I have a Dell N5010 that i'm working on for a family member, they spilled milk on it and fried it. I replaced the power board due to white residue covering parts of it, it didn't work. Then I noticed some white residue on the motherboard and replaced it, it didn't work. So then I replaced the processor, it didn't work. I replaced the power supply, and the ram and have all the parts connected outside of the case sitting on my desk and the most it will do when I plug it in is the LED for the front panel flicks on then off and nothing happens. I'm very confused.
