Toshiba M35X

The Toshiba M35X has come through the shop many times over the years for dc jack repair. It uses the same problematic dc jack as the A75, hp zv5000, and ZD7000 which are all common models with the power plug issues.
This M35x had the dc jack broken off inside the laptop (See pic 1) and the older solder would need to be de-soldered.
After installing the new dc jack we make sure to apply plenty of solder to help this from ever happening again.

Averatec AV3225HS / 3200 Series

This Averatec Av3225HS (3200 Series) came in with the classic wiggle of the ac adapter to get it to charge and power on. The 3200 laptops are very common ones I see and fall under the $65 flat rate.
This one uses a three pin, 2.5mm dc jack that's soldered on an small circuit board separate from the actual motherboard. This is nice because if it burns the circuitry or if you drop it the actual motherboard doesn't get damaged.
The dc jack was replaced and the laptop powers on and charges the battery again.

Gateway MX6440 DC Power Jack Repair

This Gateway MX6000 series came in with no signs of life. The ac adapter tested out fine but no amount of wiggling or positioning of the ac adapter would make it power on.
When it was all taken apart I could see the center pin on the back of the dc jack had completely snapped, unable to give any power to the motherboard.
The gateway MX6000 uses a six pin, 2.5mm dc jack that's soldered onto the motherboard.
After a new dc jack was soldered on the laptop powered up without any problems.

Compaq TC1000 Tablet DC Power Jack Repair

The TC1000 compaq tablet is a small 12.1" lcd that's about four years old.
It came in with the dc jack problem symptoms and you could wiggle the ac adapter plug to make it shut off. The dc jack looked worn and loose.
It uses a five pin, 1.65mm dc jack that's soldered into the motherboard.
Soldering the new jack on fixed the problem and the laptop powers on with no problems.

Acer 3680 DC Power Jack Repair

This Acer 3680 came in with the center pin hanging down and very loose. When it was all torn down the center pin had been completely pushed off the back of the jack and was making any contact with the motherboard.
This five pin dc jack is the same jack the hp zt3000 and many other Acer models use. The dc jack center pin is 1.65mm.
De-soldering the dc jack and re-soldering a new one on did the trick. The laptop powers up with no problem and is charging the battery again.

Emachines M6805 DC Power Jack Repair

The emachines 6805 is pretty much the same thing as the gateway 7000 series laptops but with the emachines logo.
This 6805 came in with the classic positioning of the ac adapter plug to get it to charge/power on.
When it was all torn down the voltage pin on the dc plug had broken up and wasn't making proper contact with the board.
Replacing the dc jack fix all the battery charging problems.

Dell Inspiron 700M DC Power Jack Repair

The dell 700M uses the same nine pin dc jack as the popular Inspiron 6000, 1150, 5150, 9200, 9300 as well as the 1505, 1705, and Latitude D Series laptops.
I see all the above laptops mentioned with the dc jack problem.
This 700M can in with the dc jack already broken off the motherboard.
Soldering a new dc jack on fixed the problem.
