Shan, before replacing anything, the very first thing you want to do is to remove all power from the computer, that includes the battery. After that, disassemble your computer right down to the motherboard. Follow [guide|3779|this guide.] Then clean '''all''' the parts with isopropyl alcohol. Use the highest grade, preferably 90% or better. You local pharmacist might help you with that. The "visible signs of dried white water marks around components" might already by corrosion. Once it is absolutely clean, visual inspect it. Look for burned, charred, or missing components. Take you time with it and look careful. It does have a lot of SMD components and requires a sharp eye ;-) Find the component PF1 which is a 5A fuse and PD5 which is a special diode, called a voltage supressor, replacement part is number is P4SMAJ20A SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR POWER - Pan Jit International Inc.. Make sure that those are okay. You may need a multimeter to check on those. Hope this helps, good luck
