This is a yardsale laptop that I installed fedora on and locked it down (too much apparently).
I set the BIOS PW and set it to be required at boot. Then I stopped using it for a year and now I have no recollection of what I set it to.
I tried popping a watch battery I found in it out and let it sit overnight to dissipate and forget but that didn't work.
Dell won't help unless I can divine the original purchaser's name and address.
Any advice, other than keeping better records in the future?
