep problem. I included both methods as it is not clear which macbook you have. I also included the link to the article at the bottom.

The System Management Controller is an integrated circuit (computer chip) that is on the logic board of the computer. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others.

MacBook (13 inch, Late 2008), MacBook Pro (15-inch, Early 2008), and MacBook Pro (17-inch, Early 2008)

1. If the computer is on, turn it off.
2. Disconnect the AC adapter and remove the computer's battery.
3. Press and hold the power button for 5 seconds and then release the button.
4. Reconnect the battery and AC Adapter.
5. Press the power button to restart the computer

Note: Starting with MacBook Pro (Late 2008) and MacBook (Late 2008) models, you may instead use the reset method for MacBook Air (below) to reset the SMC. All earlier models of MacBook and MacBook Pro must use the method described above, which involves removing the battery.
MacBook Air and MacBook Pro (Late 2008 and later)

1. If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
2. Connect the power adapter to a working power source.
3. On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
4. Wait 5 seconds and press the power button to start the computer.

Note: You must use the keys on the left side of the built-in keyboard.

Hi, could be simply your computer is going into sleep mode and not waking back up. try changing your screen saver option to not hibernate or sleep.

You should check your "Energy Saver Settings", and your "Bluetooth Settings" to see if there are external causes for its waking.
It also might help to change your "Energy Saver Settings" to "Better Energy Saving" while you're not actively using your Mac. At least that way it'll turn itself back off.

I have had similar problem. I found, by trial and error, that using Windows hibernate mode actually works every time! Windows makes a "System screen shot" and stores it on hard drive and then powers off. Just be aware that you must ensure enough hard drive space for this. I am using this mode every day now.
