This unit arrived working from a charged battery, but will not power on from AC.
My first thought was bad leg on the DC Jack, Easy job! Finally
Upon opening the case and removing the keyboard I saw the beginning of the failure. Burnt MOSFET under the keyboard directly behind the battery connector.
The visual shows almost the worse case scenario for a shorted MOSFET. Burnt and totally unreadable numbers. Seeing the circuit I surmised that it was an identical pair of chips but I had to verify against another motherboard to be sure. Also there was a scorch mark under the keyboard, but it didn't affect the keyboard or any keys.
Replacing the MOSFETs and soldering broken traces. In this case the GATE line was blown away on both FETs so I got 2 small segments of wire and made the necessary bridges to the GATEs.
This is a common problem with the Dell Inspiron 1501/E1705/6000 series. Most of the motherboards use the same general layout and design. You can tell by the white and silver cases used. From my guess, the solder on the leads of FL1 [filter] tend to lose contact after regular use. Perhaps eating away at the Filters pad, due to the current it is carrying.
Shows another failed NO Charge issue. FL1 cannot handel the surge when plugged in and eventually arcs then lose contact with the solder pad. In this case if you cannot find a replacement, you can simply turn the coil [FL1] upside-down, and make sure you have positive voltage on the circuit. Try to test pad contact area and not just the coil. If you check the coil only, sometimes you may not have contact to the pad, which is the original problem. The silver dots on the motherboard in a circuit are test points. The white dots are only Pin 1 indicators or orientation markers. In picture 2 voltage was checked at pins 1,2,3 to see if voltage reached the MOSFET. This FET sends power to the RUN circuit.
Client arrived stated that she was leaving philippines on the next day, and she wanted to get repaired as soon as possible..
upon checking the mosfet is shorted and need for replacement.
after successfully replaced the fets, her laptop is now working.
