Hi all, thank you for intresting for this topic.
I have problem with laptop charger, it works when i plug it in (outputs 19V), when i disconnect it it measures 19V for a few seconds (capacitor discharge), but, when i try and connect the power cable again it doesn't work. When i wait for a idk 15-20-30 minutes, the charger works again. Did someone experienced this kind of problem? I think that it may be that some capacitor in there is faulty.
Thanks!

It may be tripping a protection circuit, then until fully discharged it won't work.
What happens when charging the laptop? If that is OK, then I wouldn't worry about what it does when operating with no load on the output.

When charger works - it works, it charges the laptop normaly but if i would disconnect the power cable (from the wall) and reconnected it after few moments (when the charger discharges), the charger won't work. Then i disconnect it from the wall wait 15-30 min and it works fine.
