Hi jacmom! Welcome to our ALL SPAIN Message Board!
140€ does sound a bit high at that for just a fan replacement. But you know, they charge you to simply accept it and then charge you for their time too. The fan itself probably costs only 20€ but laptops are funky things to work on, not to mention more fragile inside than PCs.
There are PC CITY shops around Madrid, that's where I mainly do my computer shopping, usually the one at Príncipe Pío. Go to
http://www.pccity.es/contenidos.jsp?pagina=tiendas for stores near her but I'd guess the ARGÜELLES location (listed as "PC City Gaztambide " on their website) is closest. She can get there onfoot as I'm guessing she doesn't have a car.
IF she had a car, on the outskirts of the city there are also Media Markt consumer electronics stores. Web:
http://www.mediamarkt.es/ . These places are MUCH more challenging to visit without a car.
Both stores service computers. I'd like to mention that many times the Mom-and-Pop computer stores surprisingly have the best prices and the best service - at least that's been my experience. I used one place near my home but they moved across town. Luckily, lately I haven't needed any computer service.
Some of the "light weight" (and by that I mean less-than-powerful) laptops can cost as little as 400€ and go up from there. It took me awhile but now I'm used to the Spanish keyboard - which is the same as any other keyboard except from of the punctuation marks and special characters are in different places, not to mention figuring out HOW to make an accented character and take a lot of getting used to when writing in Spanish.
Best of luck! Let us know if we can help more. We all love to shop vicariously through others for computer stuff.
P.S. I don't think there's much hope to buy an off-the-shelf laptop (or PC) with an American operating system in Madrid/Spain. For that, she would have to buy online - and even that'd be difficult, I'd guess. But why can't she use the Spanish language OS in the USA? The programs are the same - although in Spanish - and saved documents use the same extensions.
Saludos, MadridMan
