    While I tend to agree that the probability of both adapters failing is small, how do you know they have not failed? An indicator light, nor volt-meter are clear indications of proper operation. If the supply can't handle the required current load, it will simply cease charging - my first Averatec 2370 adapter failed in this fashion. [and I went through hell to prove this to Averatec so that they would replace just my adapter and not force me to ship in the entire notebook]

    With the above in mind, assuming your stated 'abuse' was not abnormal, it could be the spring contact in the jack is shot. This is not an unusual problem. Still, this means cracking the case and replacing a soldered component. If you don't KNOW you have the skill to do this, pay to have it done.

    May be your 3700 just need a simple fix as the DC jack is broken.

    Check the output of the DC jack by Voltmeter. Pull out the power cable as seen in the picture: red wires are positive and black wires are negative. If there is no voltage reading, you only need to replace a new DC jack. This DC board has a fragile jack and it tends to break easily as seen in 3200 Series.

    This is the first step to verify that power problem is from motherboard which is more expensive to fix.
