What To do if my motherboard is fried?

Hi, recently I accidentally spilled some water on my laptop well I did immediately took the battery out and tried to dry it . Problems here after drying it with hair dryer I tried to power it on , so to try it better I shut it down and power it up again it is still ok but mouse is completely invisible and unusable. Third time blank nothing came up . Took it to the place I bought my laptop lay there for a few days hoping for solution but they said the motherboard was fried but did not say which components. Other than changing the motherboard which cost about a new laptop what should I do to save it . Will reflowing it help ? If not what to do ?

Hi, thank you very much for your reply. Now, after sometime my laptop seems to be perfectly fine and working. Now I have a new problem. All usb ports are not working , software checked all working properly but the hardware part was that my usb port are all not functional thought. I am not greedy as after all my computer powered up everything here are good but my usb ports are blank just to ask how much will it be to replace my usb ports ?

Tam Alden, it may not be your ports but your circuitry. You will have to clean your board or you will get more damage as time progresses.

Tam Alden, your options are really limited here. Instead of using a hairdryer to try to dry it out, you should have disassembled it and cleaned it properly. that means isopropyl alcohol and a brush to get rid of all the contaminants. The continuous turning on most likely shorted out multiple components on the board. So, unless you experience in trying to find out where the short is and the to source the new components and microsoldering, there is not a whole lot you can do. At least you could try and find some obvious damage by removing the board and cleaning it.
