I was given this Mini UI3520 to fix ,was told that they had problems with the old charger and had baught a replacement but are still having problems.
Now I have just had a look online at the data sheet:
Technicaldata Electrical data
Main 40 W
Rated voltage 100 V – 240 V (automatic)
Frequency 50 Hz – 60 Hz (automatic)
Rated voltage 20 V
Max. rated current 2.0 A
And this is the charger they have given me with the Mini UI3520:
FSP Group Inc.
Model no. FSP065-ASC
AC INPUT 100-240V ~, 2A,50-60hZ
DC OUTPUT 19V - 3.42A
Could there be a problem using this charger? there seems a problem somewhere as the machine wont power up, have checked the soldier joints around the power jack socket but these are ok
