It indicates that something is accessing your hard drive(s). This could be the operating system, applications you are running, your wi-fi connection doing some hand-shaking, or even malware.


It normally flickers fairly regularly if you are not doing very much, but if you are concerned, download a copy of Malwarebytes from here :


Malwarebytes Anti-Malware


install it, follow the on screen instructions, run a quick scan and see what it says. Should it show up any problems you can't solve yourself, post back here in the 'Am I infected' section of the site.

I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !

It's not an "activity" light as such, it's a hard disc light and it shows your hard drive is being accessed. Could be anything from indexing to an app scheduled to run when the system is otherwise idle (defrag, av scan, etc). You'll need to provide more information if this doesn't answer your question.
