Default Water Damaged 820-2936-B

Hi I have a water damaged 820-2936-b which i have ultrasonic cleaned the board and got it turning on etc. It runs really slow with laggy mouse but i think this is due to the voltage sense circuit. I have a schematic but could really do with a Board view file to locate components on board.
Any help would be really grateful!!!!

Hi diif,

Can you help me to identify the board based on the photos ?
I think it is a 820-2936b board and equal to this boardview K90i ? If this is correct then a lot of components (26) are missing on my board ? Can you see the photos also if i am correct ?

thanks for your reply
