- Be patient. Some PCs take up to 30 seconds to wake up.
- Look for a Suspend or Hibernate key. Some laptops have special keys or buttons for one or both, but the user might not have noticed them if he normally uses some other wake-up method.
- Try pressing and holding the PC’s power button for five seconds or more. On a PC that's configured to Suspend or Hibernate with a press of the power button, holding down the power button will usually reset and reboot it.
- Most laptops have an [Fn] key you can press in conjunction with other keys to control laptop-specific features, including power management.
- As a last resort, remove all batteries, wait a few minutes, and then replace the batteries.

Ako nista od pomenutnog ne resava problem onda probaj da promenis podesavanaj u Power management.

uvek sam do sad morao sklanjati bateriju..
Dobar sajt btw..
