For North America, it’s 1-800-816-2237.
The phone number is not available anywhere on Acer’s support sites (supposedly, it’s hidden somewhere in the Windows XP control panel, but you can’t get that with a broken computer), so I thought a nice, Google-friendly posting might be in order to help anyone else looking at a broken Acer notebook.
Probably because the number’s so well hidden, I got through instantly to a human being, who (a) seemed to be based in North America rather than overseas, and (b) knew what he was talking about, or at least was able to get answers.
Quoderat 
Thank you so much! I was looking everywhere for this number.
Google FTW!
Finally!!! Thank you so much… I have been looking for this for weeks!!!
Acer is about worthless anyways ill never get another laptop from these guys ever again. Thanks for the number tho. Screws dropped out of the bottom of my laptop 2 weeks after I bought it and 2 months later it quit working and i lost my wedding pictures….All acer had to offer were 3 cd’s to put it back like it was when i bought it for $30.00 more plus shipping. Acer SUCKS in my book
