Sony Vaio - help. Sound and Touch Pad Gone?

[stofferhang]

Hi community!

I hope you can help me. I have a Sony Vaio svs131e1dm.

A week ago the sound and touch pad suddenly stopped working. "sound unit is not installed" and touch pad is just not responding. I tried updating drivers and I even rebooted the computer entirely to its original factory state, but nothing works.

Is it an inverter problem?

Does anyone know how to fix such an issue or is it time for a new laptop?
