Not in Sync error on nano that worked fine before

It has been a few months (4) since playing with nano.

I changed computers and updated from 1.6? to the new 1.8.1

the upload error is below.

Here is the code I am using, tried to pare down to the minimum it wont upload...

What am I doing wrong, I just want to upload and all i get is sync errors.

code

void setup() {
// put your setup code here, to run once:
// BLINK NANO LED LIGHT PIN 13
pinMode(13, OUTPUT);

}

void loop() {
// put your main code here, to run repeatedly:

}

error

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Hi,
I had the same problem and traced it down to my 3D printer on and being plugged into a USB port. I turned off the 3D printer and the upload to my Arduino worked.

Try unplugging all your USB ports.

I hope this helps.

Same problem on 2 different computers...
my old one will not upload to the nano with 1.6.1 ish and the new computer on 1.8.1 neither will program a nano

whats up?

@ digger73

Have you gone through all the troubleshooting steps listed in the thread at the top of the forum ?

Could you include pics (decent ones) of both sides of the NANO ?

Does anything show up in device manager when you connect the NANO ? (if so what)
