When I connect my laptop for charging using the power adapter, it starts charging and after few minutes it stops. .....
Sorry, my specialty is electronics, this is a reason why I have such a question.
How do you know that charging begins and then stops? Have you measured it in some way?
Let me elaborate what I have observed, when the battery level has reached some level it gives me a message saying to connect to an adapter for charging, and when I connect it, laptop starts charging, the battery symbol now shows a plug beside it indicating charging and a red light glows near the plug connected to the laptop stating the same. Now after few minutes, plug symbol and the light goes off which means the laptop is not charging, even there is no disconnection of the supply.
I did some voltage measurement of the adapter to check if it is working properly. I first measured its voltage without connecting it to the laptop which measured around 19V and then connected to the laptop, And when the light goes off, I removed it and measured the voltage which was nothing. I then thought it could be an adapter issue. But I then realised that let us do an another scenario, this time I measured the voltage of the adapter at the initial stage after connecting to the socket and after few minutes probably around after 10 minutes, the voltage remains. Now the first case might be wrong due to this experiment.
This is all I did.
Your Suggestions are welcome.
What percentage is the battery? HP laptops will normally change to 100% and then stop charging until the battery drops below 95%.
It stops at any battery level.
