Solve : Lenovo G550 charging problems?

1.	Solve : Lenovo G550 charging problems?
Answer» I have a Lenovo G550 laptop that will not charge the battery. The battery is good because it can be charged in another laptop. The laptop will work as long as the battery is charged. The laptop will not come on with the ac adapter plugged in. I checked the voltage out of the charger (19 volts). I took a cover of the back of the laptop. There is a PLUG which COMES from the CHARGING port where the charger is plugged in. It plugs into the motherboard. I unplugged it and measured 19 volts there. Is there a simple fix or is this laptop good for parts only?Sounds like the power jack is faulty, if it's a plug in unit then it's a nice simple replacement, rather than needing to solder it like most. It's basically either that or the charging circuit on the board, which would probably require a board replacement - whether it's WORTH it DEPENDS on the cost of the parts.Or a shop can do motherboard repair if charging circuit is problem.
