My Acer Aspire 3 A315-55G-549B is not turning on. May be my motherboard is damaged. How can I repair it . And what's the coast
[Edited the thread to add issue detail]
The main problem imo is that your laptops power rail has a shorted mosfet at its initial power rail that has shorted the laptop power and is the reason for this problem. I suggest that you take the laptop to an experience technician that can analyze and pinpoint the fault exactly and fix your laptop. Check the battery also if you haven’t changed the battery since new, but that is only a minor issue and your laptop should power on. Good luck and hope this helps you out.
The red circled area is where the main power rail has to be diagnosed and the shorted mosfet that has blown needs to be discovered and changed, so that the power rail works again, which is a specialist job that you can't do, so take your laptop to an experienced technician.
Or have a look on eBay as there is a mobo for sale that you can change and fit for fraction of the cost of a technician doing this job. Here is the GENUINE ACER A315-55KG MAINBOARD for US $59.88.
