This test raises the computers core temperature as well as other components to try and warm them up if there are any cold joints on it, But may damage components due to high temperatures. WARNING: Please read the full post that suggests the fix, as it does warn that this CAN cause further damage. If you can't get it to work, try safe mode with networking, if still nothing, I would suggest to bring it to a shop to see if they have a way to test the physical card in a similar laptop or possibly have a new card to test in yours.ĮDIT: This is something I found on the Mobile section of this forum where a fix was found on other HP Dv**** Models, Nothing else comes to mind of what it could be. WARNING: If attempting to remove the wireless adapter card, please be aware that if the card is not damaged, you could damage the card, make sure you are grounded when working inside of the laptop, as well make sure that there is NO POWER to the laptop, this means Remove both the battery and the power cord. You can take the card out, boot up the computer, shut it down, reseat the card, and boot up the computer, see if anything comes up. If you are comfortable with opening the laptop up, on the bottom side of the laptop, one of the covers will likely have the wireless card in side, it is connected by 2 wires, a black and a white, if you go to take the card out remember where each cord goes.

Other things to try - Reinstall the drivers for the wireless adapter, you will need to go to HP's website, type in your DV9500 as well as the other numbers on the bottom of the laptop on a white sticker, located near your prodocut key usually. If that doesn't work and you want to try and manually start the service, reply back that you would like to do so and I will try and step you through it. Rather then get you to go to the exact spot and try and turn on the service, just restart the computer. Hey, reasons for the light not to turn blue could be a problem with the physical hardware itself, being that it somehow shorted or something along those lines.Īnother reason could be that it is not being supplied power, once a computer goes into hibernation mode it is given the right to stop power to that device, and possibly once starting back up, there was no power given to the Wireless? Have you tried to shutdown the computer normally and try it again? Another reason would be that the wireless settings and everything are all controlled by a service, and maybe the service failed to start.
