Hello, I have a faulty 2007 MBP that I want to sell for parts. Before doing so I need to erase all the data, but when I press the power button nothing happens so I can't access any files. The power button makes the drive sound but not chime. I've taken the battery out and tried a SMC reset. I've also put the Install disc in but it just whirrs then ejects itself. Any ideas how I can access or wipe the data (it is backed up but ideally I'd like to double check I've got everything)? I have a MBP 2011 I can transfer the data to. Thanks.
