I was experimenting with my universal laptop adapter (Meind 100W) and when I switched it to 34V mode (while official max is 24V) the capacitor (25V) popped (the top opened and some white fibers spread over the nearby parts).
The capacitor is glued to the board and is not easy to remove. When using the adaptor it slowly heats now.
When under load the output voltage of the adapter drops (and probably recovers after some seconds), so I have to set it to voltage that is higher than needed.
- Is it safe to continue using that adaptor? Can it degrage further with time or it will remain stable?
- How to unglue the damaged capacitor from board?
- Should I use some additional safety measures (for example, external capacitor connected to output) to reduce the risk? (I'm not going to just buy another adaptor)
