If you own a Logitech G710+ mechanical keyboard, you probably love its tactile feel and dedicated macro keys. One of its standout features is the customizable white LED backlighting. This makes it easier to type or game in the dark. But what if the backlight stops working? For many users, this can be frustrating, especially since the rest of the keyboard might work perfectly. The good news: there are practical solutions. Whether you’re facing dim lights, flickering, or no backlight at all, this guide will walk you through every step to bring your G710+ back to life. Even if you’re not a tech expert, you’ll find these methods easy to follow.
Why The Logitech G710+ Backlight Stops Working
Before jumping into solutions, it helps to understand why the backlight fails. The causes are usually not mysterious, and knowing them will save you hours of trial and error.
Common causes include:
- Software glitches or outdated drivers
- Physical damage to the cable or internal circuits
- Dirt and debris blocking the light
- Firmware conflicts
- Power supply issues from your USB port
Less commonly, the issue could be a manufacturing defect. But most problems are due to daily use and are easy to fix at home.
Initial Troubleshooting Steps
Start with basic checks. Many users miss simple fixes because they assume the worst. Here’s how to rule out the most common issues quickly.
- Check the Backlight Button: The G710+ has a dedicated backlight key (the lightbulb icon). Press it several times to see if the lights come back on.
- Try a Different USB Port: Plug the keyboard into another port—preferably one directly on your computer, not through a hub.
- Restart Your Computer: Sometimes, a fresh boot resets the keyboard’s lighting.
- Check for Physical Obstructions: Dust or debris can block the LEDs. Gently blow out the gaps with compressed air.
- Test on Another Computer: If possible, try the keyboard on a different PC. If the backlight works there, your main computer may have a driver or USB problem.
If these steps don’t help, continue with deeper fixes below.

Software And Driver Solutions
A large number of backlight problems come from software conflicts or outdated drivers. Logitech’s software manages the G710+ lighting, macros, and other functions. If something goes wrong here, the backlight may not work—even if the keyboard itself is fine.
Update Or Reinstall Logitech Gaming Software
The G710+ relies on the Logitech Gaming Software (LGS) or Logitech G HUB. Older versions can become incompatible after Windows updates. Here’s how to update or reinstall:
- Uninstall the existing software.
- Go to Control Panel > Programs and Features.
- Find Logitech Gaming Software and uninstall it.
- Download the latest version from the official Logitech site.
- Visit Logitech Support for the newest LGS or G HUB version.
- Install the new software and restart your computer.
- Open the software and check the backlight settings.
- Make sure the brightness isn’t set to zero.
- Adjust different lighting zones (WASD/arrow keys and the rest).
Non-obvious tip: Sometimes, the lighting profile becomes corrupt. Create a new profile inside LGS or G HUB, and assign it as default. This can restore missing backlight functionality.
Check For Windows Updates And Conflicts
Windows updates can sometimes break device compatibility. Make sure your operating system is up to date.
- Go to Settings > Update & Security > Windows Update.
- Check for updates and install any available.
Pro insight: If your backlight stopped working after a Windows update, try rolling back the update. Some users find this immediately solves the problem.
Hardware Checks And Fixes
If software solutions don’t help, the issue may be hardware-related. This doesn’t always mean something is broken. Sometimes, hardware resets or cleaning can fix the problem.
Inspect The Usb Cable And Connector
A damaged USB cable can cause lighting problems even if keystrokes register fine. Look for:
- Cuts, bends, or kinks in the cable
- Loose USB connectors
- Signs of burning or excessive heat
Try wiggling the cable gently near the USB plug while the keyboard is connected. If the lights flicker, you might have a loose connection.
Reset The Keyboard’s Power
A simple reset can clear temporary faults.
- Unplug the keyboard from your computer.
- Wait 30 seconds.
- Plug it back in directly (not through a USB hub).
This power cycle can reset the keyboard’s internal controller, restoring the backlight in many cases.
Clean The Keyboard
Dust and debris can block LED light or interfere with electrical contacts.
- Turn off and unplug the keyboard.
- Use compressed air to blow out debris from under the keys.
- For stubborn grime, use a soft brush or a slightly damp cotton swab (never use liquid directly).
Bonus insight: If you often eat or drink near your keyboard, regular cleaning prevents future backlight problems.
Internal Led Problems
If you’re comfortable opening electronics, you can check for internal issues. This is only recommended if your keyboard is out of warranty.
- Remove keycaps using a keycap puller.
- Unscrew and open the keyboard casing.
- Inspect the LED solder points for cracks or loose connections.
- If you see a broken LED, it may need professional repair or soldering.
Warning: Opening the keyboard will void any active warranty.
Firmware Updates And Resets
Some G710+ backlight problems are caused by firmware bugs. While rare, updating or resetting the keyboard firmware can help.
Update The Keyboard Firmware
- Open Logitech Gaming Software or G HUB.
- Go to the device settings tab.
- If a firmware update is available, follow the on-screen instructions.
Real-world example: Several users on forums have reported that a firmware update restored their lost backlight after Windows 10 upgrades.
Factory Reset The Keyboard
The G710+ does not have a dedicated hardware reset button. However, you can try these steps:
- Unplug the keyboard.
- Hold down the ESC key while plugging it back in.
- Hold for 10 seconds, then release.
Some users report this triggers a soft reset. It does not always work, but it’s safe to try.
Advanced Solutions
If you still have no luck, these deeper fixes might help.
Check For Power Delivery Issues
Some computers do not supply enough power to all USB ports. The G710+ requires more power for its backlight than a basic keyboard.
- Always connect to a USB 2.0 or 3.0 port directly on your PC.
- Avoid using USB hubs or splitters.
- On laptops, make sure the machine is plugged into its charger (not running on battery).
Data comparison: See how much power typical keyboards use:
| Keyboard Model | Average Power Draw (mA) | Backlight On | Backlight Off |
|---|---|---|---|
| Logitech G710+ | 150-200 | Yes | No |
| Basic USB Keyboard | 50-80 | No | No |
| RGB Gaming Keyboard | 200-250 | Yes | Yes |
If your USB port doesn’t provide enough current, the backlight may not work or may flicker.
Test With Minimal System
Disconnect all other USB devices except mouse and keyboard. Sometimes, too many devices cause power sharing problems. Boot into Safe Mode in Windows. If the backlight works here, a background app or driver is likely blocking the light in normal mode.
Replace Damaged Components
If you’ve found a physically broken LED or wire, you can replace it if you have soldering skills. Replacement LEDs for the G710+ are available online. But for most users, professional repair is safer.
Pro guidance: If your keyboard is under warranty, contact Logitech support before doing any repairs.
Preventing Future Backlight Problems
After fixing your G710+ backlight, you want to keep it working smoothly. Prevention is easier than constant repair.
Tips to prevent issues:
- Plug the keyboard directly into a mainboard USB port.
- Avoid yanking or twisting the cable.
- Clean your keyboard monthly.
- Keep drinks and food away from the workspace.
- Update Logitech software regularly.
Surprising fact: Many backlight failures are caused by power surges from low-quality USB hubs or extension cables. Always use high-quality connectors.
How To Tell If The Backlight Problem Is Permanent
Not all backlight failures are fixable at home. Here’s how to recognize when the issue is likely permanent:
- Multiple LEDs are out and do not respond to any fixes.
- The backlight flashes or flickers even when the keyboard is the only USB device.
- No light at all, but the rest of the keyboard works.
- You see burn marks or melted plastic around the LED area.
In these cases, replacement of hardware components or the keyboard itself may be needed.
Comparing The G710+ Backlight System To Other Keyboards
Understanding how the G710+ compares to other keyboards helps you set expectations. The G710+ uses white LEDs with two zones: one for WASD/arrow keys, one for the rest. Each zone has four brightness levels (including off).
Here’s a comparison with other popular keyboards:
| Keyboard | Backlight Zones | Custom Colors | Brightness Levels | Software Control |
|---|---|---|---|---|
| Logitech G710+ | 2 | No (White only) | 4 per zone | Yes |
| Razer BlackWidow Elite | Per-key | Yes (RGB) | Many | Yes |
| Corsair K70 | Per-key | Yes (RGB) | Many | Yes |
| SteelSeries Apex 5 | Zones | Yes (RGB) | 10+ | Yes |
The G710+ is simpler but very reliable when working correctly. Its backlight system is less likely to have software bugs than RGB keyboards but can be harder to repair if an LED fails.
