re: Question about computers

It depends on the quality of the adapter and how you're connecting it to the power source. A lot of converters that people use are simply not meant to power these types of devices, especially not for any extended period of time. Most decent manufacturers will have adapters that are designed to be able to deal with it, but you can't just assume that it'll function correctly. It's most likely stemming from improper grounding, though. Whether it's some sort of ground loop or just bad converters/adapters, it's not unlikely that it could cause problems. Most modern hardware is built to handle that sort of thing, but again, improper grounding and unclean power could definitely do damage.

Even though most of the adapters are probably capable of dual-voltage, it's very possible to experience hardware issues and strange behavior in these situations. While I doubt it's causing software issues, the issues could just appear to be software related and really be related to an issue with hardware.
