Laptop on query

[cactikid]

Odd issue as when i hit the power button my usb fed led comes on but not the screen and have to hold button down to power off.

Powering on again i might hold button down longer and system boots up and light comes on.

It is in use for long periods during the day so unsure what might be happening.

The laptop screen black occurs when there is a corrupted graphics driver or a problem with the LCD display back light. To test the display, you can attach an external monitor and restart the computer. If an image displays on the external monitor, there might be a graphics driver conflict with the display that leads to laptop screen black but still running.
