- Install HWSensors or iStat Menus (or any respectable, updated sensor monitoring app)
- While the magsafe is plugged in, check sensors values. Are they updating/changing? Notice the graphs.
- Unplug the magsafe connector.
- Do your sensor values seem to "freeze." Notice graphs will draw horizontal line(s).
- Replug magsafe. Values begin updating again.
I have reported this to Bjango support (iStat Menus developer) and they have concluded that this is something beyond their control and only Apple can fix it.
Any ideas?
