Fujitsu Lifebook T series (T731) laptop/tablet problems

Hi dear friends.
My laptop model is Fujitsu Lifebook T series (T731) .
I installed opensuse leap 42.1 on it and I have some hw driver problems :
1 - Display Multi-touch not worked . its very useful to zoom in/out in office / browser / pdf reader /… softwares with two finger .
2 - internal Bluetooth hardware detected but could not found any other bluetooth devices . I resolved this problem with an external bluetooth device .
3 - finger print sensor not found .
4 - Sometimes opensuse ask my saved wifi password again ! It seems that forgets his password.
5 - webcam device not found .

my laptop data sheet and hardware specs

How can I resolve this problems ?
