yesterday evening we had a power outage at my house, My G5 power mac was in sleep mode when the power went out. When the power came back on my mac came back on as if it were sleeping. The LED light in the front will stay on but the comp is non responsive. I 've tried holding the power button down for longer than 2 mins and nothing, I've tried unplugging everycord from the power mac and leaving it unplugged all night then this morning plugging everything back in and it still is non responsive, with the LED light still on. I am not hearing any nosie's coming from the power mac. I read on the apple website that it could be the PMU or SMU But I purchased the power mac late 2004 and as from what I read the only way to reset the PMU is to turn off the mac then unplug the mac and leave it unplugged for 2 mins then plugging it back in, If that were the case then leaving it unglugged all night should have reset it. I'm not sure yet as to if the power mac G5 has the SMU reset button or not because I'm at work.
My Friend has a 15" Powerbook (2nd last rev.... 1.67ghz with lo-res screen) and it's been on the fritz lately. It operates completely normal and then it suddenly goes to sleep. When I wake it up it's back to normal just fine. It goes to sleep after about 3 minutes of use.
My PowerBook had a battery problem (dead battery which did not charge anymore). It lost date and time several times while mac was on AC and power cord was removed. Now it has a brand new battery. Since then, Powerbook does not go to sleep mode anymore:
- if it goes to sleep following settings of energy saver prefs, it doesn't wake up anymore, black screen and LED stays on
- if I force it to sleep through the Apple menu, it freezes with a black screen with the following white text: You Mac needs to be restarted by pressing for a few seconds on the power button.
I have tried to reboot with apple-alt-P-R and waited 5 reboot
I have tried sudo pmset -a hibernatemode 0 in the terminal
My roomate as a powerbook g4 1.5ghz, it had been running 10.4.8. The computer will go into sleep mode randomly about every 10-15 seconds. Doesn't matter what program he's using. If he leaves the comp off for a few hours, it wont do it for a while and he can use it. Only thing we've found online is that people had that problem when they had faulty trackpads/trackpad sensors. But we don't think that is the issue we weren't getting an error message as they were in the console when it would occur. We called a local mac shop and they said it'd be 100 bucks to diagnose the problem, and probably it sounded like he would need a new logic board for another 700 + Labour.
A friend at school had the Apple Service Diagnostics 2.5.8 boot disk. He told us to give it a shot rather than paying the 100 bucks to get it "checked out" as it would most likely tell us what, if anything was wrong. We ran it, all hardware and software tests passed w/o any errors. We even tried doing a full format and reinstall of OS X 10.4.1, it got through the install procedure, and it seemed to be working ok for about 30 minutes, then suddenly the problem started again! So I that makes me think its not software related. So far two software "tests" and one full ASD hardware test got us nowhere. He's tried a lot of stuff he found online, but nothing has worked. Such as resetting all the various rams and sensors and PMU.
It wont wake from sleep and after I reboot it, it wont even start. After the chime, the screen stays blank and the fans start roaring high after a few minutes. I brought it to the Genius Bar. They ran diagnostics on it and concluded that the problem is the 3rd party RAM. I then removed the RAM when I got home and it worked for a day. Now, the problem is back. I already reset the the VRAM and the SMU. I'll bring it back today to the Apple Store but I dont know if they will even entertain me this time as they didn't even charge me for running the hardware diagnostics last time.
I put my PowerBook to sleep and instead of going to sleep it locked up half way to sleep. The clock and WiFi settings were reset. What would of caused the WiFi settings to be reset?
i have a powermac g4 that is running fine, but when i click on the apple sign and tell it to go to sleep. It goes into sleep mode and then after that shuts down. Is this normal, I think it might be a setting a have to change but I am unsure because this is my first mac.
I recently bought a second hand Powerbook G4 1.67. It came without a hard drive so i put a new drive in and installed Leopard on it. The problem, before I upgraded it to 10.5.7 sleep mode would work fine but since the upgrade after waking up from sleep only the mouse will work and the rest of the screen is frozen. Anyone else have this problem or know of a fix?
My G4 PowerBook (Aluminium 15" 1.67Ghz, A1104) keeps putting itself to sleep at odd times. This is without a main battery in place, and a dead PRAM battery, both of which I'm waiting to replace.When I wake it up, it tries to power up, HD spins, but then goes back to sleep without even the screen coming on. I can do this like 5 or 6 times, and then eventually it wakes up and stays awake. For a while.or the first time today it wouldn't actually even start up from a total shutdown 2 minutes revious. It was just dead. After about the 6th press of the power button it started up.
I had an iBook, now I have a powerbook. Both have the feature when I shut the computers and they are in sleep mode, the light goes from dim to bright to dim to bright..... It drives me nuts. I have to put my computer in a drawer or cover it up at night. Does anyone know how to turn the light off? or have it be constant? Is there a download that fixes it?
My G4 Rev E PowerBook won't wake from sleep. The battery died and the computer slept, but now when I boot it, it gets to 3.5 progress bars and freezes. I have tried rebooting but I can't seem to get out of the resume from sleep mode.
Any ideas? It doesn't show the grey Apple screen like it does from a fresh boot, just the progress bars that show up when the battery dies.
Last night I put my iBook to sleep and now it won't seem to wake up. The little snoring light thing is maybe half-lit, but it doesn't snore like normal--just one solid, half-way lit light. I've tried force shuttng down (holding down the power button) and force restarting (command-control-power), and neither work. I've also tried the obvious--closing lid (it was open), unplugging it (the battery still has life though).
I can put my iBook G4 to sleep manually, but it will not sleep on its own. Why is that? I'm running 10.4.8 and I have the power settings in preferences set for "Better Energy Savings".
my powerbook keeps going to sleep automatically! i'll be using it one moment, the next it just goes to sleep! it's a 15" powerbook g4 with the latest software updates. i just set it to 'never sleep' in energy saver. hopefully that keeps it from going to sleep all the time. but in the mean time, any one know anything about this prob and what to do?
I have a 500mhz iMac G3. I just got it so it has a fresh install of 10.3.9, but when I try to put it to sleep the screen goes off, and then comes back on immediately.
My coworker is having some problems with his iBook G4 and I (being the mac guy I am) volunteered to help set it straight. I have encountered a bit of a snag that seems quite strange to me. The problem is that when the computer boots and gets to the login screen, it goes into a deep sleep and can only be revived by removing the battery. It stays at the login screen for about 3 seconds before this happens. Unfortunately, I didn't know about this in advance so I don't have my usual supplies (OSX CD or a Firewire cable to go into target disk mode so I can poke around from my MBP). If the sleep problem were not strange enough, I cant boot into single user mode! It just keeps a black screen up. Verbose startup does the same thing. Has anybody here come across a problem like this before?
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.
I've got a 1.5 GHz 15" PowerBook G4 with 2 GB RAM. Despite its age, this machine is quite good and, though slowly, does everything I need it to do. Within the past week or so, it's suddenly decided to take a very long time to go to sleep... about a minute or so. It does not matter whether or not I simply close the lid or give it the sleep command from the Apple Menu. Before this happened it took the computer about 1 second or so to get to sleep mode.
I have an ibook G4 14" 1.42ghz.I have it plugged into a power adapter almost always. It has been plugged in in both instances/I recently put it to sleep and when I return anywhere from 15 minutes to a couple hours it is shut down. I have a heck of a time getting it to power on. It took me several times, anywhere from 3-6 times to get it to turn on.
When I turn it on it goes through the usual loading procedures and after loading a window pops up saying the date and time are wrong and could cause applications to act erratically. The date ends up being 1969 and sometimes the time is wrong.
I have fixed the date and it still happens.
I don't know if this has affected or led to this but my battery has been shot for a couple months now and occasionally (probably 1-2 times a day) the power adapter (a cheap copy of apple's) would become unplugged from the laptop prompting the message stating you are on reserve battery and that the computer will go to sleep soon.
Does anyone know what is causing this? How much would it cost to fix it?
When I sleep my iBook (indigo clamshell), it does not dim to a black screen like it is supposed to...Instead I het a multicolor static looking screen...the hard drive does appear to power down and the green light slowly blinks as usual in sleep.
My Power Mac G5 does not go to sleep automatically. I had it set to go to sleep after 5 minutes of no activity. At least 5 minutes past but the computer failed to go into sleep mode. What could be preventing from going to sleep after the specified time?
My iMac G5 (rev A) shuts down immediately after i put it to sleep mode after just starting up the computer. The longer the computer has been on before I put it to sleep, the longer it takes for the computer to shut down while in sleep mode. I already did the hardware test and it said there were no problems.
My Imac does not remember how to sleep. Put it to sleep and it turns off. It also wont sleep on its own. The screen goes to sleep but the light on the bottom never flashes like it used to when it sleeps. I tried opening the back of it to reset the thing that controls the sleep and power end of it but that did not do it. I hit that button (under the manual power button on the board) when it was not plugged in, if that makes a difference. I also reset the Pram. Any ideas on what else I can do?
I was wondering how/where the sensor is/works to tell the computer to go to sleep when the lid is closed. I am doing some mods (discussed in the marketplace forum) and would like to try to keep that sensor intact if at all possible, but i realized I have no idea where it is located or how it senses that the lid is closed on these.
I searched the forum a bit and found nothing, and can't find anything in google other then sleeping problems... unless I just am horrible at googlin.
This is a phenomenon that I have experienced on a Blue & White G3 and a Gigabit G4, and in OS 9 and OS X: Whenever the hard disk spins down, the mac goes really slow even after it spins back up. I have to set the Energy Saver settings to keep the HD and computer from going to sleep (same result when computer goes to sleep). The problem is only fixed after I restart the machine. Same result with different hard drives as far as I can tell. Does anybody else have any experience with this or any additional explanation?
Recently my powerbook g4 aluminum 15" won't wake from sleep mode, and i can't turn it off with the button. When the computer does turn off the only way i can get it back on is to open it up and reset the logic board by disconnecting the back up battery for a little bit. I've tried reseting the PMU,
I have a PowerBook 12" on Tiger, 10.4.11. It is having occurrences of waking despite the closed cover. The cycles of wake/sleep are sometimes quite fast (seconds). I fear thrashing the HD. Here are excerpts from system log, followed by console log. The latter shows repeated instances of: AlsPB12 /usr/sbin/AppleFileServer: AppleFileServer ResetATalkService race detected. Which seems to implicate ATalk - is that AppleTalk? What relevance does AppleTalk have in today's systems?
