Asus UX305 Black Screen


Jan 14, 2018
I have an Asus UX305C with windows 10. Over the last week I noticed the screen would blink black, but run as normal. I was using my laptop yesterday morning, put it to sleep & left it for about 2 hours. When I went to use it again, the screen stayed black despit the power lights coming on. When I hold down the power button, the power light, caps light, and f2 light flash. When connected to power, the charging light is on. Any suggestions on what it could be or how to fix it?


(note: I am unable to remove the battery in this laptop)
To do any of this you will have to cut the power first... and get the computer to restart.

For "Sleep Mode" issues, see if this helps...

1. Go into "Control Panel" and click the "Power Options".
2. Next to the plan that is currently selected click "Change Plan Settings".
3. Now click "Change Advanced Power Settings".
4. Open the "Sleep Setting" and find "Hybrid Sleep"
5. Change/set it to allow.
6. Now click "Apply" and then click "OK".
7. Finally shut down and power up the computer.

Try updating the power management drivers.

First make sure that the laptop is using the most current version of the power management software. If not, update the drivers. Follow these steps:

1. Go to "Control Panel" and then click "Device Manager".

2. Double click and open "System Devices".

3. Right-click "Microsoft ACPI-Compliant System".

4. Now choose "Update Driver Software".

5. Carefully read all the instructions onscreen.

You may wish to also repeat these instructions, but right-click "Microsoft ACPI-Compliant Embedded Controller" in Step 3. (if located on your system)

If this doesn't work, you may need to go to the laptop manufacturer’s website and search their support section and locate any new power management drivers for your laptop make and model.

IMPORTANT NOTE: Do not remove any ACPI entries. Doing so may disable some of your laptop’s power management features, such as the ability to put it to sleep by pressing the Power button. It is also a tad complicated to reinstall those features, so best to avoid the problem all together.

If neither of the above work, try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
