Laptop don't come on
Can't turn on my laptop there is a light on the on button which makes me believe that it's not the battery that's a problem , it's a problem with the screen
A series of Pavilion branded laptop computers manufactured by Hewlett-Packard from 2008 that featured a 17.3" diagonal display. Available with an AMD or Intel processor.
If you believe it to be an issue with your screen I would connect it to an external monitor temporarily to see if you can get a picture to come up. Also, try removing the battery and having it connected to wall power and try powering on the device. Place it on a counter so nothing touches the prongs for the battery. Please note you may need to use the FN key with one of the function keys sometimes blue on the keyboard to get the monitor to work. Check your users manual for specifics.
