Brief expert summary and a focused diagnostic path based on the thread: reported a boot-that-stops-at-a-blank screen and asked which logo appears; noted the panel worked when tested elsewhere. That combination narrows the likely culprits to the video handoff (OS/driver) or the laptop side of the display chain (cable, connector, backlight/inverter, or motherboard).

Useful diagnostic steps (ordered to isolate cause quickly):

  • Observe signs of a boot: HDD/activity LEDs, fan, and CapsLock/NumLock LED response when their keys are pressed. These show whether the OS is loading.
  • Shine a strong flashlight across the screen at an angle. A faint desktop means backlight/inverter/cable; no image at all points toward no signal.
  • Attach an external monitor (VGA/HDMI). If the external shows the desktop while the internal is black, suspect the screen cable, connector at the hinge, or the panel/backlight. If the external is black too, suspect GPU/motherboard or firmware.
  • Try to reach BIOS or Safe Mode (older BIOS: F2/F12/F8 sequence). If BIOS is visible but Windows goes black, focus on drivers/OS. If BIOS is also missing, focus on hardware.
  • Power-reset (remove AC and battery, hold power ~30s), reseat RAM and HDD, boot with minimal hardware. If the internal panel has been proven good on another laptop (as noted by ), inspect hinge cable and mainboard connector next.

If tests point to a board-level fault or the unit is under warranty, arrange professional repair or manufacturer support. For data recovery, removing the drive and using an external enclosure is safest.
