We have an Intel AMT machine for development purposesand todayIgot a surprise!
After I power up the machine I press F2 to enter Bios Setup and then usbkeyboard freezes!, so I can not do a thing; I first thougth It was a keyboard problem so I changed it to another one I'm sure It works, but Bios freezes again.
Then I thougth it migth be a USB port issue so I let the machine entering Windows Vista and the keyboard worked OK (I'm sending this email inside machine).
According to what I experienced I'm sure it's not a physical problem and I don not thinkIt's a software problem cause machine has been always the same configuration.
Here some aditional data:
-Keyboard works OK before and after Bios setup booting, but it does not work during (or in) Setup.
-Keryboard's Bloq number led keept on while freez.
-Bios setup doesn't freezes itself becauseI can see system time moving.
-Machine does not have PS2 port (only USB).
-I have been googling it and I justfounda similar post http://www.xtremesystems.org/forums/archive/index.php/t-99298-p-3.html(see the blacksun1942 user post) but tIt wasdue a BIOS update.
-Intel AMT version is: 3.2.1
-See screen shots attached for hardware info.
We have seen issues in the past when you try to switch from Enterprisemode to SMB but your case is the other way round. You are saying that after working with the SMB mode, you got into the Bios and changed it to Enterprise mode and then the Bios freezes?
Could you do a CMOS reset and see if that helps? for this,
I have followed steps1 to 5, but when the Bios setup menu loads I can not type a thing; I mean, keyboard still keeps inactive with Bloq Num led turn ON; but trouble does not have to do with keyboard cause if I let sytem loads OS keyboard works OK.
I cannot find in this thread what system you are using? You are using an OEM system, correct? Which one? And since this is a problem that you have been having prior to doing any AMT updates or configuration(correct?) have you checked to see if your OEM has a newer and improved version of the AMT Firmware for your system on their support site? Also, youmay just need to "reflash" it with the latest firmware. Either way, your problem sounds like it may be beyond our capabilities in this forum so as Sree said, it's probably a good time to contact your OEM and see if they can give you any further insights on what might be happening.
Please let us know what you find out.
