  2. Hello deepakgera1;

    3 beeps, you say? Can you match your beeps with these codes?

    Yeah it is second one in ur table 1long 2 short. The thing is after the beeps there is no display but window boots up,i can hear the booting sound.Then i have to shut down the laptop 3-4 times.Some times it works some time it doesnt.Not sure what is happening.
  4. Take your laptop apart and check the videocard, it may be damaged or it's not plugged in correctly...
  5. THG article: Report: All Nvidia G84/G86 Chips Defective
    This probably applies to your NVIDIA GeForce 8400GTM graphics card.

    Yeah may be it does.I found a article on sony website saying that these cards may or may not be defective.I contacted sony customer support,as expected no help from them.They are saying i have to replace complete board.Is there any solution u can suggest?
  8. Sony is correct. Only a motherboard replacement will correct the fault.
    You'll need to carefully evaluate the cost of repair against the cost of a new laptop.
