Hi,<br>
I have a couple of XO laptops, XO1.5 and XO4, the models with the<br>
non-membrane keyboards, where several keys stopped working.<br>
Is this common? Is there a recommended fix?<br>
<br>
Thanks<br>
Regards,<br>
Sebastian<br>

I've not seen it happen myself.<br>
<br>
I've had no recent reports of it.<br>
<br>
We continue to make the keyboards, so I'm interested in any wide<br>
area systemic report, so that I can feed it back into manufacturing.<br>
<br>
The array of key switches may be connected in a matrix. A key switch<br>
that does not release can cause several keys to stop working.<br>
<br>
To check for this, use our keyboard self test.<br>

On my XO1.5 that I got from the peruvian deployment (from the Ministry<br>
of Education), I tested this, and have found there are two "columns" of<br>
keys that don't respond:<br>
<br>
F1, 2, w, s, x, <><br>
and<br>
F8, 8, i, k, ;<br>
<br>
It has latinamerican/spanish keyboard.<br>
The right shift key sometimes appears stuck. It is not responding now.<br>
However when within the OS, I'm sure there were other keys as I couldn't<br>
type "l" or "g" keys.<br>
<br>
On the XO4 I couldn't figure out how to reach the keyboard self test.<br>
"menu" command in ofw triggers an OS boot selector (linux/android)<br>
instead of the test.<br>
<br>
If it helps I believe this may have to do with the fact that we just<br>
moved to the rainforest and have experienced very high temperatures (up<br>
to 40 C) for the past six months.<br>
<br>
I can inquire if more people have found this issue at the ministry if<br>
you like.<br>
<br>

<br>
Ok, sorry, I figured it out now. This wording was confusing to me (or I<br>
was too fast):<br>
<br>
pressing down the left hand side of the "Rocker<br>
<<a href="http://wiki.laptop.org/go/Rocker" rel="noreferrer" target="_blank">http://wiki.laptop.org/go/Rocker</a>> switch" to the left of the screen<br>
<br>
I was confused be cause I was pressing "down" instead of "left".<br>
<br>
Anyway, the result I get is:<br>
All keys seem to work fine, except F1, which appeared stuck in the<br>
beginning and now doesn't respond.<br>

<br>
Thanks for the reply.<br>
<br>
These keys not responding suggest either;<br>
<br>
- a broken column circuit in the printed circuit underneath the keys,<br>
e.g. due to impact, corrosion, or latent defect,<br>
<br>
- a broken column circuit in the flexible circuit connector, e.g. due<br>
to thermal cycles over a long life, or foreign substances, or<br>
<br>
- damaged keyboard controller chip, due to electrostatic discharge<br>
carried from fingers.<br>
<br>
What you might do;<br>
<br>
- disassemble the bottom,<br>
<a href="http://wiki.laptop.org/go/Disassembly_bottom" rel="noreferrer" target="_blank">http://wiki.laptop.org/go/Disassembly_bottom</a><br>
<br>
- expose the flexible circuit connectors,<br>
<br>
- look for mold, fungi, sugar, coffee, or other signs of invasion,<br>
<br>
- unclip each cable, clean the connector surface with isopropyl<br>
alcohol swab, allow to dry, and reclip,<br>
<br>
- test before full reassembly.<br>
<br>
Given the age of the laptop, there is a risk of breaking the retaining<br>
lever on the connectors.<br>
<br>

<br>
Hmm. Then it is also possible that key switches are not releasing.<br>

<br>
That's odd. It doesn't happen if I type "menu". Q7C05.<br>
<br>
Either type "test /keyboard" or use the left rocker key on boot to<br>
enter the self test menu.<br>

Perfect growing conditions. ;-)<br>

<br>
I remember now a deployment report that counted the number of<br>
keyboards replaced due to wear. It was a reasonable percentage, and<br>
seemed to follow a statistical normal distribution over time.<br>
<br>
I think there's risk of distorting the statistics if we ask, so I'm<br>
quite willing to hear of statistics but not go look for them.<br>

<br>
In the test, hold Q down. Press E. If it does not respond, then the<br>
key switch F1 is not releasing. Tested here.<br>
