Laptop not charging, not turning on, or only working when plugged in? We diagnose and fix all laptop power and charging issues for Long Island customers.
Laptop power issues can stem from multiple sources: a bad charger, a damaged charging port, a failed battery, a motherboard power circuit issue, or a combination. We systematically test each component to identify the exact cause. We test your charger with a multimeter, inspect the charging port for damage, check the battery health, and test the motherboard power rails. Accurate diagnosis prevents unnecessary repairs and ensures we fix the actual problem.
Charging ports take abuse. Plugging and unplugging the charger thousands of times, tripping over the cord, and inserting at an angle all damage the port. Symptoms include needing to wiggle the charger to get a connection, intermittent charging, or no charging at all. We replace DC power jacks on most laptop models. For laptops with USB-C charging, we repair or replace the USB-C port. Port replacement is a precision soldering job that we handle daily for Long Island customers.
When the charger and port are fine but the laptop still does not charge or turn on, the issue is usually on the motherboard. Blown fuses, failed charging ICs, and damaged power MOSFETs prevent the battery from charging or the laptop from starting. We perform board-level diagnosis using schematics and diagnostic equipment, identify the failed component, and replace it. This advanced repair saves Long Island customers from buying a new laptop when the issue is a component costing a few dollars to replace.
Laptop charging port repair on Long Island ranges from $79 to $199. Standard DC jack replacement for most laptops costs $79 to $129. USB-C port replacement, which requires precision soldering, runs $129 to $199. MacBook charging issues involving the logic board range from $149 to $299. We diagnose the issue for free and provide an exact quote. Call (516) 407-8111.
The most common causes are a damaged charging cable (40% of cases), a worn charging port (30%), a failed battery (15%), and a motherboard issue (15%). We diagnose the exact cause with our testing equipment. Before bringing your laptop in, try using a different charger if you have access to one since charger failure is the most common and cheapest fix. Call (516) 407-8111 for a free diagnostic.
This almost always indicates a dead or severely degraded battery. The laptop works fine on charger power but cannot run on battery alone. Battery replacement restores portable operation. In rare cases, a motherboard issue prevents the battery from being used even though it holds a charge. We test both the battery and charging circuit to determine the right fix. Battery replacement starts at $69. Call (516) 407-8111.
In most cases, yes. We diagnose the cause systematically: checking the charger, battery, charging port, and motherboard power circuit. Common fixes include replacing the charger, battery, charging port, or repairing a failed component on the motherboard. Even laptops that seem completely dead can often be repaired. We have revived many laptops that other shops declared dead. Bring it in for a free diagnostic. Call (516) 407-8111.
