Question about Acer Aspire 4520-5582 Notebook
You First need to test your AC Adapter Cord...
You can test if you have a secondary known working one.. plug that one in to see if same issue occurs.. OR you will need to test the AC Adapter using a multimeter (available at any home improvement store for under $7).. When testing the Plug End on the AC Adapter - Hold The Negative Test Prod Of the Multimeter to the Outer Side Of the Plug Tip, and Put The Positive(red) Test Prod Inside The Plug Tip... See If You Have Power Through The AC Adapter Tip... You Might Need To Slightly Wiggle The Cord Near The Tip End To See If THere Is A Short In The Cord....
If Cord Tests Good....
You Will Need To Replace The Laptops DC Jack...
The DC Jack is the port where your AC Adapter Plugs into on the laptop..
Your Faulty DC Jack Would Need to be desoldered, the motherboard cleaned of all old flux, Re-Tin The Contact Pads and then Resolder a New DC Jack Onto The Motherboard...
