Lenovo Yoga 9i Black Screen

Does your Lenovo Yoga 9i have a black screen? This problem page will go over several common occurrences when it comes to a Lenovo Yoga 9i screen not turning on. The problem can be caused by either software or hardware causes, so read on to determine the right solution for you!

This may seem trivial but a restart of your computer is the first thing you should try. This tends to fix some innocuous issues.

• Press and hold the power button for 10 seconds. If the computer was powered on but not displaying anything, this will force restart it.

Another good first step is to plug in the Lenovo laptop. Is the screen black or does it need to be charged?

• Make sure the laptop charger is plugged into a known good power source and let the laptop charge for 15 minutes or more.

Sometimes screen brightness settings go so low that a functioning screen can appear lifeless, especially if there's glare or you're in a bright outdoor environment. Use keyboard shortcuts to increase brightness.

• The keyboard shortcut to increase brightness is likely either:
  • Fn + Home
  • F6

Try a software fix by restarting the video driver. This works in Windows 7 and up.

• Use this keyboard shortcut to restart the video drivers: Windows Key + Ctrl (Control) + Shift + B.

The computer could still work well, but the laptop display is broken or disconnected.

• Use a separate monitor to test if your computer is outputting anything.
• With the external monitor plugged in, use Windows Key + P to cycle through various display setups.
• If only the external monitor works, the laptop screen itself or a cable connecting to it may be damaged.

Try charging your laptop for 15 minutes and then power it on. If the battery is severely discharged, leave it charging for longer.

• If the battery is faulty, a battery replacement is necessary. Follow along with a guide like this to see how the repair is done.

If you are using Windows, boot into safe mode to troubleshoot the issue. Safe mode uses a basic driver that will let us view the screen if it is a software issue.

1. To boot into Safe mode, hold the power button for 10 seconds to power off the laptop.
2. Press the power button to start the laptop.
3. Do this 2 more times to get Windows to boot into a recovery environment.
4. You will see Choose an option at the top of the page. Navigate using the arrow keys to Troubleshoot > Advanced options > Startup Settings > Restart.
5. Windows will restart and show a menu of options. Choose Safe Mode with Networking.
6. Uninstall the corrupt graphics drivers from Device Manager and reboot the computer back to regular Windows.

If Safe mode does not work, the boot partition might have been corrupted. Windows will need to be installed again.

Reseating helps to reconnect any loose connections to your laptop’s memory. As laptops are taken places in backpacks or slammed down on desks, the RAM may jostle slightly. Reseating the memory ensures a solid connection.

• Power off your laptop, remove screws, pull RAM out, remove any debris with an air compressor, reinsert RAM, and power on your laptop.

If you uninstalled the graphics driver in Safe mode, you can have Windows search for new drivers for you.

1. Open the start menu and search for Device Manager.
2. Expand the Display adapters section and right-click on the display device that comes up.
3. Choose Update driver and in the pop-up window choose Search automatically for drivers. Windows will search for new drivers and install them.

If none of the solutions above had any effect and your device is showing signs of life (keyboard lighting up, making sounds, etc.) and you're sure your problem isn't just that the device is failing to turn on.
