I'm using win 7 and I've had a strange problem. After browsing the internet and using Skype, I wanted to shut down my laptop because the battery was running low. But, no Shutdown Button. I managed to shut it down by using task manager ctrl+alt+del and power(shut down) button from here!. After starting the pc again, the button re-appeared.
I do not understand what caused that. Should I run the sfc /scannow command or something else...
Thanks in advance,
