Lusty Posted September 8, 2011 Report Share Posted September 8, 2011 Hello chaps. I have an Acer Aspire 4535. Sometimes after using the head phones,I remove the jack from the side and there is a red laser shining out of the hole and all the time it's on,the built in external speakers don't work. After awhile it turns it's self off however. I assume it's supposed to be there so my question is:What is it?What activates it and how do I turn it off myself?
