Q: This charger is for a Dell laptop that I only used as a backup laptop to my main computer. I have had the charger since 5/2014 but have only used it for about 6 months of that time. Recently I plugged it in to recharge the laptop with 40% left and the charger itself was completely dead. Its plug has a blue light on the end so you can see if it is on and nothing. Curious, I cracked it open to see what the failure mode was. Its case is not meant to be opened and had to be forcefully pried apart. Once apart I found it totally encased in potting cement to keep its components unmovable. This unfortunately made it impossible to troubleshoot because you could not get to the components to test or repair. From the reviews, it looks like about 2/3 of these charges work OK and 1/3 go out in short order. This charger label says it is an Original Dell that I ordered from TexasDiscountElectronics but not sure if a knock off or not. This seems to be a problem with many of the replacement chargers but there is little recourse but get another one to try. I don't know why they can not make a reliable charger like true original ones that come with laptop new and last for years.
