I updated OS to 4.2 last night. The wifi and some background softwares were on, and the battery was 85% before I went to bed. when I woke up 7 hours later, I cannot turn on the iPad. Even after I plug in the power, there was no response!? What should I do? Should I wait longer for battery to charge??

It's unlikely that your device worn out the battery in 7 hours. iDevices all have power protection facility built-in that will prevent this from happening; unless your device is malfunctioned. It seemed like just a system crash. Try to plug your device onto power, and hold "Home" + "Sleep" button simultaneously for 10 seconds.
