I've had my m1210 laptop for about 18 months and am now beginning to experience extremely short battery life (< 20 minutes) -- which is apparently typical for a battery that age and I guess it's time to replace it.  However, today my 65watt power supply suddenly stopped working:  when I plug it in, I get a momentarily green LED on the brick which then goes black.  (This happens whether or not it is plugged into the m1210).  Is this indicative of a failed power supply, and is the only fix for me to replace it?

Thanks!
