I just received a Razer blade 2014 laptop 2nd hand from the us and its apparent that the battery has a problem. It needs the charger to turn on and when i open it, it says 100% charging in the icon tray but it the has an x over the battery icon once every now and then. its running windows 10 and after unplugging the charger it turns off instantly. Is the battery simply dead or is there a fix, sending it back to the US Razer store isn't an option and im waiting for a reply from the eBay seller about this. Does anyone know of any high capacity external laptop power banks available to remedy this situation?
