Unable to use energy star functions
Posted on 1997-12-05
Here is my unsolved problem:
I have just changed my monitor and my display card.
My new monitor is energy star compliant.(Hitachi CM630ET) (more precisely it meets the EPA Energy Star VESA DPMS standar and NUTEK specification)
The display Card is a number 9 3D revolution. (PCI bus with 4 Mbytes)
My O.S. is Windows 95 OSR2.
My problem is that I can't access the energy star menu in the screen saver menu. I don't know why but the part concerning the energy star functions is not drawn (it should be beneath the screen saver settings).
I would like that windows switches my monitor to low power mode when I don't use it so What can I do?
We can find on the microsoft site that:
>If your computer can use Energy Star power consumption features, additional
>in Screen Saver properties. To take advantage of these features, both the
>and monitor must meet the Energy Star specifications. Also, the display
driver must support
>the extensions needed to control the monitor. Several hardware providers
>monitors designed to support the Energy Star goals.
I tryed to change the settings in the bios ( power management off, on - Video Off method DPMS, Blank screen, V/HSYN+Blank) or in Windows (I changed the monitor selection, the drivers of the diplay card, I checked off that the monitor is energy star compliant)
But I did not get anything.
So, I installed a new version of windows (on another disk).
On this new version, I can access the energy star box. (whereas I could not on the old one !!!)
Here is a bug of windows !!!
However, when the monitor should switch into low power mode, I get a black screen with a blinking cursor on the topleft corner. The monitor does not go in power saving mode (the led should turn orange).
I tried the experience with 2 different display cards ( Trident SVGA, and Number 9 3D revolution) and got the same result.
I tried also to use my monitor with another PC. The monitor and its Energy star functions were perfectly OK.
As a result I think that the problem could come from my bios.
My Bios is a Award modula Bios v 4.50PG
with the Award plug&play Bios extension v 1.0A
My motherboard is however said to implement the EPA Energy Star PC specification with Deep Green system design (quotation from the user's manual)
If you have already met this kind of problem or any ideas, please let me know.
If I reinstall Windows in my windows directory, will I have to reinstall most software? Can it solve the problem? (I would like to get the Energy Star menu (even if the functions do not work, I hope I will fixe it :-) ).
