This Asus G74 laptop came in with a loose dc jack. You could hold the tip of the ac adapter in just the right angle to get the laptop to power on. We can replace the dc jack for $65 parts and labor on this model.
The G74 is similar to the G73 but with a larger screen. It needs to be completely taken apart to the motherboard to access the power plug. It's also soldered directly onto the motherboard so the proper skills and tools are needed for this model.
When I got down to the motherboard I could see the obvious oxidation of the voltage pin. The G74 uses a six pin, 2.5mm jack that the G73 uses. Like 99% of laptops we de-solder the bad jack and re-solder a new one on for a solid, like new condition.
Once the jack is replaced the laptop powers on and charges the battery again.
