My friend has a macbook pro A1278. A few days ago, his keyboard started to malfunction. Most keys are not working at all and "H" is working as delete key. He has set a login password and since the keyboard is not working properly, he is unable to login.
Today he brought the macbook to my place to check it with my USB keyboard. Quite strangely, even my USB keyboard didn't work properly. Then I plugged in my wireless keyboard. I noticed that the exact same keys that are not working on his mac are the ones that are not working on the external keyboards too (both USB & Wireless).
I looked up the internet. On similar questions, some had suggested pressing the option key 5 times to check if mouse keys was turned on. That solution didn't work for me. I also tried resetting the PRAM & SMC (as instructed on some blogs & forum posts). Not only did none of those solve the problem, it created a new problem. After the SMC reset, the macbook's fan started making a lot of noise, which it had never done earlier (according to my friend).
So basically I have 2 questions:

So basically I have 2 questions:
- Why is the keyboard behaving strangely?
- Why did the fan start making that sound (or is it not a fan and something totally different)?
