Battery Pack or Ac Adapter

It could possibly be the power jack that is inside the computer. This item is typically soldered onto the motherboard and it is what your ac adapter plugs into.

This a battery jump pack that is used to jump start a car. Some units have an ac adapter built in so you can charge the battery in the jump start pack. My unit has a spot to connect the ac adapter to the jump pack so you can charge the battery in the jump pack. My ac adapter has been lost. I know I have to buy a new ac adapter so I can charge my jump pack, what I do not know is if the input (from the ac adapter) is 120v 60 hz
I understand that the DC output needs to dc12v. I do not understand the milliamps. The battery in the jump box is 12v 10 ah ( what ever that is). I just want a new ac adapter to charge the jump pack with that is not going to damage anything.

did jour trie too start whiout the batt ??? only net power ??

Learn how to connect a wireless or wired controller to your Xbox 360 console.
Connect a wireless Xbox controller

1. Turn on your console.
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.

RTFM You can download the manual by googling "acer travelmate 2480 manual" (without the quotes). Or just click here

According to the Acer manual:

"Conditioning a new battery pack
Before you use a battery pack for the first time, there is a
"conditioning" process that you should follow:
1 Insert the new battery without turning the computer on.
2 Connect the AC adapter and fully charge the battery.
3 Disconnect the AC adapter.
4 Turn on the computer and operate using battery power.
5 Fully deplete the battery until the battery-low warning appears.
6 Reconnect the AC adapter and fully charge the battery again.

Follow these steps again until the battery has been charged and
discharged three times.
Use this conditioning process for all new batteries, or if a battery hasn't
been used for a long time. If the computer is to be stored for more
than two weeks, you are advised to remove the battery pack from the
unit.

Warning: Do not expose battery packs to temperatures below 0°C
(32°F) or above 60°C (140°F). Extreme temperatures may adversely
affect the battery pack.

By following the battery conditioning process you condition your
battery to accept the maximum possible charge. Failure to follow this
procedure will prevent you from obtaining the maximum battery
charge, and will also shorten the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by
the following usage patterns:
• Using the computer on constant AC power with the battery
inserted. If you want to use constant AC power, you are advised to
remove the battery pack after it is fully charged.
• Not discharging and recharging the battery to its extremes, as
described above.
• Frequent use; the more you use the battery, the faster it will reach
the end of its effective life. A standard computer battery has a life
span of about 500 charges."

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.

1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
   • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
   • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
   • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
     • If LEDS do not glow and the fan or hard drive do not spin, AC adapter may need to be replaced.
     • If LEDs glow and PC boots, the battery may need to be replaced.
     • If LEDs glow but PC does not boot, go to LEDs glow, fan is heard, but display is black or blank section.
   • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
     • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
     • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
     • If LEDs glow and PC boots, the AC adapter may need to be replaced.
     • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

two possible couses.
first one the adapter is not charging well the battery and therefore the adapter contains a problem.
the second one the battery is damaged.

Your battery pack is not charging. By removing the battery pack and trying to run on AC only you have proved the AC adapter is either not working or the power is not getting through to the laptop.
The best way to sort this is to try another adapter and see if the laptop works, if it does then your adapter is broken (this is possible even though it reads 19.1 under no load.)
If the laptop still does not work with another adapter then the laptop itself will heed repair.

Power Plus Online sell a replacement ac adapter 'PSU 1' at www.power-plus.tv we purchased one recently for £29.95 and this works fine.
