Hi,
Laptop keyboards can differ with the function keys and are set out different depending on make and model.
If you take a look at the F4 and F8 keys, is there any symbols (in blue) on them? If there is post back here with a description of the symbols, If there is no blue symbols on the keys then they will do nothing and there is nothing to worry about.


Regards.

I can't get my laptop to appear on the Hitachi CPRS55 projector


Hello.

Look at your laptop keys and be certain that Fn + F8 is the right combination. Could be Fn + F4, depending on your laptop.

If the key combination is OK, your VGA cable (from the projector to the laptop) could be faulty.

Hope this helps.

I have an hp ze2000. I hooked it up to an external monitor. When I unhooked it and restarted it my laptop screen now stays blank. Who knows the answer to this?


I think you have to reset through setup F12 or is it F8 restart and push one or the other, then locate menu for screen click to enable.

Haven't come across this before. Best I can suggest?

Which function key allows to switch to tv


Hi there,
You need to press hold the FN key and press the F4 function key once which toggles the display to the External Display source like the television connected along with the LCD of the Notebook.
If the FN and F4 key combination is pressed again, the display will dissappear from the LCD of the Notebook and remain only on the external source.
If the FN and F4 key combination is pressed third time, the display will be back on the LCD of the Notebook and will not remain on the External display source.
Here are these details in other way :
First time pressing FN + F4    ---> Display on LCD and External display
Second time pressing FN + F4 ---> Display not on LCD but on the External Display
Third time pressing FN + F4 ---> Display back on the LCD and not available on External Display (Normal position).
Below are the details of what the Function keys in your DV1000 Notebook work :
fn + f1 Opens Help and Support Center fn + f2 Opens print options window fn + f3 Opens default Internet browser fn + f4 Switches the image among displays fn + f5 Initiates Standby fn + f6 Initiates QuickLock fn + f7 Decreases screen brightness fn + f8 Increases screen brightness fn + f9 Plays, pauses, or resumes an audio CD or DVD fn + f10 Stops an audio CD or DVD fn + f11 Plays the previous track or chapter on an audio CD or DVD fn + f12 Plays the next track or chapter on an audio CD or DVD fn + esc Displays system information.* (*To clear the system information display, press esc.)
Hope this helps...
