[] Sampling Procedure -

ONE LAP TOP PER CHILD COLD STORAGE TEST:

METHOD

Each of 5 laptops is subjected to 6 trials of extreme cold storage temperature. The first three trials repeatedly subject the laptop to -25C for 24 hours, then the laptops are moved into 25C at 85%RH for one hour before booting up (turning the laptop on). A successful boot up indicates the laptop has passed. The second three trials decrease the storage temperature to -50C for 24 hours at a time, then again the laptops are moved into 25C at 85%RH for one hour before booting up (turning the laptop on). Each of 5 laptops is subjected to 6 cycles of intense cooling followed by warming to room temperature. The results are shown above.

Via client and project handler temperature and humidity was changed to 32C and 88%.

Samples were charged prior to testing.

Only those products bearing the UL Mark should be considered as being covered by UL.

* = Sample 1, SHF70600420, Sample 4, SHF706001C2 and Sample 5, SHF7060039E, operated as they had before with one exception. After the fourth cycle all three of the samples' displays had a dimmed appearance. The displays were still readable but were not clean and clear.

After the fifth cycle finished Sample 1, SHF70600420, the display did not operate at all. The Power LED lit up and was green proving the sample was ON, yet the display was completely dead, no activity. Sample 4,SHF706001C2 and Sample 5, SHF7060039E, the displays lit up to a white screen and did nothing else. The Power LED and the two LEDs on the bottom left of the display lit up on both samples proving that both samples were ON and running, yet the displays remained white.

After the sixth cycle finished Sample 1, SHF70600420, the display did not operate at all. The Power LED lit up and was green proving the sample was ON, yet the display was completely dead, no activity. Sample 4,SHF706001C2 and Sample 5, SHF7060039E, the displays lit up to a white screen and did nothing else.
