Case 3:
Deleting the Acer Backup Task in the Task Scheduler did not fix your problem. And the window still pops up constantly; the Bluetooth and Wifi still turns off and on.
Solution:
The solution for this is to give up Acer Backup Manager and completely uninstall it from your system. Go to Control Panel, Programs and Features, and select Acer Backup Manager. Click Uninstall/Change on the column header.
This part is quite tricky. It took me more than 3 minutes to complete the installation because the Backup Window keeps opening even during the uninstallation. So Open Task Manager, and End the Process of Acer Backup Manager. Repeat these steps until the uninstall is completed.
Case 4:
Hopefully by now we got rid of the Acer Backup Manager part. But still Bluetooth is a problem.
Solution:
Run Services, click Start and type "services". In this step, we will totally disable the Bluetooth of Acer 3935. I hope you can decide to disable it totally for the benefit of your Wifi. If Bluetooth is more important for you than your Wifi, skip this step.
Under Services, do these. Double click the Service Name (see below which ones), in Start Up Type dropdown list select Disable; and in Service Status click Stop button. Click Ok.
The following services should be disabled and stopped.
- Bluetooth Service
- Bluetooth Support Service
You can also choose to Disable Bluetooth Device under Control Panel -> Devices.
