Re: Fan runs at high speed after resuming from standby

I have encountered this behaviour on a few Acer laptops, TravelMate 6413 and
TravelMate 6463. I've got ALL the up-to-date chipset and device drivers from
Acer.
There are four ACPI temperature readings that I can find that are useful.
There's one for the HDD and each of the the Intel Cores. There is another
(for the GPU?) that normally varies with load, but after a standby/resume it
comes up with a fixed value, typically 27C for some reason. This fools the
system into running the fan at high speed.
Only if the machine is put under significant load does the temperature value
change: it suddenly goes from a constant value to varying with load again.

I've not had any such problems on a laptop with winxp..
Have you used only Acer updates for your drivers?
Tried updates from Acer for your chipset & other drivers.
Checked as to whether there is an Acer Bios update
If using AMD cool & quite checked AMD site?

I want to be able to put this laptop running XP in standby for a while
without this annoying fan behaviour on resume. What I'd really like to
know
is if anybody has had the same experience or if they know of a documented
known issue.
It is true that another manufacturer's laptop probably doesn't exhibit
this
problem, that I could shut it down instead of using standby. Unfortunately
much of my software and the drivers aren't yet compatible with Vista.

I have an Acer Travelmate 6460-series laptop. When I put it into standby
and
later (when it's cold) resume from standby, the fan runs at a high
speed
instead of varying with CPU temperature. If I place a great deal of
load
on
the processor, it eventually gets hot enough to reach a high enough
temperature threshold to slow the fan down. This only happens if the
laptop
has cooled down significantly since it was put into standby. If it's
still
warm, it varies as expected.
Acer tell me it's a known XP issue, but I've been unable to locate this
information through the various online self-help systems on the
Microsoft
websites. Is it more likely to be a BIOS issue?
To be honest, I have a laptop from 2002 that never had that problem but
it
isn't an Acer. It had original XP and was updated by me to SP1 then SP2.
None of that fan business at any stage.
Why not just shut it down when not in use or use hibernate instead?
BTW, if you have the capacity on that laptop (and I don't know that
laptop
at all) then you would prefer Vista. I have my new laptop set to "sleep"
when I close the lid. All closes down as if I turned it off and starts
where
I left it when I open the lid and does it perfectly every time. I have
found
Vista a lot better than XP in that way and also networking.
