It's a shame that one of the most important issues in the world today is left to non-technical people to bring forth. Yes, the clueless soul who pulled the 40% figure in the scare-o-mecial did so just to impress, but it is possible that some instant-on tv from an earlier time did use a lot of juice while idling, tubes needed a lot of power for stand-by and then more for full on. Today the problem is with the individual power supplies for the lcd, the printer, the cable modem, the router, the digital camera, the ipod, the shaver etc. and when you consider that every watt wasted by the end user means that the powerplant must burn three plus watts worth of fuel, things add up. Yes, i know there are power plants that can reach 60%+ efficiency, but there aren't many of them and that can not be constant day and night. sooo, maybe along with judicial use of apostrophe's, (does the same apply for comma's or parenthese's?) one should consider turning off the power strip and not just the computer at night. You might not save much and you might even push the powerplant to inefficient idling, but it would surely help a lot during the day. and if you really wanted to help, there would be no tv and no computers on during the day, all would be turned on only at night, after the evening peak...

Hi All, I was watching the program "Global warming - what you need to know" on discovery channel yesterday and learned that TV's, and other electronics use almost 40% of their normal wattage even when switched off which came as a real surprise to me and these appliances can result to a whopping more than 1/2 ton of Co2 annually. Well, I do my part by riding my bike to work and taking the public transportation whenever possible which in DC is really well organised. the thing is thats when I thought about the possibility of remotely starting my PC from anywhere. currently i leave it running for the possibility of me having to access it every now and then but would love to hear suggestions as to how to put this together.

I do run SUSE 10.0 and love it.

Thanks in Advance, Arun

Hi Arun, you may want to have a look at: http://en.wikipedia.org/wiki/Wake-on-LAN

Or google for "wake on lan".

Thx, -mw

Did you know that the actual major cause of global warming is the improper use of apostrophe's?

I wonder if that is from the same people who convinced some friends years ago that switching flourescent lights off and on made them use double the electricity so they should be turned off as little as possible.

What we need there is to move as quickly beyond fluorescents with their hideous spectral characteristics to high-output, LEDs for home and office lighting. (Not that I'm agreeing with the silly contention that switching fluorescents increases their power consumption.)

I guess it is the curse of being an engineer; I am going to have to measure the power use of my TV tonight.

That's a special case of the curse of being intelligent and well-informed... 40% is extremely unlikely for a TV, but a reasonable estimate for a clock radio, perhaps. I've heard estimates that the "vampire" devices--those that remain powered when "off" so as to be amenable to remote control--consume about a gigawatt in the U.S. What's the total capacity of the North American power grid? Clearly it's far above the 2.5 GW that would be consistent with the 40% number. Check out http://www.worldchanging.com/archives/004379.html, http://standby.lbl.gov/Data/SummaryChart.html and http://standby.lbl.gov/Data/SummaryTable.html. A priori, I'm inclined to give credence to a study on power consumption by Lawrence Berkeley National Lab.

The green lobbyests know that their 'findings' will never get published in the press if they report actual figures which is why they exaggerate everything 10 fold. They know that if they don't get into the press they'll not get their grants renewed. Buy a KW/h meter and see for yourself if it's a concern.

OT was in the title, not knocking the sentiment, but as people rarely challenge the information they're given lobbyists can make any statement they like without having to qualify it which is what I object to.

I thought the key thing with fluorescent lights was that the turning on significantly reduces the overall life of the neon-tube, and they are therefore best left on instead of switched on/off. Maybe that's no longer correct, or maybe it never was?

There's no neon in a fluorescent lamp. They use mercury vapor to conduct the current that ultimately yields the UV output that the coating on the inside of the tube converts (via the phenomenon of fluorescence) into visible light. In the old days when fluorescent lights took a few seconds to "warm up," that delay was necessary because there was a heater that vaporized enough mercury to get the arc started. I don't know how fast-start fluorescents are different, but I don't think they have the heater. As to the contribution of a start cycle to the lifetime of a fluorescent lamp, I don't know. It could be another thing that is not longer true of contemporary fluorescent lamps.

A fluorescent tube that's turned off draws no power. There will be a brief surge when turned on. So, unless it's being turned off and on repeatedly, there's no way that statement holds. BTW, fluorescent lamps do not use neon. they contain mercury vapour, which emits light in the UV range, which the phosphors coating the tube then convert into visible light. Neon lamps contain neon gas, which emits an orange lights.

You can wake on almost any interrupt, depending on the bios. If that irq is the one coming from the modem (ring?), you got it. Or almost, because the computer must be simply suspended, not powered off.

I think there existed the possibility to wake on ring, and that some BBSs used it. Not very sure about it.

It the computer has a power up pin, it would be possible to use the ring line from the external modem to wake up the computer - but any ring, mind, even for a wrong number. And the power supply would be on full time.

Get a Linksys WRT54G/GS/GL or similar router/firewall listed at http://www.dd-wrt.com/wiki/index.php/DD-WRT_Docu_(EN) and flash them. SSH server and client as well as a WOL client are included. Leave this device and the DSL/cable modem on all the time and put the computer into whatever low power mode its WOL will respond to. There is now a simple method to flash the version 5 and newer Linksys WRT54G's that are based on Vxworks.

Be aware that when (not if) it fails, Linksys won't send you a new one until you return the old one. Check out the forums. So if you're actually using it, you need to buy another while you wait. Or you could start with a different vendor ...

True for any "single point of failure that will not allow me to compute" hardware you own. Sage advice on checking the return policy of any vendor also.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I tried setting up wake on lan yesterday and it didnt work. I might have a very old bios which I might have to find out how to upgrade as the msi website makes it available as an EXE :( . I might also have setup the bios wrong too. Heres what I found in the BIOS I have an Award 6.0PG bios Under the Power Management Setup Sleep State ********** Was in S1(POS) "The S1 state is low power state. In this state, no system context (CPU or chipset ) i s lost and the hardware maintains all system context." I changed it to S3(STR) "The S3 state is a lower power state where the information of system configuration and open applications/files is saved to main memory that remains power while most other hardware components turn off to save energy. The information stored in memory will be used to restore the system when an ?wake up? event occurs." Soft-Off by RBTN "This item allows you to configure the power button as a normal power ON/ OFF button or a soft-off button." *************** Was in Instant off. "The power button funct ions as a normal power ON/OFF button." Changed it to "Delay 4 sec". "Pressing the power button for more than 4 seconds will l place the system in a very low power usage state (Soft-Off state), with only enough circuitry receiving power to detect power button activity or Wake Up On LAN/Ring activity." This is what I did after that: I ran the wakeonlan from my laptop as mentioned in section 3 of this article http://gsd.di.uminho.pt/jpo/software/wakeonlan/mini-howto/wol-mini-howto-2.h... Ethereal showed me that the packets were being sent but the computer did not wake up. The ethernet light on that computer is glowing which probably means the device is up and listening. My question is There is an IRQ/Event activity detect section under power management which has 3 items USB Resume from S3/S4 which is enabled Wake by PCI card which is enabled IRQ activity monitoring which inturn has all these IRQ's from 0 to 16 some of the them listed as COM, Floppy, mouse etc but no ethernet PCI. all of them are enabled except for IRQ8 RTC Alarm. I dont know too much about these thats why I didnt change the setting. Is this something I have to play with too? Thanks for all your help guys, really appreciate it. Arun Carlos E. R. wrote:

Um, pardon me if this is a dumb question... Don't WOL (wake-on-LAN) capable network cards have a little dinky jumper from the network card to the motherboard? A two- or three-pin? The ones they ship with 3Com cards use yellow wire.

Do you have a WOL connector on the NIC? Is it connected?
