Always keep modem -airport plugged in

I am new to the mac world and dsl - wireless technology but happy to now be using Airport Express successfully and most pleased with my switch from teh pc world to mac. In order to conserve energy and to avoid having devices "heat up" unnecessarily, I wonder if I should leave my Hermstedt Xbridge dsl modem and my new Airport express plugged in ALL the time. I only access my mac and therefore the internet for a few hours each day - does anyone have advice about leaving devices plugged in for long periods of non-use? Should I be worried about those pieces getting on the warm side, or is it better to leave them plugged in, in order to avoid re-setting issues? Thanks!

DSL modems, and the Airport Express, are designed to be plugged into power continuously - which is what I and I suspect most other people do. The fact these devices get warm is not something you need to be concerned about.
Certainly, leaving these devices plugged in continuously is convenient. It is largely a matter of personal preference as to whether you want to do yourself and the world a favor with the minor electricity consumption savings you get from not plugging these devices into power when you are not using them.

Is it safe to always keep the PC plugged in after removing the battery pack?

As I'm not going to move my pc for some time, I have removed the battery pack and use the AC power instead.
But I would like to know whether its safe to keep it plugged into the AC 24/7? and does it consume energy or does it damage anything when the pc is switched off?

Will I be able to use my Airport Extreme model A1143 with Xfinity's ARRIS model TG862G/CT wireless modem? If so, how? I want to keep my airport network setting if possible.

Comcast has been hounding me to upgrade to their newer modem in order to obtain maximum bandwidth with changes they've made. They sent me an ARRIS Wi-Fi modem (model TG862G/CT). I was not expecting the modem to have wireless and would prefer using my Airport Extreme (model A1143). I have not attempted to connect the new ARRIS yet. Should I send the ARRIS back or is there an easy way to make use of it while keeping my Airport Extreme fully functional?

Thanks, I will look up "bridge mode" after I log off here. In the mean time, what if I were to simply buy the newest AE—will I still be able to use "bridge mode"? I imagine Comcast would prefer that I use their equipment and will eventually leave me no choice, but until that happens I would prefer to use Apple's AE. What is your expert take on this?
Any AE will be able to do bridge. There is actually very little difference between your ancient AE and the latest AE in terms of functionality.. Apple is minimalist.. so change can be avoided.. no need to add functions that were always missing.
I was thinking the printers are USB?? Is that incorrect.. are they wireless or ethernet? Any native network printer can be simply connected to any router.. it will perhaps be slightly easier in an Apple environment to use them on an apple router but the difference should not be huge..
USB on the other hand is tricky.. you will need to use some router that allows print serving from USB.. that still works fine whether the AE is bridged or in router mode.
Netflix is no problem either.. (assuming you are not trying to bust a geo-block).. the actual netflix login is stored in the TV.. the only security info on the AE is the wireless connection and that can be swapped to any wireless router. No biggie.. geoblocking is a biggie.. tell me if that is the case.
It is really up to you.
1. Do nothing.. let Comcast squark all they like.. they are still providing you a service you can use. They are not going to cut you off if you still keep paying the bills.
2. Change the modem for the new one they sent.. this involves a lot of network modification .. but in view of the age of the current devices.. will have to happen in the near future regardless.
3. Return the modem router and request a pure modem.. to give you as little network impact as possible. You will simply change old modem for new one. However at some point the Gen1 or 2 AE will die.. and the rest of the network will need updating.. you are putting off d-day. Modern wireless routers have come a long way since Gen1 or 2 AE.
Take your pick.. Bob says 3. I say 2 or 3. It makes little difference as at some point the network needs a refresh.

I have a Time Capsule on which I back up 2 MacBooks and on my wife's machine she keeps having Airport Utility popping up all the time with a yellow button flashing on the left and a Red button on the right side with a "1" in the middle of it.

I have a Time Capsule on which I back up 2 MacBooks and on my wife's machine she keeps having Airport Utility popping up all the time with a yellow button flashing on the left and a Red button on the right side with a "1" in the middle of it. Can any one tell me what is wrong. I read where when the yellow light was flashing there was a problem, but I am a novice at this and have no idea where to turn. It seems to be backing up on a regular basis.

On the Mac......
Open up Macintosh HD > Applicatons > Utilities > AirPort Utility
Click on the Time Capsule icon, then click Edit in the small window that appears
Click the Network tab at the top of the next window
Change the setting for Router Mode from the current DHCP and NAT to read Off (Bridge Mode), then click Update at the lower right of the window, and wait a full minute for the Time Capsule to restart to a green light.
Then.....very important
Power off the Time Capsule and your Arris modem/router for a few minutes
Start up the Arris first, and let it run a few minutes by itself
Start up the Time Capsule next the same way
Your network will now be correct, and your printing capabilities will improve.
If Time Machine backups do not occur now, post back and we will tackle that next.

If i keep my computer plugged in all day will that ruin the battery???

Absolutely yes, it will ruin it.
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:

Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

IPhone 4: My IPhone keeps in the "plug-into-iTunes-screen" after trying to update to iOS 5.0. The phone is not showing up as a device in iTunes anymore.

My IPhone doesn't turn on and keeps in the "plug-into-Tunes-screen" after update to new IOs 5.0 yesterday. I also tried to restore it, but it still keeps in the plugin mode. In ITunes the IPhone doesn't show up as a device anymore, but Windows 7 detects it as a camera. I started the problem diagnose via ITunes and it says "iPhone can't be found".I'm using the new version of iTunes.
Can anyone help me?

I have the exact same problem and have just logged on here to see if anyone can help also? My iphone is up and working but itunes won't recognise it as a device... just updated itunes aswell.
Any help would be hugely appreciated!!

Ssvagent.exe does not always disable next-generation Plug-In

Around half the time running the "ssvagent.exe -high -jpisetup -old" in a vbs after the jre-6u22-windows-i586.exe process stops running
the next generation Plug-In option is not disabled.
I have verified that it does not run until after the Java installtion is complete.
Running "ssvagent.exe -high -jpisetup -old" manually right after installing Java will always disable next generation Plug-In.
Any ideas why it won't always run properly from a script?

Hi,
I was wrong in my approach.
My applet was implemented using the "<object>" tag and it seems that it was not the best way to address compatibility issues across all versions of the plug-in and all browsers.
So, I have finally found what I was looking for in this "[Java Rich Internet Applications Development and Deployment|http://download.oracle.com/javase/6/docs/technotes/guides/jweb/index.html]" guide. In this guide, it is recommended to use the "[Deployment Toolkit|http://download.oracle.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit]", based on a Javascript library containing everything needed to deploy your application as an applet or a Java Web Start application.
My application, deployed as an applet, now works like a charm.
I hope pointing on this Deployment Toolkit will also help others...

My iPod mini, 4gb is hard to get serviced obviously because they dont make them anymore
It is as simple to get it serviced as the day you purchased it.
How is it hard to get it serviced?
How long have you had your iPod?
i get maybe 4-5 hours of battery life, maybe even 6 if im lucky
That is not good but it's not "terrible".
If you've had it less than a year, send it back to Apple to replace the battery.
thought that i might buy an attachment type accesorie that i plug into the usb port on my ipod
It's called a dock connector, not a USB port.
i found a product in the online store, that i guess you place the ipod mini on, and it gives you up to 20 or so more hours of time but then it says that you have to have a firewire port or cable?
What is it? The firewire port is on the computer, not the iPod.
If the original battery is going bad, the first thing to do is get that sorted out.

HP Battery, Is It OK to keep the charger plugged in ?

Hi All
This is my first question here and I hope you'll help me
I want to ask if it is OK to keep the charger plugged in the laptop while the battery is full ?
I mean when the battery is 100%, will the energy go directly to the PC or it will go to the battery before ?
This question was solved.

Hi,
Nowadays batteries should be smart enough to stop getting charged when full. I can't see the difference from removing and keeping batteries on AC, some machines sit on docking stations all the times and some machines can be ON/OFF. This is my reply to another post:
