>>>>>>>>>>> I was working on director mx with battery power, without me knowing the battery percentage dropped to 0 % (no pop up window) suddenly the mouse disappeared and the system freezed completely I tried closing the lid the light went off and opening it back the light came on but still no mouse, I tried then plugging it to the ac adapter still noting the lid was still on but no mouse movement no battery charging, so I had to shut down the computer (prolonged pressure on the power button) and now every thing is back to normal. Is this a normal behavior of the new operating system (10.2.6) <<<<<<<<<----------- The battery in my powerbook ran down while "sleeping". It wouldn't startup, on wakeup, after a week or more of sleep, so I suspected that the battery had run down. I plugged in the power adaptor and it restarted, but the startup took about twice as long as usual. So, if this is typical, then restarting after a battery is run down will take a longer time. It all worked fine after the restart. Jerry
