I am afraid there is no method to check which component is bad in the motherboard; once the motherboard is failed you need to replace the complete motherboard.
Sorry for being late at this, was held up at work !
Another thing I came across is that when I keep the charger plugged in, the time and date doesn't reset and it doesn't turn on by itself after shutdown. It just do so when ever I take off the plug and plug it in again.
Also if it helps, my battery is also dead , been using is through ac for a long time.
Does it still sound like I have to change the motherboard? or can it be solved?
Since you have changed the CMOS battery and system is still not powering on, you can release excess flea power and check the system is working. Please follow the steps below.
Switch off the system; remove the battery, ac adapter and the power cable. Press and hold down the power button for thirty seconds to drain any excess flea power. After doing the above steps still the system is not powering on then the motherboard is faulty.
The thing is after changing the cmos battery my notebook ia still not storing the fate and time and Its showing the failure messageagain. And with that whenever i Plugin the Charger cablein thelaptop it starts automatically.
But this doesnt happens when the charger remains plugged in even after it is shutdown.
But when I take off the charger after shutting down and plug it back in the laptop turns on automatically and the cmos fails again.
Take a close look at the battery holder itself(!) and make sure that the battery is properly inserted and making good connection.Sounds stupid I know,but I have a calculator here on my desk that almost drives me crazy because every now and then I have to reseat the battery even though everything looks nice and shiny.....
=================
The reason why the system works if you don't take off the charger could be the fact that the charger powers the BIOS/RealTime Clock.This is common practice in electronic systems where it is necessary to keep a backup battery alive as long as possible.Not sure if this also applies to laptops,but I am always looking for explanations.....
=================
If you haven't tried it yet : reset the BIOS to its "Default" values (F2 at power up to enter the BIOS)
It’s good to know that you have load defaults in the BIOS page, also please let us know the progress once you reseat the CMOS battery properly in the system.

Unfortunately, it sounds like you damaged the mainboard - it will need to be replaced.

I think you've got it all wrong.
The thing is after changing the cmos battery my notebook ia still not storing the fate and time and Its showing the failure messageagain. And with that whenever i Plugin the Charger cablein thelaptop it starts automatically.
But this doesnt happens when the charger remains plugged in even after it is shutdown.
