Hello my friends .
Dell Latitude 3400 3500 BOLT-L DIS (18750-1 R4GHW)
Got this lap with no power on , after diagnostic i suspect bios..try 2 official version and with one the lap power on but off after 30 seconds.
No short to GND , no post internal and external , no corrision , no VCCGT ( and i think it's normal )
Behaviour : power on , consumption reach 0.740amp with variations....fan not spining at all..than before POST it turns off.
All the voltages are presents , power sequences are ok , pltrst is present , charger circuit is ok , ram circuit and power circuit are ok.
What i m missing to check !!
