Keyboard keys S to L not working
Hi
I have an MacBook Pro late 2011 that has served perfectly until now. The keys from S to L (mainly second row of the keyboard) stopped working. They are lagging or not responding at all. The problem can be absent but then reappears. External bluetooth keyboard works ok. I have refreshed memories and done all the routine tasks. What might cause this? Loose cables, dirt, liquide etc.? How to test different options and diagnose? Hardware test didn’t find anything.
Thanks a million for anyone who can help me!

I haven't yet received the new battery but in the meantime I have recognised that when starting again after longer time eg. over night I wait for couple of minutes and the keys are sort of warming up and after few minutes they work quite ok at least for a while. Still something related to the battery?

Hello
I have changed the battery now and unfortunately that didn't solve the issue. So, next step will obviously be replacement of the whole keyboard, which is not an easy task and I have to rely on service (expensive in relation to the age) or consider to buy a new Mac. Sad to conclude this.
Questa è una buona domanda?

What can happen is the battery swells up pressing on the keyboard lets see if you need a new battery first.

I'm afraid battery is not the cause because problem exists even if connected to the grid.

@fixer66 - I fully understand, trust me! It's not that simple. Lets get the output please.

Pls explain how the keyboard uses battery and how poor battery could restrict key functions? I'd really like to fix this dysfunction otherwise than by replacing keyboard or the whole top case.

I need to see the CoconutBattery output to know. Or you can just jump and replace it! MacBook Pro 13" Unibody (Mid 2009-Mid 2012) Battery and here's the guide: Sostituzione Batteria MacBook Pro 13" Unibody, versione fine 2011
This is a common issue!
