OK, this is something I mentioned in another thread, but I really need an answer so I'm starting a new thread. My new 2.4 BlackBook is having a weird screen issue. It turns off randomly when on battery power. I can still see whatever I was working on, so the display isn't going into sleep mode, the back light is simply shutting off. If I put the lid down and open it back up, the light comes back on. BTW- this NEVER happens when using the power adapter. It's always fine when plugged in.
