Hello guys,

since May 2015 I have this Notebook and never a problem. Just a month ago I started having problems with the battery (flashing orange battery light). I replaced the battery but every time I connect the notebook to any docking station or even to a port replicator, the battery light flashes orange and white. The PC starts up anyway but it's as if it's slowed down. It takes a long time to start Windows. At the moment the only way to make it work normally is not to use the docking, connected to the electrical outlet via its power supply. The battery indicator does not indicate any anomaly. However, I still noticed a small problem.

If I connect the power supply connector to the notebook, without connecting it to the electrical outlet, the connector LED lights up blue as if there was a voltage return from the battery towards the connector. It didn't happen before.

What could be the problem in your opinion? How can I solve?

Thanks in advance to everybody.
