Activation problems

[John Watlington]

I have two laptops here in Peru that refuse to activate.

I have generated leases for (increasingly) 7 days, 3000 days,
and 7999 days, and none work.   I activated three other laptops
using the same key/activation request and they work fine.

They boot up and don't give any error messages.   They just start
flashing the SD, USB, and finally WiFi icons.   When activating,
they don't give any error message, they just say "Powering off in 10  
seconds".

Any suggestions ?
