Laptop plugged in, not charging

Laptop plugged in, but not charging:

This was a really annoying issue, since I had bought the laptop just 3 months back.

I searched in HP forums, (mine is a HP laptop), there were a range of suggestions

1) Uninstall Battery adapter from Device manager

2) Restart !!

3) Re-install the power manager software

4) Replace the battery

5) Contact the manufacturer

Mine has AMD processor, but the laptop was very hot; something very unusual.

Silly reason: the laptop was placed on a soft couch; there was absolutely no ventilation.

I don’t see a connection between ventilation to battery charging; Anyway, the below worked.

Solution: Lifted the laptop so that the air vents on the bottom, sides are not blocked. It started charging !!
