Overheating 12" Rev A Powerbook

Message #1 - Posted 2005/03/26 - Chris

I've just updated my Rev A 12" Powerbook with the latest Apple Security update (late March 05) and my old overheating problems are back.

Has anyone else encountered this? If so, any suggestions for a solution?

Thanks
Chris.

Not much help but no change here, or only a very small one, on my Rev A 12" with all updates.

What is the overheating problem? Is it more than the fan kicking in noisily?

Only slightly related, but my PBoko 12",, a 1.33 (home contents insurance replacement of my original rev A) hardly ever starts the fan... on the older one it was on practically all the time....

I have applied the security update on my TiBook 1GHz, and since then the fan is on almost 100% of the time. It cannot be heat, because I sit the laptop on a small (and incredibly silent) pad that has two large fans blowing air up over it. Yet, since the update, the fan just chugs away all the time, making quite a noise. I am tempted to reinstall as I like silence with my computers.

Grrrrr!

Thanks for the response - the situation seems to be that the area under the left hand rest (Hard Disk) is heating up far more than it has for quite some time. This is causing the fan to turn on for most of the time the laptop is powered. The wrist rest is quite hot to touch and I've seen some degree of slow down in performance.

I'll check the temp using the tool you suggest and report back.

Chris.

This sounds as though the upgrade is leading to an increase in HD useage- which is perfectly possible. Where I'm dubious about this is that it could surely only apply is the HD spins down in normal use; does it?

maybe dumb but have you checked the power settings havn't been ajusted? at least check they are set to what they should be, incase they have been ajusted by this update? why they should i don't know but its worth having a look at the prefs any way.
