Replacement DC Jacks
When it comes to repairing electronic devices such as laptops and notebook computers, sourcing replacement parts can sometimes be extremely time consuming and sometimes you’ll end up in a situation where you simply can’t find the right part. This challenge is a particular problem for newer models, where compatibility issues and limited availability are often the case (or the manufacturer doesn’t supply components; only complete motherboards).
When it comes to USB-C ports, it’s even worse. There are no standard mounting-leg layouts or pin configurations (or even port lengths) between manufacturers, resulting in so many different types.
Searching for a Power Socket
We had our work cut out for us when the Lenovo Miix 510 laptop belonging to a very desperate owner, ended up on our repair bench. The problem was a faulty power socket (also known as a DC jack or charging port).
The only information we had was the laptop’s model number, so we started searching eBay and AliExpress in an attempt to locate the correct replacement part.
Manufacturer Support: The HP and Dell Advantage
Some manufacturers, such as HP and Dell, make our lives easier by providing comprehensive service manuals. These manuals include illustrated parts lists, complete with part numbers. Armed with this information, technicians can quickly identify the required components and search for them online, using the respective part numbers. Unfortunately, not all manufacturers provide this documentation, leaving us to rely on alternative methods. On larger components like a LED screen, it’s a matter of removing the screen to find the part number printed on the back. Not so easy with small items like the power socket.
Thanks Lenovo: No parts available!
Despite our best efforts, we couldn’t find an exact match for the Lenovo Miix 510’s power socket. Our searches online yielded similar options, but none precisely matched the original. Faced with this dilemma, we had to get creative.
Masters of Modification
We weren’t about to give up yet so we bought a power socket from eBay that looked like the closest match, going by the photos the supplier provided. The socket arrived a day later and after removing the old socket and clearing the solder out of the holes, we tried it out. We were hoping like hell but unfortunately it wouldn’t fit the laptop’s motherboard. The mounting legs didn’t match the existing holes. Nothing lined up and frustration began to set in. However, we pride ourselves on our resourcefulness. This wouldn’t be the first time we’ve had to substitute the closest thing we could find and make it work.
1. Bending and Filing: Armed with a Dremel multi-tool, we carefully bent and shaped the mounting legs. Precision was crucial; too much force could damage the delicate components.
2. Soldering Expertise: With our newly modified power socket in hand, we soldered it into place. Patience and a steady hand were essential. The laptop’s functionality and our client’s sanity hung in the balance.

The Advantage of Adaptability
Our persistence paid off. The Lenovo Miix 510 laptop now has a functional power socket and it’s securely soldered to the motherboard. It required some ingenuity, a bit of craftsmanship, and a willingness to adapt. While we couldn’t achieve a perfect match, our resourcefulness saved the day.
