Still having issues with MacBook Pro

Hi everyone,

I recently cleaned my macbook with foam cleaner a few keyboard keys stopped working, I have replaced the keyboard and backlight but I am still having the same issues, I have tried a PRAM and SMC reset to no avail.

Any advice would be appreciated

Regards

Have you tried an external keyboard?
See if that does work then go from there...

Hi

Thanks for the reply

I have tried an external keyboard and this works fine

Regards

I'm trying to figure out exactly what it is you did. The machine was working OK before you sprayed foam cleaner on the keyboard and maybe elsewhere? If that's true, the foam cleaner likely got down onto the logic board and may have caused a short. Liquids and electronics do not mix.

You stated you replaced the keyboard and backlight but have the same issues. What issues are you having and which model MacBook do you have?

Keys on the keyboard aren't working exactly the same as it was before I took it apart

That's a Mid 2009 MacBook Pro 15" not a MacBook. Anyway, since an external keyboard works OK and you replaced the internal one, it does sound like a logic board problem. What I would do is remove the new keyboard and cable carefully and check the connector on the logic board. There may be some corrosion on the connector or maybe some foam got down into it. Buy a can of compressed air and blow into it and also around the area where the cable plugs into.

Bit late but never use any type of fluid cleaner including foam which is simply H2O and detergent - both damaging to electronics.
