Hi,

Just before I took my laptop out of its case intending to use it, and when I pressed the start button it booted up, I could hear everything, the backlight in the screen shown up, but I can't see anything.

The screen is just blank, although you can hear Windows booting. Anyone have any idea what's wrong?

thanks in advance.

This symptom (Windows sounds, backlight visible but no image) usually points to a break in the video signal path or failed display electronics rather than a pure software issue. To isolate where the fault lives, use a short hardware-first checklist that avoids needless parts swaps.

  1. External-monitor test: connect a VGA/TV monitor and power on. If the external shows the boot/desktop, the motherboard/GPU is producing video and the fault is inside the lid assembly (LCD panel, inverter/LED driver, or the video ribbon/connector). If the external is blank too, the problem is likely on the motherboard/GPU. Wiggle the display hinge gently while watching the external and internal screen — image appearing only when you move the hinge points strongly implicates the LVDS/video cable or its routing through the hinge.

  2. Non-invasive checks you can do safely: remove AC and battery, hold the power button ~30 seconds to discharge, then boot on AC only. Reseat the memory modules. Shine a bright flashlight at an angle on the panel to look for a very faint image; a faint image + backlight points to backlight/inverter/LED driver trouble, while no faint image points at no video signal to the panel.

  3. If external monitor works and the flashlight/hinge checks implicate the lid, the usual next steps are checking the ribbon connector at both panel and motherboard (requires bezel removal) and replacing the cable or panel if damaged. If the external monitor is blank, further diagnosis of the motherboard/GPU is needed and is typically more expensive to fix.

This builds on the software/graphics possibilities already suggested by and the hardware concern noted by : run the external-monitor and flashlight checks first to decide whether the repair is a simple cable/panel swap or a board-level issue. Take ESD precautions and stop if uncomfortable; a shop can do the connector/panel tests safely.

That is pretty odd.try going into Bios F2 and look at you display settings if it has not set Bios to default and reboot if it does the same try safe mode if it boots turn off hibernate and set to do nothing in the control panel - Display - screensaver - power settings.

You may also need to reinstall the graphics driver.

This sounds like the graphics controller itself might have blown
