Plugged in, not charging and shuts down instantly on removing adapter

[dikshant_25]

My laptop is 2 years old and is not used much. I updated the laptop whenever it said update and shutdown in windows icon. It was not used for 15 days recently and after I started using it again, now I cant use it without the adapter. It shuts down instantly on removing the adapter. It says plugged in and not charging when I use it.

There is a 45 and a 65 watt charger

Possibly with a nearly dead battery, the 45 watt supply can not both charge and run the notebook at the same time.

Turn the notebook off and let it charge several  hours then do a battery report

Please run the battery report and post  the summery
you run the battery report by bringing up the administrator command windows "cmd" and running powercfg/batteryreport as shown below

After entering that explorer line you should see something like the following. You will have to click on it as it is long

Look through the report for anything unusual.

Possibly 2 year old battery that is 3 cell has run out of life.  Just guessing.
