How do you change controller to mode 1 on bugs

Try changing your power settings.
Go under your Control Panel. Then access your Power Options. Edit when to turn off computers display.
This should get your power save mode to prevent any errors/bugs.

Disable BIOS password and it will work properly. It's a BIOS bug.

If the issue just started and you use McAfee Antivirus, it is likely a update they had that went awry.

One of your "switches" to your burners is shorting causing unit to spark when in the off mode, or, you may have a bug problem, bugs have made their way into the spark module.

1: if no bug problem, disconnect stove from electricity, lift top up, remove all of the single connections to each switch to top burners(make sure they don't have any bare wires touching the frame), then plug unit back in, if still sparking then replace module.

Remote control has mode select switch, set it on DVD-1 to control Recorder with remote.

I'm sure are still young in the computer world. You know bugs are error on a program while virus are program made by us who can destroyed other program. You might not listen carefully your teacher, he can't really put bugs in your computer but he can put programs with bugs of course. To tell you frankly all software have bugs in it, thats the reality.....

Please don't forget to rate it......thank you
