Acer 420 manual AC Adapter

All components on inverter board should follow below rules:

1.Component using conditions (component stress) must be within component specification including voltage rating, current rating, temperature etc.

2.Component temperature should follow below:

∆T <=30 degree C, at 25, 35 degree C.

Component temperature should be less than 70 degree C inside system at 35 degree C.
