Both trackpad tap and click are unresponsive on system suspend/resume (i.e. after closing and reopening the lid)

Question

Hi all, it's a while that I noticed a strange behavior.
Every time I suspend the System by closing the lid, I'm not able, after resuming to use the trackapd correctly.
Actually, on resume, single tap and click seems like not working.
The only way to have them back on track is restarting the system.
Any idea?

fiveinchwrench:
I used an electronics cleaning wipe to clean the case after I shut down.
Did you sprey it on directly or did you spray it on a cloth and wipe the keyboard and trackpad? If you did, it may have penetrated to the contacts. Incidentally, all you need is a damp, lint-free cloth to clean your computer.
Could the wipe have killed the trackpad?
Possibly.
Would it have damaged the logic board also?
If you sprayed a lot of stuff on, it may have penetrated to the logic board. However, if the computer was shut off, and you are still able to start it up, it should be okay.
If the only problem it the trackpad and clicker, you can try lifting the upper case and cleaning the contacts etc. If still not luck, you may need to purchase and install a replacement upper case.
Unless you feel comfortable getting under the hood and seeing if you need to clean up a bit, I suggest that you take it to the Apple Authorized repair and have them take a look.
Good luck.
