As I mentioned before, SOME computers will not start.  I cannot be sure 
yours is that way.  Just a word of caution.

The AC power really powers the circuit AFTER the CMOS is read.  Many 
computers look for the reading from the CMOS to be powered by the 
battery and THEN allow the AC power to start.  Since most use a coin 
type battery (CR2032) and they cost only a couple dollars, it is a cheap 
way to eliminate this as the cause.

  Also, how do you remove its battery? It is like
> stuck.

I am not familiar with this particular computer, but my computer has a 
holder that contains the battery and from the terminals of the battery 
powers the MB via a two pin wired connector.  If you have this type of 
setup, then the battery may be replaced the holder.  If not, you might 
need to buy the assembly rather than replace the coin battery.  They are 
not hard to find at a Radio Shack or Best Buy.

Do you have a voltmeter so you could measure the battery voltage?  If it 
measures 3 volts, the battery is probably good.  Less than that and it 
is in need or replacement.

There is one other item that COULD give you the same symptoms.  The 
power adapter could be failing to provide enough voltage under load.  Do 
you know of anyone with a similar computer that has a power adapter that 
you could borrow?  Measuring the voltage of the adapter disconnected 
from the computer is misleading, as the voltage will be higher than when 
it is under load.

I would suggest that if you cleaned the RAM contacts, know the CMOS 
battery is good, and tried another power adapter, you probably should 
not pursue repair on the computer.  The cost could become more than it 
is worth.
We tried to remove it, but its connector came out from the
