did you try on their forums?

Which version of Ubuntu?
Does this happen only when plugged in, or also when on battery?

A couple of suggestions for things to try:

1. Install the laptop-mode-tools package. This has some extra laptop management functionality which might assist.

2. Try the acpi=noirq kernel parameter. It has been known to fix this issue on other laptops. See the "Kernel Boot Parameters" link in my signature for information on how to temporaily test and permanently apply this parameter.

HP (along with most other manufacturers that ship with Windows) considers Ubuntu third-party software, so I would not expect much help from them.

Did you install laptop-mode-tools? Did it help?

If not, to try the acpi_noirq kernel parameter:

1. Edit /etc/default/grub as root (from a terminal window):
   

   gksu gedit /etc/default/grub

2. Change the line:
   

   GRUB_CMDLINE_LINUX=""

   ...to read:
   

   GRUB_CMDLINE_LINUX="acpi=noirq"

3. Save the file
4. Update grub:
   

   sudo update-grub

5. Reboot and test.

Can you try the following?

First issue this command to turn over power control of your devices/buses to the kernel:

for i in /sys/bus/*/devices/*/power/control ; do echo on | sudo tee $i ; done

Then try to shut down.

I am sorry, can sou help me.
How can Iadd this comman to kernel?
