Eximo - Thanks for the info and the warning. This may indeed be over my head.

Hey All, I have a laptop that will not power up at all. I'm wondering if there is a way to test the LCD from the unit? Thanks

It's just glue residue. There is a silver foil covering part of the board that sticks down. I peeled it back to get photos and that was some of the gummy residue from it. Very good eye!

Here's a shot of the MAX-1772 and PU3, hope they're clear enough - MAX_1772 And, a couple of extra shots of parts of the board - board_01 board_02 The dark mark right below the "PU3" label is where my daughter marked it with a sharpie. She found it for me and thought that would be a good...

I've installed the new DC jack and now I'm reading voltage of .71 at the battery terminals but the board still doesn't fire up.

Well that's at least a starting point. There may be other issues, as well, because even when I have the cord in a good position and am getting the proper voltage, the board does not run. So once I have a new DC jack in place I'll go deeper.

The cord from the A/C adapter seems to be quite stable. I checked it again and then wiggled it around a good bit and the reading held steady. I get some variances, though, when it is plugged into the MB. With the cord stretched out across the table, for example, I get a good current reading from...

Jaro, thanks for the drawing, it was very helpful. I got a smaller meter to check with and I am not getting any readings from the switch. I also got a better magnifying glass and I have returned to the DC-in jack as the potential culprit. This jack is one that is soldered directly to the MB...

Okay, if I'm measuring the current at the switch correctly, I am getting 4.3 v and it grounds when the switch is pressed. It's hard to tell if I'm on the right connector. I'm going to get a smaller meter tomorrow and give it another look. Bill

Jarotech, thanks for the help. The switch is SW3. I'll check the voltage tonight. Thanks again.

Thanks Schiz. That's what I was Thinking. The connector for the battery has seven blade-type terminals. One is larger than the others, I'm assuming that one is the ground. I checked for power between that larger terminal and each of the others but get no indication of current.

Good Evening, I have a Gateway MA2-6520gz that will not power up. No lights, fan, or any other signs of life with either the battery or AC adapter. I tried the reset (holding the on/off switch down, etc) to no avail. The power brick shows proper output when measured with my meter. I...
