Whenever i am pressing the power button of my laptop its not getting started in the first attempt or not starting at all but when the battery is disconnected and adapter is connected after draining the flea power its getting started in the first attempt similarly when both the battery and adapter are connected its powering on without any issues so what could be the problem and also after powering on if i shut it down and then again within a minute i start it by pressing the power button it works without any problem so please suggest remedial measures.Model is Dell inspiron N5050 purchased last year.
