I have a dell inspiron 1525, after about 60 seconds the screen goes black. The laptop keeps on running but I have to close the lid and reopen the lid and it stays for another 60 seconds and I have to perform this over and over agian. The power setting are set to never shut down and the setting for screen save is set to 200 minutes. This is running windows XP service pack 3 and all the drivers for the 1525 are loaded. Does any one know what the possible problem may be. Also hiberation is not on.
