Burning smell on my laptop

I smelled a burning smell recently while using my laptop. When I unplugged the ac adapter, the plug that plugs directly into the back of the computer was extremely hot. I unplugged it and used my battery for a bit. When I plugged it back in, the computer would not recognize that the AC adapter was plugging in and it still ran off the battery. I bought a replacement AC adapter thinking that was the problem. The battery was almost dead but not completely I think. Anyway, when I plug in the new AC adapter, nothing happens and now the computer won't even run off the battery. The burning smell returns when I've plugged in the new AC adapter.

The warranty is up but I still need to use the computer and it's still good other than that.

What else can I do?

    I took the notebook apart and I can see the DC Jack has 5 spots where it's soldered to the main board. The fifth (center) spot has melted through the original soldering and left a brown burned mark on the green board around it.

    I don't know if this was the correct thing to do, but I soldered the center wire back to the board. I then plugged it in w/ the notebook still taken apart so I can see better, and it sparked at that center spot. I quickly unplugged it and added a little more solder to it, thinking I may not have made quite a good enough connection. I plugged it in again and it didn't spark, but this time smoke came from the DC jack.

    I'm going to try and buy a new DC jack from Asus on Monday and replace it myself.

Unless you have the ability to to replace the plug connector part yourself, you will have to take it in to a shop who can do that kind of fine soldering for you. If nothing else is damaged, it should be ok with replacing just that burnt out part.

Burning plastic smell coming outside unit

It probably wasn't soldered correctly, it happens, you should turn your computer off and unplug the PSU so you dont fry the CPU, then try resoldering it or take it somewhere to get it done. it also might be the wrong replacement part, too loose..

Laptop charger smells

Laptops (esp. older ones) should never be left plugged in 24/7. You need to stop using the charger (the problem is only in the charger and NOT the laptop?) and replace it. The burning smell is something overheating which can lead to a fire and sparks are rarely a good sign.

I'd cut the cord on the charger, so it can't be used again and replace it.

If you have a burning smell I would not plug it in again it may could cause a fire. I would take it in for service and have it checked out.

About little bit of smell coming from my laptop

What I have seen in my business is this: With laptops the power cord adapter places too much strain on the power connector and weakens the connector or the power cord that plugs into the laptop has taken a hit and it breaks loose the power connector from the motherboard. This is a serious issue as further use will destroy your motherboard from electrical arcing. Once the mobo becomes burned out in that location you will need a new motherboard. If you can find someone to repair the laptop then I would have them look at it. Laptop repair is not something for amatuers with no experience with electronics repair. Laptop repair can be accomplished with patience and experience. Anytime you smell something burning and hear crackling it is not normal.
I would start with looking at your adapter end that plugs into the laptop, if this is damaged you can try to get another adapter. If it looks OK then I would have a technician look at your laptop. Continued use like this will cause further damage.

Notebook smells like burning plastic.

cud be your onboard voltage regulator for the battery charging. if you remove the battery and use the external power source does it smell also?
if the battery charges normal out of the unit, and the laptop works well with the AC power unit without the battery, then it's your voltage regulator for the batt charging

Notebook smells like burning plastic.

If the new Targus charger is really rated correctly for your laptop, your battery isn?t charging and you smell the burning plastic coming from the laptop when you plug it in that is a fairly dangerous situation and you shouldn?t plug it back in anymore. The power from the charger runs through a PCB board which distributes power to other components in your laptop. I suspect one of the components (probably a capacitor) had a catastrophic failure and is the cause of the smell and the lack of battery charging. Once again assuming that the Targus is the correct one for your laptop current you probably have a laptop damaged beyond home or economical repair.
