Hello. We have an Asus Transformer 101. It keeps shutting down every night I put it on charge. It was ok for a few weeks after we bought it. It never shut down by itself. This problem is recent - just almost a week old. During a daytime it's running fairly ok, before going to bed we put it on charge and every morning we find it shut down and it takes us quite a while to start it again. Any advice or suggestion, what it can cause? Thank you in advance.
