How I fixed a Dell Laptop that refused to charge the battery and recognize that I was using a genuine Dell DC Power adapter. It took some careful adjustments to the DC jack in the back of the laptop. In addition there is a signal cable that easily gets severed over time in the end of the DC power cable. By making these two repairs, the laptop works perfectly, the power cord stays in firmly, and the battery charges without problem.

Thanks for the tips. For Dell laptops, I would recommend not to place the one on a bed as it will obstruct the fan from running properly and ventilating the heat. Always place a laptop on a flat surface or laptop stand to make sure the fan can run properly, ventilating heat and cooling it down.Find here,how to fix sound problem in dell laptop.
