I have an old G4 mirror-door that I use as my PVR. It's stuffed with 4 big drives to record media, but it runs all day and sucks tons of power. Plus, it heats up the cabinet like an oven. Is there a piece of software etc. that can help the mac better manage its power consumption? I don't like using the OS X drive sleep option because the drives always go to sleep just when you need them..

View 5 Replies View RelatedI have a question about the Dual-Proc MacPro's power management:
If you are only running one or two applications, using one or two cores, is the power management smart enough to put one of the processors to sleep, or into a low-power mode?
Maybe someone can help me understand this a bit better. I have a MBP with a 2.16GHz CPU. I think it's about 2.5 years old. It has the ATI x1600 GPU. My dad previously had an iMac G5 2GHz but now has one of the new iMacs at 3.06GHz.When running iStat, I can notice an obvious difference in the CPU temperature. I don't think my MBP runs less than 120 degrees idle, while the iMacs were easily under 100. I haven't seen the new iMac while doing CPU-intensive tasks, but the old iMac never got above 140 if I'm not mistaken.As I'm encoding video on the MBP for a DVD using iDVD, it's getting up to 187 degrees. The CPU is using about 125 percent of my processing power -- 200 percent max if you didn't know. The temperature is the same even when HandBrake gets up to about 190 percent of processing.
View 5 Replies View RelatedWe have about 10 PowerBook G3/400 computers in our school running OS 9.2.2. They haven't been used in a couple of years and now none of them will boot up. No power. I checked Apple's website and found an article called Power Management Unit. It says to hit the reset button, wait 5 seconds and then hit the power button, but it didn't work for any of them. Does anyone have any ideas?

Is there nothing that automatically sets the screen to a certain brightness, turns bluetooth and wi-fi off etc., and then adjusts it back when plugged in to the charger?
Cannot use the external keyboard's USB sockets anymore for mouse or printer. Warning says not enough power, use computer's plug. But there are none left. Tried to adjust power management.
No betterment. Can't boot from DiskWarrior CD anymore.
I am almost 100% that an iMac 27 is my target, (not quite discounted the MP but lack of remote without extra is actually a big factor).I would prefer the internal HDD bays and such forth, but I've had a MP before and as I have some ext FW its not a deal buster. The imac looks stunning, has simplicity and a nice big screen.My only real questions are (with it being on top of the desk); what's the noise and heat like for the i5 and i7 models? I'd like to get thoughts on both.For my uses an i5 has enough oomph, but the i7 would be nice (just speed up those transcodes etc).Is there a huge difference in the power draw on these machines (I have a 1200VA UPS).
View 3 Replies View RelatedJust on a curious thought, anybody's MBPs experiencing heat issues that cause the fans to kick in so much that they power off instantly? And another question, if you do feel heat, where is it the most intense?

Basically Apple wireless keyboard works perfectly in Windows, but the Bluetooth power management kills it after just a few seconds, which is extremely irritating. It works after you've 'woken it up' again though.
I can't find anywhere to change this, and no joy with a forum search / Google.
I just got my first Mac, an iBook G3, 800mhz,.
I love it thus far, but there is one thing... the heat is pretty suprising. It's not exactly "Oh crap!" but it's definatly warmer then my PC laptops..
Is this normal? Should I be worried?
My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.
View 10 Replies View RelatedI have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
View 3 Replies View RelatedI'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.
I have a PowerMac G5 with the first motherboard that is out of order, and another PowerMac
G5 Late 2005
with 2x2.0GHZ
Mounting the powersupply from the 2004 on the 2005 is the powersuply compatible or not?
EDIT: I looked on Mactracker and compared the two:
Max Watts in the first is 604W and 450W on the late 2005.
I want to put a powersuply from a G5 2004 (604W ) on a G5 2005 that had a 450W powersuply is this possible ?
My G4 Powerbook 17" 1.5mhz stays on most of the time. Only thing that really gets any rest is the screen once in a while. For this reason, is it better to just power it off the powersupply and take out the battery? Any harm done in having the battery there and charging for extended periods?

View 2 Replies View RelatedMy mother just had her G4 Mac die on her. She bought it four years ago! She got the last MDD Power Mac G4 with dual 1.42 GHz PowerPC 7455 processors, running on OS 9!
Photoshop, Illustrator, Quark, Flash, Office, GoLive, InDesign, Image ready, Dreamweaver and so on, is the programs she use the most.
She has been quite satisfied thus far with the performance of the G4, until now(DEAD...)
She now considers getting an Mac Mini, with 2,0 Core 2 Duo Processor, 2 GB Ram running on Lepoard with a 160 GB Harddrive.
My question is - Is the Mac Mini powerful enough for the programs that she uses mostly(mentioned above)
Will the Mac Mini be more powerful or equal to the G4?
The Mini has a integrated Intel 950 GPU - Would it be enough to run does programs decently?
I know that the buyers guide suggests not purchasing a mini, but we are short on money, and she needs the computer to do her job as a web designer/art director!
An alternative would be to purchase a refurbed G4 similiar to the one she had before!
I dont know what to advice to her. When money is an factor, and considering that she has been happy with the G4 for the past for years, I just dont know...
Currently it is almost entirely unresponsive. I came to wake it from sleep a few days ago and it refused to wake. It is totally unresponsive to the power button on the Apple Cinema display and when the power button on the front of the tower is used the button lights up blue and then goes out. There is no fan activity or other sign of life. There is no burned oder or evidence of anything charred.It is a dual 1.42 MDD FW800 machine with AGP graphics. Model: M8570So far I have:
-Removed and reseated the graphics card, RAM and other PCI cards.
-Removed battery and let it sit unplugged over night.
-Performed PMU reset. (once)
At this point I have come to believe the power supply needs to be replaced. it is model: 614-0224 (360w). After looking online they are stupidly expensive, from $180 to over $500 each. I will be ordering a new MB (PRAM?) battery (Saft 3.6v LS14250C) and replacing that as well.
Questions:
- Have I missed anything here? Is there any other explanation or method of troubleshooting I should try?
- Is there any cheaper source for the power supplies? Why are they so absurdly expensive? Does anyone here want to give me a sweetheart deal on one?
- Can anyone recommend a source for the LS14250C battery locally in Manhattan? Radioshack has it as an online only item and wants $15 for it.
Yesterday it would not power on, the day before it was working perfectly. I tried switching out the power cord, and also holding down the power on button for a few minutes. Purchased in August 2005 never had a problem. It is 1.8 GHz 20-in integrated flat panel.

View 4 Replies View Relateddoes the older non-iSight iMac G5 have a built in PSU? (no external brick?)
what does the connector on the back of the iMac look like? (or the plug)
thinking about an older iMac G5 (vesa mountable) for a project Im working on
I thought I'd write this brief how-to incase anybody else ever needed the information. I have bought 3 power cords/connectors/adaptors for my iBook in the last three years - crazy, right? I stepped on the tip of the first one by accident, and was unable to bend in back into shape. The second one (a third party version by MacAlley) spontaneously conked on me, the brick stopped worked. And more recently my third, another third party bought cheap off eBay because I was fed up of paying, developed a connection issue somewhere in the wire (it worked fine, then I had to fiddle with the wire to get it to work, then it stopped working). With all these broken connectors sitting around, I figured there must be a way to solder them together and avoid paying another 30$ on eBay and being without a laptop for 2 weeks.
STEP ONE:
Assemble all the broken adaptors you have, asses what works with what.
- I took the brick from the original which was working fine and the tip from the 2nd cord (the one where the brick stopped working)
STEP TWO:
Cut off the tip from both cords, make sure to leave plenty of wire attached to the brick and tip your using.
STEP THREE:
Strip the tips of both wires, there should be two sections; an outside section (wrapped around the inside section) and an inside section. In the original Apple adaptor, the outside section was braided around the inside (which was incased in rubber) along with a yellow insulator. In the second adaptor (MacAlley) the outside was twisted around the separate inside wire.
STEP FOUR:
Clearly seperate the two sections of wire from each, then twist them together. MAKE SURE THEY TWO SECTIONS (INSIDE VS. OUTSIDE) ARE NOT TOUCHING. You don't want to short-circuit your adaptor.
STEP FIVE (optional):
Solder the wires together
STEP SIX:
Tie a knot in the power chord before the connection, to avoid accidental stress on the joint, and cover it all with electrical tape.
So far, its been working fine. But be warned, THERE IS SOME RISK INVOLVED WITH THIS PROCEDURE. My battery is charging fine and the iBook is powered as usual. I'm just waiting for the battery to fully charge to make sure the power adaptor stops charging the battery when its full (don't want a cooked battery!)
G4 733 D/A , 10.4.11. This morning there was a few second power failure according to my wife. Ther G4 shut down from the power failure. I didn't have "restart after power failure" selected in the Energy Saver prefs. I restarted the G4 when zi got home and after I was done with it, selected SLEEP from the menu. The G4 wouldn't respond to sleep. I logged out and tried SLEEP from another user acc't and from the login screen. I then went into the Energy Saver prefs, made sure everything was as I wanted ( 5 min display sleep, 10 min HD sleep, and "put disk to sleep whenever possible". I then rebooted and sleep still wouldn't function.
View 1 Replies View RelatedMy Power Mac (2x2GHz G5, Late 2005 model) is acting strange since a couple of days when I want to start it up. When I press the power button the white light comes on for a short time and goes off again. When I press again and hold the button the white and the red light come on, usually also the startup chime sounds, and then the lights go off again. When I repeat the action the computer eventually starts and boots normally and then works normally. Sometimes it works already the second time, sometimes I have to try more times.
Does anybody here know or have an idea what this might be and wether I can repair it myself?
