SOURCE: Not sure if Jabra bluetooth headset or charger that not working

I had the same problem, called support, they told me battery is defective or too old and doesn't accept the charge. Battery in a headset is hardwired and can't be replaced, so the whole thing is trash :(

SOURCE: Laptop will not power on.


It is possible that one of the soldered terminals/pins of the power jack of the laptop is disconnected. You can try gently moving the plug of the Charger/AC adapter while connected and see if an indicator light will lit (even if momentarily). If yes, then it is safe to assume that a terminal/pin is loose and would need to be resoldered. If no, then since there is power from the Charger/AC adapter, the laptop's internal circuitry maybe at fault. Most probably parts in the regulator circuitry. This could be as simple as a surface mounted fuse or a 3 terminal voltage regulator. In any case, the unit has to be opened and diagnosed. To do so, you must be familiar with electronic components/circuitry, use of a DVM and a low wattage soldering iron. Should you be uncomfortable with this, perhaps your best bet would be to seek the services of a qualified laptop technician.

Hope this be of some idea/help. Post back how things turned up or should you need additional information.

Good luck and kind regards.

SOURCE: h350 bluetooth headset can't connect to laptop any solution

Do you have the Jabra bluetooth part that goes into your computer? You have to go to your phone settings under bluetooth and make it sync up. Your phone will sync, not your headset. You are trying to sync the wrong thing.

SOURCE: Can't pair my HBH-PV705 bluetooth headset with my laptop

You need to have a bluetooth stack installed, so that you have "bluetooth places" available, where you can link up the headset.
A good instruction (for XP) is shown here.

Bluesoleil is definitely a good option.

SOURCE: Omnitech 2.0 Bluetooth headset. No charge indication?

The AC adaptor, of course, is the unit that plugs into the wall. Problems could be that there is no power to this particular receptical or your adaptor could be broken. I suggest that you try several recepts around your home. If none provide you with a charge light, then your adaptory may be faulty. However, My red indicator light does not pulse as the manual says it will either, yet if left long enough, it does charge.

I need help pairing my B250-XT bluetooth to my Iphone


There are 2 parts to bluetooth. Step 1 is pairing. You need to set the phone AND the headset to detect each other (pairing mode). The phone is the easy part - it will tell you on the screen that it is searching for the headset. The headset has a specific way to put it in detect/pair mode. Sometimes it is holding down the power button for 5 seconds or longer. When the phone detects the headset, it will ask for the password and allow you to name it.

Sometimes, the phones already try the default 0000 passcodes and connect automatically.

Step 2 is connecting to the bluetooth device.

If you are connected and can make and receive calls, you don't need to do anything anymore.

Best of luck.
