An HP ProBook 440 G11 with a black screen, a screen that stays dark though the laptop seems to be running or a display that flickers has a short ladder of checks to climb, and the first step is to find out whether the laptop is on. This is a mainstream business 14-inch laptop with an Intel Core Ultra processor, a 1920 by 1200 panel and Windows 11.
The checks in more detail
A black screen can be a power state, a brightness or display setting, a driver or a hardware fault, and each has a quick test. First, is the laptop on? Listen for the fan, look for the power light and the keyboard backlight, and press the Caps Lock key to see its light respond. Plug in the charger and leave it for 30 minutes, since a flat battery looks like a dead screen. Shine a flashlight at the display at an angle; a faint image means the backlight has failed, not the laptop.
Press the brightness-up key and the key that toggles the display, and press Windows, Ctrl, Shift and B, which restarts the graphics driver and may bring the screen back with a beep. Then test an external monitor: connect one by HDMI or USB-C and press Windows and P to choose Duplicate or Extend. If the external monitor works, the laptop's graphics are fine and the internal display or its cable is at fault. Do a hard reset: unplug the charger, hold the power key for 15 seconds, release it, then plug in and start.
If the screen comes on at the HP logo and goes black when Windows loads, boot into Safe Mode through the recovery menu and update or roll back the graphics driver, or use System Restore. Run HP PC Hardware Diagnostics UEFI with F2 at power-on to test the display. If the external monitor works and the internal panel is dark in every test, the panel, the cable or the backlight needs an HP repair; quote the product number from the underside.
