Is it only supposed to show 1 bar while charging in the battery icon

Look on your task bar for the battery icon. If you don't see one , right click the taskbar, click on properties, in notification area click on custom button, the look for b attery icon and have it show on your task bar if not already selected. when your icon appears on the task bar, just hover on the icon, it will tell you the state of your battery

There are usually 4 side by side green bars if the battery is fully charged. You can think of each bar as 25% power, so (4) bars is 100%, (3) bars is 75%, (2) bars is 50% and (1) bar is 25%.

charge to at least 50%. (For storage purposes, so that the battery won't get messed up).
You can tell this by checking the battery indicator (bars, icon or percentage) periodically. If it shows 50% or an icon that shows a battery half-full.
sorry if this was confusing, as I am tired.

Your question was posted under the Nuvi 680 GPS, so I am assuming this is the model that you have.

On the main screen, you will see a green battery status indicator in the upper right-hand corner of the screen. The battery is divided into 4 parts. Each part represents 1/4 power. So if you have one green bar, that indicates that the battery has 1/4 of power left. If there are 3 bars, that indicates that there is 3/4 power left.

When the unit is charging, you will see a yellow lightning bolt appear over the green battery status icon.

When the lightning bolt is not there, this means the unit is running off of the battery.

When leaving the unit to charge, press and hold the power button until you see that the screen says Charging Battery. A few seconds later, the screen will go blank to save energy.

Pressing the screen again later will either say Charging Battery or Battery Charge Complete.

#1 Your BlackBerry does not have sufficient Power
Check the battery charge level as shown by the battery icon on the top left of the home screen. No Power - Battery Charge Indicator does not show a charge or is very weak. The battery icon may be red. Charge the battery.
#2 You are Out of Network coverage area
Check the Signal Strength Indicator on the home screen. (1 to 5 bars, as shown below, indicating signal strength). If there is no signal, you may be out of range of the network.
If you are sure you are in range of the network, but show no signal strength, press Alt-Right Shift-Del at the same time. This will cause the BlackBerry to reacquire a network connection.
The process for this procedure is:

• Press Alt-Right Shift-Del (The Del key is also the Backspace key.)
• The screen will go blank, and an hourglass will appear. Wait for the hourglass to go away.
• The startup screen will appear. Wait for it to go away.
• A screen that says Verifying Security Software will appear. Wait for it to go away.
• Check the Radio Tower icon.

If you are in Coverage Area of your Service Provider, You will get the network.
#3 Your Data plan is switched Off.

If the laptop is old think about changing the battery.

Stelios.

hello,
it is not supposed to make any sound when charging, if it does it means there is a problem somewhere.
it is not charging properly. try to turn off the phone and plug the charger. its supposed to bring up a light the show the battery meter and show it charging bar by bar, if it doesn't come up this way, try using the same charger on another phone to see if the charger is working. anything you detect, try to replace the battery and try again.

you need a new batt.

go to any local phone store to get one.

Apple does have a battery recall/fixing procedure on certain macbooks and macbook pros.

The battery of a MacBook or MacBook Pro computer may:

• Appear to have no charge (zero percent)
• Be unable to power the computer by itself; the computer might work only when it is connected to the MagSafe power adaptor, which only shows a green LED
• Appear with a black "X" icon on the menu bar

1. Shut down, then remove and reinstall the battery. Test for the issue(s) again.
2. Connect the MagSafe power adaptor (if you haven't already) and see if the behavior continues.
3. If the issue(s) persist, download and install the Mac OS X 10.4.9 Update.
4. If the issue(s) persist, Download and install Battery Update 1.2.

If, after installing the Mac OS X 10.4.9 Update and Battery Update 1.2, a black "X" still appears in the menu bar, contact apple by calling 1-800-MY-APPLE (1-800-692-7753)

This has happened to me before,you might want to try using a different usb cable.I did this and it worked fine since then.
