Nero is a nice VCD Burning software.

I'm thinking that is the symbol for your internet browser home page. There is a button/key which opens your browser on your home page. That light may never go out - if it's just an indicator of the button/key function. Read your keyboard owner's manual.

For wireless, you will need to know how to select the right input source on your TV [wireless, bluetooth?]. You may then have to tell your laptop to activate wireless video output. Read your owner's manual for BOTH devices.

In my limited experience all IBM compatible computers and that is nearly all of them, work in just about the same way. Faced with your problem I would begin by getting into the bios and changing the boot order.
Access the bios during the start of the startup as directed in one of the first few screens - it all happens so fast the computer might have to be restarted several times by pressing the Alt, Ctrl and Del buttons together. Access the bios by pressing the Del, F8 or whatever at the critical time.

Once into the bios go to the page dealing with the boot order and rearrange them so the dvd/cd drive is first in the order and then save the change and exit; then put the Windows system disc in the drive and close the drawer and very quickly restart the computer.

If all is good an onscreen message should appear, Boot from disc? or similar...

you will need to open the laptop to fix this..

inside in laptop is a small c-mos battery, this needs needs to disconnected for about 10 minutes with the main battery disconnected and not plugged in.

replace the battery and the back of the laptop, and boot it up.

after unplugging the battery and mains press power button to release any power left in the system then take the battery out or replace, but this has worked for me 100%

Try changing the resolution while display 2 is plugged in and active. You can also try changing Display 1 resolution (even if its your main screen)
