Thank you for you help to resolve this trouble. I really appreciate it.

Outputs of "upower --dump" can be found in attachments.
   * Battery_mode_after_boot - laptop has been turned on with unplugged AC
power;
   * AC_mode_after_boot - few minutes after log in session I plugged AC
power. Nothing changed;
   * AC_mode_after_boot_changed - after about 5 minutes screen brightness
was increased and AC power mode was activated;
   * gpm.gconf.values.txt - gpm settings dump.

Why does it takes core so much time to switch between power modes in Ubuntu
10,04?
Please help me solve and correct this bug.
