Do I need to unplug the magsafe adapter when my macbook is in sleep mode?

[brotherandy]

This may seem like a really simple question to someone who is familiar with Macs, but I am brand new. When I hibernated my old Vista laptop, I always unplugged the power adapter (it go too hot if I left it plugged in overnight). With the Macbook (Macbook Pro 13, mid-2009), should you leave the Magsafe Adapter plugged in, or is it OK to put the Macbook into sleep mode overnight, and leave the charger plugged in? I don't want to deplete the battery (that flashing LED makes me wonder what kind of battery draw there is in sleep) by putting my laptop into sleep mode for eight or so hours, and not have the charger plugged in. Any answers would be really appreciated. Thanks.🙂

No, you can leave it in. It charges the battery.

Either way it's ok.

But won't the power adapter's life expectancy be shortened by being plugged in all the time?

It will stop charging when it is full. I leave it plugged in when it's closed, and it is always cool when I go to open it. 🙂

No.
