East of the Sun, West of the Moon


I suppose it was time

Filed under: OS X,Technology — Erwin @ 4:20 pm

I’ve had an unpleasant week of unpredictable behaviour from my MacBook Pro where it would simply power off while the battery still looks like it should have enough charge (typically over 10% and under 40%), several attempts to fully and utterly drain and then recharge the battery, resetting the SMC (System Management Controller) data to make sure there is no anomalous data there. This forced me to draw the conclusion that after 476+ cycles it may not be entirely unexpected that the battery is due for a replacement!

The MBP has been here since July last year, so nearly 15 months now. If you’ll do the math with me you’ll see that I’ve had the battery go through at least one cycle per day, on average. To have the next one last a bit longer I’ll have to try and keep it on the adapter, I guess. I was already trying to do the drain it fully, once a month thing, but will also try to do that more consistently.

Any other suggestions?
