Sony Vaio Laptop Plug Overheating

Tennisjon2002 462 36 October 11, 2010 at 08:53 AM
My girlfriends Sony Vaio has a plug that is heating up way to hot. She says when it is charging it will get hot enough to burn her and even said it has started a burning smell. It is burning hot on the tip of the plug that connects to the computer and the area on the laptop is too hot too. I was thinking maybe it needs a new power jack? Any ideas?

Ya that sounds bad. I would look inside to make sure there is nothing stuck in it on either the computer or laptop. If its under warranty call Sony ASAP. If not I would not use it till you get a replacement.

OP, even if it is out of warranty, Sony has had recalls on Vaio laptop Power Adapters -- contact Sony Tech Support and see if GF's laptop is affected.

I do not believe it is affected by any recalls. It is model vgn-fs715w

Also just found out she has 2 charging cords and both of them do that..... which leads me to believe it is not something with the cord.

Sounds defective. Leave it plugged in until it melts or catches on fire, take pix & call Sony support. They'll probably agree to replace it if you ship it back to them. ;-)

No, it could mean the problem is in the computer instead of the cord. Most likely in the port itself. Getting warm is normal but it should not get hot. Call Sony they take these things seriously.

That is what I was implying, not the cord, it must be something with the computer. I will give sony a call.

you're sure that it's not one of the laptops under recall either for power adapter or battery pack? I know someone whose house burnt down because of one of those, so I wouldn't mess around. Either send it in for the $40 or take it to your local comp shop. Small price to pay compared with the hassle of a house fire.

Other thought -- check to make sure it's not one of the Vaios that's under the NVidia GPU recall. That bad chip can cause the comp to get extremely hot as well and the vent may be near the power cord plug, which could lead to confusion about the heat source.

That's a good thought. Ask her if it gets hot only while charging, or also unplugged and running on battery.

I think she needs to take it somewhere. This isn't going to get any better and could become disastrous.

sounds like the battery might be failing - the charger is trying to over compensate.

So I figured out the laptop is heating up even when not plugged in... and stays cool when the laptop is plugged in but not on. So I think it is just the laptop heating up for some reason. I gave my gf my laptop cooler and that seems to really help, the laptop stays cool. I think I am going to try to take the laptop apart some and spray with compressed air etc. And the laptop is not under the NVidia GPU recall.
Anyone know where to find a teardown guide?

You should be able to find a guide via google. OOC, does the Vaio have the NVidia GPU? My wife and I both have computers that are affected but aren't part of the recall. Feel free to check out how I feel about that in the appropriate thread, but moral of the story is that just because it's not part of the recall doesn't mean it doesn't have a bum GPU. To see the GPU, go to Control Panel -> System and Security -> device manager and look at display adapters.
