    Hello I have a hp pavilion dv6. my laptop power supply from the charger stopped working recently I opened up my laptop to get a look and noticed one of the little black squares on the motherboard/chip (not sure what it’s called) shorted out aka burnt out and sparked whenever I plugged in my laptop charger and looks burnt out. which I’m guessing is the problem of why my laptop charger isn’t charging my laptop. I may have split some soft drink on my keyboard and it sunk through to short out that chip not sure. The number next to the little black chip that sparks is PU4101 not sure what that number is referring to or how to find out what that means and if that is even the problem that is causing my laptop to not charge. Is there any way to fix this chip even if it’s a home fix thats not exactly professional that would get the laptop charging again? or is there shortcut to be able to charge the laptop again as i really need it running? Or would it require to replace the whole motherboard or just the chip alone?. Aka is it even worth fixing? or just replace the laptop now? Thankyou for your advice much appreciated.

    It would need to be removed and replaced. As it's on the motherboard, it's not likely a simple task.

    Also, just because you found a fault, doesn't mean that it's the only fault. It could simply be the weakest link. There could be another fault or the charger itself could be faulty thus effecting the chip that you found.

    If it's under warranty, have it serviced (in which case, they will likely replace the motherboard or the entire laptop). Otherwise, it's most likely more cost effective to simply replace.
