Turn the system board over and Disconnect the power-adapter port cable in picture from the system board. Note corrosion on the cable which was done by water.

This Dell Inspiron has the CPU integrated with the system board. See picture. Be aware of this if you are replacing the system board which will cost you $649. 99 from Dell. The cost of this laptop is $699. By the time you read this costs might be down, but be aware of this pitfall.

This concludes my discussion of this laptop. Other parts of the laptop were not included.
