Re: removing the DC input from a Gateway 7322gz notebook
I tried looking up a manual on how to remove the motherboard on Gateway's support site but they do not provide one. They may have one available that is not published on the site. I would first contact their tech support via Chat and ask if they have one available for download. This would give you specific instructions on how to open the laptop and remove the motherboard so you can replace the DC jack. You will need the serial number from the laptop to open a chat session.
If they do not have one you can try it yourself. I did this myself with my HP laptop and after many tedious hours of work I was able to remove the motherboard, remove the dc jack, and resauder a new one on the board and it worked out perfectly.
If you feel comfortable doing the work yourself first start off by removing the screws on the bottom. You then should be able to remove the keyboard, look for a cable that connects it to the board. Now you should be able to remove the pieces of the case around the keyboard, look for the cable connecting the touchpad to the motherboard. After that you should be able to remove the LCD screen, look for the cable connecting it to the motherboard. Now remove the screws holding the motherboard in and remove the tiny bolts around the external monitor connector and the printer connector if you have one. Now you should have access to the DC jack. You will need to sauder the current one off the board and resauder a new one on. Keep track of the many many screws and try placing the components in the order they came out so will know which ones need to go back in in the proper order.
This is VERY tedious if you are not familiar with working on laptop hardware. You maybe able to find a local shop willing to do this or you can look online for a place that replaces DC jacks on motherboards.

You don't necessarily have to take it apart. Simply taking a vacuum, and putting it close to the fans, while sealing one of them with tape works well enough. I tried this on an old HP and it works well enough. Compressed air is also OK.
If you havent yet received a response, here it is:
First, turn the notebook over so that the bottom is up. Remove the 2 screws at the back (where all input devices are located) and I think also the one above where it is imprinted "Gateway 7322" (w/input rating and such).
WIth a flat-bladed scre driver (I recommend taping the tip so it doesn't gouge the notebook), insert it just under the Internet/email/zoom button - above & between the Prt Scn and Scroll keys. Gently pry up, and get the bezel to pop up some. DOing the same thing, go between the F1 & F2 keys and gently pry up the bezel there. With the LCD Screen all the way open (and flat), use fingers to gently manouver/pry the bezel off - being VERY CAREFUL you dont yank out the flat, white ribbon cable that makes all the buttons operate, which is attached to the bezel on one end and the motherboard on the other. Using fingers on the brown insertion area, gently move upwards the brown insertion socket to allow the white ribbon cable to come out. Too much force will break the ribbon enclosure, causing you MUCH greif and expense!! Take it from experience...lol
