ASUS X555LA, 20 months old, Windows 10. Used about 8-10 hours a day, plugged in. Once a week used from batter until drained, about 2-3 hours. So about 80-100 battery cycles.
Starting yesterday, plugged in, doing my thing. Screen suddenly dims. It's plugged in but not charging. Swap outlets, same thing. Check connections and materials, everything looks normal, no wear or damage.
Try different outlets, same thing. Flip adapter over, that seems to fix it... for a few hours. Today, plugged in, not charging. Battery draining (21% now).
Please help! I'm reasonably handy, but I don't have money for repairs. And it isn't like the battery is worn out, it has been giving the same 2-3 hours performance on battery since forever, and did so recently.
