Ram woes?

Maybe you guys can give me a clue.
In the last few weeks I've updated my G3 which has a G4/600 processor with a SATA 300gig HD. All is great. Drive is nice and quiet and now have plenty of room.
Here is my dilemna... I purchased some RAM from OWC (macsales.com). 3-256mb, added them in along with 1-256mb I already was using to bring the total from 512mb to a full gig. Anyway, programs are quitting (safari quits for no reason). Illustrator CS2 had issues opening, needless to say as I write this a simple 1.8mb dl via safari will not complete.
Any ideas? I ran TechTool and it said the memory passed the test. I ran Disk Utility and repaired permissions (no issues were found) and I booted from DiskWarrior 3.03.
The one thing I don't have is a 10.4.6 startup disk ( I have the 10.4 startup), any advice?
Thanks.

Does all of your RAM meet the specs in the developer notes:
>RAM DIMMs
The logic board has four 168-pin RAM expansion slots. At least one of the RAM expansion slots contains a factory installed SDRAM DIMM.
The RAM expansion slots accept SDRAM DIMMs that are 3.3 volt, unbuffered, 8-byte, non-parity, and PC-100 compliant. The speed of the SDRAM devices must be rated at 125 MHz (8 ns) or faster.
Lots of folks buy RAM that meets the PC100 part of the spec and ignore the 8 nsec part. It sometimes comes back to bite you. The best arbiter of whether you have the right RAM for your Mac is DIMM First Aid, a small free Mac OS 9 utility available here:

Intel mini RAM woes...

Ok, I'm pretty saavy when it comes to most things computer related but maybe I'm missing something on this one. I bought my Intel mini with the stock 512mb of RAM and decided I wanted to upgrade to 2gb. The price of RAM is fairly steep right now so I decided I would do this one stick at a time. I purchased my 1GB stick to get me going from Crucial (due to their reputation). I used their memory advisor to make sure I was ordering the correct memory for my machine and verified the memory matched what I ordered before it was installed. I installed the 1gb stick with one of the original 256mb sticks thinking I would maximize what I had available until I was able to purchase my second stick. After doing so I had nothing but problems. I kept getting spontaneous shutdowns and when booting up it would reboot itself sometimes 2 or 3 times before I could finally get to the desktop. So, I'm stumped. I've gone through and double checked that the memory was seated right, ran TechTool Pro 4, ran the Apple hardware test, reset my pram, reset my smc and even took out my 256mb stick to see if having an unmatched pair could be the issue. Everything looked fine and all tests passed. According to Crucial's website it is not "necessary" to have a pair of sticks in the mini to run properly. It even says I should be able to run different speeds and chip capacities. I was still getting the same result just the 1gb Crucial stick by itself. I have since put my 2 original 256mb sticks back in and all seems to be well. I know there is a possibility that I got a bad stick of RAM but I definitely have my doubts based on Crucial's reputation. I know how to handle computer components so I also highly doubt that I damaged the RAM. Is there something I'm missing? Do I need to have a matching pair of sticks (size and speed)? I'm racking my brain on this one, hopefully someone will be able to shed some light on my dilemma.

Okay, new problem... I'm starting to think now that maybe my RAM woes were not RAM woes at all. I'm beginning to think that perhaps I have a failing hard drive. Right away after purchasing my Mac mini I took the original 80GB hdd out and replaced it with a brand new 120GB 5400rpm Seagate hdd. I started having these random shutdown problems and then yesterday after having my new 2GB's of RAM installed for about a week or so (and working flawlessly), I got the screen that tells me that I need to hold down the power button to restart my computer. I do so and it goes to this terminal type screen and runs through all kinds of command lines. I restarted and desktop came back up so I did a couple software updates (1 Airport update, 1 Security update). After that finishes the mini restarts and it hangs at the grey screen w/the apple. So, I shut the computer down and restarted and this time it gets to the 'OS X starting up' screen and hangs when the status bar reaches the end. So, I shut it down and restart yet again. It goes on and on like this and finally ends up getting to the desktop after roughly 6 restarts. I quickly back up everything on my computer and try a few more restarts to see the progression of the problem and try to troubleshoot. At one point I heard the hard drive click 2 times. After another round of numerous restarts I get back to the desktop and by this time alot of my programs were getting the beachball when opened and would never function (i.e. - Disk Utility, System Profiler & Safari). I put my Mac mini OS X install disc in and restarted to wipe everything out and see if my OS got messed up somewhere along the way and was causing my problems. As soon as it boots from the disc I got an error box informing me that It cannot install the OS but allows me to access Disk Utility. I erased and did a 1X pass zero out. I restarted my machine and yet again it hanged at the grey screen with the apple. I restarted a couple more times and now it just tells me it can not install the OS and shuts itself down within a few seconds of this message.
So, this is where I'm at now... Can anyone else confirm that this sounds hard drive related vs. RAM related? The only variable that has changed recently has been the RAM and I refuse to believe that I got bad RAM twice in a row from a company as reputable as Crucial.
Help me AndyO, you're my only hope! (yes, that was a nerdy Star Wars reference)

Possible RAM woes!

Well..after posting a question about heat/sluggish performance..got a nice response from the Hatter. Among his many suggestions was to get copy of MemTester (or something like that..). Well, I did, and after I ran the program, the word "FAILURE!!" was scattered all over the report! Question is..does a "failure" report mean my whole bank (4X512) is bad?..or, does it take just one bad chip to earn that label. I'm thinking about taking out the two original Apple chips (about 5-6 years old) and seeing what kind of report I get with just 1 GB of new chips that I added last year. Good idea? If I decide to replace two chips, can I get a couple from OWC and mix them in with another brand? (same specs). By the way, after running initial test, I removed and reseated all memory, and got far fewer failure notices, but still enough to alarm me. Thoughts?? Thanks

You have to start testing and swapping. Can you mix? yes. But I would look at Crucial first.
http://www.crucial.com/mac/
Is there an address of where it fails? It only takes one DIMM of one chip to be bad. Go back to the other post and link to MacIntoch's BAD RAM report (I know it is long, but it is helpful in understanding what is happening).
After swapping and changing RAM configuration. reboot again into OF and reset-nvram as well. You should end up with memtest not reporting any problems hopefully!

RAM woes, so what did I buy?

OK Got a really good deal (2X1GB modules) from a friend but these don't seem to fit. Here is what's on their labels (yes they are used, but I practically got them free).
1). "Samsung 1GB 2Rx8 PC2-4200s-444-12-E3" The rest look like a serial number.
2). "1GB DDR 2 533 SODIMM" Again, more of a serial number thing afterwards.
Pulled the stock 512, and tried to put the Samsung in... It looked like the notch was off by only a mm to fit. =( Is this totally incompatible RAM? I haven't even the tried the second yet. Can you guys already tell by the type that they are not gonna work? If so, can any of you identify what I did get? Any one want them? =P
I have a suspicion that these are for the PB after my 1.33Ghz (1.5-1.67Ghz).

Can you recommend what RAM does work with the pre-2005 PBs? I'm looking to upgrade my RAM to 1Gb.
(Actually, I already did upgrade my RAM to some generic brand, but I note an increased heat & fan function ever since I did that.)
Samsung seems to get a good recommendation, but I'm not sure on its compatibility.

RE: G4 17" Aluminum (1.33 GHz) RAM Woes....

Hi Everybody!
I have a G4 17" Aluminum (1.33 GHz) with 512 MB in each slot. The one slot has Kingston RAM in it, and the other has, I believe, Hyundai RAM in it. I purchased a 1 GB DDR PC2700 333 MHz RAM chip (again, it was Kingston) and put it in the laptop. Here's what happened:
1. Computer totally locked up 3 consecutive times. So, I reversed the RAM chips.
2. Now the computer starts ands seems to run, albeit temporarily. Again more crashes.
3. I took out the 512 MB Kingston chip and replaced it with the other 512 MB chip, while leaving the 1GB chip where it was. Again, it would crash the computer or bring up UNIX script on my screen.
4. With the other 512 MB chip I now reversed its location with the 1GB chip. Same problem.
I thought Kingston RAM was supposed to be very good???
Has anybody else run into this problem?

There are 3 brands that work reliably, which are Kingston (as you found out, not their valueram line), Crucial, and Samsung. You can scan these discussions to see what others may work for people. Crucial and Kingston can be bought through their websites, or Kingston will link you to some online merchants who sell their memory. Samsung is sold through distributors, of which OWC is one at http://www.macsales.com , or you might be able to pick up locally. All carry lifetime warranties, and Crucial guarantees if you buy memory chosen throught their memory selector that it will work in your machine.
Possibly in the category of more than you want to know, the Apple architecture uses memory bus slewing, which helps to control battery usage and heat generation in the Powerbooks. This can present challenges to the memory itself, which is why some memory, while meeting Apple specs, won't work. You can google on 'powerbook bus slewing' to read the Apple developers note with more information.

K7D Master-L RAM Woes...

Hey MSI Crew,
Hope this posting finds you all well. I seem to be having a problem with my K7D Master-L MoBo that is driving me insane! Please help!
Here is the history of the problem (Sorry if it's long). I used to have a Tyan Tiger MPX dual CPU board. It had two AMD 2400+ CPUs, 1 GB of memory (ECC) and various cards (video, USB, sound). Well, one day I decide to open it to clean it. I had my air can and sprayed the dust away. I then pushed the power button and nothing. I then turned on the power from the back of the PSU and it started but no POST. Great... I fiddled with the board and no matter what I did, it would not pass POST. Blank screen.
What I realized started to happen was a flux of power on the board. You could hear the PSU rev up and down. I then replace the PSU. The new one is an ANTEC 550 BASIQ PLUS. Still no POST. Still reving.
I then go ahead and replace the Mobo. I got a MCI K7D Master-L. I put it into my box, attach everything and it runs steady. I had to get new memory because the sticks I had in the Tyan wouldn't fit. I got a Kingston 1GB 266MHz DDR Non-ECC CL2.5 DIMM PC-2100 ValueRAM. When it ran, everything worked: fans spinning, lights on CD/DVD-ROMs blinking BUT still no POST. Blank screen... Stripped down to basic and still no POST.
I then look at the D-Bracket lights and I see "Red Green Red Red". I look in the manual I downloaded from the MCI page and it states: "Memory Detection Test - Testing onboard memory size. The D-LED will hang if the memory module is damaged or not installed properly." It is brand new. I'm not sure if it is Registered or not. I do know the manual says that the MoBo requires: 184-PIN 2.5v DDR DIMM PC2100 DDR SDRAM (8 memory banks)."
I thought that this RAM was good enough. I have read on this forum that this board can be picky when it comes to RAM. PLEASE HELP! I really want this to work! Thanks everyone!

OK, so now I'm between and
I received the memory from Crucial yesterday and installed it into my K7D Master-L. I close my eyes, pray for a second, turn on the power and... nothing. It is still showing red green red red. No POST. This is what I've done so far:
*Cleared CMOS (Nothing)
*Change from 100 to 133 and back for memory (Nothing)
*Tried all slots for the memory (Nothing)
*Unplugged power supply so no juice was going to the computer and plugged it back and started (Same result)
The only thing now is that when I start the computer, I get a series of beeps (sporadic, not a real sequence) in the beginning and then becomes less as time goes by (a few seconds). I'm not sure if that's progress or not...
I don't know what else to do. I want to go from to Please help me!

Adding 2 GB RAM to MacPro (and SP3) Woes

I just added 2 - 1gb sticks to my mac pro running XP. XP shows 2 gb ram and Leopard shows 3 gb ram. Is there a reason Leopard only shows three and how do I *actually get* XP to show more than 2 gb (other than being sent to ms help pages).
Also, I get a "Service Pack 3 Setup Error" when I try and update:
"There is not enough disk space on C:\\WINDOWS\$NtServicePackUninstall$ to install Service Pack 3. Setup requires a minimum of 4 additional megabytes of free space or if you also want to archive the files for uninstallation, Setup requires 4 additional megabytes of free space. Free additional space on your hard disk and then try again."
There's 288 gb of space on my hard drive.
I don't know if any of these are related but I also get a 0KB showing for the download for this update.
I'd call Apple Help on this but I'll end up arguing with them about why I feel like I got the bait and switch when I bought my MacPro with 16 GB of ram space to run XP.
Many thanks,
Jonathan

Hi Jonathan,
with OSX Leopard you should get the full amount of RAM that is installed in your Mac Pro.
If not it could either be that the modules are not properly seated or are defect.
Try moving the modules around in the slots and also use the Apple Hardware Test (the extended tests) that is on the OSX Leopard DVD that came with your MP.
Insert the OSX DVD in your MP and restart while holding down the 'D'-key.
32-bit Windows (XP and Vista) can only see/use 2GB of RAM. That is common with the Mac Pro.
Only with Vista 64-bit (or Windows 7 64-bit) you will get the full amount of RAM.
A for the SP3 error, it's a coomon error that surfaces sometimes.
See here for solution http://www.windowsreference.com/general/error-there-is-not-enough-disk-space-whe n-installing-sp3/
Also you should download the SP3 stand-alone update while you are in Windows.
And also the BCUpdate 2.1 Driver package from Apple Downloads
Hope it helps
Stefan

Continual Mac woes (no question, just a rant)

It's Tuesday, and I am having terrible problems with my Mac. But then, why should Tuesday be different from any other day of the week.
Here is a typical day for me. The computer appears to be working OK. I need to watch a DVD for my work. I turn on DVD player, and put one in. The machine can't read the disc. It clicks and whirls, but the icon does not show up on the desktop. Meanwhile, so distressed is the machine that it freaks out. What was up until now was a fluidly operating machine suddenly reverts back to its old ways (i.e., its ways of two days ago). The hold ups and spinning pinwheels begin to eat of hours of my work day. (Remember the old days when computers made life easier?) The machine becomes sticky, gummy. Oh, I can move the curser and it seems to work for a second but then gets stuck in the dock, which explodes in icons and then freezes for five minutes. Yes. Five minutes.
Would love to use Force Quit, but the cursor is spinning, and nothing is responding. Funny about that old Mac. You can't force quit Force Quit. I guess I need to leave it open all the time.
Of course, FQ usually works on Safari. I have never just "quit" Safari. It always requires Force Quit, otherwise I can't turn off my computer. It stalls shut down.
Now I have a DVD trapped in there and can't get it out. [But I just got an answer from another posting.]
In the old macs, there used to be a pin hole you could stick a needle into ... can't find one on my flatpanel iMac.
I bought my Apple flat panel iMac in August of 2002. Yes, I know that that is a long time to have a computer, but I am not rich nor attached to a corporation that can splurge on computers. The first weekend I had the machine, I had three kernal panics.
Among the other problems I have documented are the following: the dock hiding itself unbidden and other features checking and unchecking themselves (Aug 2002); bus errors connected with OS 9 (Sept); some problems that inspired the tech person (Eric)) to talk me through deleting my user i.d., resulting in the loss of two months worth of e-mail (Thursday, 12 September); Preview problems (September); a bizarre box with an unmovable and undeletable red stop sign in it that no tech person or other Mac user I know had ever hear of (Monday 30 September); printing problems; computer won't shut down, numerous disconnection errors, which turned out to be caused by an OS X update (beginning December, 2002, or later); Kernel panics (Feb); computer won't shut down (March); Faxstexx problems, program won't allow me to set it up, finally just deleted the software (April); keys like "V" freeze and repeat endlessly (May 21); DVD Player freezes (May); Safari and Mail begin quitting unexpectedly (May); cursor begins to blink and fade out, plus odd sounds come out of the speakers, a constant error beeping (Sept 9); DVD Player problems (Oct 4).
I called AppleCare while I had it about once a week (the total between August 2002 and the time it ran out was about 155 calls). Naturally, some of these calls are motivated by user error. On the other hand, many of the issues I have called about were unprecedented as far as the Tech person was concerned, such as the blinking mouse, the red stop sign, and the DVD Player woes.
Things improved with Panther, but in Tiger many of the same old issues have returned.
I have been having so many problems with my Mac that I once wrote a letter to the company asking when do I qualify for a new replacement machine. I never received an answer, but I felt better for about a day. Then I turned on my Mac again.

The spinning ball of death as we used to call it is often caused by a lack of RAM, it is hard to be sure as I am not working on your machine, but sometimes things can be improved with additional RAM, it makes it seem like a whole new computer.
A lot of your problems sound like stuff that can be fixed easily enough, and although frustrating things happen here and there with updates. It sounds like you are in fairly good spirits with it all, I would suggest just researching a bit more into maintenance you can do to help maintain the computer and educate yourself a bit more (sounds like you already have learned quite a bit along the way) and you will find a lot of these issues take you a few seconds to rid yourself of. I would start by making sure you are repairing permissions regularly and running the most up to date software. If a lot of problems persist, try creating a second user that is a "test" user to see if the problem is replicated on that user (don't delete your other one, but if you do find the problem not on the other user, you might have a corrupt user, however you don't have to lose all your emails there are plenty of ways to back it up and import it in, or even just bring the entire Mail folder from your library over to the new user). Another thing you can do if you find a lot of system problems is archive and install the OS, it takes a bit of time, but doing it overnight shouldn't be an issue, and you won't lose any of your stuff.

Hp Warranty Woes & Hard Drive Heartache

HP – Warranties Woes & Hard Drive Headaches.
Dear Internet Community (I.C)
I need your help.
I would like to know if I’m being unreasonable in my expectations or is Hewlett Packard (HP) not living up to its both moral & legal obligations as a good corporate citizen & what it alleges to be – a Customer Focused Global Computer Services company.
Apologies if this is a little long winded but in the interests of fairness I need to put as many HP comments in as possible – to give you a clear picture.
So bear with me, you will not be disappointed & there are a couple of questions you might like to answer & feedback to the appropriate parties.
Keep in mind at all times we are talking about approximately a $200 (NZD) fix – less than the lost profit on one lost sale for an HP PC ( you might think twice about HP products after reading this).
There are two parts to this problem :
Part 1 :
I purchased an HP Touch Smart a few years ago, I registered the product & warranty with them & over the years have received have received numerous emails stating “buy this, upgrade now”.
But I don’t recall ever receiving an “WARNING – Critical Failure Issue (CFI) apply attached patch immediately” email while under warranty. Why is this relevant?
Ø Seagate makes Hard Drives – in this case a Barracuda 7200.11
Ø HP buys said HD’s from Seagate
Ø Seagate finds a problem with firmware in HD’s & advises HP & supplies a fix
Ø HP knows which Customers have these HD’s, because you know what goes into your machines – right ? - see below
Ø HP FAILS to send email to Customers with the fix (a simple email with attachment would solve problem) or issue recall.
Ø HP even offers previously to fix problem FOC & puts fix on its Website - but only if the Customer knows somehow of the problem.
Ø Should the Customer intuitively& telepathically know of problems in HP Products in advance before it fails, because of course HP is not telling their Customers.
Problem or Outcome: My HD has bricked itself & will not operate as I never received notice of the firmware fix at any time either in or out of warranty.
Paul Boshoff - G M -Personal Systems Group- HP NZ (PB- GMPSG) says
“It would be very difficult, if not impossible, for any computer vendor to proactively notify it’s customers of component-level updates”
“Failures of the kind you’ve experienced are usually related to a specific batch of serial numbers and often those component serial numbers aren’t available when the user is registering that particular computer.”
Now let me know if you think I’m wrong, but it sounds like HP does not know what goes into its machines or at the very minimum does not keep track of this.
HP, a Global Computer Services company cannot possibly be expected to track what goes into its machines. HP apparently does not record or match the serial number of the HD with the machine it goes into.
If Ford & Toyota can track & record what tyres go on which make & model of their cars which are in the millions each year & can recall cars dating back 8-10 years just case of a manufacturers component malfunction why can’t HP link & record the HD details.
I can just hear it now “I’m sorry we don’t know which engine we put in your car”.
And let’s be real clear here – we are not talking about some small screw at the back of a PC – Along with the CPU & the RAM, the Hard Drive is pretty much up there in the top 3 of important components of any computer.
I.C – Do you feel
ü That fills you with confidence in HP products & services ?
ü Should HP be required to tell its customer of CFI’s with its products – particularly while under warranty?
ü Has HP tried to limit their liability & cost by directly NOT telling Customers of CFI’s while under warranty?
Part 2 :
When your HD bricks itself – apparently all is not lost – some very clever person has found a solution so you can get the HD going long enough to apply the firmware fix & then your HD is a good as new – Here is the link that spells it out with pics http://www.overclock.net/t/457286/seagate-bricked-firmware-drive-fix-with-pics)
You’ll see the relevance of this shortly.
After much messing about I received the following email from PB- GMPSG : “I have escalated your issue and have just received the go-ahead to repair your unit at our cost. We will be utilizing our own, authorized service provider to re-install the original hard-drive and to run the software fix on that unit.” (This guy most likely earns a six figure salary & isn’t able to sign off $200 fix).
NOTE : it does not limit or restrict what type of fixes will be used & also at this time HP was aware of both the Seagate fix & above fix.
I delivered the PC & bricked HD into the HP Authorised Repair Centre (ARC) as requested –their ticket instructions read “do firmware update…HP to incur costs. NO COST to customer”.
Obviously it’s not rocket science but you need the HD going before you can apply any firmware fix including this one – HP knew that to get the HD going they would need a special fix to enable them to apply the Seagate fix.
After all this is not an isolated case & I did point out to HP that they would need the fix I supplied (or something similar HP approved or designed if that made them more comfortable) prior to their offer of fixing the HD.
HP said their ARC’s had all the right software for fixing their machines. In addition I have been told on several occasions, the ARC’s are the bee’s knees, the cat pajamas, the whiz kids of the PC service world “The first port of call for the repair centre agent is to download all the latest service advisory notices and updates. This is a very fundamental part of the repair process and one that we spend a great deal of time emphasizing with our authorised repair centres” Keep this in mind.
A week later I received a call from Peter Gasporaratos, HP CS Melbourne (poor guy – caught in the middle) & stated “there is nothing else we can do for you”. When I asked if they had applied the fix he said “its not our responsibility.. its not part of our guidelines.. the ARC does not practice unauthorised methods..& this ARC will not go down this path”
Ironically the day before, Barry from the ARC said “we can attempt it, but we will charge you too”. So HP’s own ARC will do it, but there will be a cost – but hang on a minute, didn’t PB- GMPSG say “to repair your unit at our cost. We will be utilizing our own, authorized service provider to re-install the original hard-drive and to run the software fix on that unit” & HP CS put on the instructions “HP to incur costs. NO COST to customer”.
I.C – Do you feel
ü HP have said they will fix it at NO COST to me, regardless of what the fix entails ?
ü Should HP honour this commitment ?
ü Would you do business with a company that says one thing & does another & does not honour its commitment ?
ü That given the bricking fault did not need to happen if HP had been proactive in letting their customers know of the firmware issue & this is not an isolated case– shouldn’t they then be responsible in finding or developing a fix for getting the HD going long enough to apply the firmware fix if they are not going to use other recognised fixes.
Abstract
So that’s it – what do you think I.C. ?
Would you want HP computers & servers controlling the Traffic Lights, Air Traffic Control, Patient records & Medications at Hospitals knowing that HP will not tell these organisations that there is CFI with their products & they could suddenly lose everything. All dead while they try to find a back up computer with all the data – god forbid if President Obama’s “football” is powered by an HP – Nuclear War before we know it.
But seriously – I would love your feedback – Am I being unreasonable in asking them to honour their commitment for a $200 fix ?
And of course HP being a Customer Focused Global Computer Services company, would welcome your feedback.
Here are a couple of the players contact details who would love to hear from you :
ü Keith Watson – CEO –HP NZ -I initially contacted him & he thanked me for bringing it to his attention, then nothing.
Email : [email protected]
ü Paul Boshoff - G M -Personal Systems Group- HP NZ – well of course you now know who he is now – he would love feedback.
Email : [email protected]
ü Jessica Rangi – She’s the Spokes person/PR/Marketing for HP NZ & has just help launch HP new PC range in NZ – She would love your feedback as it might impact on her marketing & she is quoted as having helped out in warranty situations before & has worked at HP head office.
Email : [email protected]
ü Meg Whitman - President and Chief Executive Officer of HP Global
Email : [email protected]
They would all like to hear from you J
I.C
J Thanks for being patience & reading through to the end – now it’s up to you
L buy HP Products & Services or not.
L Do HP deserve your hard earned money if you now believe they aren’t going tell you about problems with their Product & Services.
Be kind to one another & take care.
Regards
Smithie
P.S - I sent this blog to HP for fact & quote checking prior to uploading (I gave them over a week to reply) – the silence was deafening from HP.

When requesting assistance, please provide the complete model name and product number of the HP computer in question. HP/Compaq makes thousands of models of computers. Without this information it may be difficult or impossible to assist you in resolving your issue.
The above requested information can be found on the bottom of your computer or inside the battery compartment. Please do not include your serial number. Please enter the model/product information into HP's Online Consumer Support page and post it here for our review.
I doubt the hard drive would be covered by buying an extended warranty after the fact. There is also no reason to buy a new hard drive from HP. Almost any 2.5" hard drive on the market will work in your computer. You will need your personal HP Recovery Disc set to return the computer to a factory like state. If you didn't create these discs, you will need to order a set.

LEOPARD 10.5.1 - Macbook Pro 15" 2.4GHz 4GB ram - crashing, doesn't wake up

I've 2.4GHz 15" Macbook Pro with 4GB RAM and latest 10.5.1 LEOPARD. I'm getting very upset about the LEOPARD as it's not stable at all compared to Tiger. I've frequent crashes, see photo below.
As described in other topics on this forum, i have simultaneous problem with the laptop not waking up from a sleep mode. The screen is black and the keybord and poer button is unresponsive. I have to hold he power button to FORCE-shut down the computer.
I've done clean LEOPARD installation, not an upgrade.
LEOPARD is getting a lot of unwanted attention with all it's flaws - just google for it.
I was imagining that apple is working hard on this problem, but over the time i'm getting tired of this and although i love the new features i need a stable system - that's why i have MAC and windows!

It looks/sounds to me as if you have a problem with the "Hall Effect" switch which activates sleep when the computer is closed, MarukoDT.
THis isn't actually in the hinge, but is activated by a magnet in the lid when the computer is closed.
"Sleep Cause 5" is certainly closing the lid on my MBP under OSX 10.6.2.
In fact you can reproduce symptoms very similar to yours by simply placing an MBP13 on top of an older Polycarbonate MacBook. If you do this then the magnet in the MacBook activates the Hall effect switch in the MBP13 even when the MBP13's lid is open. Simply moving the computer off the MB will immediately allow it to wake. (see http://support.apple.com/kb/TS2917 for the Apple KB item on the matter. I've done this myself when sharing a power adaptor and was about to launch in to major "troubleshooting mode" when I remembered having read this article a few days earlier! )
So, assuming you don't have your MBP stacked on top of an MB, and don't work on top of of an MRI machine or other things with substantial magnets , I'd be thinking that it is a defective Hall Effect switch itself that is causing your woes. If so, it is a workshop warranty repair, I'm afraid.
(There are many other possible causes of sleep problems. Generally they involve issues with third party software or third party hardware, but your case is different. I no longer have the log files from my own accidental experiences of this when sitting the MBP on the MB, but from memory they actually looked very like yours.)

Do I need to look at machines with 16 GB RAM?

I am interested in purchasing a 13" Macbook Air as a replacement for my current 13" mid-2009 Macbook pro. I have vacillated between the MBA or the retina-MBP for some time but really want something portable. My only reservation is the RAM of the MBA. I know it is not upgradable and you can only get it with 8GB.
My current MBP is 2.53 GHz Intel Core 2 Duo appears to be using most of my current 8 GB of RAM as shown by the Activity Monitor report below. I plan to use the MBA for the same activiities as I currently use the MBP and allow for any future needs as I tend to keep my laptops longer than the average 3 years.
I tend to multi-task on my computer with internet, itunes, iphoto, excel, word processing but do not do any video processing or gaming.
Would 8 GB RAM be enough or should I consider an option (rMBP) where I can upgrade to 16 GB?
Thanks in advance and Happy Holidays.

The high memory usage you are seeing is probably due to having large programs open simultaneously, such as Excel and Woed and iPhot...things that use a lot of memory. If it is important to keep them all open at the same time, then more memory will be of help, especially since that will reduce the use of virtual memory, aka the hard drive, which is slow memory.
In this type of usage, a machine that can handle larger memory installs may be a good choice.

Mixing RAM Modules

Several weeks ago, I replaced my 256 MB RAMs with 2 1 GB modules in a late 2005 G5. They seemed to work fine, though my GPU seemed to be running a bit hotter. I just installed an additional 2 GB bought from OWC, and also added back the 2 original 256 MBs to bring my total to 4.5.
Looking in System Profiler, I see that my original 256s and the latest 1 GB modules are PC2-4200U-444, as specified in the online compatibility guide. I see the I GB modules from my first upgrade are PC2-3200U-288.
I bought them at a local shop- for way too much money, by the way - and was told that the number printed on them was wrong and they were compatible with my model. Is that right, or this a problem?
Thanks

Hi! The PC2-4200 modules are the correct ones and you shouldn't run anything slower. You can run faster ones but you shouldn't run slower ones or mix speeds. And if the computer sees them as the slower ones then most likely they are! Tom

Mixing RAM Modules (1gig + 2gig = 3gig)

Hello,
I am about to buy a Mac Mini and I am on a tight budget. The one thing I want to do for sure is upgrade the memory, but I'm in a quandary of sorts given my budget. The retailer where I want to buy the Mini from only sells the appropriate RAM for the Mini in 2gig modules. So here's my question: I know it is possible to mix the stock 1gig stick with a 2gig stick to get 3 gig of RAM total, but will it be worth it to me? I realize that the best configuration would be to slap in 2 2gig modules in and just be done with it, but with 3gig, would I be appreciatively shooting myself in the foot and killing the machine's performance, or wouldn't I notice? I need to have the memory installed at purchase because I am physically handicapped and adding the memory myself is out of the question. And after researching how to replace memory on the Mini, I wouldn't have the courage to ask anybody I know to attempt to do it after buying it. Is mixing RAM modules a good idea?
Thanks in advance.
Malcolm

Nope, I am not confused, There does have generation between Mac mini model. Maybe not official, but we all know. Check About This Mac ---> More Info ---> Model Identifier : Macmini2,1 (That means, 2nd generation)
Macmini 3,x (means 3rd generation I supposed)
And the 3rd generation doesn't support Dual Channel, referred to Crucial.com

Mixing RAM modules on a 800Mhz machine

I have a new Mac Pro. 800Mhz. I want to install more memory but n find any 800Mhz 2Gb modules for sale as yet.
I have the option of installing 667mhz modules.
Will this cause a problem mixing 800Mhz and 667Mhz modules?

You posted your question in the wrong forum. This forum is for pre-G3 Macs. You should repost in the Power Mac G5 forums @ http://discussions.apple.com/category.jspa?categoryID=108
That said, this will probably answr your question.
You can't use a processor speed lower (667Mhz) than that specified (800Mhz). Plus there are other restrictions. See *How do you upgrade the RAM in the Mac Pro? How much RAM of what type does it support?*
@ http://www.everymac.com/systems/apple/mac_pro/faq/mac-pro-how-to-upgrade-memory- what-type-ram.html
You can buy the 800Mhz RAM at Other World Computing @ http://eshop.macsales.com/Search/Search.cfm?Ne=5000&Ntt=MacPro+800MHz+MatchedPair&Ntk=Primary&Ns=P_Popularity%7C1&N=7318

I have a brand new MacBook Air 11 inch, 4gb RAM and 256 gb SSD where the screen flickered abnormally and got dead all of a sudden while uploading a photograph in FB. Can anybody help?

I have a new MacBook Air 11 inch, 4gb RAM, 256 SSD and use Mavericks OS. It is still under waranty period.
Just few days ago while I was uploading a photograph in facebook, the screen started flickering abnoromally. I tried using the escape button but nothing was working so switched off by pressing the power button.
After few minutes I tried to switch it on but my system never waked up. Called up the Apple Support, did SMC and PRAM but nothing worked. Then I was advised to take it to Apple's authorised service centre.
At the service centre the engineers diagnoised and then said that the MLB/mother board needs to be replaced. Had waited for six-long days and today they had replaced the MLB/mother board. Now, the system came to life but nothing has booted. The screen goes white and a '?' question mark icon keeps on flickering.
After thoroughly diagnoising it the engineer said that now the problem is with the SSD and the worse thing is all my important documents and photographs etc are no more there. And I don't have a backup of the same!
While Apple Support contact centre is assuring they would replace any other parts if found faulty, but I feel differently. First, the MLB/mother board was changed now they say it is SSD problem - so if the SSD too is replaced there are possibilities of more faults coming up. All I can see and feel that this particular machine has turned out to be architectually deffective that calls for immediate replacement.
Right now I am using a friend's windows pc to write this mail.
Feeling completely miserable - all my expectatations gone after investing in such an expensive machine, loss of all my data, wastage of time and energy and to top it all affecting my daily work.
Can anybody please advise what shall I do?

Take the system to an Apple store to be fixed or replaced as the one you have has defective hardware.

Ram woes?
