Hi,
 

The laptop screen started flickering when power and battery was in, fumes then started to come from the laptop when I disconnected the power cable and re-connected it.
 
The laptop works fine using only the battery but when connected to 2 different power cables, fumes start to emit from it but it doesnt overheat.
 
Could this be an internal problem or battery problem?
 
Thanks

Please explain the two different power cables.  

 

Are you using the proper power adapter and cable?

It isn't clear from this part of your post which 'It' you are referring to - the laptop or the battery ?

 

In general, fumes of any sort coming from electrical / electronic equipment is a bad thing and not to be encouraged !

 

There are two components involved here - one, the voltage / current regulator circuitry on the motherboard where the power lead plugs in, and the other is the battery itself. The voltage / current regulating components can fail, and smoke in the process, but they will not usually do this for long. Batteries can fail in strange ways and emit fumes in the process, but they usually get hot, or at least warm, while doing so.

 

As you say this only happens when you have the battery connected through the charger to the mains, I would suspect a failure of the regulating circuitry which is allowing over-voltage to the battery. I would suggest you take the base plate of the laptop and have a look at the motherboard for any signs of charring or burnt / blackened components. If there are any, you are looking at a new mobo at least.

Like Chris said, you will want to check for any black spots, If you cant find any then I would suggest investing in a new battery and or a new charger. Most likely the charger would not be the issue due to the fact that you have two. Over voltage may be an issue with your motherboard or simply an issue with one of the chargers. 

Hope this helped and good luck to you! :)
