Hello electronics experts,
My lenovo 135W charger ADL135SCC3A failed days after the warranty is expired. With some effort I open the adapter without breaking the plastic and found that first input fuse T4A 250V is blown. This is the first components at the charger grid input and there is a good chance that it protected the rest of the circuit from the external overvoltage. Input is 100-240Vac, 2.5A, output is 20V, 6.75Adc.
Replacing the fuse is trivial, but I wonder if there are some other components I need to check just in case that the fuse is blown due to some malfunction inside the adapter.
Most of the components are covered with some kind of rubber/silicone material and it is very hard to approach them.
Did you have any similar experience?
Any advice is welcomed.
Thank you!
P.S. Notebook is Ok and the battery is charging normally with another adapter. This charger was needed because of the Dock station.
Maybe I made mistake, most of the time adapter was plugged to the power grid even when not used.
Maybe I should have kept it unplugged when not used.
