dv6-2150us --> does not power up.

Hi,

     I have a  pavilion dv6-2150us laptop which for unknown reason would not power up. I was working just fine. I shut it down and in a couple of hours would not start. I have kept the power button pressed as others have suggested but nothing happens. It is a dead laptop.

    How do I deal with a computer which wont even power up.

    One thing that I am thinking of is to change the battery. Prior to the loss of power, my battery needed a replacement. I had to keep the laptop plugged in to work. I couldn't work on battery.

     I will appreciate any insights. Thanks

Regards,

Sam
