Hardware issues are a common cause of why your mouse scroll wheel may stop working. In case of a new mouse under warranty, reach out to the manufacturer to replace or repair the device. Don’t try to repair an under-warranty device, as self-repair will void your existing warranty.

For a DIY, you need to remove the scroll wheel and clean the contacts on both the wheel and the metal disk using isopropyl alcohol. Next, remove all the dirt and debris that is preventing the scroll wheel from contact with the encoder. 

After cleaning the components, put back the scroll wheel and see if the DeathAdder scroll wheel is working again. This can be risky, so do it at your own risk. 

The Razer Deathadder scroll wheel not scrolling problem usually occurs due to outdated drivers, Razer software glitches, or hardware failure. Try updating the driver, repairing Razer Synapse, or fixing the scroll wheel to resolve the issue.
