A Lenovo laptop repair that recently came through our Boston computer repair shop had a “no power to laptop” issue as it would not take a charge from the power cable.  After first ruling out that the power cable and A/C Adapter (these are the two cables that run from a laptop to the electrical outlet) are not faulty, we

then inspected the connection from the A/C adapter cable to the actual laptop and noticed a slightly loose connection with the DC jack (the internal component that you plug the A/C Adapter power cable into on a laptop).  The suspected resolution was a DC jack repair where we would re-solder the jack onto the motherboard or to purchase a new laptop jack cord, depending on what type of DC jack the laptop had beneath its cover and the damage to the actual jack and possibly even to the motherboard.  However, if re-soldering or buying a DJ jack cord did not fix the issue, then there may have been a short circuit on the motherboard itself which means the motherboard would have to be replaced.  Therefore, the laptop was taken in for a diagnostic.

After carefully taking apart the Lenovo and inspecting the DJ jack cord that it encapsulated, a multi-meter was used to measure the voltages at each end to ensure proper connection, which indeed revealed a grounded wire as the issue.  Fortunately, instead of purchasing a new DJ jack cord, a re-soldering of the cord onto the plug fixed the issue.  After notifying the customer, this task was completed and the laptop was powering on.
