Machine: Dell Inspiron 1150
Symptoms: (1) on pushing power button w/ battery in, power light flashes twice, battery light flashes once and nothing else (2) w/ AC adapter and no battery, power light flashes once, nothing else. (3) same symptoms when drives, memory, modem, keyboard, display stripped.
So far: replaced palm rest and replaced system board, but same symptoms.
Curious whether it is something with the fan. When fan plug removed, power light stays on for a few seconds, then off.
