SOURCE: D20 Diode value on Motherboard.
Contact Dell support. Tell them that you were told by a tech (that has repaired many of these problems) that you believe you have a motherboard with leaky capacitors (do not mention the burnt out diode, just tell then it no longer boots). After much interaction with Dell technicians, it turns out that dell has extended the motherboard warranties of most of their PC's including laptops. I know of two people so fat that have had Dell warranty repairs done, even though the system was out of warranty. Once they hear "leaky capacitors" they will advise you that even though your unit is out of warranty, they will replace it. Hope that helps! Best regards
