Affected system Windows 7 Ultimate 64 bit

Symptoms : The Notebook doesn’t go into standby and the power button flashes continuously instead of blinking (normal behavior)  , and the Num lock and caps lock work but don’t flash light .

The cause of the problem is the Energy management utility that comes with system drivers , just disable it from start up and restart then uninstall using IOBIT uninstaller , then restart and install it again .

Don’t forget to create a restore point before installing the energy management again .
