2. Press and hold the Guide button on the controller until the controller turns on.

1. Press and release the connect button on the console.

Xbox 360 E console Xbox 360 S console Original Xbox 360 console

1. Within 20 seconds, press and release the connect button on the controller.

1. When the lights surrounding the power button on the console stop flashing, the controller is connected.

On the Xbox 360 S console, each connected controller is assigned to one of four positions. Each position corresponds to a lighted section around the console power button and the controller Guide button. On the 360 E console, a solid green light on the front of the console indicates that the controller is connected. To determine the player position associated with your accessory, look at the ring of light that surrounds the Guide button on the controller.

If the controller does not turn on, check the batteries. Insert fresh AA batteries, making sure they are correctly positioned in the battery case.
You can also use the Xbox 360 Play & Charge Kit or the Xbox 360 Quick Charge Kit to power the controller. Learn more about Xbox controllers and chargers.
To connect additional controllers, follow these same steps again. You can connect up to four controllers to the console. Each connected controller is assigned a position that corresponds with the lighted sections that appear around the console's power button and around the Guide button located in the middle of each controller.

• To disconnect a wireless controller, press and hold the Guide button for three seconds, and then choose to turn the controller off.
• When you turn off the console, the controller will reconnect the next time you turn on the console.
• The controller can be connected to only one console at a time. You can connect the controller to a different console, but the connection to the previously connected console will be lost.

Connect a wired Xbox controller
Plug the Xbox 360 Wired Controller into a USB port on the Xbox 360 console. There are two USB ports on the front of the console. To disconnect the controller, pull on the connector, not the cable.
The cable on the Xbox 360 Wired Controller has an inline release. The inline release on the controller cable is a safety feature designed to reduce the chance of the Xbox 360 console falling if the cable is pulled.
Wireless controller troubleshooting
If your wireless controller disconnects or cannot connect to your console, see Xbox 360 Wireless Controller disconnects or can't connect.
If your wireless controller does not turn on or loses power, try the following solutions:
Solution 1: Replace the batteries
Insert a new set of AA alkaline batteries into the Xbox 360 Wireless Controller, and then try to turn it on.
Solution 2: Try a different battery pack
If you have another Xbox 360 Wireless Controller, take the battery pack off that controller and attach it to your controller. Then try to turn your controller on.
If your controller works with the different battery pack, your original battery pack might be defective. If your controller is under warranty, you can order a replacement battery pack from Xbox Support . See the Assistance section at the bottom of this page for more information.
If your controller is out of warranty, you can buy a new battery pack from a retail store.
Solution 3: Try a rechargeable battery packIf you or a friend has an Xbox 360 Rechargeable Battery Pack, attach that battery pack to your controller and try to use your controller. If your controller works with the rechargeable battery pack attached, you can buy a new battery pack from a retail store or order a replacement battery pack from Xbox Support. See the Assistance section at the bottom of this page for more information.

If it has a rechargeable pack on it try swapping it out with a "AA" battery pack. sometimes the rechargeable batteries can go bad. If the controller still won't turn on then you have an internal problem and you will need a new controller. :)
Or you can try getting your controller fixed, although there in not very many people that are willing to work on controllers

Connection problems might be caused by one or more of the following factors:

• Weak batteries or a weak Xbox 360 Rechargeable Battery Pack
• Interference from another wireless device, such as a microwave oven, a cordless phone, or a wireless router
• Metallic objects positioned between the console and the wireless controller, such as a chrome faceplate or metal dividers, shelves, or doors on an entertainment center cabinet
  
  Note All licensed Xbox 360 console faceplates are tested for interference, and do not interfere with licensed wireless devices.
• There are already four controllers connected to the console.

If your controller is still not working, try the next solution.

If you have an Xbox 360 Play & Charge kit

• Make sure that the Xbox 360 Rechargeable Battery Pack is correctly connected to your controller and plugged into one of your console's USB ports. If you check both of those things but are still having the problem, try the suggestion below.
• Plug the charge cable into each USB port on your console, one by one. There are two USB ports on the front of the console and one on the back. If the controller works in one USB port but not another, try another accessory in the USB port that did not work with the controller. If the USB port does not work with any accessory, your Xbox 360 console might need to be repaired.
• Turn off vibration feedback (rumbling) on the controller. If you play games with feedback while charging, it takes longer for the controller to charge and might drain the battery pack faster than it can recharge. Here's how to turn vibration off.
  1. Press the Xbox Guide button on the controller.
  2. Go to the Settings area, and then select Preferences.
  3. Select Vibration.
  4. Select Enable Vibration to clear the checkbox.

If your controller is still not working, try the next solution. Back to the top Solution 3: Remove objects between the controller and the consoleThe controller works within 33 feet (10 meters) of your console. However, objects placed between the controller and the console might reduce this range. In addition, objects that use wireless technology (for example, a cordless phone) can interfere with your wireless controller. Remove or relocate objects or wireless devices that might interfere with the wireless controller or console. Here are some things that can cause problems:

• Microwave ovens
• Cordless phones
• Wireless routers
• Chrome faceplates
• Metal dividers
• Shelves
• Doors on an entertainment center cabinet

Note All licensed Xbox 360 console faceplates are tested for interference, and do not interfere with licensed wireless devices.

If your controller is still not working, try the next solution. Back to the top Solution 4: Disconnect all controllers and headsetsIf all four rings surrounding the power button on the console are green but the controller has four flashing green lights, four controllers might already be connected to the console. Disconnect all of the controllers, and then try to connect the controller with the problem.

• To disconnect a wireless controller, press and hold the Xbox Guide button for three seconds, and then turn the controller off.
• To disconnect a wireless headset, turn the headset off.
• To disconnect a wired controller or headset, unplug its cable from the console.

Opt out the easy way and put a rechargeable battery pack in the controller and use a plug and play controller cord to connect the console to the controller and , voila!, they should be now sync'd to each other.
I hope this helps. Good luck.

if controller does not sync might be a few problems i have noticed on newer 360 controllers they dont work with generic battery packs try a microsoft brand

you have to use a rechargeable battery pack,for some reason those blue controllers and the legendary need the packs or they wont work right regular batterys dont do it even new lithiums wont work.

Well as you probably know all there is to a rechargable battery pack from xbox is 2 generic batteries that connect to the plate that connects to your controller. I recently took mine apart to try and fix it because it was not working at all. If you still have the original battery case that takes the AA batteries i would go out and buy a rechargable battery base and charge the cheap *** batteries that xbox uses in their packs. Then use the batteries that came out of the pack and put them in the original harness. Or you could just use the ones you buy.
