@ajeeaspt okay, let's stop looking for any specific IC. Forget anything about this IC for now since there are a few dozen of those on your motherboard. Reading your explanation, you have a water damaged motherboard/computer. The very first thing you want to do right now is to STOP! STOP using it, charging it, trying to turn it on etc. All this does is make a bad situation worse. Unplug it from the AC supply.
Next step for you to do is to disassemble your computer. Download the Service Manual for it from here
Remove the motherboard the I/O board etc. Take a careful, close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. You will have to remove all the EMI shields, the heatsinks/fan etc. If there is any gross contamination to be cleaned, do not use drinking water, if you need to use water, use sterile water. Once you got that gross contamination cleaned, use 90%+ (at minimum, higher if you can get it) isopropyl alcohol and clean all of your boards some more.
For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your laptop as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. Also, you do not need to leave it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning.
It would of course be best to get it professionally cleaned with an ultrasonic cleaner. Once your boards are cleaned, take some large, clear pictures of those and post them with your QUESTION. That will allow us to see what you see. Everything will be a guess until you have taken care of the water damage. Once it is cleaned properly, reassemble your laptop and re-evaluate. you will need a new battery to ensure that you have a known-well starting point.
WE need to see your boards so we can try and help you find a schematic to hopefully help you to fix your laptop. It is not going to be "quick and easy" but it is probably doable. So you need to be involved with this repair. By that I mean following the advice of the great people/community on here. We are here to help you, but you have to do the work.
If for whatever reason you can't do this, or if you feel this task is to daunting, I suggest that at minimum you replace the motherboard, the IO board and the battery.

Did we come in right in the middle of the movie? Because we have no idea what you're talking about: What IC are you talking about? You'll have to elaborate or there's a zero percent chance you're going to get any help.

@dadibrokeit that repair man told IC was damaged i am not a computer guy i know know what exactly irlt means but i think it was internal circuit (IC)

@dadibrokeit it think this is what I was trying to say https://www.laptopparts.in//ic-and-compo...

@ajeeaspt "I.C." is an abbreviation for Integrated Circuit, which generally means any chip that incorporates multiple transistors in a single package. You laptop probably has at least 40 or 50 ICs on the circuit board and more scattered around the display, I/O ports, LED indicators and other parts.
So unless we know exactly which IC the repairman is referring to, we can't even guess what to tell you.
What is your computer doing that made you take it to the repair shop?

@dadibrokeit this is whole lore
One day while working water fell on keyboard around 10 ml i quickly power off laptop keep in keep it in up side down position so water would be at screen instead of going further inside i quickly got home it took around 1-2 hr i power off then opened it i was glad since only keyboard was wet other components were dry i clean the keyboard and connect all components again i tried to power on but it didn't i ignored and reassembed it then try to turn on it turned on after few tries with charging on but my laptop was very laggy some time display flicker(on and off very few seconds)but it was not over heating one thing that supriised was the icon of battery in laptop was not there it was of a cable ion i thought battery is not working so laptop is on power supply from charger
During all this process the indicator light was flickering in red and white again and again (red =low battery white=charging)
