I have an Acer laptop (mentioned in the title)... Today it suddenly turned off without any previous sign of some problem ( I was just browsing) it was connected to a charger so I tought that the electricity went off but no. From that moment it wont start from battery or from the charger...none of the lights come on what can tell that is actually connected or charging or whatever... The only think is there is a silent click noise from the laptop.. Approx. one click per sec. Any ideas what can be the problem? Thank you in advance.
