Powerbook g4 intermittent failures

My powerbook g4 seems to work fine and then suddenly it stops and asks me to reboot the machine. This problem has plagued my machine for about 2 months. I even did a clean install of Mac OS 10.4 (tiger). This problem still persists. I am pretty sure that it is not a software issue. I have attached the exception trace below, pleas help. TIA shyam

The RAM is factory installed. There is about 69GB memory available on the HDD. Also I had OS 10.3.7 before I went to 10.4 and the problem was present when I had OS 10.3.7 and now in 10.4 as well. There doesnt seem to be any common denominator to the crashes. The machine just Freezes and asks me to hold down the reboot button till the machine restarts. I forgot to include the exception trace the last time. Here it is. The last part of the exception trace contains all the information about the machine.

Intermittent Failure of incoming calls to Response Group

Hello,
We're running Lync Server 2010 and intermittently calls coming into the response group don't ring the attendant or take a long time to start ringing. We ARE seeing events in the event log pertaining to the LS Response Group Service as show below. I

Calls will begin to come in again after this but it appears the service is recovering from some type of failure state.
Thanks for any help!

Did this issue happen to multiple response group?
Did this happen to calls from PSTN calls?
This problem is mostly related with network issue.

Apple Mail and Google Apps (personal domain) - 554 554 Denied Mail Delivery Subsystem (Intermittent Failure)

Hello,
I am having problems with my Apple Mail and Google Apps and I don't know what to do. I have been using apple mail with google apps for a few months now with no complications. In the last week I have recieved a handful of messages from the Mail Delivery Subsystem citing error "554 554 Denied". I know that the emails I have tried to send to are real emails and are entered correctly. I tried to send directly from google apps to one of these people today and it worked so I assume the problem is with Apple Mail, or is intermittent. Adding to my frustration is that it works with some people and not with others so it's hard for me to see exactly what is causing the problem.
Any ideas?
I'll include a copy of one of the Mail Delivery Subsystem emails I recieved - excluding the email address and message body.
Thanks for your help!

Intermittent failure to boot, flashing question mark or white screen

So, I've had two MacBooks with similar problems (I am a Mac consultant). The first one would intermittently boot to a white screen, often enough to be annoying. This current one is occasionally booting to a flashing question mark. My first thought is, of course, the hard drive, but in both cases the hard drive tests fine using SMART Utility, which is usually great at giving advance warning when a drive starts experiencing hardware errors.
On the first MacBook, the one with the white-screen boots, I tried reinstalling the system with no effect; replacing the drive eventually made the problem go away. The current MacBook, with the question-mark boots, has already had its drive replaced once, when the stock drive failed.
I will reseat the drive, which is all Apple could suggest. I just wonder if anybody else had experienced something like this and can offer any information about what might be going on.

Thanks for the reply. Aside from finding that holding the mouse button down at boot might cause a flashing question mark, I already knew all that. I will ask the owner if she is leaning on the trackpad button when she starts up her computer in the morning.
I've already reset the power manager and the PRAM; we'll see if that makes any difference. The puzzling thing here is that the problem is intermittent.
I also need to ask her if, when the computer does boot to the question mark, there has been a chime first. Somehow I think there has to be, for the system to have gotten as far as looking for a boot drive. I couldn't find anything useful in the logs; not surprising, since if it can't find a drive to boot to, it won't have anything to write a log to.
Again, the mystery is why the failure to boot is intermittent. If it happened every time, I'd know what to do!
Thanks

Powerbook G4 Intermittent Start Up Issues

Afternoon Everyone,
I have a Powerbook G4 1.67ghz 15". Unfortunatly I am having issues we startup on the machine as of late.
I would press the power button receive the Start Up Chime as normal but where I would normally see the screen pop up the Apple Logo I just get a unlite screen.
I can here that the Laptop is doing something in the background by the HDD Noise, I havent attached it to a External monitor as of yet, But was wondering if you had any ideas?
Thanks,

Hi there,
Afraid not, doesn't matter what power source it's using.
Sometimes it can come on first time over times it's takes 3/4 attempts.

SGD 4 6 AD intermittent failures

Hello all
I have an issue with SGD 4.6....
The infrastructure:
2 SGD 4.6 in array config
1 AD for authentication
First time I had authentication to the AD and I saw the tree of the AD on the SGD and every thing worked fine, one day I just couldn´t get the tree.
The next day I found that I could autenticate with the AD in both servers, at the afternoon once again I lost auth in one of the array and a few minutes after on both servers, next day at mid morning I got authentication in one serverver, I restarted the second one and gained authentication again.
When i try to set up the authentication in the global conf during those outages I got this message.
*errorLDAP Connection Error
Failed to connect, no servers available[ dcexternal-srv.company.com.gt='javax.naming.AuthenticationException: GSSAPI [Root exception is javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7))]]'; ]*
If I change the user for autentication (I now is not the one to get acces i got this message)
LDAP Connection Error Fail to connect, invalid authentication credentials
I´ll apreciate any help with this issue, is killing me and I have a whole project waiting to solve this.
Regards,

Hi there,
The error:
GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7))
means that SGD cannot find an authentication realm for the AD server being connected to and therefore cannot connect.
If your AD environment has more than one AD server check you have a domain_realm mapping in your krb5.conf file for the network domain company.com.gt. If the mapping is missing, assign an authentication realm to the company.com.gt domain.
If your AD environment has only a single AD server, were there any DNS outages around the time of the AD failures? DNS outages can mean that SGD cannot resolve the hostname of the server and therefore cannot work out a domain and/or an authentication realm to use when connecting to the server.
For the LDAP issue, you may need to reconfigure the search filter used to find users in LDAP as the default values are sometimes not adequate for AD. The following blog entry should provided more information on reconfiguring this value:

Hope this helps,

Intermittent failure to send mail and/or save sent...

Several times now I have sent mail & got no record of the sent mail - no settings change, just mail server behaviour.... I have set Mac Mail up for IMAP and asked to store sent messages on the server. Most times it is fine, but occasionally fails to save the sent message, although the message is delivered to the recipient.
More worryingly, and on random occasions, my sent mail is not even delivered - with no failure notice. BTYahoo server seems to deliver (goes ok) but then simply ignores or loses the mail, even though it appears in my sent mail folder. Other times I get no record of sent mail. Mac Mail doesn't seem to have read receipts as an option, so of course the only way to find it hasn't been delivered is when I speak or email again and am told it didn't arrive. Turns out that it fails to be received by all recipients, not just one, so seems to be a BTYahoo issue, not another mail server in the WWW.
Has anyone else discovered that mails sent aren't being received or stored? Or have ideas why this might be happening?
Certainly isn't acceptable mail server behaviour....
Cheers
Andy

I've been having problems with my BT Yahoo mail since day 1 (July 9th). It nearly always fails to send the first time but then sends fine the second time I try. For about an hour this evening I wasn't able to send or receive at all because of a bunch of acronyms that the server had stopped supporting.
I have no idea what's wrong or how to fix it. I just figured you'd like to know you're not alone.

ICloud password not accepted, intermittent failure and must be reset each time

So, my wife is becoming manic depressant when she tries to use her phone, computer, whatever... on icloud. It will work fine for a week or two, then suddenly the password for the same account she has had no problem with for the last 4 years doesn't work any more. I then get called in to reset her password, re-sign in all of her devices, and she and I are happy once again. This has happened a ******** amount of times, (more than 10). I have went through the entire process of resetting all of the security questions... blah, blah... tech support... turn off, sign out all devices, blah blah... turn on, sign back in, on and on... update the computer, soft reset, hard reset, "upgrade" to the new stupid operating system that she really hates, blah blah, update the phone to an even worse OS,... on and on. Honest. I've tried everything. Everything is the latest model, and software version.
Does anyone out there actually know how to fix this intermittent problem? There is no solid pattern to the time intervals. It can happen within hours, or weeks of me resetting the password and signing in.
Lately, I have spent more intimate time with my wifes Apple devices than her, and this is very disturbing for me. (and her)

Hi,
Whilst Apple IDs that end in either @mac.com or @me.com they registration pages do not tell you that if you are going to be using it as an AIM Screen Name the password has to be 16 characters otr less. (This is an AIM server limit)
At some point you will need to update the password.

HP Pavilion p6510f Desktop intermittent failures - Antec 25 430 WATT Power & NVIDIA GEFORCE GTX 650

After installing a new power supply and video card (Antec 25 430 WATT Power & NVIDIA GEFORCE GTX 650), my system became unstable. It worked fine for the first 3-4 hours then had a BSOD (blue screen of death) with kernel_data_inpage_error 0000007A and later a critical process failure 000000F4. I've done all of the tests listed on this page as well as removed and replaced the cmos battery:
http://www.faultwire.com/solutions-fatal_error/KERNEL-DATA-INPAGE-ERROR-0x0000007A-*1137.html
All of the tests passed and no problems were found and yet the system still fails after 3-4 hours of use.
So, I removed everything from my system and restored it to it's original settings. It seems to be back to normal now (but, we'll see for how long).
This experience has demoralized me. This is due to the fact that I've heard of others having difficulties trying to upgrade their systems. Seems like there is about a 50% success rate unless you know what works from past experience. I feel that the only way to get a system that has good graphics now is a well tested gaming box (PS3, XBOX, or Wii). Is there any recommended or possibly well tested setups for this type of system that could give me the quality of a GEFORCE GTX 650 without causing blue screens or cause instability for my computer?
Since this computer comes with ATI and AMD parts, I presume maybe getting an ATI or AMD graphics card would work? Regardless of the graphics card, the 250W power that comes with this system would most likely need to be replaced. Are there are any power supplys that you recommend or possibly tested?
I realize there are a few questions in this post, but I have one more. Are there any motherboard analysis tools to enusre nothing has gone wrong with the mother board? When the blue screens were occurring it seemed to make strange noises from the hard drive as it it were thrashing and after rebooting it would sometimes fail to recognize the existance of the hard drive as well. Since all of the hard drive tests were successful (I also ran SeaTools), this leads me to believe that the power is inssuficient, but I'm now fearful that if I upgrade the power it will only cause more problems.
A paying customer,
Zintage
This question was solved.
View Solution.

So, using the standard setup still makes strange noises at various intervals, but not as frequently. I have a bad feeling that it has caused disk drive problems based on the fact that:
1) Strange noises are now occuring during particular load times (although rarely)
2) Computer crashes (although, it no longer crashes now that I'm back in it's regular setup)
3) Occassionall it has really slow access times
These symptoms fall into the category of a failing drive based on the following site:
http://www.lifehack.org/articles/technology/how-to-tell-when-your-hard-drive-is-going-to-fail.html
I'm going to return the power supply and game card and look to investing in a new hard drive in case this one finally decides to go to valhalla.

E1000: Intermittent failure when uploading

This week, I activated AT&T's U-verse Internet service (which works well and faster than my previous DSL service). My problem deals primarily with uploading, as follows.
I'm a web developer. I routinely upload files to my server using FTP with Dreamweaver (CS3) on a Mac (OS 10.5). Since my switch from DSL to U-verse (which provided the Linksys E1000 router), half the time I attempt to upload a file or files to the server, the transfer goes quickly. Unfortunately, half the attempts I make get hung up; the progress bar moves verrrrry slowly, then stops and tells me that transfer failed becuse it timed out.
I've reloaded the Linksys E1000 software, hoping to fix this new problem. Sadly, that didn't correct it..
What might cause the E1000's intermittent uploading? What's a recommended fix?
Thanks, in advance.

Yea, I can't think of anything either. It's clearly not your router since you said that it didn't work when connected directly to your modem. Usually people don't have problems when they connect directly to their modem, but you said that it didn't work at all when you tried that. The other twist was that you said it worked a few times with the router connected.
If I were in this situation, I would reconfigure my ftp settings from scratch. If that didn't work, then I would contact the ftp server's host and tell them about my problems to see if they had any suggestions. And if that didn't work then I would contact ATT. I'm pretty sure the host would have a lot more information and solutions to fix this issue.
I don't work for Cisco. I'm just here to help.

WOL from hibernation intermittant failures

I have arch linux 64bit installed on an Acer Revo 3610. This is an intel atom 330 mini pc with nvidia ion graphics and arch works well on it.
Wicd controls the ethernet connection, the revos also has a wifi an wicd seems suitable for my slip+openbox.
PM-utils works well for both suspend and hibernate, but very occasionally (say 5%) when hibernating, the ethernet fails to stay live and then the power switch needs to be pressed to get the resume to start. In the normal case I can see that the ethernet connection is 'live' ie the far end light on my router stays lit. I have set the BIOS to allow wakeonlan and have set up the mother board to supply some backplane power to support that (and suspend to ram). This liveness is not just residual as it survives power cycling the router.
Is there some way to guarantee that the ethernet will stay live at the end of the hibernate?

I posted in a related topic about my wife's
PowerBook's trackpad issues. We were experiencing
extremely frustrating cursor freezes since 10.4.3.
I just upgraded her machine to 10.4.5 and have been
problem free for the past hour. We'll see how it
goes over the next few days...
Anyone else have a similar experience with the recent
upgrade?
Nevermind... It's back, and in some cases worse than ever.
We had a rather embarassing situation occur at a coffee shop this morning. Someone noticed the PowerBook and was asking questions about Apple, Mac OSX, etc.
We were trying to show off some of the iLife features and the trackpad was extra-wacky... needless to say he was probably thinking "Nice computer, too bad you can't use it when you want to."
Ugh.

Powerbook 170 battery failure? Tips?

Have an old Powerbook 170. 2 batteries. External Lind conditioner/charger.
I've done complete discharge, recharging cycles, 4 hours+, even sequential ones. I then put either battery into the PB 170 and get only about 1 minute of use before the battery warning comes on.
As soon as I replug the power adapter, the battery level (software on screen) rapidly returns to 100%. Unplug, back to running on empty.
I've also left the unit in sleep mode with the battery inside the unit. Same thing.
How can I determine if the problem is the batteries or something with the PB? Is there something that needs resetting?
Any tips, tricks, suggestions appreciated.

You're more adventurous than I am clearly! Appreciate your feedback.
Well, my Lind external charger/conditioner has a Discharge button and cycle that is supposed to do a deep discharge (several hours) and then fast charge followed by a slow trickle charge back to 100% (another several hours). So that should have taken care of any memory effect. (Don't have a voltmeter.)
Now, what's intriguing is that I turned off extensions-- and my brightness slider control came back and the battery lasted for a time. No more instant decrease in power!
So, I'm now in the midst of ye old extensions testing. At first I thought it might be Wiz Tools, a wonderful utility for the old powerbooks, as it has software for controlling the brightness settings. I figured it had gotten stuck!
But that's not it... now the suspect is Ram Doubler.
What's odd, though, is that all these used to work on this computer!
Hmm... just turned off RD and the brightness slider control is working again and the battery doesn't instantly go down (!!). On the road to a solution I think... maybe the baterries are old, just not that OLD! Perhaps an RD pref setting has gotten corrupted.
I tried resetting the PMU with the two paper clips in the back. That didn't make a difference.
As to resetting PRAM, does the old trick of option-apple key-p-r on start up work on PB 170s? Unclear... http://docs.info.apple.com/article.html?artnum=58416 I'll just have to try it and see.

WTR54GS Intermittent failure mode

I have a WTR54GS and have used it successfully for many years (about 5 years) as a travel router. For the most part it has worked like a charm.
Recently it has exhibited a strange problem. It will suddenly *stop* working as a wireless router, and the lights flash in a rhythmic pattern with about a 2 second cycle time. I can't figure out what causes this, or what to do about it. The big security button, which is normally an amber color in normal use will flash white every two seconds, and the other lights flash at different, regular times. It is clearly displaying some sort of distress code, but I don't know what it means.
It will, however, sometimes fix itself. I left it running all night without problem, but then about 8 in the morning, it suddenly goes into this mode. At that time it becomes undetectable as a wireless network -- it no longer appears in the windows wireless lan list. I sat and wateched, and about 10 minutes later it stops doing that, and becomes a wireless lan again. At other times I have unplugged it, and plugged it back in. Sometimes when you plug it back in, it works, and sometimes it continues in the failure mode. It is not overheated ... I have unplugged it for long periods (e.g. 1 hour) and found it still failing when plugging it back in.
Right now, however, it is working fine, and I am submitting this message using it in wireless mode.
I have firmware version 1.0.15 which is the latest version listed on the Cisco site.
Does anyone have any idea what the flashing lights means? OR what to do about it when it happens?

Sounds like it's dying. You can try upgrading/reflashing the firmware and resetting the router.
The box said windows xp or better... So I installed Linux!

WRT300N Intermittent Failures

I am having intermittent problems with a recently purchased WRT300N wireless router.
Wired connections ALWAYS appear to work OK. I am using a wired connection to compose this message right now.
Wireless connections work for a few days and then the wireless stops working for a few hours and then seems to "fix" itself. For example, according to the DHCP log on my router:
Wed, 28 Feb 2007 18:11:50 received DISCOVER from 00:17:AB:E9:6B:BC
Wed, 28 Feb 2007 18:11:51 sending OFFER to 255.255.255.255 with 192.168.1.101
... repeats every 20 minutes or so until ...
Sat, 03 Mar 2007 07:12:36 received REQUEST from 00:17:AB:E9:6B:BC
Sat, 03 Mar 2007 07:12:36 sending ACK to 192.168.1.101
... no further entries in the DHCP log ...
Its now 1840, so its been almost 12 hours with the router failing to communicate with other wireless devices. There may be a correlation to the router renewing its IP address with the ISP (according to the router status page, the current lease is 4 days), but I cannot be sure.
A scan using my other wireless devices find other wireless routers (on other channels), but not mine.
Yes, I have the latest firmware (0.93.9).
Yes, I have gone back to factory defaults after loading that latest firmware & set my network back up again.
Yes, I have reported it to the support team (Incident: 070224-010921) but they suggested the first two steps and fail to respond to any further inquiries.
Any suggestions on "fixing" this problem or more diagnostics I could do to help isolate it and get a firmware update (or new device)?
Thanks.

My question is, Are you using an N-adapter to your wireless computer?
Actually, I am having problems now with B/G.
and for you firmware...there is a new firmware...1.03.3
Sure enough there is a new version (dated Jan 11). Curious the web site only now shows that (and the response to my incident submittal referred to the older version as well).
Will be trying your (and saber_tooth's) suggestions but since it took four days to fail this last time, it will likely be a while before I have new news to report.

Intermittent failure to detect LCD screen on bootup on Satellite X200

For a while now my X200 has been suffering an intermittent problem with the screen. When powering on it will issue one long and two short beeps and then proceed to boot but without the display.
I normally power cycle a few times and find that it sorts itself out but this evening it didn't want to cooperate so I dug out a cable for my TV and used that as a monitor and sure enough the machine booted fine and after POST immediately switched to the onboard display again. Does anyone have any idea what is happening and why?
A bit more background.
This has been happening on and off for a good month or so now.
I have used a variety of drivers both WHQL latest, and LV2G releases, but they all have the same issue.
At the moment I am on the default version of most the drivers and am going through the process of appyling the upgrades having just clean rebuilt the machine due to other issues (in a separate thread) but immediately before the rebuild, the probelm was just as evident and all drivers were the latest so I don't think it is a driver related issue or at least not one that appears to be solved by any of the existing releases.

Sounds pretty strange. Have you checked your BIOS options? Perhaps you should set it back do default settings.
Or try and install the recent BIOS version.
If this does not help, and as I read you already have done a clean reinstallation with latest drivers, I would suggest you contact local ASP, as beeping sounds are not that normal.
They can tell you what those sounds mean.
