Unresponsive trackpad and keyboard
Hi. I own an early 2013 MBP with Retina Display currently running on Yosemite 10.10.5. I went out of town a couple of days ago leaving the MBP in Sleep mode. Having done this numerous times in the past two years with no issues whatsoever I didn't think twice about it. It was placed in a sleeve during the duration of my trip. Upon my return, when I lifted the lid up, the screen came on asking me for my password. But, both my keyboard and trackpad were unresponsive. I dismissed it as being a rare glitch and shut down the computer using the power button. When it restarted, the keyboard seemed to be working fine, but the trackpad was still frozen (the cursor remains frozen). After almost 12 hours of trying various things to fix this (but to no avail unfortunately), this is what I have seen:
1). When I close the screen( close the lid) and re open it after a minute or two, both my keyboard and trackpad are unresponsive. I have to then restart or shut the computer down in order to get the keyboard to work. The trackpad is completely frozen in either case.
2). even though the keyboard works , it's sticky and it lags. I have to press the same key several times for the letter to appear on screen. I am typing this message on my iphone because it was practically impossible to do this on the MBP.
3). Apart from these two things, the computer seems to be working fine. I was able to use Skype for over an hour yesterday.
4). The cursor moves when im using a USB mouse. The computer also gives me intermittent messages about connecting a bluetooth mouse or keyboard when I don't own either one of the two and neither have I ever connected them to it.
5). I have not yet tried using an external keyboard.
things ive tried till now:
1). I've tried an SMC reset many times now.
2). A PRAM reset.
3). when the problem first occurred, I was not running the latest version of Yosemite. Thinking that it might be a software bug, I somehow managed to update to 10.10.5 but that didn't fix anything either.
4). I re-installed Yosemite via Apple Recovery Services. Even whilst doing that, the MBP showed me images of how to switch on my Bluetooth mouse or trackpad which makes me wonder whether its just not detecting the trackpad (if that's even an issue). Reinstalling Yosemite did not work.
5). after reading all possible threads about this issue, I even checked the underside of my
MBP for signs of a swollen battery but I can't figure anything out.
this is the very first time in over two years that my MBP is giving me such major issues. I didn't even face this bug in 2013 when it first appeared. Needless to
say I'm quite frustrated and feeling very helpless because I really don't know whether it's a software bug or a hardware issue. And if it's a hardware issue, how can it crop up suddenly without it being even used.
Any and all help will be greatly appreciated.
THanks.
