Acer aspire 5 laptop of model A515-51g has its power led blinking in orange and the laptop powers off when supply is cut. I have referred to other forums and tried things saying take out battery for ten secs or hold power button for 15 secs then plug in battery. But my laptop has an inbuilt battery so I had to tear down my laptop to try it only to fail. Is this related to BIOS? And sometimes when i move the laptop like lift it in some awkward angle, it powers off. How to solve this?
