Having problems with your Dell Latitude D600 Notebook ?

Have known good ac adapter. Plug it into computer and the power light on the adapter goes out. Have replaced the DC jack on the motherboard. Where else could the short be located?


Answers :

Try looking for the onboard power regulator which is typically a 3 terminal TO or TAB packaged device with a heatsink and is most likely labelled as LMnnnn where n can be any number (if it has any markings at all). Also try unplugging all the peripherals to see if any of thiose are dragging down the power then add them one by one.
