Re: broken power button

Apologies for sending this twice, Scott. I forgot to copy the list.



Hi Scott,

    I have the same issue with my power button on my Gateway 200X (which
I think is roughly the same machine as the Dell X200). It appears to be
an issue with fixed-feature power buttons. I opened bug 1920 to address
the problem. You can check it out here:

    Thanks,
    Greg
