Serial number for the XO is SHC31100189
I'll keep using it for a few days to check if the repair lasts...

We are aware of a manufacturing process problem that caused what you
observed, but it was fixed some time ago. We know exactly when it was
fixed. When you give us the serial number, I can check if the laptop
was made before the fix or after.
The change you've made sounds reasonable, but it may not last. Keep
monitoring the situation.
p.s. use the devel@lists.laptop.org mailing list for posts related to
XO-4 and unrelated to Sugar. I've intentionally retained all of
thread below.

Tried the test /touchscreen and this message appeared:
missing IR PCB
failed to boot
Tried the command again and a whole lot of code appeared (can't find my serial
dongle so I can't copy it here)
Tried the test for a third time and the message now was:
missing IR PCB
No touchscreen present
I opened the screen and found that the conector for the ZIF cable was damaged
and required some pressure to make proper contact. I just inserted some folded
tape to keep it pressured and it's now working.
No damage or mishandling was given to the laptop on my part so if there are any
other reports of touch not working OLPC should stay aware in case the conector
might be damaged from factory.
Anyway... it's now working just fine :)
Thanks for the info!

You can check the touchscreen from the bios:
* Start the xo
* While the startup sound is played, press ESC key
You will see a "ok" prompt.
* Type:
test /touchscreen
and press enter.
The screen will turn black and you can test it with until 4 fingers.

Hello,
I recently received an XO4 touch to test. As far as I know, it came
with the default 13.2 Sugar image.
Last night I updated the system with yum update "just because". The
touch option stopped working but I just assumed it was due to the
update which might have broken some package or library.
This morning, I flashed the XO with OLPC's stable sugar build to
restore the XO and the touch option is still not working.
Is there any chance the update I made last night might have updated
something that broke the touch option? Some firmware maybe?
Also, is there any way to test if the XO is able to correctly detect
the touch hardware and test it?
I tried to search the mailing list and wiki for this but found no info
available.
