Laptop hp pavilion g6 2016 tx not charging or booting

Question

My  laptop is hp pavilion g6 2016tx ( Intel i 5 with 1GB AMD graphics 4 GB RAM, 500GB HDD 15'' screen ) which is around 2 years old and now out of warranty.  I had a strange problem with it. I used it till last Sunday ( 24/08/2014) and after use I properly shut it down and kept in my laptop bag. On Monday evening when I was switching on it was not  booting. I plugged in the charger and then noticed that it was not charing and no LED light for charging. I did hard reset ( by pressing the power on button mor than 30 sec by removing battery and charger and then trying to power on) but system not booted nor charging. I checked output voltage of charger and it was OK, battery is also fine.
I took my system to authorised hp service centre on 28/08/2014, and in front of me they tried to switch it on and then told that there can be motherborad problem, and they will diagnose and tell me next day what is the exact problem.
Next day, 29/08/2014 evening they told me that some liquid spill is there on keyboard and NOT A SINGLE KEY is working. I told them that there is no chance of liquid spill as I am the only one using the laptop and until last shut down on Sunday ( 24/08/2014) laptop worked very well and all keys were OK.
Then they told that they tried to boot with a different motherboard and got error screen (blue) while booting, and  toldme that I have not shut down my system properly last time and even if they replace motherboard I may have a corrupt OS. They also told that they don't have spare Processor for checking my laptop (intel i 5 CPU) and have to order for new one. I asked them whether processor is faulty, then they said nothing.
I am a graduate in Electronics and Post Graduate in Computer Applications, and for past 20 years working in IT dept of a Bank and have experience in harware trouble shooting as well as on Software.
I told the service center people that I cannot believe that there is any liquid spill on key board and NONE of MY KEYS are working, because until my last use and shutdown on Sunday, system was working fine and no one else touches it other than me. I told them that when you replace motherboard, OS may give blue screen because of HW compatibility, but they are telling me that I did not shut down my system properly.
They are telling all unbelievable nonsense (as telling to a layman who doesn't know anything) to me which cannot be digested by me.
I feel my system can have some shorted component at power supply area on mother board or maximum a faulty mother board. But the service center people are trying to tell that my keyboard, motherborad , cpu as well as graphics card etc..( list can grow since they have not given me quotation as promised on 29/08/2014).
I doubt some foul play by the service center and they are trying to cheat me by removing good components and making me pay more than half of my laptop purchase price ( Rs. 46500/-) .
I have made some markings on my motherborad , battery , HDD and RAM to identify it in case some one changes it. But how will I know if they are removing my good Processor, as well as graphics card or even mother board which may have component failure at power area which is serviceable.( Like MOSFET, Capacitor etc).
How I can get the serial nos of all components of my laptop or identify if someone replaces it.
What could be the booting/charging problem . since my system worked fine until last shutdown.
I request help and suggestions on this, like what to do if the service centre cheats me.  Please Help!

Thank you for the reply. I am waiting for the quotation from hp. Sure I will contact hp directly. But the call centre support in these kinds of tech issues are of no use, at least from my experience. I did talk to the head of service dept (at service centre), and he told me that they don't have spare board or processor and have to order to hp once I accept quotation, but I can choose to go for replacement of any faulty components, once they receive the items from hp or  I can opt for just walk away from them without service by just paying their service charge of Rs. 850/-. In that case I have to find out some reliable fellow who does chip level service ( if at all possible.)
