I bought my 10" dragon express les than one week i didnt use it til 3 days ago When it needed to b charged I took the cord out of the port. The port came with it.

Possibly bad usb socket on the phone

Same problem I also having on my s4150 model.. First I get the problem on the 10th day of the purchase.. and then i have sent my to nikon service center 3 times for the same problem.. Nikon people are saying Battery does not come under warranty.. you have to buy the new battery..

inspect all wiring for flaws and corrosion-new relay will probly help-its up by the batt-new brushes in alternator also--have battery tested--buy a clymer manual

If it was new a couple of days ago I would take it back where I bought it. I bought a power saw and used it once and smoke came out the motor. I took it back and they gave me a replacement.

Isolate the thermostat sensor. Hold it with your hand and see if it comes on and stays on. If so, replace the thermostat.

Most laptops need 24 hours when their battery is first charged - but this is not normal it should last longer than that on batteries- i reccomend charging it for 24hrs minimum with it off then get back to me if that didnt fix the problem

Hope i could help

Comment if you need more assistance

Sounds like it could be the charging port, or maybe the cord itself. You could do one of two things for your first move. Go buy a new cord from T-Mobile, I say this because I bought an MP3 player off ebay, and the cord didnt work when it got here, and instead of sending it all the way back to where it came from, and paying shipping charges on that not to mention the waiting for it to get here, I went and bought a new cord, and it worked fine. Your second option is to just contact the seller, tell them it doesnt work, and go through the hassle of having to send it back, and wait for a new one. The choice is really up to you. If you want to make sure it is the cord first, you could take it to T-Mobile and have them test it. Then go from there. Good luck.

I had a similr problem It turned out that the power supply cord was not the problem, it was the main battery. Luckily, in 2000, I bought 2 extra main batteries. I took out the old battery and put in one the 2 new unused ones and my machine is working and charging perfectly now.

Ok, is the sidekick 3 brand new out of the box or new to you.

The sidekick 3 has an issue with the charging port being bad.

I would contact the person who you bought it from and get a refund.

The other option is to get an external battery charger and charge the battery that way

check the link below for those

wash your hand before u use your camera, the problem is from your dirty hands.

thanks
