Battery discharging while plugged in. Both under heavy load and sleep

[vmachiel]

Hi Forum,

I have a macbook as discribed in my sig. Today, I started out with a full charge and it was plugged in. It first discharged while I was gaming, and recharged when I stopped. Later, I put the macbook to sleep, kept it plugged in and came back to find the battery at 50%.

What could be causing this and what should I do?

Discharging during gaming is normal as for not charging did you try unplugging the charger and plugging it back in?

Yeah I did. But it's just weird to me that a fully charged laptop in sleep mode, loses half its charge

You should check Activity Monitor to see if you have a process that is preventing sleep and is draining system resources. Also, make sure there are no problems with your MagSafe adapter or its connection to your Mac. As for the battery draining while gaming, it's normal for your MBP to draw power from both AC and battery during periods of extreme demand, such as gaming or other multimedia operations. This can cause your battery to stop charging or even drain, even though it's plugged in. Read the AC POWER section of the following link.
