Hello. I need help with Laptop Latitude e5540. I have succesfully reinstalled Windows 7 and all official drivers and utilities (from ww.dell.com/support/home/de/de/debsdt1/product-support/product/latitude-e5540-laptop/). All components are working perfect and only three buttons are not working: Mute, Sound- and Sound+
Please send me driver or utility for these buttons.
Looking forward your answer,
Did the audio works itself? Mean, can you play audiofiles etc? There exist no special driver for these buttons. It have to work without any special installation.
Audio works itself. And BIOS signals, and when Windows starts or shuts down, and I can listen songs. I can configure volume by mouse or touchpad, but I need to make these sound buttons also working.
You have said, they have to work without any special driver. I am not sure. After Windows reinstallation Wi-Fi was also not working. I needed to install special driver from dell.com/support. There was also a couple of unknown devices, which have started to work only after drivers installations.
You should help me. Looking forward you answer.
