when I click suspend the pc goes in susend mode for some seconds and then it exits immediately

What do you mean by 'exits immediately" ?

  1. Does it transition from suspend to powerdown ?

Or

  1. Does it immediately wakes up after suspend ?

If the latter, could it be this ?

copypaste the complete block below in your terminal and press enter:

cat <<\EOF  |sudo tee /etc/rc.local
#!/bin/sh -e
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

echo 'GPP0' > /proc/acpi/wakeup
echo 'GPP8' > /proc/acpi/wakeup
echo 'GP12' > /proc/acpi/wakeup
echo 'GP13' > /proc/acpi/wakeup
echo 'XHC0' > /proc/acpi/wakeup
echo 'PS2K' > /proc/acpi/wakeup
echo 'PTXH' > /proc/acpi/wakeup
echo 'PT29' > /proc/acpi/wakeup

exit 0
EOF

sudo chmod a+x /etc/rc.local

If it's done, reboot.

Thank you, Thom.

Could you explain a bit about what that script will do?
What are all those codes intended to set?

It disallows those pieces of hardware to keep the computer awake as explained here:

The above blob of code will create an rc.local that will contain the commands to switch the hardware that's keeping the machine awake, to a state that it's no longer keeping the machine awake. In this case 8 (parts of) controllers that get this treatment.

Removing this rc.local will undo everything.

Usually echo 'GPP0' > /proc/acpi/wakeup is enough, but not always.

If the core above works, it's always possible to fine tune. If it doesn't, it's easy to revert.
