Solved how to start up laptop when the lid is close?

my laptop, HP dv2, have a power button on its right side, not over the keyboard like any other model.
so, i think i can turn on windows by sliding the power button anytime - even the lid is closed.
but it is not like that. i can turn on windows when i open the lid only.

i connect my laptop to TV (as dock, via HDMI port) to work and see movies at home.
now, i change the power setting to do nothing when i closing the lid.
its work out, but i still mess up when i thought that i need to open a lid, turn on, and close the lid again!
i think it should be an easy way to solve this problem.

so i want to know is there any way to turn on windows when the lid is closed?
thank you ^^

There is likely a small hibernate button that is activacted when the lid is closed.

However, where I work, we use docking stations for many of the laptops. Having the laptop on one of those is the only way I know of to startup the computer with the lid closed.

There are also a USB keyboard and a monitor hooked up to it as well as the docking station.

noy work. T^T
but now, i buy a new pc to play at home. so i have nothing to do with this anymore. ^^"
