I have a Lenovo 3000N200 laptop running with Windows XP Pro. I recently installed windows on this laptop due to some problem. Everything is working fine now except Standby and Hibernate mode problem. I remember it was working fine before I re-installed windows but now don’t know what happened. Though it goes to stand by or Hibernate but the system wont wake up unless and until I press the power button to restart. It takes over minute to enter standby and pressing keyboard keys or moving mouse don’t affect once it is gone.
As per troubleshooting I updated BIOS, updated Video Drivers and also checked all proper options in Power management by nothing seems to be working. Any help would be appreciated.
