Let me look around for you.

The plastic front of the computer is the Front Panel. The area of pins on the motherboard that the wires from the Front Panel attach to, is the Front Panel header.
Sometimes there are two Front Panel headers.

This information may be tough to find.
What is needed is the manufacturer name and model number, off of the motherboard.

There were several different motherboard manufacturers used, and several different variations.

I'm going to post two links that may help you with identifying the motherboard manufacturer, and model number.

Look in the middle of the motherboard, around the edges, and in-between any expansion slots on the motherboard, for identifying nomenclature.

http://www.pcpartsohio.com/gateway.aspx?c=2&s=91

Going further, there is a motherboard chipset on the motherboard.
The motherboard chipset consists of the Northbridge chip, and the Southbridge chip.

The Northbridge chip will be covered with an aluminum finned Heatsink. It's identifying model number/letters will be covered.

The Southbridge chip usually does not have a Heatsink. It's model number/letters will be easily identifiable.

The Northbridge chip and Southbridge chip are installed in a mated pair.
A specific Southbridge chip will be used with a specific Northbridge chip.

This means that identifying what Southbridge chip is used will lead us to what Northbridge chip is used, without removing the Heatsink off of the Northbridge chip.

This shows you a motherboard diagram, detailing how the motherboard chipset is connected to the rest of the motherboard,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

This general example of an average motherboard shows you the Northbridge chip, and Southbridge chip,

http://en.wikipedia.org/wiki/File:MicroATX_Motherboard_with_AMD_Athlon_Processor_2_Digon3.jpg

Looking in the middle of the motherboard you will note a bl;ack square Heatsink that looks like a meat tenderizer.
This is the Heatsink over the Northbridge chip.

To the left of the Northbridge chip, and to the left of the ram memory slots, is the Southbridge chip.
It has VIA on it in white letters.

State any identifying letter/numbers that you see on the motherboard.
Please state in a Comment.

Hp TouchSmart 310 wont start,power light flashes


The LED light has now turned into a diagnostic light. The fault is a bad Power Supply.
Replacing it however, is easier said than done.

I don't know what exact model of the Touchsmart 310 series you have.
(Examples such as TouchSmart 310-1000Z, or 310-1125f, or 310-1155y, etc.)

The TouchSmart 310 series of All-In-One desktop computers, has a battery, and an AC adapter, (Charger), for power.

Test the battery with a multimeter set to DC Voltage.
{Symbol is a dotted line over a solid line. If there is more than one DC Voltage setting, set it to 0 - 50 Volts }

Should be close to 18.5 Volts (DC)

Battery is low?
Check the AC adapter (Charger)

The middle metal cylinder of the plug that goes into the computer, is Positive.
The outside metal shell which surrounds it, is Negative.
Again, 18.5 Volts (DC)

Check both then post back in a Comment.

Gateway computer 310 series wont power up when


It sounds to me like the power switch is plugged into the motherboard incorrectly. I would need to know the type of motherboard you have to get you the proper schematic for hooking up the power switch and reset switch to the board. If you have the manual to the motherboard, there should be a detailed picture showing you how it is to be hooked up. Please let me know the motherboard model for further assistance.

Good Luck,

My gateway 310 series desktop will not power on, it was powering on and immediately powering off


sounds like your power supply. try another power strip. try plugging it into another outlet. try the monitor power cable instead of the power cable from the tower. If none of these works, and you get zero power, you need a new power supply.

System wont turn on and there is a solid green light at the top of the mother board of my gateway 310 pc replaced batt on motherboard and it still wont turn on.


hello, this be caused by several things , i am assuming your are okay with opening up a PC since you have already changed the onboard battery.

here are few things you can try to further troubleshoot:
1: though the ligh on motherboard is on, power supply can still be faulty, so lets test that with a paper clip trick,
follow this link there are pictures and very clear instructions: http://www.ehow.com/how_4732521_test-desktop-power-supply.html
if power supply is bad, well then you know what to do... change it.
if the power supply is good:
2: remove all the RAM (memory) chips from motherboard and plug the power cable back in and observe the response (you may or maynot hear THREE beeps) now plug in memory chip and try powering up and try with one chip at a time...if PC boots up with any of the chips in it you knkow you have a faulty memory.
if that didn't work:
3: with everthing put back together try disconnecting just the hard drive and power it to see if you see BIOS screen.
if not:
4: many time this worked for me with Gateway PCs, reseating CPU in its slot but only do it you feel confident doing it because you can end up with a GIANT door stop if any of the pins on the CPU are/is damaged.
you would need some thermal-paste to go back on between CPU and heatsink.
if that didn't work..i think you are up to buying new PC.

let me know if you need more help or not clear about anything...
good luck

No power


Did the service tech actually look at the computer? I don't know how anyone could make this diagnosis without doing some testing. It could be the motherboard but it could be something else too. I would first suspect the power supply. They frequently go bad. Test that.

Monitors wont work


It appears that you have a faulty graphics card.
If the graphics card is integrated with the motherboard then it cannot be repaired. Just purchase a new AGP graphics card, insert it into the AGP slot and connect your monitor to this card.
You may need to go to the BIOS setup to disable the on-board graphics card.
If you don't have an integrated graphics card, then buy a replacement graphics card.
You will need to install the new graphics drivers after installing the graphics card.

My gateway 700 xl doesnt boot


Unplug the power from you 700xl and from you monitor. Try removing the cmos battery and reinstalling it. Then, plug everything back in and try restarting. If it continues to give you the yellow light, you may need to replace the CMOS battery, especially if it is more than two years old.

Another thing to consider is if your power supply is underpowered for the number of external devices you have plugged into it (i.e., cd, dvd, external hard drives, printers, pci cards, etc). Gateway installed very low powered power supplies in their 700xl desktop computers. Usually only around 250 watts maximum.

If you are replacing the power supply with another 250 watt maximum power supply, and you have a lot of external devices plugged in, you may need at least a 350 watt power supply....if your CMOS battery is not the problem.
