Can I reset SMC manually?
This question is archived. No new answers are allowed, and only the question's owner may edit it.
My MacBook keyboard and trackpad started to malfunction. My keyboard only responds to a few keys. I tried doing a SMC reset but it does not work. I tried a PRAM reset, but it does not work. Is there a manually button to reset the SMC? Will an external keyboard work? I've already spent 10 hours on this and have tried all the Apple instructions, so I'm looking for new ideas on what to do.
