why is my computer not charging when plugged in


Blow on it! I had this problem. Did lots of internet research, then replaced the AC adapter. This solved the problem for a couple of months, but the other day I started getting the same message again. After checking all of the connections and making sure the battery was properly seated, I still couldn\’t get the system to charge. Back to the internet to see if anyone had any other clever tricks to get things working again. I was about to pull the machine apart and re-solder the power connector tot he motheboard when I ran across the silly advice to \”blow on it. \” They said to blow into the tip of the little round plug, and into the port on the side of the laptop.

What a ridiculous idea, but it was easy and free so I figured, what\’s the harm. I tilted the laptop up on its edge so the power port was close to my mouth, pulled out the plug and gave a couple of quick blows into the tip of the plug and a couple more into the port, then plugged it back in. Viola! It actually worked! I don\’t know if it was a matter of a little dust or lint in the connector or maybe the moisture in my breath helped establish a better connection or if I have magical super-powers that I didn\’t know about. All I know is that it worked. A couple of days later, I had to use the computer on battery power and when I plugged it back in, again \”Plugged in, not charging. \” I pulled the plug out and put it back several times, but no help, just more failure messages.

Again, I blew into the tip of the plug and into the port, and again, the system responded by showing the battery charging. When I have more time, I plan to experiment with my old Dell adapter, and try using some good contact cleaner on the plug and port, but for the moment, Blowing into the plug and port seem to have solved the problem. Try it. It worked for me.
