Thanks again Dave,
I sort of figured it was like this, but wanted to check with someone --namely you-- a somebody who actually lives there and not in some state of the art Makati condo. I know here is the states, I use a not too expensive surge protector that supposedly modulates surges, but then again--if the electricity just isn't 'there'--it's not going to amp up the juice flowing to the computer and make it run any better.
The electricity is just weird there, ebbing and flowing in different places and at different times--a surge protector can't hurt-they get lightning too. Guess I'll send a few more plug prong adapters, for when they're at home versus college in the city, etc
Computers may be fine running dual voltage,(we'll check for any switch--good suggestion) but I've heard stories of things like made for use in the USA hair dryers and electric shavers frying real quick over there--those babies use a lot of juice.. Hey--the US purchased digital camera we sent with rechargable batteries is two years old and running strong!
thanks again!
