Hi,
When the screen blacks out, shine a torch at an angle close to the screen to see if you can detect if a display is still there. It will be dim but a darkened room will help.
If you can see the display you most probably have a backlight problem.
This can be caused by [depending on laptop model, you didn't say what model you have] a faulty backlight power inverter, faulty backlight power cable, faulty lid switch, faulty video cable or faulty screen.
If you cannot see the display with a torch, connect an external monitor to the laptop and check its' display when the laptop's screen blacks out.
If the external monitor display stays on, then you either have a faulty video cable, faulty video cable connections at either end [motherboard or screen] or a faulty screen.
If the external monitor display also turns off then you have a faulty GPU or motherboard [which is basically the same thing as the GPU most probably is mounted directly onto the motherboard.
Hi,
If you can still 'see' the display when the screen goes black it indicates that there is a problem with either the voltage level of the power supply to the backlighting going intermittently faulty or that somehow the connections supplying the power are going more resistive [as best as I can determine the power from the backlighting is supplied from the motherboard and not a separate inverter board in the laptop].
Just wondering if it could perhaps also be a problem with the software control of the backlighting. When the screen dims have you tried pressing Fn + F6 together to see if you can increase the brightness at all?[Fn + F5 dims the screen]
Here is a link to a webpage that shows how to dis-assemble the laptop. It may help if you wish to see if there is anything obvious such as a loose video cable connection etc on the motherboard Unfortunately it doesn't show how to dis-assemble the lid to view the screen end.

As I cannot find a service manual online, without a schematic diagram it will be difficult to ascertain where exactly the problem is. It may be that you will have to contact a reputable, professional laptop repair service and ask for a quote to repair the laptop
"I'm getting a black screen on my Asus Zenbook now and then. Can someone please tell me how to fix the Asus laptop black screen problem without causing any harm to the system?"
This is a query posted by an Asus laptop user on a leading online forum that I read recently. Although Asus systems are pretty reliable, they can encounter some physical wear-and-tear or unwanted software issues. This can lead to the infamous Asus laptop black screen problem that can be faced by any user. The good news is that there are some smart fixes that you can implement to overcome the Asus laptop black screen of death. Let's get to know about seven of these solutions in detail right here.
If your Asus laptop is getting the black screen display now and then or it is just stuck on it, then you can consider the following suggestions.
Scenario 1: Power light is OFF
This is the condition when the major components of your laptop are not working properly. Also, this might be the case when there is no power supply in your laptop from the AC adapter and thus the device is failing to boot properly. If such is the case:
- Make sure you are using the correct AC power adapter and AC power cord for your laptop that has been supplied by ASUS.
- Check the plugin which you are placing your AC adapter, keep in mind that it should not be loose. If you think the power plug is not working properly, plug it into different outlets.
- The AC adapter cable that you are using for your laptop should not be damaged. Try another adapter if it is faulty
- If your laptop is connected with external portable devices such as a memory card, internet cable, HDMI, CD-ROM, USB devices, etc. remove all these.
- If the battery of your laptop is removable then remove the battery of your laptop and plug your laptop directly with the AC adapter to charge [ignore this step if your laptop doesn't have a removable battery].
- Now we are doing a CMOS reset. For this, remove the AC adapter and then press and hold the Power button of your laptop for about 40 seconds.
Once you are done with all the above processes, turn our laptop on. To do this, we need to reinstall the battery of our laptop [for removable battery models] and connect it back to the AC adapter and press the power button to turn it on.
Scenario 2: Power light is ON
This is the condition when your AC adapter and power cords are working perfectly but the main issue is arriving just because of the other components not working properly. If that is the case:
- Try to turn off/on the display of your laptop and check if your laptop is responding or not. You can do this by pressing the function key [hotkey] [Fn+F7].
Notice: The hotkey's functions can be different for a different brand of laptops.
- If the display isn't responding connect your laptop with an external monitor. Once you are connected with the external monitor, all you need to do is press the function key [hotkey] [Fn+F8] so that you can toggle the displays of the laptop and external monitor. By this, we will be sure that the display is normal on the external monitor.
- If you see the external monitor is responding normally, try to install the graphic driver from the official site of ASUS. [If your laptop is of ASUS brand]
Notice: Make sure you have the latest version of the drivers installed on your computer.
- If you have connected any of the external portable devices like USB devices, memory cards, internet cable, HDMI, CD-ROM, etc. make sure you remove all of them.
- If you have expanded your hard drive before the dysfunction of your laptop, please remove the expanded hard drives.
- Remove the battery if your laptop has a removable battery function, and use the AC adapter to directly charge the device.
- Now it's the time to force shut your laptop. To do so, you have to long-press the Power button until the Power light gets off. Again do the CMOS reset by removing the AC adapter and holding down the Power button for 40 seconds.
Once you are done with all the above processes all you need to do is place your battery back into your laptop followed by connecting the AC adapter. Turn on your laptop.
Note: If you are still facing a problem please seek support for additional assistance from ASUS.
