I charge my macbook everyday because it empties very fast i find. My battery status is 99-100%(istatpro) and i also keep it at low brightness so that my battery runs out less fast. Once its charged I unplug it so that I dont ruin the battery as quickly. I have also realized that i can have 80% battery and close my macbook(put it on standby) and come back to it at the end of the day at 20%. Its obviously the standby light flashing all day and its nuts! IS THERE A WAY TO STOP THE LIGHT. I dont want to turn it off because i come in once and a while to use it for 10 minutes about 5 times a day. Its is 1.5 months old and i did calibrate it when i got it and one month after. How is your macbook doing? Does your battery run for a long time. any answers and comments are appreciated Thanks, mackid16.
