Hello to all Macs
I've got a similar problem with my Mac. Some days now I am experiencing this:
I work on a fully charged battery and suddenly the computer "sleeps". Only one led light on the battery cover flashes. The computer "awakes" only if I connect the power adapter. Then the battery indicator on the right upper corner of the screen shows that the battery has to be charged, and it charges fully in a mater of minutes. This hasn't happen before and I am thinking that the battery may be drained and needs replacement. Any suggestions? I've already done the SMC reset as suggested in the previous message by Lyssa.
