1) Both ram sticks are known to be good for this machine ? Install one stick - test it. Then remove the working stick and swap it with the other but use the same socket. Confirm both are working properly.

Then repeat this test using only the next memory socket.

2) Are the sticks of the same vendor / memory density ?

3) You can check the voltage for the non-working memory socket to be sure the socket is being powered. Appears to be powered from +1v35.

Yes both ram are working , tested on other set laptop.
Yes both are same make,FSB , capacity, same too.

I have to check power1v35,on both slot

Just an update, after removing from defective slot ram ,even working slot also stops working/sensing no definite when and how it will start sensing again.
