Hi all, went through an airport security scan with macbook. Fully charged, kept in soft case, placed in plastic tray box. One hour before at hotel all worked fine. Ten minutes after scan try to start macbook (on battery power) and it would launch to desktop screen then shut down. Tried 3-4 times same issue (like if the battery were dead) Hooked up to power cord and same issue. I was in Europe when this happened. Got back to the US (8 hrs later) tried...same issues. Took out the battery, replaced same, and let it charge over night. Now it is working. HOWEVER when I go to bookmarks and try and link to ANY mac site I have bookmarked I get sent to a mostly blank white page with an ad in the upper right corner. Could be related to other issue or just something different. This issue with the charge/operation after going through security scan has happened once or twice before. Any thoughts, advice help greatly appreciated.
