Hi Guys, i know its an oldy but customer wants to pay to fix and its not busy, so...... This 820-2390 keep chiming and high fan spin. Tried to run it with everything disconnected and a new keyboard, same. Before I start check anything, do these have GPU or vram issues? Its better not to try and fix?

Check first resistance (ohm mode) to ground at 3V42.
Less than 30K will point to bad MCP.
However MCP is very old now; maybe not worth to spend time with.
