Acer provides online support for its products, including the Acer One. The Acer One name refers to a product line with multiple model numbers. Acer's website provides live chat, repair self-service, documentation and drivers, plus an active online community.
Acer support requests the model or serial number to provide specific information. The label on the bottom of the laptop case shows these numbers. If the label is missing, the Wikipedia Acer Aspire One article has a list of model numbers, including the countries of release and system specification.
Another source of troubleshooting is the iFixit site, which provides repair guides, questions and answers, and general troubleshooting. The repair guides note repair difficulty and tools needed, then provide step-by-step directions for performing the repair.
