I am facing strange issue on my Lenovo T61P. It is having windows 7 running on it without issue but suddenly it refuses to shutdown when running on battery. It simply shuts down the laptop & after a moment restarts it.
Before this issue laptop was ON overnight ( 7-8 hours)with power adapter plugged in which I found very hot in the morning.
After this lncident, if I try to shutdown or hiberanate it does that & then restarts the laptop on its own without pressing the power button.
