Comment 30 for bug 314050

The same problem happened to me just after upgrading my Ubuntu 8.10 amd64 to 9.04 amd64 (I have a Fujitsu-Siemens Amilo Pa 1510).

I thought then download from another pc the image of Ubuntu 9.04 alpha 4 amd64 to try to boot my laptop with the LiveCD, and I got a surprise: If just when I turn on the laptop, I open the DVD drive, my Ubuntu 9.04 boots.

To be more clear:

1. My Ubuntu 9.04 boots if just after pressing the power on button, I press the button to open the DVD drive.
2. It doesn't work if the DVD drive is open when you press the power on button.
3. It doesn't work if I press the button to open the DVD once it has been freezed the boot of Ubuntu 9.04.

I have repeated on several occasions, to dismiss the fact that it was a pure coincidence, and no. Whenever I want to turn on my laptop, I do as I wrote in 1.

Try them to see if it works well on your laptops.
