Acer Aspire 5315s overheating
Does anyone know of a registry (or otherwise) hack to make the fan in an Acer come on full blast, all the time?
We're having a few issues with Acer Aspire 5315s overheating on Windows XP.
First, a little background. We have a load of 5315s - 15 for curriculum use and 8 or so staff "teacher laptops". They used to run Vista, but have now been downgraded to XP (which has significantly upgraded their performance and general reliability). The student ones are fine, but some of the teacher ones have developed what has come to be called "sudden laptop death syndrome", where they shut down without warning due to overheating and can't be restarted for a few minutes until the temperature drops.
I'm wondering if XP isn't controlling the fans properly???
Stuff we've tried with limited / no success:
:( Physically removing the back cover and removing a load of muck from the heatsink.
:( Updating the BIOS to the latest version in the hope it would give some heat-related options in there. It didn't.
:( Installing, amongst others, SpeedFan, which detect temperatures but can't find any fans to control |(I found a gadget to control the fan in an Acer Aspire One netbook - which produced some very strange temperature readings - maybe it's the thermal sensor rather than the fan that there's a problem with?? or maybe the drivers just don't match)
:( In Device Manager, there IS a device, reported as working properly (under system devices) named "ACPI Thermal zone" - but I'm not sure where to take that line of reasoning!
:( Installing the Vista "Empowering Technology" stuff - it installs OK but then doesn't work.
any ideas, anyone? if it was a desktop I'd have snipped the power cables to the fan and connected it straight to a spare HDD power connector from the PSU but I can't do that in a laptop... unless push REALLY comes to shove!:evil_twisted:
