Getting HP ProBook 4530s silent, maybe DSDT patching?

[N00b-un-2]

I thought maybe it is possible by doing a DSDT patch, but I don't know where to start here.

HP 4530S...
DSDT patching...

Ubuntu != OSX

There is no equivalent to dropping a modified DSDT.aml into /Extra on Linux. The only reason such workarounds exist on that other OS is because that functionality is purposefully built in to the Chameleon boot loader.

I read the script fanslow.sh. You did a great job !

On my ProBook 4330s, I am using "/sys/class/hwmon/hwmon1/device/temp1_input" instead of "sensors", it seems to cost less cpu.

Hi pieceofcake,
you're right.

for those who receive a cpu temp value by running "tail /sys/class/hwmon/hwmon1/device/temp1_input | cut -b1-2", you can change line 28 of fanslow.sh:

#from:
TMP=$(sensors | grep Physical | cut -b 18-19)

#to
TMP=$(tail /sys/class/hwmon/hwmon1/device/temp1_input | cut -b1-2)

happy silent new year

So how silent or loud is the fan under normal load (web surfing, office apps...)? Can you adjust temps and fanspeed (e.g. make it switch at 50C?)
Thanks!

hi vickoxy,

i'm using ubuntu 12.04 on my probook 4530s for several month now. With my FanControl-Script, your system will be as silent as you hard drive is. It means: the fan will be off under 55°C. (If you're using a SSD your system will be noiseless!)

You can configure your temperatures by youself. I would recommend my settings like i distributed them in my dropbox link. Please set the setting "Fan always on on AC" to off in your system bios to gain full noise reduction.

I've got a HD3000 and a Radeon 6490M grafics card in my probook. if you're using a similar system, please make sure, you've got the driver installed and set the integrated grafic.

Need help here. I bought actually one Hp 2540p. And no pwm fancontrol. But i tried scripts (.sh) posted here, and they are partially working.
E.g.

sudo ./probook_ec.pl FANOFF

really stops the fan for few seconds, or even

sudo ./fanslow.sh

but how to manipulate with the data there, and make the compute to hold to it?
E.g. i would like to have Fan off until 60 Degrees. No idea what should i change to those files to make it working...

Help me please-don´t want to sell the laptop. And the progress is here-the fan is respnding to those .sh files, but it doesnt stick very long to it...

No one?

3 posts in 15 hours? It's weekend.
Try setting 'Fan always on on AC' to Off in BIOS.
the temps can be adjusted in fanslow.sh , look for value 55, this is the first step.

I did that (BIOS)-no change at all.
So, if i change value 55 to 65 (if thats Celsius) and run fanslow.sh, the fan stops for 3-4 sec. and then starts again-although the temperatures are not higher as 45-47 degrees.

linux@linux:~/4530s/FanControl$ sudo ./fanslow.sh
0:80:180:65
0:80:180:70
0:80:180:75

I tried to change other values too, but no change in fan behaviour-the script stops the fan only for few seconds...

Weekend-my days off-meaning i am trying to fix the computer...
