Re: powerbook wont come back from sleep mode

I have the same problem. PB G4, 1.5 GHz, bought in '04. When I put it to sleep by closing screen or manually it will not wake up. I have rest PRAM and PMU. Still nothing. Also, it was shut-down unexpectedly a few times and wouldn't restart unless I reset the PMU. I don't have anything but power cable plugged in (I think the cable and battery are ok). Any suggestions?

Hmm... very interesting. Mine has been doing this as well and just recently. I thought it might have to do with me using the PCMCIA slot. That was the newest thing I've done when I noticed that when it goes to sleep, I can't wake it up unless I force it to shut down (hold the power button down) and then restart again.
It may be something else. Like an Apple Software Update. That's my only deduction, but I don't know which one. Unfortunately, I don't log what and when I update. But I am one of those who updates frequently and doesn't wait to hear what others' experiences are before I let the update run.
It is annoying. Thankfully, not happening when I have left important work on in the background. I am going to shut off the "sleep mode" in energy saver so as not to risk losing work.
So I, like you, will wait to see what other people say.
Mine is a "new" PowerBook from eBay and it wasn't exhibiting those signs before. Just recently, like last week. (When I started using the cardbus slot with a USB 2.0 card, so I could have more slots available on the left side... yes, I know the PowerBook already comes with USB 2.0). Model A1106 at 1.5GHz.

Satellite U400 wont turn on & when on wont come back from sleep mode

I have a Satellite U400 and its a year and a few months old.
In the last little bit it has been acting up, and it started with when the computer goes to sleep and goes to the black blank screen it will not come back from that.
The only way to do anything is hold in the power key till it turns off and then turning it back on. This brings me to the warning screen I have turned my computer off incorrectly. It has been doings this for a few weeks and started randomly out of the blue.
Then just today it wouldnt turn on at all, I was pressing the power key and the key itself would light up, and on the bottom right hand side the little lights would light up but wouldnt turn on, I kept pressing it over and over and over again and finally it did turn on. Once on I only used it for a few mins before turning off again and then would do the same thing, I kept pressing the bottom till it turned on. Its been on now and hasnt turned off again.
Not to log ago I had to reformat my computer due to me forgeting my password and had locked myself out of the computer. About a week after that is when the issues started. I am not all that computer smart, to be honest, I do understand something things, I can follow step by step to do something.
I really dont want to pay to have it fix I want to just do it myself and soon as its in great shape and never had any issues before.
Does anyone have any idea what this could be, or why it could be?
I am thinking about reformatting again as I am worried that didnt work out right the 1st time or something.
Or if this is something that needs to be repaired does anyone have a clue on the cost of it?
Thanks ^_^

hi aev270,
sounds like a serious problem to me.
try the following: take out battery, cd-rom, hdd and try again.
if it starts up without this components - you got lucky!
this means it probably a software issue (but i dont think so - sorry)
do you see the toshiba logo / bios messages? no - the you are in trouble.
this strange behaviour could depend on many things: defektive components like ram or grafics... or (badest thing) the mainboard...
if you have still warranty on it you should go to a servicepartner having the system checked.

Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP

Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP. Each time closing the T400 lid and try to make the laptop into a sleep mode for some time, it does not properly come out of sleep mode. Login screen is able to see when opening the lid for the first time, but it only seen for a while before then a black screen on T400 Thinkpad appears. Sometime the hard drive activity can be shown also. And then, to come back I had only one option to hard re-boot.
I tried Fn+F4 and power button once to come back but no use.
Please provide me some solution for this?
Thanks in Advance.

oh sorry and its been closed inbetween uses. When i open it the keyboard doesn't light up and it makes no sound.

TS1819 Mac OS X 10.7.4. How do I configure my network settings so I don't have to enter the password to my wireless router every time I start up or come back from sleep mode?

When I first got my MacBook Pro my wireless network at home (Linksys Wireless Router) popped right up and I entered the password and had no problems automatically connected after that. I went to a friends house this weekend who also has a wireless router named Linksys, obviously with a different password. Ever since I connected to her network I have to enter my network password at home everytime I start my computer up or wake it up from sleep mode.
My questions is what caused this to happen and how do I reconfigure my network settings so that I don't have to re-enter my password all the time?
Thanks

Mac Pro Crashes Everytime Come back from Sleep Mode with Logic 8 Session on

Hi All,
I just got this new mac and have Logic Studio Setup on there along with VSL. I use Apogee Ensemble audio interface via firewire and have a Motif XS as my midi controller.
This morning I was in the middle of a session in Logic and then put the computer to sleep for an hour or so. I turned it back on and my 2nd monitor (right dual monitor) said I had to restart my computer. It was locked up. I restarted it and put it to sleep again after 20 minutes and came back 1.5 hours later and the same thing happened.
So, now I restarted it and it has not done it. Any ideas to what is the problem? Everytime i restart it says Mac OSX unexpectedly quit..
Please advise as this is a brand new computer and maybe I'm doing something wrong. Thanks.

I have an Ensemble also. Most likely, the issue is with the Ensemble firewire driver. It doesn't support sleep mode.
In any case, I would suggest shutting Logic down and also turning off the Ensemble if you're going to put the computer to sleep. I know that's a bit of a hassle, but it will solve your problem.

Just upgraded to OSX mavericks on macbook pro mid 2011 version. Having a big issue here that whenever my mac comes back from sleep, i.e after I open the lid, the screen flickers and there is an error of Finder not opening properly. Any fix to this?

Just upgraded to OSX 10.9 mavericks on macbook pro mid 2011 version. Having a big issue here that whenever my mac comes back from sleep, i.e after I open the lid, the screen flickers and there is an error of Finder not opening properly. Any fix to this?

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

My Outlook prompts for password every time it comes back from sleep or started

I've Microsot Outlook for MAC 2011, version 14.4.1 installed on my MAC Book Pro Retina Display with OS X Version 10.9.2 and everytime my outlook comes back from sleep or is started or there is a little fluctuation in Wifi signals, prompts me for my email password. I checked the option of save my passord, deleted all previous passwords from Keychain but it doesn't works, so please help. My email at my official domain (not free domains) address is configured perfectly and my send and received is working fine.

I have that problem in Outlook, too. When I get the Yes/No dialog box, I simply click "No" and my machine continues to receive mail.
It's most certainly a pain, but coming out of sleep, your network doesn't kick in for a minute or two. I don't think that it's really a bug in either OS X or Outlook: it just takes that minute or so for the network to wake up.

Satellite P850-30W - Fan does not run after coming back from sleep mode

I got a Toshiba Satellite P850-30W with bios 1.90.
Sometimes the fan does not run at all after coming back from sleep mode on windows 7.
This has happened twice (maybe more times without me knowing), and Ive had the computers for a month.
Normally the fan starts running when the CPU gets over 50 celsius, and stops under 50 celisus...
I tried running Prime95 when this fan-issue occured and the computer temps got dangerously high (close to 100 degree)! the fan did not start at all
...this error could potentinally damage the laptop...
to get the fan running again I have to restart windows
anyone else experienced this?
I guess the fix would be to never use sleep-mode...or toshiba needs to fix it with a bios update.

What kind of answer do you expect here in user community?
Exact info about the fault? I dont think that somebody would be able to provide exact answer but just speculations
In other Forum you can read about Satellite notebook; but is it exacts the same model?
No, it seems to be an L650 series. Its completely different series .
From my opinion its not software related problem.
BIOS issue?
Well, in case it would be a BIOS issue, the problem would appear always and not sometimes after being shut down 200 times.
It could be a hardware related issue. Memory? Maybe
In my personal opinion to get more details hardware diagnostic software should be used in order check the hardware for possible malfunction. Thats my personal opinion

PowerBook won't wake from sleep mode

My PowerBook G4 won't wake from sleep mode. I open the lid and nothing happens. I hold down the power button and nothing happens. I resetted the PMU and it will wake up and I am able to login and then it goes back to sleep mode. What should I do please help? And if my computer is dead, is there any way to retrieve my information saved on the hard drive?

this would happen to me when my battery was dead. you test the battery life? (little button on bottom near battery)
I'd make sure it was plugged in and let it charge for 10 minutes or so. then try restarting it if it doesnt wake up by itself.

After upgrading to 10.6.6, major problems coming back from sleep mode

I updated my macbook from 10.6.5 to 10.6.6 and now it is unresponsive frequently after coming back from sleep. The computer stops responding and I have the spinning beach ball on the screen forever. I couldn´t find any correlation with the programs I am running.
I used Onyx to clear all caches, rebooted, etc but nothing seems to help...

I have the same issue, I've found though that it seems to happen only if i goto sleep mode after logging out of my mid-2010 MBP. As long as I remain logged in and put the MBP to sleep it does not lock up with the spinning beach ball.
This lock seems to happen just as I click on my name to login after waking my MBP from sleep.
I have no peripherals, except maybe the power adapter, but it seems to happen regardless of if the power adapter is plugged in. I've done repair permissions in safe mode as well as disk scans.

Windows wont wake up from sleep mode.

I have a Macbook Pro (7,1) running OS X Lion(10.7.2). This week, I installed Windows 7 Professional using bootcamp 4.0. Everything works great, except waking from sleep mode. I searched various forums, reset PRAM parameters but the issue persists. Now, everytime windows goes to sleep, I have to hardboot by holding the power button. Windows restarts saying the shutdown didnt happen properly. Pl.help.

I came across these two useful links. The problem is not gone but is less frequent now.

John Robbin's solution of resetting PRAM/NVRAM addressed the problem but only temporarily in my case. The problem would recur in an hour.
Abhishek's blog address the opposite problem, but his solution of not having any programs in windows start up helps. I removed skype from the startup.
I also started using Parallels to bring up the bootcamp windows and that too provided a workaround.
Looking for a cleaner solution.

When trying to log back from sleep mode, the screen behaves as a rotating cube, with the mouse pointer in the top left corner. Hangs.

iMac OS X Ver 10.7.3
21.5 Inch, Mid 2011
2.5 FHz intel Core 5
12 GB 1333 MHz DDR3
When the computer in woken from sleep mode we see two login options (bineg used by two users).
But when we try to login, the screen just behaves as a sluggish rotating cube.
Nothing works, we just have to hard boot at this time.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

MBP 10.6.4 wont wake up from sleep mode

My MBP is connected to an external monitor and i keep the lid slightly open to keep it running cool (last MB I had overheated and caused battery issues, so was advised to keep lid slightly open). It works fine until it goes to sleep mode, after which it wont wake up. This is annoying as I lose data on documents Im working on as I have to force it to restart.
Is there a solution to this ridiculous issue?
