Hi all, I was given a HP zd7000 laptop in non working condition and would like to get it
going because of it's large screen and full keyboard.
It does not boot at all.
The battery was flat when I recieved it. When I plug in the power adapter all
the lights above the keyboard flash on for a second, the On button stays
illuminated as does the charge light on the front edge of the laptop.
The screen stays black, there are no sounds at all, the HDD doesn't spin up,
the cooling fans don't spin.
When I press the On button to turn it off it stays illuminated and won't turn off.
Even holding it in for 10 seconds doesn’t turn the On button light off.
When I remove the power adapter the On button stays illuminated though the
charge light on the front edge goes out, suggesting to me that the battery is
charging while the power adapter is connected, and the On button stays
illuminated for a while until the battery goes flat again.
Things I have tried are:
Removing the battery and AC power, holding down the On button for 10 seconds, to drain any power.
Plugging in the AC power without battery, the On button illuminates.
Removed AC power inserted battery, the On button illuminates.
Plugged in AC power, still the same.
Removed memory, swapped memory, tried both sticks one at a time in both
slots, removed HDD and tested as slave in desktop computer, seems ok, still the same.
Regardless of what I’ve tried, as soon as there is power to the laptop the On button illuminates and stays on until there is no power to feed it.
What I did notice was that the wireless card is missing, but I don’t see this having any effect on the problem
The On button is permanently illuminated as if it is stuck on, though I can hear and feel it click on and off.
Any suggestions would be greatly appreciated.
