MacBook abruptly turn off I have a MacBook Model A1278. After a replacement of the battery in a moment of low charge (like 5-7%) the laptop is abruptly shutting down. As far as I remember it should be like a "sleep mode" or something like that.

Additionally, in a process of normal shutting down that I do by myself with any percent of charge, I hear some clicking sounds from the HDD that means that the HDD was turned off incorrectly (in a moment when read head doesn't stop in a parking zone).

For the first try of repair I did reset of PRAM and SMC but it doesn't help. As a result, either PRAM or SMC didn't reset (how I can check it?) or there is something else. Any suggestions?

UPDATE: Thank you everyone for attention! So here is more information:


I Have A1278 Mid-2012 model.
I've using macOS 10.12.2
After the command syslog | grep shutdown I've got the result in only one line


  NOTE:  Most system logs have moved to a new logging system.  See
  log(1) for more information.

I'm trying to fix the abrupt shutdown. There should be a something like sleep/hibernation mode when the battery charge is lower 5% instead
I've tried to calibrate battery with no luck
How did you reset the SMC?

It's not clear exactly what model of MacBook you have, but the process for resetting the SMC can differ. I have included two sets of instructions below that could apply to you - select the one that matches your Battery type.

For MacBook Pros, MacBook Airs, and MacBooks where you can’t remove the battery on your own (i.e. it's a built-in battery), here’s what you do:


Shut down your computer
Keep the MagSafe adapter (power cable) plugged in.
Press at the same time shiftoptioncontrol (on the left side of the keyboard) and the power button
Let go
Turn your computer back on with the power button.


For MacBook Pros, MacBooks etc that you can remove the battery from, here’s what you do:


Shut down your computer
Disconnect the MagSafe plug (power cable) from the computer
Remove the battery
Press the power button for 5 seconds and release
Put the battery back in
Reconnect the MagSafe cord (or power cable)
Turn your computer back on with the power button
