Ubuntu Doesn't Shut Down

you tried turn it off with power button

That is a software issue with the OS. Was it always like this? If not, try a system restore to some time in the past when you know the unit was working fine.

Make sure the VGA cable is properly inserted to your pc and monitor

you are cold booting the pc always shut down normally when you shut down just useing button it will eventually corrupt the system I have several computers and never shut them off at all unless installing new hardware if you get a keyboard with the specific button just for the sleep mode this problem will clear up but if you shut down normal it will work rite

All projectors take a bit of time to shut off, when pressing the power button it first shut off the lamp, than the fan runs for some time after to cool down the lamp, have you waited long enough??? if after a minute or two, if it is still running than try pressing the power button on the unit it self, it could be a defective remote as well.

Cheers!

press alt+Shift+ctrl to open the task manager and then choose shut down option from the task manager menu

Sounds like it is stuck in hibernate mode. Hold the power button down for 5 seconds and try to start it again. If it doesn't start remove the battery, unplug the laptop, hold the power button down for 60 seconds. Now plug in the power supply but leave the battery out. Turn it on. It should start now and you can re-insert the battery.

hi,
if you forget your lock code try to reset your phone in ths easy way...but i want you to know that all of your data will be deleted...

here is the instruction...

1. Turn the power off. If your Samsung Galaxy S is frozen, pull the battery out and
reinsert it
2. Hold the Volume Down button
3. Press and release the Power button
4. You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage,
and Simlock
5. Select Clear Storage by pressing the Volume Down button
6. Press and release the Power button
7. Now simply confirm your decision: Volume Up for YES and Volume Down for NO

If the above procedures doesn't work, use this second method below,

2. Now press the Volume up, Home and Power button together.
3. When Samsung Symbol shows up release the power.
4. Then there is a boot Menu. Use the volume up/down to choose and home to select.
If YES is selected, all data including third-party applications will be deleted from your
Samsung I9000 Galaxy S. Once the wipe is complete, the phone will reboot to its factory
fresh state.

i would say for some reason your dvd player is not compatible from now on with that brand of blank dvd!


get the firmware update from the brand website all you do is download the file burnit on a cd and put it in the dvd player should fix most and eventual problems
