When i shutdown my notebook it'll automaticaly turned on. why should i do?

it may be your power supply : if one voltage aren't good the mother board automaticaly shutdown to prevent damage
or it could be CPU, RAM or motherboard but i think that it's the PSU

In Ubuntu 9.04 click on the main icon and select Restart.

- If Ubuntu is the only operating system on your computer you'll need to tap the ESC key as the system boots.

- If you have a dual boot or multiple-boot system the menu should appear on its own.

- At the root level you'll get a boot menu. Select the one that says "recovery mode" and press Enter.

- Ubuntu continues to load until you reach the Recovery Menu.

- Arrow down to "
netroot

" which states Drop to root shell prompt with networking and press Enter.

- Now, at the root type "
password username

" (where username is the account whose password you want to change) and press Enter.

- You'll be prompted to
enter a new password

.

- You will not see the password or any evidence that you are typing.

- Retype the password. If both passwords match you'll have successfully reset your password.

- Press Enter to continue booting into Ubuntu.

hope it helps
