When you shut off your PC do you:
1) Give it enough time (could take from 1 minute to 10 minutes) to shut down completely (easy sign is if the fun continues to run or lights are on)?

2) Clicked Hibernate or Sleep OR closed your laptop screen before it completely finished shutting down (this could put the PC to sleep and it would remain on, so the lights would remain on, until you woke it by moving a mouse, flipping the screen back and forth for a bit or pressing the start button (not holding))?

3) Have it plugged in (depending on the model, a light might stay on if it is charging even if it is not on(probably not this one since you said it turns off after a Hard shutdown (don't do this since this damages your computer and will make it break down after continued use)))

Try going to your power option in the control panel. Make sure that hibernate is disabled, change what power buttons do. Make sure when you press power button it is set to shut down. Choose when computer sleeps as never.

It could mean your power supply is about to go. Unplug it and reboot the computer when you get into windows look for power options in the control panel ! Set it to a different scheme such as always on. Then try shutting down to see if it works.

Your are not "shutting down" the laptop. It is going into "Stand-by" mode.

#1:
When you want to shut down,
select [Start]
then select "Shut down" and not "Stand-by"

The power button will also work.
#2:
When you want to shut down,
Press the power button and nothing else.
The laptop will log you OFF and "shut down"

vsc shuts down any time check engine light comes on. repair engine light problem, reset computer monitoring system and vsc light will go off. must scan computer to pull codes for check engine light and go from there.

try using a different monitor, borrow one if you have to, if the monitor works on your computer, then it simply means you need a new monitor. As far as the computer shutting down, it may be recording the bad monitor as an error in the loading process and automatically shutting down.

If you log off you only close your user session under windows, not turn off the computer.

If you suspend you turn off almost everything in the laptop like hardwire, cd or dvdrom and most peripherals but the computer stays on the consuming power.

If you hibernate what windows does is to store all in memory in a temporary file in the hard drive and turn off all the computer so when you turn it on again it will be as you last session with all your programs and documents you left open.

And if you turn off the computer it will close all your programs, close windows and turn off all the hardware.

  Hi,     I think you might have a cooling issue with the CPU (Main Chip). If the CPU is getting Hot it will shut the system down preventing damage. Check the  inside of the case and be sure that the fan for the CPU is functioning. You might also have your power supply checked as well...
