A few Months back in a cold March day, I bought my MacBook Pro. Immediately after the purchase (approximately 10 min) my laptop’s “i” fell out! At this moment I knew that my agony had just begun.
Fast forward to this Sunday and the Mac does not fail to be a pain in the funny bone. Out of nowhere, very unexpectedly, the keyboard and trackpad stopped working! This was specially a pain in the but because I had a midterm due on Tuesday and this lack of ability to do work was especially stressful. I tried turning the laptop on and off a couple of times, but nothing worked.
The first solution was to borrow a mouse and USB keyboard from school. But this temporary solution sucked and was very inconvenient! So I did what anyone would do; search the internet for solutions. I found out some interesting insight as to why the keyboard freezes. According to a couple of forums I read, there seemed to be an indication that there was some type of software problem.
The second solution may not work for everyone but it definitely worked for me. I consider this to be a temporary fix until I get a window of time when I can take the laptop for a check up.
The fix was to take out the battery from the laptop for a good 5-10 minutes.
after that time, I turned the laptop back on and the keyboard was back to normal.
good luck.
