I have a Dell N5040 laptop. It was connected to a shorted Power Supply and you could smell smoke. I opened it up and found a burnt chip which leads to the center identification pin from the PSU. I cleaned it but that didn't do the trick. I'm wondering if this chip is replaceable or even purchasable. I've soldered laptop power jacks before so I have the tools.
The computer gives a warning saying it's not a genuine charger and may not charge the computer. I've tried a new genuine dell adapter and same story so I'm pretty sure it's the burnt out identification chip. Pictures are linked below.
Any help is much appreciated.
