I've been to many PowerPoint presentations over the years. And though most people know that they need to put their computer in "presentation mode" before their talk, almost everybody forgets. So in the middle of the high-power presentation, invariably with bigwigs in the room, the screen goes blank,
and out pop silly flying toasters or (much) worse. The speaker must stop mid-sentence, and frantically scramble to wake the laptop. It might then take the presenter a minute or two to regain his composure and continue where he left off.
This all to common scene could be largely prevented if there was a prominently placed button (or function key) that disables the screensaver. This button should also turn on a small indicator light, so you don't forget to enable the sceensaver again, when the presentation is over.
For further convenience, perhaps the laptop can also have an option that allows PowerPoint to automatically disable the sceensaver during presentations.

Is the closest thing to screenburn, and isn't permanent. [mitxela, Jun 16 2009]

[Imho], i think this can already be done via the O/S. |

I'm confused... doesn't the presenter move or click the mouse to
change each slide? That usually resets the screensaver
countdown. I'm not saying this isn't a valid problem, but I've
never experienced it. |

The worst is where corporate policy mandates non-disableable screensavers on ALL computers, with a <1 min timeout, and mandatory password entry to unlock.... |

(not naming any large paranoid Japanese multinationals that I used to work for...) |

What happens when the careless presenter forgets what the
indicator light is for (there are already so many) and forgets to
turn the screensaver back on? Then the computer gets ruined by
phosphor burn-in and the company's out one computer.
Besides, if the settings are password-protected by an
administrator, how does the switch override that? What does
that switch do that keeps the screen active? Does it simply keep
the cursor in constant motion? What? You need to explain this a
little better. Personally, I think a manual timer (not to exceed one
hour without screen activity) would be best. But if the company
saw fit to lock down the screensaveer setting like that, why
would they undermine their own efforts with a switch that
bypasses them? It makes about as much sense as a screen door
on a submarine. |

Screensavers are completely pointless on laptops - LCD screens do not get screenburn. Neither do projector screens. |
|
| |
But this idea is easily doable - just like there are buttons on laptops which change volume control, etc, which just sends a command to the OS. |
|

The Macintosh screen savers I used in the 1990's were all configurable to have a "never screensave" corner and a "screensave now (after about 2 seconds)" corner. Just park the mouse in the appropriate corner to achieve the desired functionality. |

How about a screen saver that bounces trivia questions related to the presentation around the screen? That way, if the presenter is spending too long on each slide (violating a cardinal rule of presentation design), at least the audience can test their comprehension rather than diverting their attention elsewhere. |
