I'm running Vista Business, M200 Vista Drivers i

[AlexOsadzinski]

I'm running Vista Business, M200 Vista Drivers including the 97.52 display driver. Bios is the latest version 1.80. Everything works fine, except that the backlight doesn't go out when the display blanks as part of the power scheme: the screen goes blank, but I can see that the backlight stays on, and thus continues to suck battery power. I'm sure that it's some setting that I have wrong and can't find. Anyone else have this problem and, better still, a solution?

Thanks! Alex.

The backlight should be controlled by the Toshiba Power utility, not the display utility. Is the Power Utility loaded, and if so, what are it's settings?

Hmmm. I may not have the Power Utility installed. I installed all of the M200 Vista drivers from the recent thread of that title, and now my power settings include a "TOSHIBA Power Saver Settings V8.01.02" item under advanced power settings. That only has a "Cooling Method" setting.

This is a clean Vista install, using ONLY the M200 Vista drivers. Is there a separate power utility that I should install (perhaps a Windows XP version)?

Thanks again, Alex.

I didn't get the Toshiba Power Management Utility either when I installed (all of) Toshibas Vista recommended packages.

Perhaps the power management is thought by Toshiba best left to Vista ?

But then, perhaps not ?

But, wthor, the key question (to me, anyway) is: does your backlight go off when the screen blanks?

[wthor]

(I have an M4, which is approx. as "old" as the M200, but not quite the same hardware, which makes my answer partially non-relevant but the Vista support is mostly the same) yes, my backlight does go off.

Mine does this too...[xx(]

I had the same problem on my M200 with any of the newer drivers.
I'm currently using the rather old 46.44 drivers for windows XP.
They don't allow you to run aero glass but the allow the screen to go blank and also I have no issues with the screen not coming back on on returning from standby.

46.44????? Where did you even get drivers that old? Can you run at 1400x1050 still?

[jnjroach]

blink182prj...46.44 are the XP drivers the M200 shipped with...

The backlight issue is a known issue with Vista drivers. There are currently no ways to actually fix this, as far as I know.
