Guys, I doubt that the iBook was trying to connect to a WiFi network in China, child porn or not. Wifi networks are generally limited to a couple of hundred feet diameter.
The iBook will only find a wireless connection to a local Wifi hotspot. The owner of the site can name it however he chooses and may have chosen the name "jdnetwork" because his name is John Davis and its his network.
Thanks VERY much for your replies, Swordmaker. Really appreciate it. I’m going to advise he pop the battery out and clean the contacts, as you suggested. Hopefully that’s the problem and will allow the computer to turn back on again.
However, when he was on the phone with Apple tech. support, they told him to hold in the power button for 10 or 15 seconds (as you suggested as well) in order to power down the machine. Doing this didn’t turn off the machine, unfortunately. That’s why he ended up popping out the battery in the first place.
Thanks again very much for your help. Fingers crossed it’s just the battery and no viruses!
