In XP turnning off LCD screen after x min is an option in power options. ( Monitor Standby Mode )

Now in Vista the option is still there but now working properly. My LCD screen is black but the back light is still on.

Anyone have same experience?

Edit: Confirmed Bug with ATI gfx card

Note: i am on a Laptop so i can manually turn off the LCD.

Since i keep my computer on whole night i would like it to turn off the monitor. Normally in XP Power options when i set it to turn off the monitor the actually monitor is actually off. ( No Backlight, just like you switch it off )

But in Vista The backlight is on 24 /7 .

I have the exact same problem, so you are not alone. What graphics card (intel, nvidia, ati) and driver version are you using? I am using a ATI Radeon 9600XT with ATI's Vista RC0 drivers (ati_LH_RC0_32.exe). ATI does have some new drivers out on their website intended for RC1, but I have yet to install them. I am using Vista pre-RC1 Build 5536. Hopefully, we will be able to see if this is an isolated problem affecting just one card manufacturer or driver version, or determine if it is cross platform bug or a bug on Microsofts side.

Hi

Same probs here, two pc, a laptop with mobility 9600 and a desktop with Xpress X200, with Vista drivers (RC1) or with ATI drivers.

Two pc LCD light shutdown well in XP but not in Vista.

I'll try with another PC and another card and try to say you.

I am confused. Are you guys talking about LITERALLY turning off the monitor or putting it in "Stand By mode"? Because in Vista RC1 it turns off my monitor just fine and I didn't even set anything? :huh:

Hi we talk about standby (ex : if you don't touch your pc for 5 min, the screen swith off and when you 'shake' the mouse it wake).

I will try something at my job today, I find a screen saver which put screen in standby mode. I'll say you soon.

I have a Dell 600m with Radeon mobility 9000. I'll have to watch and see if the backlite stays on. Right now I do have the problem where if I close the lid of the laptop the screen does not turn off, however if I set it to hibernate when I close the lid it will do that, so I know it is recognizing that the lid is closed. As of right now I wouldn't blame anything on Microsoft, more that certain drivers are not working correctly or require custom drivers from the laptop manufacture.

I've tried something :

I've installed Standard VGA driver instead of ATI driver (microsoft one or ATI one).

The standby of the screen works correctly with it, when I install ATI drivers again. No standby !

We should all put feedback with ATI Feedback crew for Vista drivers, they may release a new one soon !

    • I think there will be a 27H1 for actual users of 26H1 The 25h2 supports ARM too : Snapdragon X, Snapdragon X Plus and Snapdragon X Elite
    • Poll: Grand Theft Auto VI price predictions, cast your vote by Pulasthi Ariyasinghe After years of waiting, Rockstar will be solidifying the launch date of Grand Theft Auto VI with the launch of pre-orders next week. While the studio has confirmed a date for this occasion, it is yet to attach a price to the highly anticipated game. So let's see what our readers think it will cost at launch. The Grand Theft Auto VI pre-orders will kick off on June 25 for digital and physical editions. Unless some last-minute changes happen, the release date will be November 19, 2026, across Xbox Series X|S and PlayStation 5. Unfortunately, there's still no information about a PC version from the developer or the publisher Take-Two. Now the question becomes, how much will Grand Theft Auto VI cost at launch? The game is predicted by some analysts to be the biggest launch of an entertainment product ever. With the amount of hype that has been built behind it and with ballooning development costs, Take-Two may price this Grand Theft Auto entry differently from other AAA titles. The current price of a AAA game is $69.99. That norm almost rose to $79.99 before calming down. But with such a massive release, Grand Theft Auto VI may be the game that pushes the boundary again. It's also possible that Take-Two keeps the price relatively low to increase the number of players that jump in early and keep them hooked on Grand Theft Auto Online to spend on microtransactions for years to come. Keep in mind that the below poll is asking for a prediction of the standard edition price, not a deluxe or any other special edition that Take-Two will introduce for additional benefits. Also, there is also the chance of the company splitting up the campaign and online portions. If you think that will happen, put your vote on what you think will be the total cost of the two. Poll Poll: How much will Grand Theft Auto VI cost? $59.99 $69.99 $79.99 $89.99 $100 or more Submit Vote If you have a very specific prediction in mind, sound off in the comments below.

    • The Light of Life? We actually do glow till our Death, study finds by Sayan Sen Image by Rafael Rendon via Pexels A study by researchers at the University of Calgary has found that living organisms produce an extremely faint light known as ultraweak photon emission, and that this glow appears to drop significantly after death. The research was published in the Journal of Physical Chemistry in April 2025 and quickly drew widespread attention, leading to more than 200 news stories about the findings. Ultraweak photon emission (or UPE), sometimes called biophoton emission, refers to tiny amounts of light released by living cells as a result of normal biological activity. A photon is the basic particle of light, and researchers say every living system examined so far, including plants and animals, has been found to emit these photons. The glow is far too faint to be seen by the human eye. “I suppose it has a little to do with people being reminded of auras,” says Dr. Christoph Simon, PhD, one of the authors of the study and a professor in the Department of Physics and Astronomy in the Faculty of Science. “It is a fact that living beings glow. It’s a very weak glow, but it’s there and visible with very sensitive cameras.” According to the study, the light involved is extremely weak, ranging from 10 to 1,000 photons per square centimetre per second across a spectral range of 200 to 1,000 nanometres. For comparison, a nanometre is one-billionth of a metre and is commonly used to measure wavelengths of light. Detecting emissions at such low levels requires highly specialized equipment. To study the phenomenon, researchers used electron-multiplying charge-coupled device (EMCCD) and charge-coupled device (CCD) cameras. These imaging systems are designed to detect extremely small amounts of light, including individual photons, while minimizing background noise. The technology allowed researchers to capture signals that would otherwise be impossible to observe. The team worked with the Human Health Therapeutics Research Centre at the National Research Council of Canada (NRC) in Ottawa to examine photon emissions in mice. Researchers took two-hour exposure images of the animals before and after death and compared the results. “We saw that the level of light that they emit – this biophoton glow – is distinctly different between living and dead animals,” says Dr. Daniel Oblak, PhD, an associate professor in Physics and Astronomy and the corresponding author of the study. The images showed a clear decrease in photon emissions after death across the entire body of each mouse. According to the researchers, this provided direct evidence that living and dead tissue produce different levels of ultraweak photon emission. “It’s a very small amount and it’s, of course, very tricky to detect,” Oblak says. The study grew out of discussions between Simon, whose research interests include quantum biology, and Oblak, whose work focuses on detecting light for quantum communication experiments. Quantum biology is a field that explores whether processes described by quantum physics, which studies matter and energy at very small scales, may also play a role in living systems. “Since I work as a quantum physicist on light detection for quantum communication, I thought that experimentally we have a lot of the tools to be able to detect the light,” Oblak explains. The researchers also investigated UPE in plants and found that the light changed in response to stress. When plants were exposed to higher temperatures or physically injured, their photon emissions increased. Chemical treatments also affected the glow. Among the substances tested, the local anesthetic benzocaine produced the strongest emission response when applied to injured plant tissue. These findings suggest that ultraweak photon emission is closely linked to biochemical and metabolic activity inside living organisms. Metabolism refers to the chemical reactions that allow cells and organisms to stay alive and function. Because these reactions change when an organism experiences stress, injury or disease, researchers believe UPE may provide a way to monitor those changes. The researchers stress that the glow is a physical and biological phenomenon, not a metaphysical one. Oblak says more research is needed to understand exactly how the light is produced and what information it may reveal about the condition of living tissue. “We must understand what that is to figure out what’s happening,” he says. “If we can understand how that relates to certain influences on the body – stress, diseases – then that could be used as a diagnostic tool.” The researchers believe the technique could eventually help scientists study health and disease without invasive procedures. Because UPE can be measured without adding dyes, markers or labels, it may offer a way to monitor whether tissue is healthy, damaged or alive. In plants, it could help researchers better understand how organisms respond to injury, heat and other forms of stress. While the work is still in its early stages, the study demonstrates that ultraweak photon emission imaging can provide a non-invasive and label-free way to observe biological activity. Researchers say the approach could become a useful tool for studying vitality, stress responses and other important processes in both animals and plants.
