  HP laptop power plug getting HOT!

HP pavillion dv8327cl notebook, warning message says battery needs to be replaced. Is a weak battery cause for the plug that goes into the power jack to get very hot? Also, the battery indicator will change from charging to battery power while in use. Sometimes wiggling the plug will restore charging, but more often than not, the plug must be removed and reinserted to take the laptop off battery power. When that happens, the charging indicator comes on, and the plug gets very hot again.

What are the model and specifications (volts/amps) of your power plug?

Huh? I'm talking about the plug on the end of the power cord, that plugs into the socket on the side of the laptop.

Yes I know. But if you are using an incorrect adapter or a generic one, this is the sort of thing that happens.

You likely have a switching power supply. It's going to be hot when power is being drawn to charge the battery. If your battery held a charge, the power supply would switch off and cool down.

The power supply is cool. It's the plug that gets hot. It got hot enough to melt the insulation off the wires and it shorted out. I took the plug apart, stripped the wires and resoldered it all back together. Now there is no covering on the plug and while charging, the metal part gets so hot it blistered my finger. Once the battery is fully charged the plug cools off. I know the battery is weak and I'm just wondering if that is what is causing the plug to heat up like that. Would a new battery cure the problem, or is something else wrong. I don't care to put out the money for a new battery if there are other issues with the laptop.

My laptop is just over a year old and I've recently begun to notice how hot my power cord charger is getting - if my foot touches it I feel like I got burned. This just doesn't seem right. Is there a recall or service notice from HP or the cord maker on this? Will simply getting a new cord fix the problem?

Give HP a call and tell them that many people are reporting this same problem. It's possible they may have a solution, or at least offer a replacement.

It's not unusual for a laptop's AC Adapter box and the plug on the laptop side to heat up during battery charging. The ones on my work laptop (Dell Latitude) heats up crazy too, like 80C. But if your plug's insulation is starting to melt, then you have a problem! Something's not right. Like mentioned above, go get proper replacement of battery and AC adapter units. Or perhaps there's a short on the laptop's power port, check that out and get it repaired.

I know it's not the case here, but if it's the plug on the wall outlet side that heats up, unplug it immediately, you may have a short on your outlet.
