Hello! I have a Taichi 21 that doesn’t turn on the internal screen. I would like to upgrade to Super I/O, but I didn’t find it in any I/O programmer. Can you help me? Thanks

Hello @fhsenna

Do you mean a non-touch screen?
I have one too, when you do a fresh install if video card drivers are not installed, second screen doesnt work.

Now, if you have all ok and think the problem is on SIO, you can program it with SVOD for example (Its ITE, right?).

Hello, @mvisionpt

Thanks for the answer.

The touch screen works. Although the internal screen does not turn on, I can press the shortcut and go to the external screen.
Because of this I think the problem is the SIO.
However I did not find the file for SIO ITE IT5422 to try to install.
Is your SIO this model too?
Thank you very much
