Notebook frequently stops responding

Hello,

I've got a rather odd Problem on my Acer Travelmate 630.
JaS 10.4.7 is running quite fast and stable. I'd be really happy if it weren't for this annoying little snag... at frequent intervals - varying from 10 seconds to about a minute - trackpad and keyboard stop responding, the cursor vanishes and the computer freezes. I have to hit a key or touch the tochpad after a few seconds to bring the cursor back and have the computer resume whatever it's doing as if nothing had happened.

I had this issue with every single version from 10.4.3 to 10.4.7 but not on 10.4.1 which worked fine. Somehow my computer doesn't like 10.4.8 - it always boots into kernel stack errors, but that's a different matter (keeping my fingers crossed for a final 10.4.9 release which will miracoulusly fix everything;) ).

Does anyone know how to fix the freezing problem? I'm quite certain I'm not the only one who experienced this error.
I've tried everything, several versions of ApplePS2.kext, disabling PS2 completely and using USB mouse and keyboard (even genuine Apple), interchanging every single .kext that sounded fairly promising... up to pouring coffee all over the laptop, which wasn't entirely purposeful (fixed the rattling keyboard, though :D)

Anyway... I really hope there's someone out there who can help me. OSX seems to run so fine except for this damn freezing thing rendering it utterly useless.

Thanks in Advance

have u tried changing your power settings?
change it to never sleep/turn of monitor/hdd

also...did u install laptop power management pkg during install?

Thanks for your reply...

I've tried every single version of the PowerManagement Package I could lay my hands upon. None solved the problem though some prevented the computer from shutting down properly.

I'm not quite sure this is a Power issue. Somehow I've got a feeling that my problem has something to do with PS2. Or maybe with the IR/DA Port which isn't recognised by OSX but keeps flashing frequently nonetheless. Unfortunately Acer has crippled the BIOS to prevent disabling the IR/DA and it is soldered on the mainboard so I have no possibility to remove the thing from the system.

Could my problem be related to that? Or am I being stupid and it is something else?
Any comment or suggestion highly appreciated!

thats weird...i have an acer and it locks up and then i have to click or hit a button to get it back...and once i turned the sliders to NEVER in power management along with never turn the hard drive off and on second tab do not dim lcd...it hasnt happened.

i dont have IR/DA port so i honestly dont know if that could be the cause

but the power mgmt thing worked for me

I'll check the PowerManagement Dialog as soon as i get home from work.

Although I really can't imagine me missing to try that, I am suddenly in doubt.
I'll certainly give it a shot and report back.

Thanks for your support so far

...wish I had. It's a Pentium 4M 1.8 Ghz

Nothing has worked so far.

@xtreme571: could you perhaps tell me which version of PowerManagement.bundle you're using? Or even provide me with your version via PM? There seem to be severel modded versions out there...

im using the version included in 10.4.8 Intel SSE3 by JAS.

This was a re-release well atleast thats wat it said when i downloaded it

Once i get home i can see if i can get the bundle out of the dvd for ya
