HP laptop just died

so i have an old HP laptop dv1000 series i think its actually a dv1310us - is it like 3-4 years old at least and it has always worked very well for me. well tonight i was typing up an email and it suddently just instantly shut off.

it does not power back on no matter what i do. if i plug it into power, i don't get the charging light on it like i normally do.

any ideas on how to go about getting it to work again?

Also, if you haven't done so, take the battery out and try to turn it on (plugged in of course)

Then, take everything out you can, hard drive, ram, optical drive, expansion cards and try again.

Then if it still doesn't power on, if it were mine, I'd tear the whole thing down and try to power the bare board by itself (nothing connected, no cpu, no fans, no lcd, no nothing). But, that's just me.

The power supply on a notebook is the big black brick you plug into the wall. If that doesn't work, neither does your notebook. Taking apart the notebook is a good step, but checking that PSU is, IMO a step that should be taken first. Does the brick have some sort of LED light on it? Do you have a friend with a multimeter? There are other less formal ways to test it that involve shorting it out and looking for sparks...but I don't recommend you try them.
Other than that, do what dwellman said. Take parts off one at a time, see if some config produces some change. That may indicate the bad part.
