Help Ibook not recognizing extra Ram!

Hi, please help, I have just fitted a 1GB ram to my ibook as recommended by the apple genius.
When I click on about this mac it still says 256ram.
Have I done anything wrong? Ive refitted it again and it still doesnt recognize it?
Is there something else I need to do?

bluebubble, Welcome to the discussion area!
Resetting the PRAM has nothing to do with it.
One or more of the following is true:
(1) The RAM isn't installed properly.
(2) The RAM isn't compatible with your iBook.
(3) The RAM is defective.
(4) The iBook's motherboard is defective and not recognizing the RAM.

Laptop not recognizing old ram

Hello everyone. First time poster here, needing some advice. Well I had applied new quality thermal paste and cleaned out the vents to my rig presario cq62. After doing everything, it's not recognizing one stick of ram. I switched them to see what will happen and I got the same result. Does that mean one slot is faulty? Does the fact that I got a bios error have anything to do with it. It was cmos 502 error but for some reason after it was shown, it booted without any problems except the time is always wrong which might be because if the error

I understand that your notebook is not recognizing the new or old RAM module in one of the memory slots on your notebook, and that your system displayed a CMOS error. Which slot on the system board is affected when you insert a new RAM module, and is it inserted by itself? I would be happy to help you, but first I would encourage you to post your product number for your computer. Below is a is an HP Support document that will demonstrate how to find your computer's product number. In addition, it will also help if you indicate which operating system you are using; and whether your operating system is 32 or 64 bit. The more information you can provide, the better!

Help! Not recognized by Windows / iTunes

When I connect my iPod using USB 2.0, I now get a "USB device not recognized" error on Windows XP. iTunes also does not recognize that iPod is connected.
I believe this problem may have been caused when my iPod was connected to a friend's speakers. When it first connected, the following error message appeared:
"FireWire connections are not supported. To Transfer Songs, connect the USB cable provided".
After pushing the Selct button to gt rid of the error, iPod worked fine in the speakers and continues to work fine with my FM tuner and other devices.
I've tried the following to fix this problem:
1. 4 of the 5 Rs. (Can't find a way to restore as I can't get iTunes to recognize my iPod).
2. Reinstalled iTunes.
3. Simple restart on computer.
4. System restore on computer.
5. Tried to update USB drivers.
6. Tried to load iPod in disk mode.
7. Went through all of the Apple Support articles for this problem and tried all of the reccomended steps.
As mentioned, my iPod works fine otherwise and I'd hate to have to send it away to be repaired if there is a simple fix. Also, my wife's Nano is working without problem on the same PC, so I have a feeling that this problem is iPod related rather than PC related (though, I could be wrong!)
Does anybody have any suggestions?
Is there a way to restore iPod manually (i.e. without iTunes)?

Hiya! I have had the same problems and have tried all the suggested ways to fix. None of them have worked. I have also rung the apple tech support helpline and they have told me i need to go to my nearest apple store and get my i-pod tested for errors and as my i-pod is out of its warranty period i will have to pay to have it fixed and pay for the courier for it to be sent to be fixed.
i have found if i plug my i-pod in via USB and the malfunction message appears if i hold down the menu and play buttons so it switches off just before the apple logo appears switch the hold button on sometimes i-tunes will recognise it. It kicks it off again 3-4 minutes later but i manage to get a few songs on in that time.
Its a pain in the backside but this is the only way i can get it to work.
Hope this helps someone

10.4.2 not recognizing extra memory module

I upgraded recently to 10.4.2, and now one of my memory modules is not recognized. the machine has the original 512M chip in the upper slot, but the 512M chip in the lower slot is not recognized. in the system profiler under hardware/diagnostics, i get:
Power On Self-Test:
Last Run:     7/15/05 7:57 PM
Result:     Failed
Failure type:     Memory
Memory slot:     SODIMM0/J25LOWER
anyone have any idea what's going on??? thx.

"However, I have another problem in that there is no startup chime on my machine, and hasn't been for a while"
Same problem with my PowerBook G4 - 1.5GHz - 512MB, only since the chime problem (not hearing it any more) has the problem with not recognizing the lower memory slot. Not certain if the two problems are related. So it seems from the discussions hear there are two solutions, $600 to repair, or purchase more memory to run in the upper slot. I do have to agree that it would be futile in my opinion to pay for the repair if the same problem emerges again, (as has been reported, at least in the forums,) meaning it could cost $1200 to fix (maybe).
"I think that terming the logic board, "fried" overstates the issue. In fact, the logic board itself is probably in good working order, thus its ability to report on the state of the lower RAM slot. The real issue is the quality of the connection from the lower slot to the logic board--essentially a bad solder. This connection can't be resoldered, so the logic board needs to be replaced."
This statement actually makes more sense then anything I have read so far.

Help: encoder not recognizing audio in mpg

i have to convery a number of mpgs into flvs using flash's
video encoder. the mpgs have audio, however when i bring them into
the encoder, click on settings, and then click on the audio tab,
it's all grayed out like it's not recognizing it has audio.
anybody encounter this problem as well?
thanks!

Hi liscola,
I'm having similar issues with Flash's video encoder although
I have an MPEG file with audio that I'm converting to an FLV. I've
been using the 'Flash 8 - High Quality' setting. It starts encoding
the file but then give me the following error;
2008-04-18 13:13:34 : ENCODING FAILED
- Source file: SourceFile.mpg
- Output file: ConvertedFile.flv
- Video codec: On2 VP6
- Alpha channel encoded: no
- Deinterlace: no
- Frame rate: 0 fps
- Key frame interval: 0 frames
- Video data rate: 700 kbps
- Width: 0 pixels
- Height: 0 pixels
- Audio codec: MPEG Layer III (MP3)
- Audio data rate: 128 kbps (stereo)
- FLV duration: 00:00:00
- Encoding time: 00:02:01
====================================================================
An internal application error occurred.
====================================================================
I have looked into this and there are other posts indicating
that the encoder possibly can't format MPEGS with sound thats over
44kbps. Other people have suggested to convert the MPEG to AVI and
then to FLV but when I tried that is just reduced the quality of
the video.
If there's anyone that can help with this issue I'd really
appreciate it.
Thanks Simon

Javac -help: 'javac' not recognized...why?

hi all,
i just installed j2sdk1.4.0_02, but i have a problem. in the dos prompt, when i type C:\>javac -help, it results in a 'javac' is not recognized error. why?
my PATH enviroment variable is this:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\ActivCard\ActivCard Gold\resources;C:\Program Files\Microsoft SQL Server\80\Tools\BINN;C:\j2sdk1.4.0_02\bin\javac.exe
what am i doing wrong?
thanks,
jeff

Hi, I installe dthe sdk1.4.0 but have no
C:\j2sdk1.4.0_02 dir (or anything relating to java).
Did I not do something right? I can run the java
command but not javac.If you don't have a directory similar to j2sdk1.4.0_02 then you did something wrong. You can try to search your system for javac.exe. If you post the exact steps you went through, someone here may be able to
help you.

PLEASE HELP - Projector not recognizing signal - No one seems to answer

Help!!! I cannot get anyone either at the Apple store or Best Buy to answer my question. I have a Macbook Pro unibody bought in Nov 2009. Of course it has the mini diplay port. I bought a mini display port to vga adapter. The projector keeps giving me the message that it is not recognizing a signal. I looked on a forum where someone said it a technology issue. They said to get a mini display to a dvi cable and then a dvi adapter to a vga. I purchased the cables. The only problem is that the cables will not work together. There are some pins on the male end that have no where to plug in on the female end. It is the 4 pins that surround the flat pin. Why would Apple make two cables that will not work together. Well anyway I am back to square one and still do have a solution to why I can't display an image to a projector from my macbook pro, It is very frustrating that Apple does not have a solution for my problem. Or maybe they do and no one has yet to tell me the right thing to do.

Whoever told you to buy the MDP-DVI adapter and a DVI-VGA adapter was utterly full of baloney. Your MDP-VGA adapter was exactly the right thing to use all along. It's possible that your adapter is bad, though, or that the VGA cable connecting it to the computer is bad. It's even possible that your MacBook Pro's mini-Displayport isn't working, or that the projector isn't working.
If I were you, I'd take the machine and MDP-VGA adapter to an Apple Store's Genius Bar and ask to have the port and the adapter tested for proper function. If the projector and VGA cable also belong to you, take the whole shebang with you and have everything tested together. Apple won't take any responsibility for a malfunctioning projector, of course, but they may at least be able to pinpoint the problem for you.

Ibook not recognizing my digital camecorder

I shot a video for a class project that needs editing, so I hooked the camcorder up to the ibook, and it's not recognizing it, it doesn't know it's connected. what do I do ?

Generally you set iPhoto or Image Capture to launch when a camera is connected. What exactly do you want to happen?

Please help - Battery not recognized, after totally drained

Dear all, need some advice on how solving this issue. My macbook just had its battery totally drained and now it is not recognized by it.
I have tried all "tips" from the FAQ, but none of them worked out
It seems this is a "common" issue as apple guys are listing as top 3 in the FAQs...
Need help as I am travelling outside US on a project and will be dead without baterries.
For those who cannot help, find my tip: DO NOT LET YOUR MACBOOK BATTERY FULLY DRAIN!
Thanks

Macbooks have worldwide warranties - so maybe if you have your warranty card with you - and perhaps even if you don't - you can go into an Apple shop and get it replaced - go to the genius bar and give 'em a big smile...

PSE 11 not recognising extra ram on an iMac

I have an iMac which had 4 gb of ram. Photoshop defaulted the usage to just under 3 gb. I installed another 8 gb of ram but PSE fails to recognise the extra ram
so I can only get it to use 3gb. If I reinstall will it recognise all my ram? Will I still have all my photos on the organiser?

Hi smudger1939,
PSE won't recognize the extra RAM after 3072 MB. As it's the highest which a 64-bit application can use. So even if you install even another 16GB of it. I won't be able to use that one. However, it's a benefit when you are using several applications parallely. The extra RAM will be used by other applications, and will not hamper your PSE performance.
So if you want to increase the performance of PSE, reduce the history states. You can also refer to this kb article for the same:

Ibook not recognizing external HD

I have an ibook g4 i.42 ghz and a western digital external hard drive that is only about 2 years old. Recently my ibook began to refuse to start up while the hard drive is plugged in via firewire (the hard drive can operate via usb also, but i need those ports for other things and firewire is faster). This had been going on for a while, but just the other day when i plugged in my external my ibook isnt recognizing it at all, even though its plugged in and the power is clearly on. Sometimes it shows up but i cant access any of the files on it, and itunes freezes when i try to open it (my whole itunes library is on the external for the sake of my hdd). I'm wondering if my hard drive has just run its course and is dead (great!) or if my computer is acting up. Any insights are greatly appreciated!

Hey saturn,
.. western digital external hard drive that is only about 2 years old. .. my ibook began to refuse to start up while the hard drive is plugged in via firewire .. Sometimes it shows up but i cant access any of the files on it, and itunes freezes when i try to open it (my whole itunes library is on the external for the sake of my hdd). I'm wondering if my hard drive has just run its course and is dead (great!) or if my computer is acting up.
Oddly enough I have a WD external FireWire 400 hooked up to my dual 1.2 G4 tower here. It's a 2407A and it's power supply died about a year after I got it. I have it running w/ the supply from an old Mac SCSI external and it's been fine for the last few years but last week it disappeared from my desktop. I looked at the FireWire bus under system profiler and in red letters it said the bus couldn't be read. I immediately pulled all FireWire connections and the profiler went back to normal (nothing connected). I found that the WD was pulling power through the FireWire cable and probably causing that bus to crash. With all cables pulled I shut down the WD external and it's supply. I then restarted the WD external and once it lit up and initialized I plugged it back into the Mac and viola it was there like normal.
So this experience just adds to my negative feelings toward WD and their general wonkyness.
I'd back up your iTunes on another drive.
Also we were talking about this around here a while back and someone said that the average lifetime of a hard drive is 3 - 5 years however a certain percentage of new drives will fail within 3 months. I think the number was 3 - 5%.

Ibook not recognizing RAM

ok, so my brothers laptop has the 256 MB built in, then it came with another 256 Stick in it, however, it said that the computer only had 256 (which was the built in), so we replaced the RAM stick with another 256, and it still isnt' recognizing it, still says just 256 built in... what is goin on here?

i know the RAM is good, becuase i bought a new stick for mine (identical laptops) and i gave him my old working one, i just bought a 512 instead of a 256 that it came with, so i am sure that the RAM is good, we don't have a bootable disc, cuz we got em from a school and all they gave us were the laptops and the power adapters. so ya, it isn't really worth it to replace the logic board in them, cuz one of em, the logic board was crap, and so we bought 4 and only have 3 working ones, so, if it is the logic board, consider this question answered.

Windows xp not recognizing 4GB ram

I am upgrading a computer from 2GB to 4GB ram. The BIOS recognizes the memory as 4GB dual channel interleaved, but when I get into windows it only shows 2GB.
The OS is Windows XP SP3
there is no onboard video controller
dxdiag tells me video card is an nvidia 7800 GTX with 256MB of ram.
I read about the video card address space issue but it doesn't account for the difference. It should still be at 3.5 or 3.75 GB available to the system.
I have tried enabling the /PAE and the /3GB flags in the boot.ini file one at a time and together.
I have also tried manually setting virtual memory to a different size as well as disabling it.
Any ideas?

IBook not recognizing optical drivve

Help! My optical drive quit.
I was at a family reunion, burning a couple of cd's, when it wouldn't mount a blank disc anymore. Now it does not recognize the drive. With System Profiler I get the following for the optical drive:
M@TRHHT@ CD-RW BW,8022:
Manufacturer: M@TRHHT@
Model: M@TRHHT@ CD-RW BW,8022
Revision: BA00
Serial Number:
Drive Type: CD-RW/DVD-ROM
Disc Burning: Not Supported
Removable Media: Yes
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
Obviously Something has gone haywire. Does this mean a new drive or can I force it to rescan or something to get the right info from the drive.
Don

I have heard this is prevalent. My wife ibook 1.33 doesn't recognize the optical drive as evidenced in the System Profiler.
She took it to an Apple store while in warranty and they changed the hard drive?!
I knew that the communication between the motherboard and the optical disk was broken.
A friend has one and claims if you squeeze the case it will work. He put a C clamp on his to make it work.
My wife teaches at a college and she said that other students have the same issue.
