Hi everyone, this laptop has 3v and 5v on the coils and also has 3v on the power switch and voltage drops to 0v when pressed. There is no short on the board and the battery charges. I have reprogrammed the bios but still no response to the power switch. Where do I proceed from here?

Try to heat MCP67 by heatgun 300 C 15 sec

Thanks, but I have already done that but still no response. Anything else I should check?

Check LID_CLOSE# AD_IN# PM_RSMRST# PM_SLP_S3# PM_SLP_S5#
Then check PWRBTN#_MCP before and after power button pressed.

Thanks, will check and let you know.
