If you are having trouble with your internal keyboard and trackpad, take a look at the troubleshooting steps outlined in the resource below. It sounds like you have a bluetooth accessory nearby that is trying to connect to your MacBook. First, try turning bluetooth off on your Mac, then try the steps as outlined in the article.

Nov 29, 2015 9:02 PM in response to judysingsby EladShtiegmann,Good morning! Thank you for your answer. I'm afraid the link that you've sent me does not contain steps for internal keyboard and mouse. Do you know where can I find something like that?

Nov 30, 2015 6:24 AM in response to EladShtiegmannby judysings,Hi EladShtiegmann,
I think there is an external bluetooth device trying to connect to your computer. I was suggesting you turn the bluetooth off as an initial troubleshooting step - that is the reason for the article above. A few more things you can try are to unplug all peripherals and restart the computer in Safe Mode; and to reset the computer's PRAM. Here's how:
Starting up in safe mode
https://support.apple.com/en-us/HT201262Starting up in safe mode
Follow these steps to start up into safe mode.
- Start or restart your Mac.
- Immediately after you hear the startup sound, press and hold the Shift key.
- Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac performs a directory check of your startup disk as part of safe mode.
To leave safe mode, restart your computer without pressing any keys during startup.
If you don't hear a startup chime after pressing the power key, see what to do if your Mac won't turn on.
If you're using FileVault
If your startup disk is encrypted with FileVault, you can still hold down the Shift key immediately after powering on your Mac to start up in safe mode. You might be prompted to log in twice as part of this process – first to unlock the startup disk, and a second time to log into the Finder. You can let go of the Shift key after you see the first login screen.
If an issue doesn't happen in safe mode
If an issue doesn't happen when your Mac is started in safe mode, try restarting again without pressing any keys at startup. If the issue appears to be resolved when you start up normally, it was possibly caused by a cache or a directory issue with your startup disk that safe mode fixed.
If you restart your Mac normally and an issue comes back when you reach your desktop, try disabling any login items that automatically open when you log in.

Locate the following keys on the keyboard: Option, Command, P, and R. You will need to hold these keys down simultaneously in step 4.

Turn on your Mac.
-
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the black screen with the Apple logo appears.
Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
-
Release the keys.
Take care,
