The Aspire 4720Z is a notebook computer made by Acer. There are several possible reasons the computer may not be powering on: the connections may be loose or damaged; the AC adaptor or power cord may no longer be functioning; the battery may be defective or no longer working; or the battery may need to be reset or recalibrated. If these methods do not solve the issue with your Acer Aspire, contact Acer support for further troubleshooting options.
