    Has anyone else experienced this? It just happened to me for the second time in the last few months. Upon turning my Mac back on with the charger plugged in after the battery has died, upon startup, Mac OS X warns me that the date has been set back several years. Also, it doesn't remember my preferred wireless network.

    I have had the same thing happen in the past. Apple was no help in what the problem is. Just a pain sometimes when you are in a hurry.

    Here is to hoping someone has an answer!

    If it were a PC I'd say CMOS battery was dead. Since Mac's batteries are built in, that is obviously not the case, unless you are running every last ounce of juice out of the battery. That's extremely doubtful.

    Have you reset PRAM and SMC? That is most people's go to answer for weird occurrences like this.
