when shutting down... i usually go to the launch button on the top far right hand corner, bring the drop down menu up and click on shut down from there. From there the system go into shut down mode and even turn off machine completely, but almost
immediately will reboot again. It work as if you are trying to do a restart except the machine was turn off completely. The only thing I can do from there is to hold the power button manually as the machine tries to reboot... inorder to completely shut it off.
hope this helps... thanks

Hi Jeet,
Thanks for showing me... in anycase I execute both commands in the terminal - they both do a complete system and hardware shut down but almost immediately rebooting everything on again... Could it be a corrupt copy of ubuntu 64 that is downloaded????

I don't think it is a corrupt copy ... but question is what went wrong .. if both commands are not solving your problem ... so it can be a OS Error.
Neways Keep this question open (i'll try to check) and again download a fresh Ubuntu and burn as slow as you can. then try again with shutdown.
lets check if media is corrupt.
Cheers

one more thing if it would not help you out you can update your grub by "update-grub" command.
please let me know the result hoping it will work for you ...

Hi Jeet,
I apologize for not being in touch sooner.... In anycase just to be sure (being a noobie) I tried to add the line in the text editor (Grub.cfg) file but it would not let me chane or save the change. Do i do the change in the terminal???
Thank you

Here is something interesting... I haven't got a chance to implement the codes in the grub box... but today I was finally able to add another 3 gb memory to my machine - bought it from ebay. When I reboot the machine and shut it off (completely power down)... it worked perfectly. Of course I have 4 gb of memory now compare to just 1 gb before. Thought that was interesting and weird. Thanks a million again for your help.
