LCD Smartie 5.4 and System Standby

bobwadd · Post by **bobwadd** » March 21st, 2007, 5:08 am

Hi, I am currently running LCD Smartie 5.3 under WinXP Pro with no issues. I upgraded to 5.4 and everything worked great except when coming out of system standby. The CrystalFontz display initially wakes up, but then turns back off. Display is connected through a USB port with the latest USB drivers and the latest CrystalFontz LCD drivers. I have since rolled back to version 5.3 and the problem went away. Any suggestions?

Thanks, Bob

See if this helps. The driver was getting incorrectly disposed, which would cause the COM/LPT port to be "occupied" when the system comes back up.

If it works let me know....

Mike,

Display now takes longer to "wake up" than it did with version 5.3. It also flashes a couple of times. Just letting you know, not a problem for me.
All in all, you solved the problem. Great work!!!

Thanks for a awesome program, Bob

PS - While I have your attention, is it possible for LCDSmartie to monitor the sleep state of the system display? I would like to create an action based on this.

It would probably be best to do this in a plugin.

By sleep state of the system display, do you mean whether the monitor is in screen saver mode or sleep mode?

Yeah Mike, that's exactly what I mean. I could have worded that a little better.

My display has white LEDs and as you know, they have a relatively short life span. I posted a request for a plugin a couple of months ago with no takers.

Thanks for the quick response, Bob

Only thing I could find was how to detect screen saver or not. I'm not sure if that gets it for you. I also found how to figure out if power saving mode is enabled, but not the power saving state the machine is in.

In other words, I can detect when the screen saver kicks in, but not when the screen goes dark when Windows goes into low power mode.

I think an action based on screen saver activation would suit my needs. Can you also detect when the screen saver stops?

Mike, are you saying that you might write a plugin to detect the screen saver state?
