My Mac just goes to sleep mode random time and then it tells me to plug it because I don't have battery, but then after plugging in it just wake up with whatever battery percent I had so what can be the reason and how do I get fixed?
MacBook Pro with Retina display, iOS 7
These additional steps may help identify or resolve the issue:
- Reset the SMC.
- Reset NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
- Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
- Try to isolate the issue by using another user account.
If you still see the issue, contact Apple Support.
