Having problems with your E-Machines (T2824) PC Desktop ?

Might have messed up jumpers on t2824 motherboard

\015 I was adding a second hard drive and vaccumed the motherboard to get some dust off it. Now I get the green light on the motherboard but it won't power up. I checked all the connects and swapped the power supply with another e-machine with no change in result. I'm wondering if I pulled jumpers off pins. There are several pin sets that have no jumpers.\015

Answers :

There are normally unused sets of pins. What I suspect is that you managed to pull off the plug that connects the board to the front power button and indicators.

Unfortunately I couldn't locate a drawing of the board for you. But if you look at the bottom of the case you will find several wires that come through a hole in the front and end in a plug. The wires are usually 3 or 4 sets of twisted pairs, and normally it's a 10-pin plug at the end. The plug will probably already be near the jumpers on the board where it plugs on, typically near the bottom edge. (I know I'm using a lot of "probablies" and "usuallies" but all boards aren't the same. Most are this way though.) The pin will be arranged in two rows of 5, with a pin missing atthe end of one row. There may be label on the board saying someting like "F_PNL" or "JFP" or it may have individual markings for "PWR" and "IDE_LED" and such. If you see either of these you're in the right place. The plug will have one hole plugged so you can't put the plug on backwards. And even if you did it wouldn't hurt anything. You'd just have to turn it around. Once you get that reconnected your machine should come on as normal.

If this has helped you out, please take a moment to rate my solution. And thanks for asking here!
Try unplugging the hard drives completely.

Will the computer boot up now?

If not you probably fried the motherboard. Vacuums create a lot of ESD.
