Battery, Sound and Trackpad not working

Hello,

I have a lot of problems with my MBP wich affect that the sound, battery and my internal trackpad doesn’t work correctly.

So I decided to reinstall the MBP, but it doesn’t work.

# battery will be not detected furthermore and charging doesn't work, too.

1. trackpad settings have disappeared. I can see a searchingmode for a bluetooth trackpad device only.
2. sound is not working. Not via internal speaker or headphones

I tried it with a reset of the SMC and PRAM/NVRAM but it doesn't work and now I'm not making any progress.

I hope someone can help me to fix this problem.

Many thanks and best regards

Timo
