Question about HP Pavilion a620n (PC028A) PC Desktop
When I turn my computer on, the monitor shows the Dell logo and then goes into sleep mode. I cannot change any settings or adjust anything since the monitor goes blank almost immediately. My monitor keeps going into sleep mode. Also when it flicks back on I get millions of little blinking pixels. I thought at first it was just the monitor but I've switched monitors, no change. What is causing this and how can I fix it?
This is normaly cause by incorrect power management settings.
check power management setting in both windows and your computers bios
you will not need to worry about the power management settings of the bios when an operating system such as windows is loaded.
