LG 4010 Charging problem?

I have had my LG 4010 for over 4 yr and now it won't indicate a full (bars) charge while I am trying to charge it. The charger red led light is on. I suspect several things, either one end or the other of the charger has some bad wiring, the phone end of the charger has bad terminals, the phone itself has bad terminal connection or the phone battery has gone bad all at once and won't show a current charging status. I don't know how to determine the cause and I don't have another charge cord or battery for this model/brand. Please advise me as to what could have gone wrong even though the charger LED light is lit ???
I will be waiting for some assistance,

Re: LG 4010 Charging problem?

Your carrier will likely give you a new charger and battery.
there is upgrade credits available and if you do not get a new phone each two years, you probably qualify for some free parts.
one employee told me he told the carrier that his phone was defective and that he could not afford a new one, so he wanted to close his account. they insisted on giving him a new phone instead, at no charge.

The headset contains a lithium ion rechargeable battery, which should be charged before using the headset for the first time.

Operating Systems (when using Windows)
Windows® 7
Home Basic / Home Premium / Professional / Ultimate
Windows Vista® (Service Pack 2 or later)
Home Basic / Home Premium / Business / Ultimate
Windows® XP (Service Pack 3 or later)
Home Edition / Professional / Media Center Edition 2004 / Media Center Edition 2005
(when using Macintosh)
Mac OS X (version.10.3 or later)

Charging the headset

  1. Open the cover of the micro-USB port.
Insert the tip of your fingernail in the groove, and open the cover.
  1. Connect the supplied micro-USB cable to the headset, and then connect the other end to a computer.
Make sure that you connect the plug of the micro-USB cable in the direction as shown in the illustration below.
Charging starts when the headset and the computer are connected.
Make sure that the indicator (red) lights up. Charging is completed in about 6 hours* and the indicator (red) goes off automatically.
*Time required to charge the empty battery to its full capacity
  • If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.
  • When you close the cover of the micro-USB port after charging the battery, push the catch at the edge (the round part) of the cover into the port compartment.
  1. Catch
  • If the micro-USB cable is connected to a computer while the headset is turned on, the headset will be turned off automatically.
  • To charge the headset from an AC outlet, use USB Charging AC Power Adaptor* (sold separately). For details, refer to the manuals supplied with the USB Charging AC Power Adaptor.
  • The headset cannot be turned on while charging the battery.
*Refer to the Reference Guide on the recommended adapter.
If the headset detects a problem while charging, the indicator (red) may turn off, although charging is not complete.
Check for the following causes:
  • Ambient temperature exceeds the range of 5 °C - 35 °C (41 °F - 95 °F).

  • Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave the headset in a car parked in the sun.
  • If the computer enters into hibernation mode while connected to the headset, charging will not be completed properly. Check the setting of the computer before charging. The indicator (red) will go off automatically even if the computer enters into hibernation mode. Charge the headset again in this case.

Red blinking light

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.
•With the Charger Plugged In
•Headset Indicator Headset Status
Red-----------------------------------------------Charging (battery level less than 50% charge)
Yellow-------------------------------------------Charging (battery level more than 50% charge)
Green--------------------------------------------Charging complete
With No Charger Plugged In
Headset Indicator Headset Status
Off ---------------------------------------------Power off
Three blue flashes------------------------Powering on/off
Steady blue --------------------------------Pairing/connect mode
Rapid blue/purple flashes -------------Connection successful
Quick blue flash --------------------------Incoming/outgoing call
Slow blue pulse --------------------------Connected (on a call)
Slow blue flash ---------------------------Standby (not on a call)
Slow red flash ----------------------------Idle (not connected to phone)
Slow purple pulse -----------------------Connected call muted
Steady red ---------------------------------Attempting to connect
Quick red flash ----------------------------Low battery

Note: After 20 minutes on a call or of inactivity, the light stops flashing to conserve power, but the headset remains on

Hope that'll help you in some way.

Bluetooth is plugged into charger but keeps flashing red light, dont know if its charging or not

I had the same issue -- charged it for days and still red light flashing. I was ready to break it open and see if I could replace battery. Then I looked on the opposite end of the charger and seen a little round hole thingy. I put the end of a pen in there and pushed it twice and -- the red light went away . Plugged the charge in and steady red then purple and now blue. Looks like that is a reset ..Try it -- it worked for mine.

All of a sudden my CS 55 with plantronics stopped working. It shows that its on but the headpiece isnt charing and also doesnt work. Any ideas why?

If the Plantronics CS55 wireless headset shows that it is on, you have to make sure of the following things.

a. the green LED on the base turns on when you turn the call switch on from the headset.
b. the small green LED on the side of the headset is blinking.
c. the telephone headset is lifted from the cradle.
d. if the headset is not charging and the Amber light on the base does not blink when you place wireless headset on it; trying placing the headset more firmly.
e. If the headset is not charging and the Amber light on the base does not blink even after placing the wireless headset firmly on the charging cradle, you may need to change the battery.

Alternately you can try resetting the Plantronics CS55 wireless headset.

Reset Plantronics CS50, CS60 or CS55 Wireless Headset

If you have problems with the sound or connection of your Plantronics CS50, CS60 or CS55 wireless phone headset, you may want to try to hard reset it using the following steps:

Note: Ensure the IntelliStand switch (on the right side of the charging base) is in the - position and NOT the = position.

1. Press both the call control button and the listening volume/mute button for 5 seconds. When the indicator light blinks release both buttons.

2. Press the call control button again. The talk indicator light will again blink to indicate the headset is back to normal.

3. Disconnect the AC charger from the AC charging jack for 5 seconds.

4. Reconnect the AC charger.

Now give the Plantronics headset a try.

Purple light

The purple (majenta) light usually means it is in pairing mode. Is it possible that the button is stuck pressed in??


1. Ensure the headset is turned off (indicator light not blinking and headset boom is closed)
2. Press and hold the Call button. After about 4 or 5 seconds, the indicator light becomes steadily lit in magenta
3. Release the Call button and immediately open the headset boom. The indicator light remains lit in magenta.

If the indicator light is flashing in blue or not steadily lit when opening the
headset boom, repeat steps 1 through 3
