Procedure you use when your laptop won't shut down

Toshiba laptops, are fair enough in quality but sometimes this sort of problem may arise that computer does not shut down properly.
To forcefully shut down ,one step you can follow is what SlipFallGuy has suggested is to use the start button for 5-10 seconds. But again, this may result in different problems and always results in safe mode start up to repair inconsistent state of last shut down.

Secondly, first check whether your computer is responsive or it is in a hang state. In any case you can use the keys CTRL+ALT+DELETE together to open the windows task manager. You can then check for those process which are unresponsive. This can be found in the application tab inside the windows task manager. Try to click end task by selecting those process and then wait again if the computer is again responding normal or not. If at all it is not responding then you can check for increasing other options which can increase you personal computer's performance. This are already installed in you windows machine such as disk cleanup , disk fragmentation etc. This will release some bad memory and mad sectors from your computer's memory.

Try this options and keep updating your laptop's state so that we can suggest better options if possible.
