I'm not sure if this is a new problem or not as side of monitor was not visible before - I just moved the pc to a new location so now I can see it. Anyway, it is a blinking light that sits right above the on/off button. I am not sure what the icon that accompanies the blinking light. it is in the same location. The icon looks like a "can" - maybe it is something related to disk drive.Thanks for any thoughts.
RE: Blinking light on side of monitor - Inspiron One.
The blinking light that looks like a "can"is the hardrive activity light.
A hard drive activity light is a small LED light that illuminates whenever the hard drive or other built-in storage is being read from or written to.
Knowing when your computer's hard drive is being accessed is helpful so you can avoid pulling the battery or unplugging the computer while the operating system is still accessing files on the drive, a mistake that can cause corruption of important files.
A hard drive activity light is sometimes referred to as an HDD LED, a hard drive light,or a hard drive activity indicator.
