Touchpad Mouse and Speaker Issue- Toshiba Satelite L350?

HI,

I have recently fixed the faulty internal power connection on my L350 as it was pushed into the case of the laptop by the power cable. To fix issue i had to unscrew the back panel and lift the keypad up to get to the connector and reseat it in its original position. After fixing this issue i restarted the computer to find that the touchpad mouse and speakers on the laptop are not working.

Laptop Model- Satellite L350-170
Part Number : PSLD8E-00D008EN

Any ideas on the cause of the problem and any solutions?

Thanks
