LED indicator keeps on blinking (red light) but no screen display

There are a few things to check. The LED lights can tell you a lot. This will tell you more about the battery:

1. On the taskbar, double-click the power cord icon or battery icon to open the Power Meter dialog box. Note: If the power cord icon or battery icon does not appear on the taskbar, click the show hidden icons button.
   
2. Press Fn+STATUS to view the power status box, which opens in the upper-left corner of the screen. The power status box shows the current power source, the battery charge level, and the power management mode.
3. Look at the battery charge indicator (if applicable).
   • LED green - Battery is fully charged.
   • LED orange - Battery is charging.
   • LED blinking red - Battery charge is very low.
   • LED solid red - Battery is malfunctioning. Note: This LED only lights up when the notebook is connected to AC power.
     
4. Press the battery meter button on the battery. The battery meter lights indicate the percentage of battery charge remaining.
5. Wait for a Low Battery warning message to appear.

If your battery charge indicator displays what looks like an inaccurate charge, you may need to recalibrate the battery.

To recalibrate the battery as mentioned, try this:

1. Connect the AC adapter and then turn on the notebook.
2. As soon as it starts and you see a startup screen, press the F2 key.
3. In the BIOS Setup utility, use the TAB key to select the Advanced menu.
4. On the Advanced menu, select Battery Auto Learning, and then press the SPACEBAR to select Enabled.
5. Use the RIGHT ARROW key to select the Exit menu. On the Exit menu select Exit Saving Changes, and then press ENTER.
6. At the Setup Confirmation prompt, select Yes, and then press ENTER.
7. The battery recalibration process begins and a screen opens showing you the progress.
8. When the recalibration has finished, and the message "Press [Esc] key to exit" appears, press Esc. The battery charge indicator now displays an accurate battery charge.

Hope this helps!!

Building a simple light-emitting diode (LED) light display can be a great project for both children and adults. A simple LED Display Light can be built using
several LED lights, a resistor and a battery. Once the LED lights are soldered together, they can be mounted in virtually any container or mounted to a board
in a pattern of your choosing.
1.Solder the positive (red) lead of the battery holder to one end of the 1K ohm resistor.
2.Attach the free end of the resistor to the positive lead of the LED. The positive lead of the LED is the longer of the two leads. Solder the negative lead
to the positive lead of the next LED. Continue to wire the LEDs, negative to positive
3.Attach the negative (black) lead of the battery holder to one lead of the push-button switch. Solder the other push-button lead to the negative side of the
last LED.
4.Connect the battery to the battery holder. Activate the push-button switch; the LEDs should light up.
5.Disconnect the battery, if needed, to mount the LEDs to your chosen container.

Yesterday I also got the same problem on Samsung DUOS SGH-D780!
I found temporary solution how to drop this error message and run the phone normally, but after next reboot it often become again. I will ask Samsung tech. support about this, but now here is the emergency solution:

1. Turn OFF the phone (by removing the battery)
2. Move out all the SIM cards from the phone
3. Insert the battery again (BUT DON'T TURN ON THE PHONE, just insert the battery)
4. Insert a charging cable into the phone and insert the adapter in wall outlet

(then I see the loading screen for the short time and after that CHARGING icon appears)

5. After that turn ON the phone. It will start in no-sim mode.
6. Turn OFF the phone
7. Remove battery, insert SIM-cards, insert the battery.
8. Turn ON the phone

After that it gonna be work good until next reloading...

My wife and I both have Pearl's. I found that the problem on both of them was caused by Color Pearl, an application that allows you to change the color of the Pearl's trackball. It was not a problem until upgrading the Blackberry software to v 4.5. I tried rebooting, removing the battery, etc. The light always came back on after an alert. Removing the application ColorPearl did the trick. Just go to Options>Advanced Options>Applications and delete ColorPearl. Hope this helps someone.

Hello,
■ Charging LED 


Charging LED 
Red LED is on = Being charged
Red LED is blinking = Charging error
 Green LED is on = Charging is complete


● If the charge indicator blinks as red, it indicates a battery charging error.
- The battery is not properly inserted
- The terminals of battery are dirty or damaged
If the battery is inserted properly and the charge indicator continues to blink, contact the
nearest Samsung Camera Service Center.


If the charging LED doesn't turn to green could mean a signal that the battery is bad or can't charge 100% anymore = too old, needs a new battery. Hope this helps.

Hello,
Here's a copy from the owners manual:
■ Charging LED 
Red LED is on = Being charged 
Red LED is blinking = Charging error 
Green LED is on = Carging is complete


● If the charge indicator blinks as red, it indicates a battery charging error.
- The battery is not properly inserted
- The terminals of battery are dirty or damaged
If the battery is inserted properly and the charge indicator continues to blink, contact the
nearest Samsung Camera Service Center.


Another charging error is when the batteries are so depleted, they won't charge up to 100% anymore = red light doesn't go out and remains on for too long, means get a new battery.

Hello, it was:

Or if the red LED remains on without turning green could mean a bad battery that no longer charges to 100% - get a new battery. Hope this helps

sounds like a dead battery. Plug the origional charger into it and the front led (below the flash) should flash red. If the red led in the back of the camera flashes or stays lit, then you have the wrong charger plugged in. (the camera won't power up if the back red/green led is on when plugged in)

I have an answer for the 3-2 red light blink w/black screen. Remove the battery, hold the end call button and put the battery back in. The red light should stay on for a while now. Push and hold the call button and alternate with the end call button untill the hourglass shows. Allow some time to boot up. I stumbled upon this, so if this doesnt work, try simmilar procedrues. I did get mine to work. Good Luck, dont give up, it flashes that 3-2 code for a reason.
