Zerodate T26 Troubleshooting (2025)

Wireless Connection Not Working

When using the wireless mouse, the mouse either does not respond, does not connect, or stops responding after some use.

Low Battery

If the mouse stops responding after gradual use even when the USB is connected to the computer, then it's very often due to low battery. To fix this, plug one end of the charger into the front of the mouse and the other end into the computer, and wait an hour before testing to see if the mouse works. Also, please note that there is an on-off switch on the bottom of the mouse, and turn that off when charging and on when the mouse is in use.

Disabled Connection Port

If the mouse is completely charged, it may be an issue with where you've plugged your USB. Unplug the USB from the computer and move it to a new port. If you need to clean the ports on your laptop, please refer to this guide or any similar ones you may find.

Worn Out USB

After many years of use, a common problem is that the mouse takes longer to connect to the computer you are using. This is because the USB stick might be worn out, slightly bent out of place, etc. In this case, it's recommended you replace the USB with one of the same Zerodate brands to keep the same software and use the mouse again. The guide linked below provides step by step instructions on USB replacement for the Zerodate T26.

Mouse Not Charging

Mouse is not charging correctly when plugged into the computer.

USB Port Disconnection

While the mouse could be connected to the mouse just fine, there might be problems with the connection to the computer. Unplug the charging cord from the computer and try to plug it into a different port. If needed, clean the other ports on your computer until you're able to charge the mouse.

Dirty Charging Port

Similarly to a dirty USB port, the charging port on the actual mouse itself might need to be cleaned out. With isopropyl alcohol and a small cotton swab, gently wipe away any dirt, debris, or hair from the mouse's charging port. Wait 15 minutes for the port to dry before trying to plug the mouse back in to charge.

Worn Out Charger

If the charger has been used an excessive amount, there's a chance that it might be worn out. If that's the case, purchase a replacement from any standard electronics store and begin charging again.

Broken Charging Port

Another common problem for the mouse not charging is a broken charging port. If that's the case, disassemble the mouse to take out the charging port, and instead replace it with a new one. Make sure the computer mouse is off while you disassemble it to avoid any possible danger, and off while you charge it again.

Cursor Delay

The mouse cursor moves too slowly, quickly, or stuttering across the screen.

DPI Function Not Accurate

DPI is the measure of mouse sensitivity, and often on computer mice, you can change this function according to your needed sensitivity. Adjust the DPI function of the mouse by clicking the button to set desired cursor speed. This button is located on the top of the mouse right below the scroll. Changing this function will make the cursor move faster or slower.

USB Connection Issues

Another reason behind a stuttering cursor is connection issues. Try to move the USB into a different port to see if that works better, and clean the USB ports. If that doesn't solve the problem, the USB from the mouse may be worn out and need to be replaced.

Low Battery

If the mouse hasn't been charged in a long time, then there's a chance that the cursor will begin to stutter in response to a depleted battery. If that's the case, turn off the mouse and plug the charger into the mouse connected to the computer. Wait an hour before turning the mouse back on to test if it works.

Cursor Not Responding

The mouse is turned on and the USB is in the computer, but the mouse cursor is not moving.

Not Connected To Computer

The USB might be plugged into the computer, but it's not fully connected. Try to move the USB into a different port to see if that works better, and clean the USB ports. If that doesn't solve the problem, the USB from the mouse may be worn out and need to be replaced.

Low Battery

If the mouse has a low battery, the cursor may register on the screen but not move when you tell it to. Plug one end of the charger into the front of the mouse and the other end into the computer, and wait an hour before turning the mouse back on to see if the cursor responds.

Blocked Sensor

On computer mice, wireless or otherwise, the sensor on the bottom of the mouse is used to detect the surface underneath it and to move the cursor across the screen when the sensor deduces movement. If you are on a highly reflective surface, like glass, that could lead to the sensor not detecting movement, and if that's the case, you should move to a new surface or purchase a mousepad. Another solution is to gently clean the sensor with isopropyl alcohol and allow it to dry for ten minutes before using it again, ensuring that any gunk or debris has been cleared.

Broken Sensor

If the sensor on the bottom of the mouse isn't able to detect any movement because it isn't functioning correctly, then the cursor also won't move on the screen. If the sensor is clean, and you're on a flat, non-reflective surface, then there's a good chance that the sensor itself is broken and needs to be replaced. Gently disassemble the mouse to get to the sensor and replace it, and put the mouse back together again. Ensure the mouse is charged before use. The guide linked below provides step by step instructions on CMOS sensor replacement of the Zerodate T26.

LED Lights Not Turned On

The RGB lights surrounding the mouse aren't working when the mouse is turned on.

LEDs Are Turned Off

There is a button located on the top of the mouse that controls the LED light settings. The LED is controlled by the lowermost button. There are seven light settings, with the seventh being the LED lights off. On the bottom of the mouse, make sure that the on-off switch is turned onto the setting labeled "light". Press the button labeled with a lightbulb again to turn it back to the first setting. Change the setting by pressing the button multiple times.

Low Battery

An uncharged mouse might also be a cause for the LEDs not working. Plug one end of the charger into the front of the mouse and the other end into the computer, and wait an hour before turning the mouse and the lights back on to see if it works.

Worn Out USB/USB Port

Another common problem for the RGB lights not turning on is worn out or dirty hardware, either on the mouse itself or the computer. Try to move the USB into a different port to see if that works better, and clean the USB ports. If that doesn't solve the problem, the USB from the mouse may be worn out and need to be replaced.

Burned Out LEDs

After lots of use, the RGB lights can be burned out, just like any other lightbulb. If that's the case, then disassembly of the mouse is required, and the lights must be carefully removed and then replaced. The guide linked below provides step by step instructions for LED replacement of the Zerodate T26.

Mouse buttons work and it connects to the computer, but scrolling up and down does nothing.

Dirty Scroll Wheel

The scroll wheel, because it's a small pocket within the mouse, dirt, and debris can cause the scroll will get clogged and the wheel won't move or register on the screen. If there is a small amount of debris, firmly blowing on the scroll wheel can push out any small bits clogging the inside. If it's visibly dirty and blowing doesn't do the trick, take the mouse apart to clean the wheel AND the sensor inside with isopropyl alcohol.

Dirty Circuit Board

If it's not the wheel itself that's the problem, it will often be because the circuit board has been dirtied somehow by spills or trapped debris. To clean this, take apart the mouse to access the circuit board and gently clean it with isopropyl alcohol, and let dry for at least 10 minutes.

Broken Scroll Wheel

The scroll wheel itself could possibly be chipped, which causes a large problem when it comes to the sensor trying to read the movement of the wheel. In this case, the scroll wheel must be replaced. In order to do this, you must take the mouse apart to take the wheel out and replace it with a brand-new wheel. The guide linked below provides step by step instructions on scroll wheel replacement of the Zerodate T26.
