Hi guys i need help. i installed windows xp pro service pack 2 via bootcamp and the installation was successful. Its running fine and pretty fast but there is one problem. When i shut down the lid i think it goes to sleep mode or not. And then when i reopen it the screen flickers on and on and on forever well i only waited for 30 seconds and got tired of the flickering so i just restarted. i dont know if it stops after a minute. but anyways do any of you know how to fix this issue.
