What's the full ACER  model number? Jack E/NJ

OK. Let's try to do a battery re-set like Sharangi suggested above. On the bottom, there's a pinhole as in the image below. Get a paper clip and insert it for 4-5 seconds. Then try it out again. Jack E/NJ

 

I'm guessing the charger is the problem. Does it have a dual voltage switch? Make sure it's set to whatever your mains are in Cinderford. I assume 230v. Jack E/NJ

Does the charger's plug have a hole in the middle? If yes, check inside the laptop jack to make sure the center pin is straight and not bent off to the side. Jack E/NJ
