Good call from on testing with an external screen. Since sees no image there either, the problem is almost certainly before Windows ever loads and not the LCD panel or hard drive. When both internal and external stay black, think: no POST. That usually points to RAM, motherboard/GPU, or power delivery.

Try these in order:

  • Do a hard reset: unplug AC, remove the main battery, hold the power button 30 seconds. Plug AC only and try again.
  • Connect a known-good VGA monitor, power the monitor first, then the laptop, and press the display toggle hotkey (Fn + the key with a monitor icon) a few times, waiting a few seconds between presses.
  • Reseat and test RAM: remove all memory, then install a single module in the first slot and try to boot. Swap slots, then try the other module alone. A bad stick or slot can kill video output. If you remove all RAM and power on, a healthy board should emit beeps; silence can indicate a board/CPU fault.
  • Strip to minimum: disconnect the hard drive, optical drive, and any removable cards (Wi‑Fi, modem) and try to reach the BIOS splash. None of these are needed for POST and a shorted device can block it.
  • Watch the LEDs and listen: repeating beeps or Caps/Num Lock blink patterns are diagnostic. Count them; they often map to memory or GPU errors in HP/Compaq notebooks.
  • Check power: confirm the charger light behavior is normal and the DC jack is not loose or intermittent. Try powering on with battery removed and with another known-good adapter if available.

If you still never see the Compaq splash, the most likely culprit is the system board/GPU. At that point, consider pulling the drive and recovering your files with a USB-to-SATA/IDE adapter on another machine.
