MacBookPro2,1 Firewire / Clock Battery Issue... maybe Logic Board?

Hello,
I have this MacbookPro 17" since late 2007.
It has had the logic board replaced twice by Apple Service.
This happened over a year ago.
The cause at that time was that my hd suddenly was not working and after further diagnose it turned out to be the logic board.
The same day I got it back from Apple Service Firewire ports were not working... so I had to wait for another 2 weeks and finally got it back.
A couple of months later I noticed that the clock would reset to 1969 if I removed the battery and the magsafe cable.
A couple of months later I noticed that the firewire ports didnt work at all. ( FW400 / FW800 ). I didnt have the 2 weeks needed for Apple Service to do a diagnose and another 2 weeks to do whatever it is they do to fix it so I had no choice and stuck with the problems.
Now I finally got me another machine and can try and fix this. Any ideas?
Thanks!!!

Welcome to Apple Discussions!
Are you still under warranty? If so, Apple is obligated to fix these problems under warranty. Did you ever report back to Apple that you still had problems or get a case number?
You probably have the same MBP that I do, since I bought mine new in September 2007.
Regarding the FireWire ports, try the tips in this article:
http://support.apple.com/kb/HT1317
See if you can get them working again.
Regarding the clock, it sounds like the backup battery on the logic board is dead or discharged, so you are dependent on the main battery and the power adaptor for keeping the time. The backup battery probably needs to be replaced.
On general principles, it wouldn't hurt to do a PRAM reset and a SMC reset:
http://support.apple.com/kb/HT1379?viewlocale=en_US
http://support.apple.com/kb/HT1411?viewlocale=en_US
These resets will return everything to default values, and sometimes will cure some problems.
If nothing helps, then it sounds like your last logic board replacement is defective. I believe that both the 400 and the 800 FireWire ports are attached to the logic board, as is the backup battery for the clock. The battery can be replaced as far as I know, but I don't know if anything can be done about the ports.
Good luck!

IBook G3 start-up issues, possible logic board failure?

For the past few months the screen of my iBook G3 has been skipping and flashing and jumping at random times, quite often. If I move the screen to and fro it usually stops. I assumed this was just a bad connection with the LCD display and have basically ignored it.
Today, however, my screen froze completely while I was running Safari. Even the finder was frozen so I had to turn off the iBook by holding down the power button. When I restarted, it went through the usual start-up motions but after the grey start-up screen, it went to a blank blue screen. Only the mouse's cursor showed up at this point and nothing else. I was not asked to log in. Nor could I see my desktop.
I was just now browsing this board and found that the jumping screen issue I've been dealing with may have been logic board failure. Could this new blank blue screen problem also be a symptom of that? Or is it part of an overall hard drive failure?
The computer is quite old. I bought it in early 2002 and there's only about 2GB of space left on it at this point. So is it possible that the hard drive has crapped out?
I'm trying to restart right now in safe mode but it's been stuck at the grey start-up screen with rotating dial for about 40 minutes. Don't know what to do and I'm a little distraught at the idea of possibly having lost all of my files.
Any advice is appreciated. Thank you very much.

Hi, Christopher. Welcome to Apple Discussions.
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
If Safe Mode doesn't work, you will need to try repairing the hard drive from your Tiger Install disc.
Every time you have to do a forced shutdown instead of a normal one, there is a chance of hard drive damage and you should repair the hard drive, either by booting into Safe Mode OR by starting up from the Mac OS X Install Disc by inserting the disc and restarting your computer, holding down the C key as the startup chime is ending. Then click 'Next' at the language screen and choose Utilities > Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with either Safe Mode or the Install disc's Disk Utility, then start up normally and repair permissions from Disk Utility in the Utilities folder on the hard drive.
Here's hoping that a little hard drive maintenance will help. Good luck.

Is anybody else getting external MIDI clock tempo issues using Logic Pro 9 and OSX Lion 10.7.5?

I am having really serious tempo issues when sending midi clock to any external device - The tempo wavers and alternates around 5 bpm above and below the tempo set, and to be frank is totally unuasable when trying to clock arps from hardware synths.
I have the problem both with Logic and Ableton LE, as well as through both my MOTU Ultralite and Focusrite Liquid Sapphire 56 interfaces. I am therefore presuming this is a MIDI issue with the actual computer (MacBook pro, bought new last september).
I moved to Mac from PC, so I'm not totally up to scratch with the Mac architecture yet - can anybody shed any light on why this is happening? It's driving me mad!

Pancenter,
Yes.. I do see the occasional minor variations much like yourself when I sync up to my Oasys or more usually the Motif... to a fair sized and complicated project,,. Maybe +/- 1.. or on rare occasions +/- 2 bpm... but nothing close to the OP's +/- 5 bpm experiences...
It actually got better for me when I installed 10.8.x... along with the newest Motu drivers.. and in fact I can't remember the last time I had any unworkable issues with syncing though admittedly I haven't done that much syncing recently.
I do have a project coming up in the next 10 days.. that will require me to use the Oasys synced to Logic so I'll make a note of any issues i have and post back if any occur.
As an aside, I have recently been doing a lot of work with iPad Instruments and Arp Apps and Logic... and the sync as been rock solid over USB...

Does a 12" PowerBook have a PRAM battery on the logic board?

We got an 867MHz 12" Aluminum PowerBook in today that doesn't seem to want to hold PRAM values any longer than 5 minutes. It doesn't seem to matter if it's plugged in and using the AC adapter as the source or the battery (as long as it's charged, of course ).
I've gone through the typical battery of tests, like removing the Airport, add-on RAM, etc. but the problems persist. To get the item to boot, I've been repeatedly resetting the PMU (shift-option-command + power button) followed by a PRAM reset (option-command-P-R + power button) and eventually it will chime and start to boot. I suspect that I can end up isolating this to a specific set of steps. One of the oddities I've noticed is that when doing this, the power isn't actually off. For example, if I do the PRAM reset, the item will appear to be dead, but if I hit the caps lock key it's clear that the power is still on.
Once the item boots, I can power it on and off, and it will reboot, as long as I don't let it sit any more than 5 minutes. If I let it sit 5 minutes or more, then I need to go through this whole reset game again.
I've seen stuff like this happen on PCs that often have ROM/PROM batteries installed (sometimes removable, sometimes soldered to the board) that retain system settings. There seems to be something that looks like one of these batteries installed on this motherboard, but none of Apple's tech repair manuals reference replacing it, and it almost looks like its welded to a connector, but then again I'm not sure it's even a battery.
So the question is: Does this motherboard have a PRAM battery on it that's failing? If there is one, is there a replacement or replacement kit available, or am I barking up the wrong tree all together?
Thanks in advance.

From what I can tell, this device uses a "mega capacitor" to maintain the charge on the memory. It looks almost like a battery that I put into one of my old cameras. This capacitor sits between the trackpad and the optical drive. The owner of this system did a DVD upgrade himself and it appears in the process he actually knocked this capacitor off it's base on the mother board. It superficially APPEARS to be connected because there's a bar on the top end of the capacitor soldered to the motherboard that's holding it in place, but the bottom end broke off the motherboard.
The boss of our company theorizes as follows:
1. The PRAM and NVRAM has a high impedance, and when the mega capacitor is properly connected and without power, the discharge rate based on the RC time constant is very long (probably weeks...maybe months).
2. When power is turned off it's the duty of this effective RC network to maintain PRAM and NVRAM since the discharge rate is so slow.
3. With this capacitor busted off, the only capacitance that exists in the circuit is likely that of RF bypass capacitors and any other capacitors that may be used to filter out the supply. Since these are likely much, much lower in value the RC time constant becomes minutes instead of days/weeks/months.
I think this is a good theory for the following reasons:
1. If the unit sits, powered off, for any amount of time greater than 3-4 minutes and it's powered up, the unit comes on, but the CPU doesn't start processing. The optical media initializes, the caps lock key will light, and if you listen closely to the unit you can hear stuff running....but the CPU doesn't start. The conjecture is that the all PRAM/NVRAM parameters have been lost and when the CPU starts it sees nothing there and hence, does nothing. The unit is actually running, it just doesn't do anything.
2. If the unit sits, powered off, for any amount of time greater than 3-4 minutes, the following process will allow it to start up:
a. Turn the power on and leave it on for about 2-3 minutes. This is the dysfunctional state identified above, but what seems to be happening is that the effective RC network is being charged.
b. After several minutes, turn the unit off and then immediately turn it on.
c. The unit boots successfully.
d. We can turn the unit off, and turn it on again, and it will successfully boot as long as we do it relatively quickly (within a minute or two), but if it's left off more than that then the "game" identified in steps a-c must be repeated.
To me this implies the unit relies completely on the "mega-capacitor" to retain voltage on the PRAM/NVRAM. It sort of makes sense because the equivalent impedance of a battery is low compared to that of the RAM chips and it would have the effect of limiting the RC time constant needed for the unit to retain it's PRAM/NVRAM parameters for a very long period of time. That isn't to say the battery isn't supplying anything to the unit when power is off...it may very well be, but I suspect it simply isn't doing it to this circuit.
Does this theory make sense?

Random shutdowns - IT'S THE BATTERY, NOT THE LOGIC BOARD!!!!

Hey,
Just got my battery replacement, and the shutdown problem is GONE. Here's how you verify - run your Macbook with the battery removed, on AC power - the problem disappears.
The tech told me that it is a short in the battery, which tells the PMU that there is no power (whether there is or not!)...anyway, I hope this is helpful to all of you!
P.S. If you're also getting the vertical lines at startup, that's a video driver issue - just zap the PRAM so you can boot, and once booted, change the resolution to something else and back to normal - it will fix the problem entirely.
THERE IS HOPE!!!!

<<<dear ASPs! this is -NOT- true!!!! it is NOT the battery!>>>
probably thanks to you my ASP (DataQuest, Zurich Switzerland) only replaced my battery and handed back my MacBook unrepaired.
After the "repair" the problem at first was rare but after just three days I'm back at normal frequency of random shutdowns. I have to spend another two weeks waiting for my macbook. this time I'm sending it to Netherlands
I guess that it's really that badly calibrated thermal module causing these shutdowns. obviously the thermal module is irritated especially if you use your macbook often - so after 1-2 weeks of repair time the problem is barely apparent. (which causes unsuccessful repair - "testing after battery replacement worked fine" says ASP)

Logic board fine - battery still not charging

hi all,
i have a problem with my battery. here is the issue in the short form: my battery is not charging. the green led light is on even when the battery is not fully charged. the computer recognizes that it is plugged into a outlet, but it doesn't charge to one hundred percent. i've checked the outlet, tried different power adapters, and ran a hardware test on the logic board. all have not solved the issue. the logic board is apparently fine according to the test.
to complicate matters further and give you a better understanding of the problem, i'll describe in more detail the issue. when i turn on the computer after it has been shut down or if i unplug the adapter and then plug it back it, the battery charges briefly (and the led changes to orange) for about ten to fifteen seconds, before it stops charging. over the past three weeks since the problem started, i've gotten the battery to go from 44 percent to 76 percent simply with these short ten second bursts of charge. these ten second bursts only happen right after plugging in the ac adapter. once it stops charging, then it stays like that unless you unplug it and then plug it in again.
so guys, this is my issue. i thought that the only issues associated with this problem could be the power source, the ac adapter, the battery, and the logic board. the power source and the adapter are not the problem. neither is the logic board. although i am getting a new battery because of the recall, it was working just fine up until this issue. that is, it was able to be fully charged. i'm stumped and i don't know what to do. i would greatly appreciate anyone's advice. thanks so much.

I'm sorry it took me so long to see you message and I'm also sorry I do not have a solution to your problem which is exactly the same problem I have. I've done very similar things to it and still I have a problem. At this point my 12-inch is sitting idle probably awaiting a large repair bill. I've been dealing with this for over a year and if you look at the past postings on the discussion board you'll find out that more than a couple of people are or have had this power problem. I got my 12-inch G4 in the spring of '03 and a year or so later I begain to have the same power problems you have had. What has not happened to you, but has to me is that it refuses to either charge a new battery or even power-up pluged directly into the wall outlet. I've been hoping that maybe Apple would recognize there is a defect in this series of G4's and do free repairs, but I started turning blue from holding my breath.

Logic Board Battery Problem: Symptoms and Consequences

Hello everyone!
When I cold start my Mac - a 1.67 GHz PowerPC G4 - I get a pop up window with the following message:
"Your computer's clock is set to a date before March 24th 2001. This may cause some applications to behave erratically. Please use the Date & Time preference panel to set the clock manually. For more information, choose Mac Help from the Help menu."
I've been getting this message since I first got the machine this past November, but since the system clock is automatically set by the network (right after the message gets generated), I just close the window and get on with the rest of my day. However, I finally decided to call Apple Tech Support about it. They told me the symptoms indicate that the battery on the logic board has gone bad and if I want to get the battery replaced I need to send my machine to Apple to have this done.
Since it would be a major inconvenience for me to send the machine out for repair, I am wondering what additional functionality this battery performs. I am willing to live with getting this message every time I cold start the machine, but would not want to rung the risk of a major malfunction occurring as a result of not replacing the battery.
So - I am wondering, does anyone know what functionality this battery performs in addition to running the system clock? Also, what might be the consequences of neglecting to replace this battery?
All opinions are greatly appreciated 8-)

Well, that begins to narrow it down... 12", 15", etc.?
Again, what exact model PowerBook?
I use "exact" literally.
Perhaps this KB article will help.
It may well be the case that your PB has to be returned for an internal battery replacement, since there is no replacement listed for it in this previously-cited document. However, I'd be very surprised by that and can find no documentation to either support or deny their claim. You may want to call them back to double-check this.
There are some Mac portable models that do not have an internal battery, aka a "backup battery." Those Macs use a capacitor, rather than a battery, to maintain PRAM while the main battery is swapped.
I'm beginning to wonder if there's some confusion with AppleCare w.r.t. the terms "backup battery" vs. "capacitor" after reading the last paragraph of this KB article. If there is a capacitor problem, then you PB would have to be returned for service.
Good luck!

Mid 2009 applecare logic board and battery ADVICE

returning mac OS and mac hardware buyer here.
i have been questioning (read complaining) about the battery life (1 1/2 hours on safari) and the performance (spinning beachballs on startup, on wake and on starting safari among other things) since i bought this machine. i brought it in for the umpteenth time to the genius bar (they apparently only have 3 of these on record?!) because i had a break and i have a "service battery" alert.
i am being told i can replace the battery and the logic board based upon their diagnostics of the machine and i have FINALLY (Whoo-HOOO yippeee kayeeee'y!!) got a committment from a mac rep that i should be expecting 3 1/2 - 4 hours out of the battery and not 1 1/2 hours.
i don't really have an option here from everything i can tell but does anyone have any advice for me on this? warranty is up in February and from what i am being told i can bring it back if i bring it home and still only get poor battery life.
at the same time i am really unhappy (insert expletive) about having spent so much time troubleshooting this machine only to be told that the hardware seems fine or that the battery tests normal or whatever. this macbook pro 13 inch seems like it was a dog since the day i bought it.
my preference would REALLYT be to trade into mac on a new macbook pro 15" and i am wondering if i am instead i am going to have to just repair this machine (thank my lucky stars that i buy applecare) and empirically test the machine on my end to make sure that i am getting more than 2 hours per charge and that i don't have the spinning beachballs that i have had to have dealt with over the last 3 years...
i mean, i /have/ to fix this machine and monitor it over the next three months instead of them helping me cut bait with it by getting some financial incentive somehow to move into a new MBP is that right...?
TIA

thanks.
looks like it has now had a new battery and a new logic board and it is still failing hardware test for the battery.
they are now sending it out for additional testing to some other facility.
anyone had a similar experience?

NVIDIA issue: Apple not agreeing to replace logic board

Hi,
I have a 15" MBP purchased in Oct 2007.
This is what happened.
Watching videos, screen starts flickering, Then hanged. So rebooted manually. Happened 3-4 times and after that system won't boot.
Display comes, sound comes and then comes to gray screen of death.
Took it to ASP, guy says software issue and asks me to repair. I go home run the diagnostic test and get the error:
4VDC/1/40000003: VideoController.
Googled and found out about the NVDIA 8600M graphics processor issue.
Went back to ASP very happy that problem occurred with just 2 months remaining for the 4 yr warranty.
Then begins my ordeal.
ASP says because of the kernel panic, they cannot run any diagnostic test to confirm if its only GPP issue. They say some other component on logic board has failed so cannot give free replacement.
Raise it with Customer care who puts me through Customer Relationship Manager, she says she'll have Apple engineers validate it.
Comes back next day, says Apple engg ran test and found out its not GPP issue. I ask for results confirming it. She says I can get those from ASP.
Next day go to ASP, ask for results, they say we could never run any test.
I am a bit of technical guy myself. I understand that any malfunctioning hardware can cause kernel panic and graphics processor is pretty important one.
So what I don't understand is, how can Apple say its not NVDIA issue, without even running any test.
Called up customer care again, (this time was connected to different relationship manager) she kept saying the same thing, we did our test and find to connection to GPP issue. I asked her to put me through some technical person. She said she would do it and am waiting for the same.
What I find very frustrating is that I have found many instances where people found the same issues as mine and they got a free replacement of the logic board. Then why in my case Apple is not willing to accept that this is the same problem.
I need help from folks over here. What really are my options? What should I do?
I am hoping the Apple technical person understands what I am saying. But what if he too refuses to accept?
I cannot afford to spend this much on a logic board. Will have to buy a new one and that too non-MAC. (My wife would kill me if I buy another MAC and based on my own experience I would be very scared as well)
I am based in India.
Please help.
-Thanks

Finally some good news. Couldn't wait to share with you all.
Received a call from AASP that they have got the approval for replacement of logic board and I should be getting my laptop back next week. Yayyyy..
This is what happened today.
Today being a holiday I went there in the afternoon. Luckily the place was empty. So caught hold of the supervisor and told him lets sit together and work on the
issue. Told him if we suspect the kernel panic to be an OS issue then lets hook up another HDD and bootup the laptop. Thankfully he too obliged.
First thing he booted up in single user mode and ran fsck. HDD was all OK. Then I noticed that the background instead of being completely black had some blue
colored stripes. He probably noticed that as well but didn't say so. When I asked him if it was supposed to be black he said yes but also said it could be an OS
issue as well. Then he got an external monitor. But since the laptop won't boot we couldn't reach the stage where we can make use of external monitor.
Next he brought external HDD. It was detected but again laptop won't boot from it.
Then he got the NVIDIA Test Program on a USB stick and tried to hook it up. Unfortunately the laptop didn't recognize the USB stick. He then got the specs of
my laptop from Apple Site and brought up the TS2377. Then he gave me some nonsense about how my model was 15"MBP 2.2/2.4 GHz (Late
2007) whereas in TS2377, it just says 15"MBP 2.2/2.4 GHz, no mention of Late 2007, therefore my laptop is not part of affected batch. I was like, dude, what
are you talking about, its clearly mentioned manufactured between May 2007 to September 2008. Then he said, this model doesn't have "something" because of
which the NVIDIA test cannot be run. When I asked what that something is, then he just said nothing and cut short that thread of conversation. Then he tried to run
the test on his own laptop and to my good fortune even that laptop didn't recognize the USB at bootup time. It would detect when system was running. At
that point he pretty much ran out of all excuses and told me he would take the laptop inside and work on it. He told me he'll give me a call once he has an
update which he did a while back and gave me the fantastic news.
Although I am thankful to this AASP person for looking into it seriously, this whole episode has left a bitter taste about Apple's service in general.
First I never expected Apple product to go bust in less than 4 years. And if there is a known manufacturing fault then Apple should make sure that the
customer doesnt have to do running around to prove the issue.
The NVIDIA test requires the system to boot up. But ideally the test should be such that they should just be able to take the logic board and verify it somehow.
Its like, if the part has gone little bad then we can replace, but if its gone completely bad then we can't.
Also, Apple should look to fix issues in logic board rather than asking users to replace it completely (in the event they are not providing replacement). For all
we know the problem could be in $10 component that requires a $1000 to replace.
Anyways, enough of my rant. I'm just relieved that matter is resolved. I am thankful to all who replied esp tjk.
Wow.
As you and I already know, that machine is indeed one of the models that may be affected by the NVIDIA issue. It's difficult to believe someone would deny that. Anyway, your persistence paid off, and you should be on the way to a normally functioning MBP. Finally. It's too bad you had to go through all that, but I'm glad that worked out for you. Hope you'll post back with the results after the MBP is repaired.

Logic Board Error-No Firwire

I'm almost afraid to ask this question, but I just did a hardware test on my MDD G4 Dual Gig because I lost my firewire devices today. The Logic Board test revealed an error code fire 3/20. Is something fried? Can I replace it myself? This couldn't happen at a worse time because I'm editing video!!
HELP oh wise Mac people.

Hello! Sometimes the firewire ports "trip" out. Try shutting down and unplugging everything for about 30 minutes. Then restart and see if they have reset. Tom

Battery issue . . . maybe

Me again. I just got a new battery for my TiBook and it seemed to be working well until yesterday. I tried charging it overnight and at about 1AM (after being plugged in for around 4 hours) I noticed the power light was still orange. I flipped over my laptop and the battery charging lights were not lit up at all. It wasn't charging. Well, I unplugged it and went back to bed. In the morning, I plugged it back in and the light stayed green . . . but the book was charging. Now the light won't go orange at all, and the battery charges while the light remains green. Is this going to be a problem at all? Should I just ignore it? The only reason I ask is my computer has had quite a few battery issues in the past. Please let me know . . . thanks!!!

Hi
You can try to reset your PMU (Power Management Unit) for a start, it may help :

Otherwise I remember my G4 15'' had a battery issue one or two years ago, Apple replaced it as it was a flaw (battery was overheating or something).

Can you double check my logic and maybe provide alternate ideas? - Logic board charing issue

My situation is that I have two Core 2 Duo macbooks, model 2,1 and 1,1. One sustained a fall and basically still works as computer but screen is cracked, optical drive wont run and key board has some keys that broken of in a way that can't be replaced. The only thing wrong with macbook number two is a coffee spill. It won't charge the battery or run of the power adapter but will run on a battery that has been charged on another macbook.
I figure I probably have one fully functional macbook between the two. What I need to know is:
1. are these slightly different model numbers fully compatible for swapping out parts?
2. What is the best way to go about this in light of wanting to combine the display, optical drive, and keyboard from one mac with the logic board of the other. Should I think of it as a swapping of logic boards or cannibalizing a host of parts off of one back to the other? The former feels cleaner but the latter might be actually be less complicated and less work.
3. Is the logic board the firm culprit in the second macbook? Is there another possibility? Is there a clear spot where the logic board might be shorted that can be more easily repaired than the possible number 2 scenarios?

Look in "About This Mac" in the  menu for the serial number. They probably didn't copy it to the new logic board. They can download software to do this from a website restricted to Apple service departments.

Macbook PRO battery issues

I have a Macboon PRO1 5 inch and sometimes the battery shows a cross sign and the fan doesn't stop running. I sent in thrice to Apple for repair. Everytime it comes back with a new problem. Now my battery doesn't charge at all and discahrges very rapidly.Appple has changed everything they can think of, the power adapter,logic board, battery ,the battery connector, but that just seem to fix the problem. Did anyone else have a similar issue? Cause everytime I call Apple they just ask me to send it back in.

Well I did ask for a senior level advisor and even he said he can't do anything and that I need to send in for repair again. The whole experience with Apple has been so frustrating. I was hoping that if someone had similar issues like I did with the battery ,maybe I can simply ask again for a new power adapter or something(based on what others experience) without having to send it in again.

Iphone4s - iMessage, Call & battery issues

I cannont receive text or picture messages via imesssage every once in a while, it never appears to be an issue when i receive from OTHER phones on other networks. I am able to send the messages though. and this issue is not consistent. it happens every now and then.
While i was testing this, i also noticed that when i send an iMessage the receiver is seeing my email Id instead of my phone number. I donno how frequent it is, but i noticed it once.
also, whenever someone calls me i get the call very late, i.e. just when the caller is about to reach my voicemail or disconnect. I have tested this by dialing my phone from a number of other phone including iPhone 4 & 4S from At&t
coming to the battery issues, i ALWAYS have my time zone off(i put my clock 10 min ahead), so i dont see the issue others are facing. But once in a a while i can see the battery dropping from 80% to dead within an hour or two without any usage. I got my iPhone 4s on day 1 and this happened about 4-5 times till now. Everytime i saw this happening, i would terminate all the background apps but that dosent stop the battery from draining.
I went to the apple store yesterday to have it diagnosed and they sent me away telling that I need to make an appointment.
Is anyone else facing the same issues?
Please share the solution if anyone was able to get around these issues.

Hi,
I had battery issues with my iphone5 ever since I updated to the latest IOS. My battery was draining really fast and my phone was really warm. What I did to solve this problem was: Go into Settings>Mail>Fetch New Data>Push,and make sure you switch push off. In that same section make sure that fetch is set as manually. This means that you have to check your emails when you want to - instead of the notifications going off every minute draining your battery.
I hope this helps anyone with the same issue.

Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

MacBookPro2,1 Firewire / Clock Battery Issue... maybe Logic Board?
