Dell e1705 will not charge battery any longer

The problem with your laptop unfourtunately is not anything you can simply waive your wallet at, There area on the laptop where you plug in the power Adapter has a very small connector on the inside, this connector because of the nature of the cable and being pulled around and adjusted constantly causes the solder that hold the DC connection in place becomes damaged, sometimes if held in the right position it will charge, but this will only work for so long as the connector becomes more damaged by doing so. Your options are to A.) take the laptop to someone who can solder it back on (literally takes 25-30 minutes) but finding people who are willing to do it is not so easy, i recommend smaller computer shops with Uber nerds (look for the dude with the calculator watch) Option B.) this actually is something that dell covers under warranty as its not damage done by you directly, the damage is done with general use. I would at least try to contact them to see where you are with your warranty. C.) Call Dell's Spare Parts department in the event that your laptop is not in warranty and purchase a motherboard replacement ( seems extreme but its the only way to replace that proprietary connector without soldering it back on ). There is one more problem that could cause this, and that is that the motherboard in your computer has actually started to fail and is not getting the power to the battery, in which case you Have to contact dell, or find someone who will replace the motherboard for you most likely at an hourly rate. if this is the case Go hunting for Dell E1705's with broken LCD's for sale, you will save your self a ton of money, and swapping the motherboards out is really not that difficult, any computer repair place should have the ability.

This solution addresses all the known problems I've seen and should get you on the right path.

Good luck! Stay Classy :)
