Laptop Plugged in Not Charging (HP, Dell, Lenovo)

I recently bought a HP Pavilion dm3 laptop, nice looking ultra portable laptop with low power Core i3 CPU. Everything seem to be working fine till I noticed that the laptop battery won’t charge when I plug it in. It would just say Laptop Plugged in, Not Charging. It gave me the real scare, after all it was a brand new laptop and for a moment I felt that I would have to send it back for repair. But as usual I googled for this issue and it turns out that most modern laptops (Dell, HP, and Lenovo) are equipped with this new feature to prevent battery over charging.

So unless your battery level goes below 90% mark the battery charging won’t start. So I let my laptop battery go below 90% and then plugged in the charger and it worked, charging started normally and it went on till it was fully charged.

I had similar problem on my old Dell Inspiron E1505 also, and in that case it was a faulty charger, it would power up the laptop but it won’t charge, even if the battery was drained to 10% or so.

Bottom line, if your laptop tell you “Laptop Plugged in, Not Charging” then it has to be one of the two issues mentioned above.
