Now that there are a significant number of laptops in Peru, high-altitude testing may be more feasible. What test plan would you want followed in order to be able to raise the specs?<br><br><div class="gmail_quote">On Tue, Mar 11, 2008 at 9:00 AM, John Watlington <<a href="mailto:wad@laptop.org">wad@laptop.org</a>> wrote:<br>

I understand your concern. I requested that the laptops be tested<br>
to at least 15,000 ft<br>
operationally, but was ignored. I will inquire into the reasons.<br>
