Acer laptops are a popular brand due to their low cost and competitive features. Unfortunately, problems can arise during the life of an Acer laptop. A common problem is a broken or loose power jack. Power jacks are the small jacks that connect the power adapter cable to the circuit board. Over time, these jacks can become loose. This prevents the battery from charging, and the laptop may power down randomly. Fortunately, power jacks are relatively easy to repair.
