Hi, I have an Acer Aspire 5749z-4148 and the keyboard on it no longer works. i am using a portable keyboard now just plugged into the USB. the mousepad still works but not the keyboard itself. the only button that responds at all is my "caps lock" key. when i push it the letter "a" apears which is strange. nothing else works. this laptop is only a little over a year old and i have malware and virus protecters and i have run many scans and it says that my COMPUTER is clean. i have tried restarting it many times without teh battery ect and nothing. iv even reset to an earlier date and still no keyboard activity. could you please help me as the problem OCCURED almost 1 week exactly after my warranty expired Please see if the solution offered on this other forum helps.

Please come back and TELL us your results.truenorthNo nothing worked. I think the keyboard itself is damaged I'm going to try and take it out and replace it on Saturday and see if that worksIf you haven't yet committed to the replacement purchase and seeing as you are not intimidated to remove the current one. Once you have it out try cleaning it well and depending what is visible look for a stuck key or something that looks out of place or bent. If not then try the replacement.good luck,truenorthThanks. I don't know much about the hardware of a laptop so I have a friend going to look at it for me because he does know alot about them. Hope the "friend" is successful and as a result the friendship is enriched  .Keep us informed as to your progress.truenorthHaha. Ya he took it apart and SEEN there was something spilt on the keyboard so the keyboard got fried but everything else is fine. He is pricing new ones for me. Great hopefully you will be back in business soon.truenorth
