2.Symptom
With regards to motherboards being produced before or during August 2001, the E7-11
problem may result from an exceeded heat resistance margin of the regulator depending
on the usage conditions of the main unit, (the machine is powered up continuously
without being switched off).  For motherboards produced during or after September 2001
the resistance was changed from 4.1
 to 6
 therefore the heat resistance should not be
exceeded.
3. Description
To reduce this problem further a three terminal regulator with increased heat resistance
has been changed. At the same time the parts codes have been changed for the
motherboards.
4. Description
Implemented from December 2004 production.
Reduction in E7-11 problem.
