So my laptop - 4+ year old 15" MacBook Pro - has taken to shutting down under high memory/high cpu conditions.

Nothing is logged, it just powers off.

I've run Memtest on it for a number of cycles and it comes up clean.

I figure that either:
A) Memtest is wrong and there's a bad memory spot that only gets hit occasionally
B) There are thermal problems.
C) I have no other ideas.

Any opinions from the crowd?
(I'd love a resounding "It's the memory!" as getting to the heatsink to re-thermal-paste this is a challenge", but I'm not expecting it.)

As I don't know if it's actually going to help me (http://supportdb.alsoft.com:591/FMPro?-db=alsoftsupport&-lay=main&-max=15&-format=AlsoftSupport-qa.html&-script=counter&-token=183&-Skip=96&-find ) I'm reluctant to buy it outright.

If it works, I'll pick up a copy after...

In reply to my earlier post, [livejournal.com profile] en_ki asked:
> Did you do the PMU reset dance and the OpenFirmware reset dance?

To which I replied:
Repeatedly (for the 1st).

It never worked... untill I tried again this evening.

It's up. It's running Tiger, as I can't find my Snow Leopard media right now, but it's up.
(and it's got the new drive in it!)
We'll see if it stays that way.

So, yeah, it's working right now. YAY!
Let's hope things continue this way.
I still want to know where to get the yellow cable tape, and what its special properties are (Non-static, I presume. Non-melty, too. Anything else?)

So, I come home tonight and joke to Laurie: so, I've sone nothing different, will I get a different result?

We laugh and I try anyway. It chimes and the backlight comes on. We are amused and bemused. Sadly, that's all it does, and that only once. Nex time it's dark and silent again.

This sound familiar to anyone? Also, where do you get the yellow cable tape they use inside laptops?

So, the disk swap was easy enough... Except now the machine doesn't boot and there's no evidence the kb is being read. It gets power - and passes it all the way through the chain of everything I touched - from the power switch in the top half of the case, through the same cable that connects the keyboard to the mb, through to the disk cable ( the disk spins) to the led on the front, which is connected through the disk cable, too.

But there's no power-on chime, the back light doesn't, and there's no sign of any non-backlit anything on the screen. Holding 'c' or the trackpad button doesn't do anything with the optical drive, either booting from it or ejecting it.

God damn it.

I'm becoming more and more convinced that I have a failing disk in my 3.5yo MBP.
I know that opening the thing up involves a spudger and many small plastic tabs between the top and the main body of the beast.

Anyone local to me done this before and want to provide some moral support as I do it?

(Why I believe something is failing...
SMART tests are NOT coming up with errors, but various things cause a fair number of
3/20/10 2:09:39 PM kernel disk0s2: I/O error.
to be logged.
I've not gotten a good Time Machine backup in quite a while. I'm getting:
3/20/10 1:59:42 PM com.apple.backupd[20269] Error: (-36) SrcErr:YES Copying /Path/to/file to (null)
(-36 is IO err) and then it fails out after a heap of them.
