8710w - fan works all the time - SOLVED

[marton225]

Hi,

I have same problem with my 8710w and F.20 BIOS.
I upgraded it yesterday from f.0B to F.20 BIOS, and now fan is always working on.
Could you share with me "equus.exe" file ?

My configuration:
OS Windows 7 64 Ultimate
CPU Core 2 duo T7700
nvidia quadro fx 1600m


Cheers

I have the same configuration and, except with my second display, it works fine.

@tiptaptop
Thank you for equus application.

@msk_sk
Thank you for this great guide!

I had just few errors while compiling dsdt.asl, which was due to expecting symbol '('".

Below is my situation; BEFORE changing data: TZ5_ varies between 50-70


and AFTER changing:


It is really quiet now, but it seems a little warmer then before new BIOS F.20
It could be useful if anyone have original dsdt.ASL parameters from BIOS F.0B, just to compare.

If I understand it well, I need to run "asl /loadtable dsdt.aml" after every fresh windows installation. Am I right?
Is there any way to change data permanently?

Could you export and post your regedit file:
HKEY_LOCAL_MACHINE\HARDWARE\ACPI\DSDT\HP____\nc65xx\00010000
And let us know, which version of BIOS do you have.

Then I extract and post the right DSDT temperatures for all of us.

Can´t download from dl.free.fr. Please upload elsewhere or send me reg file at msk_sk@yahoo.com

Thank you user tiptaptop for reg file.
But we need reg file from 8710w using other (lower) BIOS version than F.20

Hi, msk_sk,

I have attached the reg file from my HP 8710W with F.0E bios. I hope you can provide us the right temperatures. Best regards!

A reminder to anyone reading these fan issue threads... if this has been an issue with your laptop for more than a couple of years I highly recommend checking for lint buildup in the fan and fan enclosure.

My 8510w had always had a fan that seemed to work overtime but it eventually reached a point, after about two years, where it just ran constantly and temps seemed to be increasing. Since the fan runs on this machine more than is considered normal for most laptops it was accumulating dust/lint far more quickly than would be expected as a result. And I do not work in especially dirty or dusty environments.

I simply put a toothpick in the fan blades to keep them from rotating (spinning too fast) and applied light vacuum from a vacuum cleaner pulling in reverse of normal flow. An astonishing amount (seriously) of plugged up lint emerged and I had to remove it with tweezers through the fan grille and reapply the vacuum a couple more times to clean it thoroughly.

Huge improvement.
