If that doesn't work, the LCD screen needs to be replaced and should probably go to the repair shop since replacing the monitor can be delicate. If the computer displays on the external monitor, the LCD or internal LCD cable could be faulty.
The external monitor key should tell your laptop to connect to the external display. I opened it up and there was only one drop of liquid in the back. Here is how you can get in touch with the phone support. Last night I had a drink get spilt on the back of the laptop, it immediately went black. If the issue persists, I recommend you contact HP phone support to check the available service options for your computer as it may be an issue with the motherboard or the video card.
Once your computer reboots, if it's not displaying on the external monitor, you may need to press the F4 key (or another key with a rectangle box with vertical lines on the left and right-meant to indicate a monitor) on your keyboard. Macbook Pro has lit up keyboard but black screen. Please check if there is a problem with the computer signal interface by using another cable or. Connect to the external display using a VGA cable or connect to a TV as an external display using an HDMI cable, depending on the connections available on your system. Unplug and re-plug the VGA/DVI/HDMI/ 3-in-1/USB-C cable. but after about half hour, the screen suddnly dead. it have been dead first but then turn back on with everything work normal. I can tell when the screen is black due to no power to the laptop and when the monitor itself is on but nothing to. my phone just take s swim in the river yesterday, now its has no display but still on and even the touchscreen is working (i know is working cuz its register sound when i try to touch it everywhere).
I turned it on, and the screen lights up, but it's all black and doesn't display anything. It was purchased with the previous owner not knowing what was wrong.
The hard reset should not clear any of your data from your computer, but it could clear out any driver or firmware errors that might be happening.Ĭonnect to an external monitor to test the LCD and LCD Cable. I just purchased a used HP ProBook 4440s. Performing a hard reset is not the same as factory resetting your HP laptop. Id recommend possibly checking the mainboard, especially the power supply section because one user checked theirs and found that the side where the power.
