Question about Gateway MX6030 Notebook
Laptop I found didn't charge battery, and only would work with a battery. so I found a burnt mosfet 4407 chip and swapped it out. Now board will power up off AC, and not battery. No LED showing battery charging. Before charging LED was in error color. Did I solider it wrong? Do I need another chip changed too?
This unit had a RED CHARGE error. Replaced PQ38 solved the problem.
If you get an error on the charge circuit after replacing the PQ38 you should also replace PQ38 because it too may be blown. Make sure Pin 1 where the dots. Also check the MOSFET on the other side of the COIL too.

I've got power problem and burnt PQ38 4407 MOSFET chip. Mine is trying to start from battery but shutts off 5 sec later (with burnt chip)
Looks like PQ37 4411 has to be replaced. Looks like it's also N channel MOSFET
I'm trying to find a source for it.
Let me know if you can find one

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.
If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it
