Some newer macs already do this, but an internal webcam, properly calibrated, may be used to set brightness correctly. Users may need to manually calibrate for readability.

'Sleep' and 'hibernate' go so much better together, and they are both quite descriptive words. We all know what sleep and hibernation are, and the difference between them.

Sleep rules based on system metrics can be tricky for servers in certain situations, such as where background network traffic or baseline CPU usage exceeds a nebulously-defined threshold. How much traffic? What percentage constitutes an 'idle' CPU (especially on older gear, where CPU is limited, or newer gear, where network services consume little)?

To properly fix this situation, network services could be extended through plugin/module functionality to, if configured to do so, notify the system that their logic, however internally defined, has completed the processing of an operation.

This can be accomplished via a simple interprocess call to a sleep or power management daemon. Each service need only add a bit of code based on what it considers activity.

With the system receiving last activity information from popular services, it can then apply its own time-based logic to determine when to enter a sleep state. This avoids the need for kludges attempting to define 'idle' in a clumsy way not dependent on whether services are truly being used or idling.

Ubuntu developers can, and should analyze the executable codes that are processed in the processor, the graphics card, or any other hardware. Using the codes with least hardware processing to achieve the same result will minimise power usage.

Non-GNU/Linux friendly manufacturers and hardwares are also at fault, but Ubuntu has the advantage of being open-source, this advantage will certainly help in eliminating inefficiency in the software side of things.

Wireless radio consumes a lot of power. It is enabled by default, even if there are no wireless routers in range. If a known wireless network cannot be found, a wired network connection is in use, and the computer is not itself creating a wireless network, it would be nice if the wireless radio was automatically switched off until the wired connection is lost.

Also, if the wireless radio is switched off manually from the network applet, it should remain off after a resume from standby or reboot.

It would be useful to add a small warning window (with a choice oportunity) about this way: "Your laptop battery discharging (less then 20 %). The program which you have chosen is a rather energy intensive. Do you really want to open this program?". And then in case of agreement the system allow the application to work.

It would be nice to add set of user power management settings for different options of power parametres in "Power Management Preferences". For example, "Power saver" or "High performance", which establishes a balance between long battery life and performance. I think it would be good if we can enable or disable these modes and if we can configure these modes. For example, in "Power saver " mode we can choose those functions of the computer or operating system wich we want to disable (for example, wifi, bluetooth, visual effects, etc.) and when we choose the "Power Saver" mode those functions are disabled automatically.

Most CPUs from the past few years support dynamic frequency scaling. The scaling algorithm can be manually selected using the CPU frequency scaling applet for gnome-panel.

I suggest that the algorithm should be set automatically when the power state changes:
1. On AC power, keep the current default (Ondemand).
2. On battery power, set to Conservative (CPU underclocked but will scale up to full speed if sustained CPU-bound process runs)
3. On battery power with low battery, set to Powersave (CPU always fully underclocked)

Perhaps this could be configurable in Power Management preferences.

Automatically asks application to save a work, when battery is in critical level. Also, if this application don't have CPU clock for long period of time, system can automatically turn it off after saving.

It could be a good solution, especially for gamers.

Rather than trying to have the system predict how power-intensive a program might be, design a warning based on the actual power consumption rate. I don't know how power-hungry other laptops are, but mine usually uses about 16-18 W when idle with networking and window effects disabled and the system kept at the lowest CPU frequencies possible, and typicaly around 24 W or so when using slightly power-hungry programs under this circumstance.

Based on this, I'd suggest having a warning that would pop up if the power usage goes above, say, 26 W for over a one minute period. To make it more adaptable to other systems, make it configurable in both time and power value, as well as the percentage at which the warning appears, perhaps even allowing the user to specify multiple triples (time, power value, percentage).

Note: The warning could also provide a "Tips" button, to inform the user of ways that they can reduce power requirements without losing functionality - for instance, lowering the screen's backlight brightness, using CPU frequency scaling, disabling networking, turning off fancy window managers, etc.

Kind of like what you might find on various electrical appliances, have a rating system to let users know how power-intensive certain programs tend to be. Come up with some systematic way of defining this, so that each program being added to the repositories can have a rating on this basis.

This may also encourage programmers to improve the efficiency of their programs, in order to boost their ratings.

An example of why I'm proposing this is the game, included with 10.04 at least, called Lights Off. Despite being a rather simple game, it seems to require quite a bit of power to run, rather disproportionately so in fact.

If you press the control/super/command (if you buy computers from Satan) for, let's say five seconds before you close your laptop, Ubunto won't go into sleep mode but only shut down the screen, and you can keep listening to your audio (or let any other programs keep on running).

This is better because you can choose to keep the computer awake, and not have to go into any settings at all.
