    hi all,

    Twice in the last few weeks my MacBook Pro (15inch i7, mid 2010) has lost power and when booted up again the time and date has been reset to 00:00:00 and the earliest date possible. It also looses the wireless connection password but i think this may be due to the dates conflicting with the date my Keychain was created.

    In addition, after these power losses and also intermittently at other time the charger doesn't work first time and i have had to try different sockets to get it to function.

    My first thought would be some sort of power surge or fault in the charger that causes it. But i'm not sure if that is even possible.

    Any thoughts would be much appreciated.

    I think it may be your PRAM battery. Try to do a pram set and see if that works. Other than that, I think you may need to see Apple.

    Yes, it's look like a coin battery dead, try send to the apple shop to replace new coin battery.
