Hi there.
They probably had you clear the CMOS jumper or take the motherboard battery out.
The CMOS jumper looks like this >>>>
when power it on nothing comes up. in front has - 82daf9c.jpg
It is the little piece of plastic next to the motherboard battery, if its there move the jumper to the other (on) position for 5 seconds.
If there is not a jumper there take the motherboard battery out for an hour making sure the power cord is removed from the back of the machine.
Please post back if you need anymore advice.

Good luck

P6610f motherboard

Are you following Anti-Static Procedures?

If you, or the person who took it apart has not, you can use the motherboard for a Frisbee.
(Processor for a neck trinket, and Ram Memory for Christmas decorations)


Moving on.........

HP Support > Pavilion p6610f Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?cc=us&lc=en&dlc=en&product=4299342

Product information > Product specifications > Motherboard Specifications, N-Alvorix-RS880-uATX (Alvorix),

A) Let's start with the two power cables coming from the Power Supply, that go to the motherboard;

1) 24-pin ATX main power cable

Looking at the motherboard photo, the 24-pin ATX main power cable's connector; is at the bottom.
Two rows of 12 socket holes, in a yellowish/whitish connector.

Motherboard installed in computer case, you will find it to the Right.

(The motherboard view shown, is clocked 90 degrees to the Right; in comparison to how it actually sits in the computer case)

GENERAL example,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

[NOTE* Color of connector does NOT matter ]

Note the hinged Lock Clip on the power cable's connector.
Also the TAB on the motherboard connector.
When power cable is deemed to be plugged in tightly, and properly; the Lock Clip will be over the Tab.

{Lock Clip operates on the same principle, as a see-saw on a playground. Top is squeezed in to release Lock Clip}

2) 4-pin ATX +12 Volt power cable

Looking at the motherboard photo, the motherboard connector for this power cable is;
Straight up from the white Processor socket,
To the right of the square finned Aluminum Heatsink.

General example of said power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Has a Lock Clip too.
Remember about the color of connector, thing.
Can be pink with neon polka dots. Doesn't matter.
WHAT the power cable IS, does matter.

This power cable is power for the Processor.
It ain't plugged in, you have no computer.

(Scroll down to Motherboard Layout. It is PU521 )

That's it for power cables that plug into the motherboard.
Moving on..........

The Harddrive is a SATA unit. The optical drive is a SATA unit.
(CD/DVD drive)
Means you need a SATA power cable for each one of them.
General example,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note the L-shaped opening in the connector. Hard to see in this photo, but I will show a better view in a minute.

Also; between a SATA data cable's connector, and a SATA power cable's connector; the SATA power cable connector is the larger of the two.
Has 15 contact pins.
SATA data cable connector has 7-pins.

Often there is a lock on this power cable's connector.
A tab that sticks up, or a 'bulb' type affair.
Depress with thumb, when plugging in, or unplugging.

Harddrive needs a power cable, and data cable.
So does optical drive/s.

B) General example of a SATA data cable, and it's respective connector,

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

Just referring to the cable shown at the top, for now.
Now you can see the L-shaped opening a little better.
See how the 'foot' of the L goes down? That is the direction you want it, when plugging in.

The motherboard connector shown below the SATA data cable, is a SATA connector.
This particular style is OPEN.
Your motherboard uses the type that is CLOSED.
Note also the L shape on the motherboard connector.

The connector shown for that SATA data cable, is a 90 degree bent elbow.
If your SATA data cables have this style of connector, they plug into the Harddrive, and optical drive/s.

The straight type of connector, plugs into the motherboard.
It can also plug into the Harddrive, and optical drive; if your SATA data cable has two straight connectors.

The SATA data cable connectors on your motherboard, are all the way to the Left. (In the motherboard photo)

Orange, Light Blue, Dark Blue, and White.
Note that they have a L shape in the middle.

Now scroll down the HP Support page, to Motherboard Layout.

Orange = SATA4
Dark Blue = SATA1
Light Blue = SATA3
White = SATA2

SATA1 is for the Harddrive
SATA2 is for an optical drive.
If you have more than 1 optical drive, it plugs into SATA3.

(Make sure SATA3 is ENABLED in BIOS Setup)

C) The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to; is the Front Panel header.

Looking at the motherboard photo, look again at the Orange SATA4 connector. To the Immediate RIGHT is the Front Panel header,

http://www.findlaptopdriver.com/n-alvorix-rs880-uatx-front-panel-motherboard/

I believe though, that the cable coming from the Front Panel; has one solid plug-on connector. Not individual wires.

Note how the Front Panel header on the motherboard, is missing one pin. This is the Key.
The cable connector going to it, should have one socket hole blocked off.

Should only be one cable coming from the Front Panel, that has the correct plug-on connector.
The other cables coming from the Front Panel, will have different size plug-on connectors.

Going further.........
Look at what is installed in the Front Panel;

USB ports, audio ports, (Headphone and Microphone), Card Reader, etc.
You can follow the cables, and get a pretty good idea of where they go, in the Front Panel.

For example you can follow the cables that go to the USB ports.
Follow the two cables that go to the Card Reader.
Follow the cables that go to Microphone, and Headphone jacks.

Then by process of elimination, you know which cable goes to the Front Panel header.

D) Front Audio
Looking at the motherboard photo, look towards the Top/Left corner.
The Yellow header is for the Front Panel audio ports.
Headphone, and Microphone.

E) Coming down the Left side, in the motherboard photo; look at the two White rectangular headers.
Match up in the Motherboard Layout, and bottom of HP Support page.

USB1 2, and USB1 2.

EACH USB header, is for TWO USB ports.

That is why they both have USB1 2 marked near them, in Motherboard Layout.

A Card Reader SHOULD use two cables, and One USB header.
It may be though, that the Card Reader will use both of those White USB headers.

Either the Card Reader plugs into them, or the USB ports in the Front Panel.
If the cable connector fits, plug that cable in. (On)

USB is USB.
Card Reader uses USB too.

Point?
If the cable's connector fits, plug it in. (On)

In the motherboard photo, there are two White connectors;
Above the Orange SATA4 connector, and Below the Light Blue, and White SATA connectors.
(Light Blue = SATA3, White = SATA2)

The USB ports up front probably connect to them. (Front Panel)
Follow the cables to Front Panel USB ports.
What type of connector do the cables use?

All FOUR of those USB connectors on the motherboard, may NOT be used.
Perhaps just two of them.

That doesn't 'sound' very concise, huh?
However it is my contention, that each cable coming from the Front Panel; should have a different connector.

Going further;
The Card Reader, and the USB ports in the Front Panel; may have the SAME type of connector, on the end of their cables.

Again, the Card Reader uses a USB header, (Or headers), on the motherboard.
So do the two USB ports in the Front Panel.

Therefore it does not matter which USB header on the motherboard, that either one of them are connected to.

F) Looking at the motherboard photo, look above the Ram Memory slots, to the far Right.

Right above ram memory Slot 1, that is White in color. (DIMM 1)
There is a small Electrolytic Capacitor, with a Black plastic sleeve.
Right above it is a small White 3-pin connector.

This is where the Processor fan plugs in.
(CPU_FAN)

G) Right above the square Aluminum finned Heatsink, is the 3-pin connector for the computer case fan.
SYS_FAN
(System Fan)

(The square Aluminum finned Heatsink, sits on the Northbridge chip.
Which is part of the motherboard chipset)

That about does it for me.
Please post additional questions in a Comment.

joecoolvette

How will be i identify it is fully charged battery i charged for 45 minites.But the battery will not be fully charged. please send me the solution for this problems

If using usb charger use usb port on back of desktop, not data port in front, also most laptops do not have fully powered usb ports due to battery consumption. The wall charger, or a usb charger plugged into a usb/ac adapter (like included with ipods and kindles or sold seperately) is your best bet for reliable charge.
Charging unit should have a light on it.
When charger is plugged into power source and not helicopter, the light will show you {#1} what it looks like when battery is fully charged. Typically this is steady on, and usually red. (sometimes green) When you connect helicopter to charger, the light will change (usually goes dark) to signify it is charging {#2}. When light comes on fully (or completely returns to #1) then charging is done. (Note: charging using a laptop usb or a front side data port usb can take several hours.) Watch the light on charging unit when you unplug helicopter, if it gets brighter, helicopter is not charged, plug it back in. Make sure to let battery cool for 10 minutes after every charge and 10 minutes after every flight, and never run battery all the way down. As soon as you can't maintain altitude, land and power off. Fully draining a Li/Po battery weakens it's ability to hold a charge and can ruin it.
If all else fails, replacement batteries are available from Amazon and many others, they are cheap (around 5$) and very easy to install with no soldering and just a small screwdriver.
Hope this helps

Red lite comes on but tv will not power up.

Follow the solution for service port 'jump start' with a usb plug. Plug your cell phone charger in next to the TV. Touch the metal prongs of the service port with the metal part of the usb until you get a brief 'flash' on the TV. Then turn on the tv set. It takes patience and a flash light to do this, so you can see what your touching, as my husband couldn't get it to work, but I could.

Maxtor One Touch 4 is beeping when I connect it by usb

Does the HDD spinup?
My slightly educated guess... the Ext 2.5in HDD requires more power than it is getting from the single port.

1. Try another port
2. Try it on another computer (all USB ports do not provide 250ma to a load)You may be sharing this avail voltage with all plugged in devices and will have to pull 1-2 others to get the HDD online. Since STARTUP current is high, the HDD pulls all it can from the ports (logical) then settles down and uses 1/3 to keep spinning. After the HDD is up and online, try plugging the other USB devices back in, 1 at a time. If it stalls the HDD - you know the why
3. Take it back and find something a bit less power-hungry (Like Hitichi or Toshiba)
