Hello

I hope that I posted this in the right topic.
I tried to build a simple V- meter with my arduino. I built a voltage devider with two capacitors ewerything worked fine untill by accident I turned the phase and zero pins around and sent 230V directy to the GND pin of my arduino. Obviously I burned the arduino and also ALL my usb ports stopped working. I have an asus K53sv computer.
My question is if there is any possibility of replacing anything on the motherboard or do I need to buy a new motherboard.
 
Sorry to say, you are most likely looking at a new laptop.

The K53sv is probably going on 5 years now, and even if you found an exact replacement board (ebay is probably one of the best bets), I'd bet it be easier to just buy a new machine than go through the hassle of tearing apart that machine.

Just from a safety standpoint, I wouldn't trust that my house wouldn't catch on fire if I tried to fix that now.

Nothing is impossible with the right skills and tools to do the job, but I would not risk using an electronic component thats been fried in my house.

Maybe I'm wrong, and I obviously don't know your qualifications, but seems to me a lesson has been learned here and whether its today, tomorrow, or next week - I'd be replacing that laptop and not mess around with the new one unless you know what your doing.
 
Most USB functionality is integrated into the southbridge of the board, which would be extremely difficult to replace yourself and take more cost in parts and labor to attempt than just buying a new laptop.

That being said there are plenty of expresscard to USB modules that you could consider for add on USB connectivity.
