I just recently got rid of my iBook G4 for a MacBook and I've been running into some problems on the new machine. One issue I've ran into is that my MacBook completely shuts off when the battery has been drained. My iBook, with a 3 year old battery, would always save whatever I was doing before the battery drained. This battery is under a year old and the Battery Condition is "Good" in System Profiler. I've tried repairing permissions but it hasn't fixed it. Another issue I've been having is not being able to get an IP address from a specific access point on campus. It connects to the access point but then says it has a "self-assigned IP address" but there is no internet connectivity. My iPhone connects without a problem as well as the rest of the Macs and PCs in the room. On any other connection (including mine) it connects fine and obtains an IP address automatically. Anyone have any possible solutions or similar issues? Thanks in advance.
