When the DC jack goes bad, it can seem impossible to find someone who can make the fix. These parts are hard to find, but we can help you replace the power jack in your laptop. There are a few different reasons why you might need to replace this part. In most instances, the DC jack is loose because a piece of material has been accidentally dropped into it, preventing the jack from making proper contact with a power adapter. If this happens to your computer, remove the battery and netbook ac adapter from the laptop, and try cleaning out the jack with some compressed air or by using tweezers to pull out any small piece of debris from the port. When that doesn’t work, then it’s time to replace the DC jack. The first thing you’ll want to do is gather all of your tools, which includes: a new power jack for your laptop, some needle nose pliers, an electric screwdriver and finally, a plastic scribe that can be purchased at any local electronics store.
