Is the Power Schedule Harmful?

I have noticed an abundance of power issues since this 10.5.5 update. I am fortunately not one of those (not yet at least), however it did raise a question to me. I would like to begin using the auto start up to conserve energy... ya know "be green." So at night I'd shut down and in the AM it will boot up.
My question:
Is this process of powering on/off daily bad for the power supply, HDD, or any other hardware component of my PowerPC? I feel leaving the machine on does less harm than starting it up everyday.
Any other insight would be great!
Thanks everyone,
J3

J3,
Shutting down and restarting does no harm, and doesn't increase the "wear and tear" on your computer. Not at all.
Really, the only thing is does do is flush the contents of RAM, thereby causing the "Inactive" cache to be re-populated with code and data as you launch applications, post-restart. In other words, your computer will not immediately respond as quickly as it would if it were just put to sleep, as far as the launching of applications is concerned.

Is it harmful to leave wall charger left on the power sour

Hi all,
does it damage the charger or reduce its life in anyway if you leave it plugged to the power source after you disconnect the zen micro and take it with you? Basically, is it harmful for the charger if you leave it plugged to the power source all the time, while charging and not charging?
TIA

So are you saying that even though when the micro is fully charged it shuts down it is still bad to leave it plugged into wall?
It still uses some electricity. It depends if you define this as bad.
As mentioned, I think we all have some responsibility to try and save energy.
Also, some batteries recommend that you exhaust them before recharging? Is this the case with the lithium batts in the micro?
No. It's better to top-up the battery rather than charge from flat. It's particularly bad to leave a player discharged for several weeks, and you may well end up damaging the battery beyond repair.
For some devices it's a good idea to do a complete drain and recharge every 20 to 30 or so charges, as this keeps the battery indicator "educated" and accurate. I've never seen anyone say for sure whether this is the case with the Creative players.

Why can't I shut down my MacBook unless I hold down the power key?

Hi all,
I have had this problem my MacBook Pro using both Leopard and Jaguar. It is a problem when I shut down using either the drop down menu or by the power key menu. It appears to shut down but when I close the lid the "sleep" light comes on and is steady. It isn't actually shutting down because if I don't have the power charger plugged in it will run out of charge.
So, to shut down, I hold the power key down for about 10 seconds.
If it does fall asleep I am unable to awaken it (the sleep light is steady) and have to go through the holding down the power key procedure to shut it down and then use the power key to start it back up.
Am I damaging it by doing this? I have tried the trouble shooting options as described in the manual. I had this problem before and one day it just wouldn't turn on and I had the hard drive replaced.
Thank-you very much for any help!

I have found a solution on another thread that seems to have solved the problem for me. That is, I haven't experienced since, either the double password prompt at wake from sleep or the issue of not being able to shutdown.
The solution requires deleting a preference file that apparently carried over from Tiger in the upgrade to Leopard and which is causing all the problems described. Preference files or .plist files hold configuration preferences and settings generally defined by the user for a particular operating system function. Deleting one of these files will result in the system recreating it on reboot with all settings set to default values, this is a simple way of fixing an incompatible/corrupt preference file.

Can I use the power charger(85W T Connector) with MBP(17 inch 2010 mid)?

Hi I have a MBP (17 inch 2010 mid). It uses a 85W L Connector. But today, it is not working anymore. And I found a older charger 85W T Connector is work with it. But I want to make sure it will not break my batter when a long time usage. Does anyone know it?
Thanks in advance.
TO APPLE GUYS,
Why the material of your cable has so bad quality? It seem easy to aging. Not only the Power charger, also with your earphone cable and other USB cable.

Thanks. It can work. But the Apple serivce guys told me it make harm my battery. I don't know why. So I want to make sure at here.
I just wish the apple guys could read it in their free time.

Will using 45 W power adapter harm my PowerBook G4?

Hi!
Since my round charger plug was ruined for my PowerBook G4 (1.5 Hz, 15") I'm using an iBook charger. This charger is only 45W, but since I live in Bolivia, it will take some time to buy a new 65W charger.
My question is: Will using a 45W harm the PB G4 computer or the battery in any way? The voltage is of course also less than on the original charger. I have tried charging and everything seemed to work just fine. But I would really like to know if there are long term negative effects?

I've answered this many times before based on what other say. It's not good to use the 45W adapter on the 15-inch and 17-inch models because it does not get enough power. It can harm the computer, so I've heard.
(Coming from someone who is currently using his 15-inch, me!, while connected to the 45W adapter of my 12-inch one here at my desk!).
It also takes longer to charge the battery.
On the other end, the 65W AC adapter won't harm the 12-inch PowerBooks because the machine will only draw the power it needs.
I think this is why using the 45W adapter with the 15 and 17-inch PowerBooks is not good because it will be "looking" for more power that it DOES need, but it won't get it, putting "strain" on the unit, battery, etc.

Peak Power Scheduler does not save

I have a T420 and Power Manager 6.55 installed.
Because my notebook is almost always working on the dockstation, it keeps charging all the time.
Not good.
So I decided to use the Peak Power Scheduler to use the battery at least once per day. But everytime I try to schedule a Peak Power Scheduler (no matter the configured schedule settings), after I close the Power Manager window and open again the schedule disappears.
This does not occur with other schedule options (like screen time, power management options, etc.).
Any idea?

It sounds to me that the two power managers are conflicting with each other. Try to make your custom power settings inside of the Lenovo Power Manager.
You can do this by opening the Lenovo Power manager and selecting the power plan tab, directly under the tab is a button that says New. When you select this a new window should open to allow you customize your own power schemes. You will be able to customize the System settings such as: Maximum CPU speed, Display Brightness, Graphics Power plan, also desired Idle timers, events, alarms an other advanced settings. Once created you will see your new power plan listed under the default power plans.
If this does not work, I would then suggest uninstalling the Lenovo Power Manager and utilize Microsoft Power Manager.
Good luck! Let me know if you have any questions
Thank you for being a part of the Lenovo Family,
Catie

If I always have my MB Pro plugged into the power adapter. . . .

If I always have my MB Pro plugged into the power adapter, will my battery still wear out as it would if I were depleting and recharging it daily?
I tend to find a power outlet anywhere that I go in order to run my MB Pro on the adapter rather than using battery power. It's a habit that formed while using my 6 year old Powerbook G4 with about 5 minutes of battery life per full charge.
I understand that it shouldn't wear out to the same extent as running the battery down constantly, but is there still a significant effect?
Does the adapter bypass a full battery and power the computer directly?
I feel like an idiot asking this question, but I am really curious.
Thanks in advance for your responses.

Does turning off your MacBook by holding the power button hurt your MacBook

Almost whenever I exit out of War Craft 3: The Frozen Throne my Mac Book freezes up, as a result I frequently turn off my Mac Book by holding down the power button- Does this hurt my Mac Book?

There is most definitely a chance that you can cause stability problems (although, it is somewhat less likely that you would cause any harm to the hardware). The likelihood of you causing problems increases directly with how often you shut down this way. You should be seeking a solution to the issue you are having with WC3. As Johathan mentioned, OS X does quite a bit in it's shutdown process. Bypassing that can cause anything from basic data corruption, to stability issues, to a non-bootable system depending on what the machine is in the middle of doing when you force it to shut down. In general, worst case scenario is that you would need to re-install OS X to fix things up. It's really not worth taking a chance on your systems stability for the sake of a game. I would say that you really should try to track down a solution to the problem you are having with the game.

My iTunes Library is having trouble with a NAS on power schedule

Hey everybody,
This problem is going to be difficult to translate into words.. here goes..
I have a mac, a NAS box, and Apple TV. Everything is hardwired wired to a gigabit LAN.
I have itunes on my mac, with itunes manageing my content on the macs internal HDD (so I can drag and drop music into itunes and itunes sorts it out by its self, also so I can just listen to music whenever).
The tricky part is... I have a NAS box with all my movies (music is local on my mac) that is on a power saving schedule. All of this content has gone though iFlicks (this program rocks!) and is in itunes format. While holing "option" I drag and drop my movie content into itunes. Allowing this content to stay in its current location BUT being added to my itunes library AND still letting itunes do its automatic thing when I drag and drop to add music.
The reason the NAS is on power saving is I work during the day and only watch content at night so why not save the very little amount of power it would use and not leave the HDD spinning all day everyday.
Now this where everything turns bad. Its not uncommon for me to get up early and listen to music or come home for lunch and fire on some tunes. It seems that when the NAS is off and I open itunes to play some music somehow itunes looks for the movies in its library, which it cant find because the NAS is off. Soooo itunes puts a little "!" next to the movie it cant find, and progresses through the movie collection making all of my content unavaliable through my apple tv when I do sit down to watch something regardless of the NAS now being on and the content definatly being there.
The solution I have found to this problem is to select all of my movies and tv shows delete them and then re-add them as I have explained (takes about 15mins to add everything, this is only with a small 3% used of my 6TB avaliable)
Am I missing a tick box for itunes to recheck that the content it didnt find is definatly not there? Or is there some smart work around? Whats the go?
Hopefully this kind of made sense!
Thanks in advance.

All of a sudden even using the power adapter its only at 57% after 8 hours

I have my powerbook 1.67ghz, its plugged in and i have a couple of adapters so i dont think it is the power adapter.
it has been plugged in and only records 57% power. What does anyone think? it fluctuates between GREEN and AMBER light on the power adapter.
On the back of the computer itself i see some green lights but i dont know what they mean.

Hi, Scott.
yes i am using the 65 watt power adapter...
Not when you ran System Profiler and got the results you quoted above, you weren't — at least not if System Profiler can be believed. Set the 50W adapter aside and don't use it with the Powerbook. If your alleged 65W adapter is identified by SP as a 50W adapter, it needs to be replaced with a proper one.
If you "really never use it unplugged," that may explain why your Powerbook is misbehaving. Powerbook batteries want to be used. If you don't completely discharge and recharge your battery every two to four weeks, its charge-level calibration will become very inaccurate, and it may lose capacity faster than it should.
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1490
If the plug on the 65W adapter fits your iBook (i.e., if it's an iBook G4 rather than a G3), test the 65W adapter to make sure it charges the iBook battery properly. (This will do neither the adapter nor the iBook any harm.) If it does, it's almost certainly not at fault. The other three components of the Powerbook's charging system are the battery, the logic board, and the DC-in/Sound card. Plug the 65W adapter into a wall socket that you know is reliable and not switched. Reset your Powerbook's Power Management Unit, following the instructions in this article for your particular model. Connect the adapter to the Powerbook and let it charge for twelve hours without turning it on. Post back to let us know the results.
Other questions:
How old is your battery?
Was this battery supplied to you under Apple's replacement program for original PB batteries within a certain serial-number range? Many of the replacement batteries issued under that program seem to have been defective. They lose capacity very rapidly and prematurely (which yours hasn't done) and/or they refuse to charge even when they appear to be in good health (which yours may be doing). If your battery was supplied under the replacement program, it falls under greater suspicion.

I need to extend the power/thunderbolt connection to my airmac

i need to extend the power and thunderbolt cables to my airmac

The battery stops charging when it reaches 100%, so there is no harm you can do. In fact, it's better to use your MacBook Pro plugged most of the time (but don't forget to use the battery daily).

Possible to turn on a macbook without the power button?

Basically, the power button on a macbook is connected to the keyboard and the mouse pad, and the connector is now broken. I managed to use the hard drive in a mates laptop and schedule it to turn on at a specific time but im guessing the clock might not be completely accurate so i might have to wait a while. Is it at all possible to power up one of these machines without using the power button?
Thanks

To wake up your MacBook via an ethernet connection, you could probably adapt what is explained here (he page also list utilities that can be used on OSX and Windows to send the so-called "magic packet" to a computer):

What's the power Adapter for Macbook pro 13inch Mid 2012 with core i-7, 2.9ghz, 8Gb ram?
AFAIK it should be a 60wat Megasafe power adapter.
But mine shipped with a 45Watt Megasafe. I got it as a Gift from my friend.
Thanks in Advance.

This should be my Adapter right?
Yes.
There is a drawback in addition to taking a longer time to charge up your MBP. In unusual instances when using your MBP with power adapter attached, and running a very heavy load on the CPU/GPU, the MBP will require additional electrical resources in addition to what the power adapter can provide. It will then draw upon the battery. What this means is that using a 45 watt adapter, these conditions are more likely to occur.
Using a 45 watt adapter should not harm your MBP as such.
Ciao.

I had an Intel-iMac fried by lightening. UPS, surge protectors but it happened as I was reaching to unplug. Cold now. Could it just be the power supply? Can I replace that myself?

This is the full question since I couldn't get it all in the box.
I have some complex questions regarding an iMac, a Time-Machine backup, and iTunes on an iPod.
I live about halfway up an extinct volcano about 12 miles north of San Jose Costa Rica. Some months ago, we had a thunderstorm and as I reached to unplug my computers lightening struck about 50 meters from my house. I had an iMac with a 3-Tb external backup drive, a PC laptop and a laser printer on the same power strip. There was a definite surge and the light brighten and then power was lost for a few minutes.
When power was restored, the PC and the laser printer seemed to work fine but the iMac was cold.
First questions: Is is possible that the power supply was fried and not other essential parts? Would it be worthwhile to replace the power supply? Can I, with limited experience and tools do it or need I take it to a technician? My concern is that if the hard-drive is good, there is personal information on it that I don't want to risk.
Next question: Do I need to replace the hard-drive before taking it for service? How hard is that, can I do it? I have seen videos of the drive replacement on-line.
Those are my iMac questions, now the questions about backup restoration.
If there is a saving grace with this it is that the Time-Machine backup seems fine although I have only accessed the data through Finder. I replaced the iMac with a Macbook Air with significantly less mass storage and I can't just move files to the Macbook. My problem is that I have an iTunes library of some 10,000 songs on the backup and until recently on a 160 Gb iPod which was old and it crashed. I have replaced the iPod but have not tried to restore the iTunes library to it because of my confusion about how to do that. Can anyone tell me how I might do that or give me any insight into the process?
Thanks for any help you can give.

Quite possible, but working on iMacs is not easy, & PSU might be prohibitive.
Hopefully the Drive might have info on it, but even pulling that out can be a chore.

Try starting Aperture with the command and option keys held down. You'll get 3 options.
Try each, starting at the top, in order, checking after each to see if it fixes the issue.
