I decided to try Lubuntu on my HP8540w (acquired from an auction my Nephew's company has when they decide to upgrade their laptops) when it came time to upgrade my Ubuntu 14.04 LTS which I really liked. I gave Lubuntu a fair try of six months but I did not like it very much so I decided to install U 15.04 LTS. I usually give the new long term supports a pass until they decide to start beta testing a new version of Ubuntu so I am always one version behind.
The installation got hung up about 3/4 of the way through and would go no farther. I decided to give it another try but I was met with logon screens requesting my user password for the boot option screen, the bios screen and the network options (I just tried those last two out of curiosity) and for the factory reset screen (desperation had set in). The HPElite comes with a fingerprint scanner which is what I used for the bios. It did not work. I used a regular password for the boot options. That password did not work either. I did not set passwords for the other two but one was requested.
I don't believe there is any software on this machine any longer because allowing it to boot up normally got me to a strange login screen that requested my password. It did not accept my password.
So have I turned my wonderful laptop into a big paperweight or is there any solution for this?
