Viper Ultimate blinking red.

The red LED that is visible on the photo is the profile LED - it has nothing to do with battery. If you cover up the sensor with finger, the LED should be disabled (ofc if the sensor works properly).

I already said it is not a common low battery problem. LED blinks no matter covered or not

Can you give more details like mouse work or not. If not working on wirless work on wire etc. Mayby it is only a led issue that you have ?

The mouse doesn't work at all neither it is direct wire plugged nor wireless, nor docked. There isn't any cursor movement or any driver response from the PC. It only keeps flashing red. Another thing I found out is that I tried using the firmware update tool to fix it but only the dock is detected and updated. The update software doesn't detect the mouse when I plug it in. The same goes to Synapse. What I suspect is the sensor not working any more. But how to fix the sensor?

From what you write you need to cheack if windows see your mouse. If you have mouse connected before remove the windows driver or connect it to different of you should have new device connection sound and mouse should appear in devices on windows device manager and in windows control panel under devices. If on your pc or different pc don’t show most likely it will be pcb failure and repair will give new mouse cost. If windows will see the mouse but only cursor will don’t move yeah it will be sensor and you can find guides on Google or send local shop for repair if someone will do it.

Something on pcb can cause this. You can find on after market mouse with broken shelf or sensor and try to donate parts but how this will looks or how long will work no one can tell you.

Has anybody tried ultrasonic wash before?

Dont recommend putting device that have battery inside on any liquid no matter what it is. Next Like wrote above if the sensor was broken on your mouse windows still should see device in worst case give you op-up window that not recognized usb device is connected. Broken sensor should only prevent mouse from moving the cursor.

Just plug the battery off to wash anything else. Are you sure all the things you said are solid about the how the sensor works?
