New laptop breaks everything

I recently got a Lenovo T420 with windows 10 already installed. Its been great but I think there is something wrong with the USB drivers or something. Only one port shows up in the IDE (also its port 3??) (also its still there after I unplug everything ):). Here's the error message:

"avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x30

An error occurred while uploading the sketch"

Trying different ports doesn't work, trying a different board doesn't work. All the boards are real UNO boards. I've been trying to upload the blink program among others things so I don't think its the code. Deleting the IDE and reinstalling doesn't work either. The board shows up under other devices as "USB serial" and the drivers cannot be updated. I have the right board selected.

I am also try to get used to running Linux lite off a USB on my old computer but that had problems connecting too and I have hunch that solving that will be harder. Very lost what to I do?

As it turns out I have a Lenovo T420 with Win10. I found no issues with Arduino IDE.

When you have a board plugged in got to control panel / device manager / Com port.
Post what you've found.

sorry I saw introductory and beginners and thought that was me l'll move it somewhere else

I can't see a Com port option un the device manager. Plugging in the board does make "USB serial" show up under "other devices", and updating the drivers doesn't work.

Might I suggest a picture from both sides of your board (in focus) so that people may try identify it a little better.


back is pretty blank but i can only upload one picture

Have you installed the CH340 drivers for that CLONE ?
They are not provided by the IDE.
Simply do a forum search for CH340 and you will get plenty of hits with links :wink:

Or read the info I provided !

A clone? I've been lied too...

And just like that its all solved thank you kind sir and have a nice day. I don't know if there's a way of closing the thread now that its all done.

Marked as RESOLVED.
Another happy customer :grinning_face_with_smiling_eyes:

Of course the advantage of running Linux (Mint) - which probably will not install on a Lenovo - is that all the drivers are already provided, :+1:

Not only is that obviously a clone (at least it is not marked as "Arduino"), but it is not actually a UNO. These clones are basically variants of the older Duemilanove as they do not have the 16U2 as the USB interface. :roll_eyes:
