Hi, But how can i make sure ? Actually whenever i lock and leave my m/c ideal for sometime the screen becomes blank. This verifies that APM deamon is running. But the problem occurs while i am working... even while i am typing something... Can it be the case that even when the m/c remains ideal momentarily APM switches it off. But then why does it comes back own its own without any intervension ? Moreover if i do not lock my m/c and leave it ideal then the display is still there i.e. it does not becomes blank. What else i can check for - Vikram hi Are u sure it isn't a power management problem . Check out the BIOS settings or the APM cheers cheedu > > > Hi List, > > I am using RedHat 6.1 (PCQ CD), and using P II with 64 MB RAM, 8MB > > I am facing a strange problem with COMPAQ V75 monitor that i have.
