	      Combo PCMCIA Cards May Overheat In ASCENTIA 950N


PROBLEM:

When combo (or dual function) PCMCIA cards are used in the Ascentia 950N 
system, they may become too hot to function reliably.


CAUSE

The excessive heat being generated by the card is a function of the combo 
card itself, and is at the upper limit of the PC Card specification.  
When combined with the heat from the Pentium processor, the card exceeds 
PC specifications.


SOLUTION

This is not something that AST can correct with the current design of the 
Ascentia 950N system.  Future designs should address this issue.  In the 
meantime, customers should use single function cards in this machine.
