Is this how a G4 imac's life ends?

Just tried to start up my imac and it would only offer a grey screen with an apple logo. I restarted and reset the PRAM. Same result upon restart. I next restarted with the Install disc to run disc utility but the hard drive could not be seen, only the CD Rom Drive and its contents. Very dire sign. Tried to start off the Apple Pro tools disc. Worse. Could not eject disc. Finally got it out and restarted with Install disc again and was willing to do a clean install but again the hard drive would not come up as an option for the software to install on. Does this mean what I think and the Hard drive is dead? Is there a recognized protocal for honoring and properly burying an i mac?
imac G4 22 inch Mac OS X (10.4.5)

James,
Today was surgery. The operation went extremely well. I was well prepared and followed each image, step by step. Actually many of the connectors one is advised to remove can be left in place to get access to the drive, contrary to the articles I referenced. In fact the only cables removed were the 2 data cables and the ground cable. All others flexed enough that with careful positioning, I worked around disconnecting them saving much time and confusion later. The drive removed easily, the thermal scraping was messy but quick. The only hangup was 1 screw would not line up exactly upon closing up the case. I struggled for 30 minutes before taking the case apart again and lining up that screw first (which was still challenging) and once it was engaged first, the others came together. I am installing the install software as we speak and contrary to my posted title, the imac will begin life anew with a new upgraded drive, new PRAM battery as mrtotes suggested and
a new place on my desktop as I read an earlier post which allows me to also use it as a 20" monitor for my macbook with screen recycler software. (As soon as I figure out what VNC means) So.... I encourage ALL novices like myself to not be intimidated in entering inside the bowels of their mac when necessary (and out of warrantee) and do it yourself, step by step and with the support and advise of the many helpful angels that answer our forum pleas and assist us to rescue our macs from an early resting place and to live on into the apple sunset. Thanks again!!

Thanks....

Launch Keychain Access and click on Login in the left hand pane and then on Passwords. Next do search for Apple in the search field at the top and click on Apple ID Authenicication in the list that comes up. That will give you the ID no. and password.

How to increase the battery life of your N series ...

What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
Hope this helps.

no keffa it is a cop out from nokia
its not unfai as its a premium device with a premium price
the n95 battery is atrocious
dont change the post content as the title is 'How to increase the battery life of your N series device'
your talking about nokia phones specifically
the networks are not to blame
they do not make the handsets : Nokia do !!!!!!!!!!
I'm going to choose my words carefully here...
I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

How to disable iMac screen and not to put it into sleep?!!!

I would like to play a movie on my iMac but to watch it on my LCD TV. How to disable iMac screen and not to put it into sleep. PLS have in mind that ctrl+shift+ eject does not work, it makes my iMac screen go black as well as the tv screen.So far, i have red many articles concerning this subject, but no one seems to have the right answer. I simply can´t believe that apple did not think of it, as it is nothing new ....
Thanks

My brother has eight cats, so your not along. Fortunetly his go outside.
I have been talking to the people over at macforums and they had some good thoughts. One guy suggested going analog and soldering in a rocker switch on the cable connecting a hub to the computer, turn off switch turns off keyboard and mouse.
I was prepared to try that but a great idea came along. Arch, you might be interested in this too. Buy a cheap (found one locally for $20) usb kvm switch that takes one usb keyboard and mouse and connects it to two pcs/macs and only connect one of the outs to my system. There is a button to switch between the two, so when I want to disable the keyboard and mouse, I just switch it to pc2, which is not connected to anything.
Cheap and easy solution. I wish I could of figured out how to do this with software, since there would be no money if it was freeware, but I guess you cant win them all.
Thanks everyone for chiming in!

How does the iMac DC 1.83 compare to the iMac G5 2.1?
In real world speed.
In real world features. ie: video frame rate, etc...
Any REAL hardware problems pop up yet.
Things like that.
I an most likely to get one soon, and would like to know.
Thanks
-Apple //GS

Thank you for taking the time to reply. I hope that others reply also so we can see how this new computer is next to the two G5 versions it is replacing in a real world way.
I am happy that the DC 1.83 is no sloth when going toe to toe with the G5 version.
Did you port over your software from the older system, and run the programs to see how things ran, or freash install them all?
Again, thanks

Is this how this works?

Hey, I'm new to mac and am going to be installing my mac tomarow. I've been researching. Is this how it works in a nutshell?
1.Download bootcamp
2.Run Assistant
3.Run bootcamp & burn driver disc
4. Then partition (this is where it gets tricky)
I heard if I don't do like an 25 GB fat32 File system partition, OS X won't be able to write to the windows folders from within OS X. And it will be forced to format in NTFS.
So if I do 25 GB and format it with fat32 it shouldn't give me an problem? I'll have an nice XP dual boot machine?
5. Eject windows install disc and insert mac drivers disc
I guess OS X will remain default if you don't press Option on boot?
Is this how it works?
I'm working with the new imac 24".

Hi and welcome to Discussions,
first of, there is a separate BootCamp Forum for all questions related to it.
Follow this link: http://www.apple.com/macosx/bootcamp/
Near the bottom of it, you will find a link to the BootCamp Setup Guide. Print it out and follow it to the letter.
FAT32-partitions can be up to 32GB in size.
After the installation of Windows the Windows partition is usually set as default startup.
You can change this in OSX - System Preferences - Startup Volume.
Good Luck

How to override iMac password?

how to override iMac password?

This discussion is for computer built before 2006. The same solution probably applies to newer computers.
You can change the password on an account. ( Do you know Unix. You are in a Unix single user console. ) The setup commands you need should be listed on the screen. For Mac OS 10.4.11, the commands are:
# Type the follow two instructions to access the startup disk in read/write.
# check out the filesystem.
# ( in case of partial success repeat this command until errors go away. )
/sbin/fsck -fy
# Gain read / write access to your startup drive
/sbin/mount -uw /
->Start up some utility processes that are needed.
sh /etc/rc
->You will probably need to press the return key once the system stops typing.
->To find out the users on the system type, use the ls command. The l is a lower case L:
ls /Users
->One of these accounts will be the administrator.
->Pick one of the users which I'll call a-user-name and type it in this command:
passwd a-user-name
->and enter the new user password. You need six characters.
->You will need to enter your password twice. Your typing will not show up on the screen just
-> press enter when you complete the typing.
->For cryptic information on these commands try:
man ls
man passwd
The root account isn't enabled by default. I am not sure if changing the password on root will enable it.

How to improve the battery life after upgrading 3gs to ios5, how to improve the battery life after upgrading 3gs to ios5

how to improve the batter life 3gs phone on ios5 os

Also you may want to check a few things if you have location service turned on for Weather app, cuz every time you check your notification center, it will always check your location for the current update on the weather. If you are in the same location the entire time, you really don't need that on. Also while you are on the location service setting, check some of the apps that uses location service and if you don't use it, then turn it off while you are in there. Also maybe turn them all off and then turn on one at a time and find the culprit.
If it's not your location service, it could be that one your apps is running in the background. Double click home button, this will bring up the recently used tray, hold one of the app for 3 seconds until the - button comes out, then close all the apps. Or just do a hard reset of your iphone by holding the power button and the home button at the same time for 10-15 seconds until the apple logo appears.
Anything that will require to data connection will use battery. If you have wi-fi at home, then I suggest you keep it on wi-fi because your iphone will last longer if it's on wi-fi then on battery.
If none of the above suggestion worked, then I suggest you try restoring your phone and set it up as new and see what happens. Just make sure you have a separate back up for your contacts.

How can my Imac be backup aware ?

Hi,
The computer's activity, as defined by the system's idletime, is only related to mouse move and pressing keys on the keyboard.
While all computer's activity are not really activity to be monitored, executing a backup is an activity that is important to monitor before putting the computer to sleep.
How can my iMac be backup aware (with any backup software) ?
Thanks in advance.

Hi A Brody,
I want my computer to prevent of going to sleep when executing any backup application (Retrospect, Backup, etc ... I thought that there was a way for the OS to be aware if such processes were running. I think that the OS should consider more than mouse moves and key pressing on the keyboard when defining computer activity.
I wrote an Apple Script handler to monitor if certain applications are running. I run into difficulties because managing the CPU's activity by script is not simple (or possible) for applications like Retrospect that are running as Root.
So I thought that some of you would have found a more trivial way of dealing with this also trivial problem ...
Thanks for reading.

How to unlock imac keyboard

hello. I am going through old posts to try solve my problem, this one was the closest to my problem. I am having trouble with my wireless keyboard. It has new batteries, it has power but NON of the keys are working, volume, cap lock….

How do you save battery life by closing programs under i0S7?

How do you save battery life by closing programs under 0S7? You used to click the home button twice, but now, since the update of 0S7, this feature seems to be gone.

click the home button twice, when you see the apps line up on the page, swipe the ones you want to close up and off the page. Scroll to access more apps, tap the home button once to exit the mode
For battery issues, look in the notifications. iOS7 defaults a lot on that you may not need. Also look to the background updating of apps. That can drain battery too.

Is this how a G4 imac's life ends?
