Why on some switches have writing ON/OFF, if\nwhen the light's on we already know and when it's off we can't\nread it?

Usually that means that there is something up with the cable modem.\n\nThe first thing is to make sure you cycle the power on the modem every time you switch (between being connected directly to the router, computer 1 or 2). Every time the MAC address changes (for example if you change it from Cable Modem to Router TO Cable Modem to Computer 1) then you need to cycle the power. If you are just unplugging devices behind the router this usually isn't necessary.\n\nNow, any time you reboot the modem wait a minute and reboot the router.\n\nOtherwise, check the lights:\nPower: Should be steady. Blinking usually indicates a hardware failure or that standby is on.\nSend and/or Recieve Light(s): Should be blinking rapidly when plugged in to a device. Slowly or solidly can indicate a problem with your network cable or modem.\nCable: Should be solid. Blinking slowly or off indicates a problem with your cable connection (usually physically) or modem.\nPC/Activity: Should be blinking fast or solid. Blinking slowly or off indicates a problem with the modem, the cable between the two or the device plugged in.\nStandby (if applicable): Should be off. On or blinking indicates that it is in standby mode. Some modems remember this even when power is cycled.\n\nIf all the lights blink in sequence, stay on or stay off the modem is usually shot.\n\nHope this helps!\n\nEDIT: From the manual:\n\n"Light -Turns Off During Startup- If Turns Off During Normal Operation If\nReceive- The receive channel cannot be acquired - The receive channel is lost\nSend - The send channel cannot be acquired - The send channel is lost\nOnline - IP registration is unsuccessful  - The IP registration is lost\nPower - The cable modem is not properly plugged into\nthe power outlet\n -The cable modem is unplugged or is in standby\nmode. Press the Standby button"\n\nAlso:\n"f the solutions listed here do not solve your problem, contact your cable service provider. Before calling your service provider, try one of:\n• Unplugging and plugging in the cable modem power cord to restart the cable modem\n• Pressing the reset button on the rear panel\nRestarting or resetting the cable modem may take 5 to 30 minutes. Your service provider may ask for the status of the front-panel lights as\ndescribed in “Front-Panel Lights and Error Conditions” on page 44.\n\nProblem Possible Solutions\nGreen POWER light is off - Check that the power cord is properly plugged into the electrical outlet and the cable modem.\nCheck that the electrical outlet is working.\n-If the Standby light is on, the Internet connection is off. Press the Standby button to reconnect to the Internet."

You aren't clear about whether the switch is on in both measurements.  If it is, then the voltage will be the same.  If not, then the voltage will be different because of the voltage drop across the internal resistance of the battery.

By touching the lamp you are changing the capacitance of the lamp and a circuit inside the lamp detects the change and turns on the light. \n\nIn order to offset sensitivity to temperature and other objects near the lamp it is designed to be triggered by a sudden change in capacitance - so when you slowly touch it, or tap it with an object with insufficient cpacitance then the circuit does not detect enough of a change to trigger.

If your computer is not working properly when it is switched on, it could be a problem with device drivers, hardware or software. \nDetailed instructions at  http://tinyurl.com/yd34oj

Perhaps we should earn points for correcting spelling mistakes in the question... Thanks to Konqueror's inline spell checking, I don't make mistakes myself any more (cue people jumping to prove me wrong).\n\nOh yeah, and thanks for stealing my electroshock keyboard idea; I've been advocating that one for ages!

well it could be a bug or you may be turning it off improperly

Well,\n\n---->Use a little piece of Scotch tape to hold the switch in place while I inserted the card into the reader. Works perfect now. \n\n-------->To things called WRITE_PROT that lead me to believe that there is a software toggle inside the chip. Here are some lines from one .PDF file I found: CMD28 SET_WRITE_PROT Optional CMD29 CLR_WRITE_PROT Optional CMD30 SEND_WRITE_PROT Optional

A current flows means there is a motion of electrons in a particular direction (not random motion). In a circuit the electrons cannot accumulate at any point. So to have a current one needs a closed circuit. When the switch is open there is no current and thus no light. The elctrons move randomly without any effective direction of motion.

Same as anything..."ON" turns it on, and "OFF" turns it off...I'm guessing.

a lot of outside lights and street lights turn off and on depending on the amount of light around them. maybe your car lights are too bright and this causes the outside lights to turn off. Are you always in your car when this happens? if so, this may be what's going on.

Are they supposed to come on automatically at dusk? Check your manual. If they are supposed to come one automatically, and none of them do, then there must be a short in the wire from the automatic switch or the switch or electric eye component must be dead.

Check all of the switches while your in the room.  You never said we had to leave after we looked once.

The light is to indicate Hard drive activity. It is a meaningless today and you can safely ignore it. On systems I build I don't even bother to plug that in.\n\nBack in the days of DOS it was a usefull part of a computer. If you had HD activity but was not saving something or had no other reason to see HD activity it could mean you had a virus.  Today's multi-tasking OS's are complex beasts and even if your machine is doing nothing the system is writing/deleting cache files, defragmenting, indexing files and a host of other tasks.

Just look inside a flashlight.  Simple circuit with a switch.  Open the switch, no light.  Close the switch (turn on light), you have current flowin'.

This is a perfect question for the section called 'corporations'.\n\nThe answer is 'NO'. Even though you leave the light switch on, the burned out bulb breaks the circuit and uses no electricity.

Here are the steps to do this task-\n\n1.Let's name the bulbs A,B & C & the switches 1,2 & 3.\n\n2.Put the switch #1 ON & leave it for some time.\n\n3.Now put switch #1 OFF & immediately put #2 ON.\n\n4.Quickly, go to the second floor & touch all the bulbs.\n\n5.The hottest bulb which is not glowing is connected to switch #1\n\n6.The glowing bulb is connected to switch #2\n\n7.The bulb which is not glowing is connected to switch #3
