Look on the bottom side of the laptop. There should be small access panels that open by removing one screw. That is where the wifi card is. If there is no card installed then it won't show in the device manager. The HP zd7000 is wireless capable and HERE is a link to cards for it.

memory problem, screen frozen or something disturbing is on block(Like drives) My be the memory.

I have the same model with the same symptoms in for repair. This is a motherboard issue and requires a reflow of the GPU and chipset. It has nothing to do with the LCD because the buttons don't react when the laptop is "turned on". The touchpad turn on/off button does not react when pressed, the same is with the wifi, volume and mute buttons.
The problem is in a poor solder and a cracked/oxidized contacts due to heat buildup.

If the computer won't start--that is, if you push the on/off switch and nothing happens, then you should replace your power supply.
I doubt very seriously there is a short circuit.

Did you try the FN+screen switch key. maybe check to see if nothing is loose ( hdd, ram ) also the bios to see if screen settings are correct

the laptop battery is have't quality problem. need replacing

go on www.hp.com and contact them

Dismantled notebook thinking compressed air removed component or connection. Nothing. Reassembled most of notebook. Left battery and power disconnected for 6.5 hours, I later plugged only AC power into unit. Fans started spinning. Completed assemble of notebook and installed the battery. Blue lights returned. Problem seems to be the battery. Shorts out something and needs about 6 hours drain out. Works great now without battery, using AC power only. Ordered new battery.....

My name is Brian Rentsch. A computer at my sons school was not working because the screen size was too big for the screen itself. To fix it you might have to restart the entire computer.
