Why doesn't my macbook keyboard or mousepad work?

Question

sometimes my keyboard and mousepad simply stop working. I used to think it was because maybe it was overheating but leaving my macbook alone by itself for a few hours with the lid closed doesn't get it to work. since it simply gets stuck there I'm forced to hold down the power button and restart it. This has been the only thing that's been allowing me to use my macbook. I have to restart it for the keyboard and mousepad to work. Unfortunately the rate at which I've had to do this has been increasing. Today I've had to restart it 4 individual times which I know is awful but I have no other option. It's over a year old so I would have to probably pay massive amounts of money to fix it but I'm really annoyed with the situation. I'm a student and I can't keep having to restart my macbook in the middle of my studies.
I don't know what's been prompting this, there's no particular trend. It just happens when I'm watching a lecture, taking a quiz, or on facebook. My macbook hates me and it does so randomly. Why is this happening and is anyone else having this problem?

Answer 1

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time after  you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V. Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report—it will be very long and not helpful.
