How else do I turn off windows when computer has black screen.


Likes # 0

My wifes laptop has developed a problem. On booting it starts with the "Windows starting " logo and then goes to a black screen and goes no further. It looks like the hard drive is still flashing away giving the impression that underneath it is still working but no picture. We want to use the repair disc that came with the laptop but because we cant see anything to shut the computer down via windows we are having to use the power button and therefore it prompts to start up again in safe mode because it was shut down unusually. We want to close it down completely and let the repair disc do its work on boot up from fresh start. Because we cant see anything on the screen to initiate shut down via windows is there another way of shutting down completely for the above reasons. Also do I need to press f2 and tell the system boot from the cd (repair disc) or can I leave settings as is and it will do it automatically. Answers appreciated asap. Many thanks

On many laptops pressing and releasing the on/off button acts as a re-set but if you hold the power button down for 5 to 10 seconds the machine will turn off completely.

Thanks chub_tor I just tried that but it opened up again in windows recovery window again and then automatically starts up the windows sequence which as said before leads to a black screen. I sense the desktop is there under a black screen if that makes sense but I cant obviously make use of it. I may be wrong though. Any more advice. Cheers

OP system? assuming you have Vista or W7 as you are referring to repair disk?

Boot from the DVD and select start up repair from the menu details to follow.

However it might be worth looking at a couple of other things first.

Check the lid switch isn't stuck down (screen switches off when laptop closed)

check the screen isn't set for external monitor Fn key = one of the F keys(usually blue square symbol) press once for swap to external, again to swap to lcd + external, and again for LCD only.

sounds as if your screen is working because you can see messages before windows starts.

Vista / W7 repair options

You need to look at Windows Repair Your Computer options.

  • Startup repair - This automatically fixes problems that are preventing Windows from starting
  • System Restore - This will Restore Windows to an earlier point in time
  • Windows Complete PC Restore - This will completely restore your entire PC - programs, system settings and files - from a back up that you have previously created (Available in Windows Vista Business, Enterprise and Ultimate editions only)
  • Windows Memory Diagnostic Tool - This checks your computer's memory hardware for errors
  • Command Prompt - This opens a Command Window

With the Complete PC Restore Option you must have made a backup of your system, either on your hard drive or on a set of DVDs, in order to use this option. If you don't have a backup then don't use this option

How you access the repair options will depend upon whether you have a Windows installation disk or whether your operating system came pre-installed by your PC manufacturer.

Pre-Installed Options NOTE

If no repair options are available your PC manufacturer may have replaced the tools or customised them. Check your Computer Manual before proceeding.

1/ Start your PC

2/ If your PC has one operating system Press and Hold the F8 key as your PC starts. If the Windows Logo appear you will need to start again

3/ If you have a dual boot system a Boot option menu will appear. Highlight the Vista operating system and Press the F8 key

4/ In both cases, if all has gone well, an Advanced options screen will now appear

5/ Highlight the repair Your Computer option and Press Enter

6/ Select a keyboard layout, and then Click the Next button

7/ Next select your user Name and Enter your Password, then Click OK

8/ The recovery options should now appear

Windows Installation Disk NOTE

1/ make sure your PC can boot directly from the Windows DVD. Obviously, most modern PCs can. With older machines you may need to check the PC's BIOS

2/ Start the PC

3/ Immediately insert the Windows DVD into the DVD drive

4/ A Black screen will appear with the words 'Press any key to boot from CD or DVD'

5/ Press Any key to start the booting process

6/ A new screen will now appear with a progress bar. The legend say's 'Windows is loading files'

7/ After a few minutes the Microsoft copyright window ill appear and another small progress bar will be visible

8/ You will next see a Blue curtained screen

9/ After a short while the Language option screen will appear

10/ Select your language and keyboard language and the Click the Next button

11/ At the bottom left of the next screen - the Install screen, Click on the Repair Your Computer option

12/ The System recovery options will now search for your Windows installation

13/ Once the Windows installation has been located, Highlight it and then Click the Next button

14/ You are now presented with the set of recovery options

15/ Click on the Option you require and follow the onscreen prompts

Start the machine and get into BIOS. Check that the machine has the CD drive set as first boot option. Boot the machine, insert the disk, power off and back on and the machine will boot off the disk. You can then carry out the startup repair.

To close/shut it down completely using the Power button you have to continue to hold it pressed in until you hear/see power shutdown. This may take up to 15-20 seconds before it switches off.

Try use external desktop PC monitor and see if the display problem can be corrected.

Try reseat the HDD.

The other way of powering off the laptop mandatory is unplug the AC adapter and remove the battery.(this method is not suggested unless some situation like yours that cannot power off the laptop by pressing the power button over 5 seconds.)

another suggestion, when we see the laptop reboots, pressing F8 key and see if there is a boot menu shows up. If so, select Lask Known Good Configuration and hit enter. This will load the last working hardware profile and the may correct the display problem.

Hope this helps! Bill
