Here are some of the statements we hear relating to laptop power issues;
"My laptop is dead"
"I have to wiggle the lead to get it to work"
"The port is loose in the laptop"
"The thing where you plug it in is broken"
"My charger is not charging the laptop"
On some occasions it is just the adapter that has given up the ghost and is no longer providing power to the laptop however, 80% of cases are due to the DC port being damaged and not passing charge to the system board to power it up.
Many companies will suggest you need a new system (mother) board which is the most expensive route of repair and most of you would abandon that laptop and buy a replacement. The other option at a third of the price would be to consult a company that will replace the DC port by an affective re-soldering job. We have been doing this at the Laptop Specialist for over 10 years now.
Our biggest piece of advice is for you not to attempt the repair yourself as we promise you, you will regret it as one of our customers did when they tried to glue the port into place and this resulted in an irreparable laptop but it became a great door stop!
