But if I do NOT hit the key during the suspending, I CAN wake it up by hitting the keyboard. After that I tried Ubuntu 16.04(runs 4.4 version kernel ) and Ubuntu 14.04 ( 3.13 kernel). And I found all of them got the same problem; Do not know if this is the right place to ask. Just a try. Thanks again. Jim -------------- next part -------------- An HTML attachment was scrubbed...
