Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?:(

Thank you

Quick summary and likely cause (short):
The symptoms describes — power LED and fans, intermittent disk/DVD noise, no Caps‑Lock/Num‑Lock LED response and no image on an external monitor — point away from a simple backlight/inverter fault and toward a system-level video/POST problem (GPU or motherboard) rather than an OS-only issue. is correct to flag the era’s known mobile‑GPU failures: some notebook GPUs from that generation had unusually high failure rates and produced exactly this “power on but no display” behaviour. (en.wikipedia.org)

Targeted diagnostics to run (in order):

  • Verify the exact SKU/product number on the bottom sticker (confirm which GPU vendor the unit shipped with).
  • Minimal‑boot: remove battery and AC, remove HDD and optical drive, reseat memory modules and try one stick in each slot (clean contacts first). Try powering with only AC and one RAM stick.
  • Toggle an external display while powering on (HP laptops typically use the Fn+display key; try Fn+F4/F5 on boot) and check for any faint image on the internal panel by shining a flashlight across it.
  • Watch for POST beeps or HDD activity patterns and check whether the keyboard LEDs ever toggle (these are good indicators whether the BIOS completed POST). These are standard HP troubleshooting steps. (h30434.www3.hp.com)

If those steps don’t bring a picture:
No image on both the internal LCD and an external monitor and no POST indicator usually means a hardware fault at the board level (graphics chip or related power circuitry). Repair paths are: full logic‑board replacement, professional BGA reball/reflow (specialist only), or donor‑board replacement. “Reflow” sometimes restores a board temporarily; it’s not a guaranteed or long‑term fix and carries risk if attempted at home. If data matters, remove the drive and recover it first. (ifixit.com)

Recommended next steps:
If the machine is still under any support/repair program, contact HP with the product number. Otherwise have a local pro run the minimal‑boot tests above, then supply a quote for board replacement vs repair (reflow/reball). Avoid DIY hot‑air “bakes” unless experienced — professional diagnosis is the safest, most cost‑effective route for this symptom. (h30434.www3.hp.com)

Firstly nothing will sounds like the good old nvida defect bit of info there. I would say phone HP but it is such a pain in the ass! take it back to where you bought it and they should hopefully sort it if not there is support here. I went through the same thing about a year ago :)

ok that was weird half my post didnt turn up . call / go into where you bought it for and ask for a repair due to your suspicions it is the nvidia defect else if you really have paitence call hp.

on hp site I see that graphic chip is Ati not NVidia.

complete name of notebook is : HP Pavilion dv5027ea Notebook PC

check the labels on your laptop, i only suggested it because it has exactly the same symptoms as that defect :)
