M18x Keyboard Help

#1
Hello Everyone

Please i need help , My Keyboard and all the controls around it stop working i don't know why

even the mini keyboard or the ( hotkey keyboard ) on the left side is not working

Also all the buttons which located in the frame around the keyboard is not working including the eject
cd & the volumes etc...

I don't know what is the problem , in the beginning i thought it's a cable or socket problem but i found out that
each part have it's own cable the frame is using a different cable .

But the power button is working just fine !!
And it's located in the frame , Right now it's the only button working in this machine is the power button

Also all the lights is working just fine and i can change colors .

Can any one please help me , I don't know what to replace exactly
i was going to but a new keyboard but i'm not sure if this is the problem
May be there it's a chip problem ?!

Any suggestions will be appreciated , Thank you in advance for your attention
