Thanks for your advice.
I updated my software.
I was able to change my BIOS setting on my laptop. However after doing so, I then went to my Yahoo mail account via Firefox. I was unable to compose an email as Compose was dimmed out.
Then I turned my laptop off.
After I turned it back on, I was unable to connect to the internet via Firefox and I was unable to connect to the internet via Skype. At that time I was able to connect to the internet via my PC. My AT&T modem seemed to be functioning normally.
I also received this error message.
“This kernel requires an x86-64 CPU, but only detected an i686 CPU”
Any ideas?
Thanks.
