About one month ago, my Pro was dead. A soft reset restored everything. Hadn't had any problems before or since. Then, yesterday, the same thing. A half hour after the soft reset it was dead again. Tried hard reset, and it locked on the Welcome to Palm Pilot, after answering yes to delete all data question. The only way to turn it off was to remove the batteries. I have tried all of 3Com's suggestions, replaced the batteries, reseated the memory card, etc. Now, pushing reset turns on the backlight and releasing it turns off the backlight. That's all. The unit does hum when batteries are inserted. Does anyone know if it is terminal? Could the memory card be the problem? Would a new one bring it back to life? Thanks.
