Question about Dell Latitude D600 Notebook
I HAVE A DELL C640 AND FOR SOME REASON I DON'T KMOW IT JUST DOEN'T POWER ON AT ALL.
CAN YOU GIVE ME ASSITANCE BY PROVIDING A SCHEMETRIC OF THE MOTHERBOARD TO BE ABLE TO CHECK THE FAULT AND REPAIR IT.
Check the power supply output or try another power supply. Charge the battery in another computer and see if the computer turns on with battery power. If it does then look at FL1 on the bottom of the mainboard near the external power connector to see if the solder on the legs has cracks. I just fixed this same problem on a C640 by re-soldering the legs on FL1 because one was cracked and discontinuous. If you don't have good mechanical/soldering skills you might want to find someone who does. Be careful of heat on FL1 I don't know if it is heat sensitive but I used minimal contact time with the iron and let it cool off between legs and it worked fine.
