Debian Hardware :: Lm-sensors On Dell Studio 1557 - Thermal Zone Jumps Up Quickly
Feb 23, 2010
I just got a dell studio 1557 with core i7 processor. I have heard they run warm and suspect this one is no exception but am having a hard time monitoring the temps. When doing acpi -V i can see 2 thermal zones (0,1) with the first being 63C and the second always staying 26.8C. When I am doing a lot of processing the first thermal zone jumps up quickly. First, should that be the processor temp? Secondly, any way to get more accurate readings with lm-sensors(sensors-detect can find no monitoring items).
I originally installed Kubuntu 7.10 on an ACER laptop (exact model escapes me at the moment) and subsequently upgraded to 9.10 and then to 10.04. Starting with 9.10, I had problems with the computer suddenly turning off in the middle of doing work. Eventually, I figured out that when this happened, the bottom panel had gotten quite warm so it probably a thermal control measure. Further, I discovered that I could prevent this by setting the power regulator to powersave, which effectively kept frequency scaling at 50% and under which I never had the computer suddenly turn, the only exceptions being when unplugged the computer and replugged it in and it would switch to dynamic power policy thus running at full power.
However, after "upgrading" to 10.04, I can't do anything to restrict frequency scaling. Whether I set the regulator to powersave, ondemand or anything, CPU frequency can go to full capacity until it heats the CPU to the critical trip point, invoking poweroff. Sometimes, this would happen just a few minutes after "acpi -t" reported 40C (is there some way to test the output from acpi, I've seen it report obviously wrong figures such as 0C when the room was considerably above freezing?). While trying to figure out what to do, I discovered the /proc/acpi/thermal directory and subsequently the /sys/dev/... directory.
I would like to know which directory I should focus on and what files in order to establish trip points and direct actions that will force the system to reduce heating so it won't reach critical. It's not like it's particularly compute intensive tasks triggering this. I have had it happen while running nothing more than the windowing system, system monitor, terminal and paging through a file with less. I have looked for documentation online but have not found anything that clearly explains what I need to do. The only parts I understand from what I've found are "[critical]: S5", "[active]", and "[passive]". The "[passive]" line included items like "tc=..." and "device=0x...", but I have no idea whatsoever what any of those settings do and the documents do absolutely nothing to explain them.
1) what file I need to edit, 2) what options I can set in the file, 3) what values those options can take and 4) what effects those values have on ACPI's behavior. Lastly, the default setting HAVE GOT TO BE CHANGED. Having poweroff as the first line of defense against overheating is simply UNACCEPTABLE. What would happen if this occurs during the middle of a system upgrade? I know at least enough to figure what needs to be done, even if I can't figure out how to do it. Many users can't even do that and I don't think they should have to. The installation process should automatically detect what methods of reducing thermal output available (reducing frequency scaling, throttling, fans) and set trip points that invoke them before reaching critical.
It's only been a couple of days since I formatted my toshiba laptop's hard drive (i was running fedora without significant problems) and installed slackware 13.1 32bit. I did a network install because the dvd drive is not functioning properly. everything installed fine with the hugesmp kernel, but I started not being able to boot the laptop every single time I wanted to (especially after a reboot but also after a power up).
my observations:
-the pc might freeze in the very first toshiba logo screen (where you are prompted to press F2 to enter BIOS)
-or it might freeze when I get the lilo boot loader (not even the count down to choose kernel starts) - but i CAN use the arrows and press 'enter' to choose to load a kernel manually
-or just after it loads the kernel and the bios checks
-or during boot after in loads ACPI thermal zone
-or a little later during boot when the dhcpcd if broadcasting for a dhcp lease.
the first 3 are freezes, the last 2 are resets. especially if i need to reboot (or get the resets of the 2 last case), I will surely get stack in one of the first 3 cases afterwards! i have observed that rarely, after such a reset, if it actually gets stack in the toshiba logo, i might be able - pressing the poiwer buttonj repeatedly to actually overcome the 'freezing' there at which time i'll get to the lilo loader (the count down timer will not.. count down), but i can press 'enter' and I will finally get stack after loading the kernel and bios checks
So I have to powerdown the laptop and start all over again. Sometimes the whole boot process will proceed smoothly. and i'll get to a login prompt, and when I do I can keep the laptop up and running for virtually ever. that is it doesn't seem to be slackware related... Hwever the problems started after I installed slackware. I didn't have any problem with the fedora installation and i wonder if it has something to do with the network boot.... additional note, with feodra i didn't have a problem restarting or shutting down the laptop. now if i restart, the pc will go through the process of shutting down, but it will never actually reboot - i'll have to do it manually..
I recently assembled a Dell T5400 workstation. I'm getting some strange issues with this machine concerning fan controller.
-Only 2/4 motherboard fans are detected. All fans have RPM signal -The only sensors that are reporting temperatures are for the memory modules,graphic card and disk but not from my Intel CPU's. This chip reports memory module temperatures as they tend to get pretty hot (DDR2-FBDIMM). -Every time a fan speed gets reported with sensors command the bus freezes for a moment. Videos playback and audio chops for a moment and continue normally.
After removing module dell_smm_hwmon the sensors command executed without interrupting multimedia flow but no fan speeds were reported also.
As a temp solution I blacklisted the dell_smm_hwmon module and I solved the high fan noise problems and the bus freeze.
As it turns out i8k module for fan control is very buggy for some DELL models. Can I manually configure it somehow to work?
So to sum up the problems my problems are:
No CPU temperatures reporting. 2 Fans Speed and PWM controller info missing, and freezing the bus when probing to get speeds from those identified (dell_smm_hwmon module issues).
The object is to get fancontrol working in my setup.
I'm having a bit of trouble setting up Multitouch for my current setup. I have gone through and tried setting it with synclient, but when I place both of my fingers on the touchpad, the pointer jumps/jitters around.
First issue is, now that I am running Debian "Squeeze", my laptop runs much hotter than before. Its definitely hot on the very bottom compared to when running Windows. Once the system begins to heat up, the fans start spinning faster, the system gets louder, etc.
Second issue is battery life. I am able to get 5 hours out of the laptop in Windows, but maybe 2.5 hours in Debian. I am assuming that these two problems go hand in hand. Now from experience with PC hardware, I know that the newer chips scale their frequency and voltage depending on demand. I don't think the computer is doing this correctly when running Linux.
By running cat /proc/acpi/processor/CPU0/throttling
I see that the CPU(s) are in T0 state (or 100%). Manually setting the frequency doesn't change anything either (via the gnome applet). Am I diagnosing this correctly?
I just installed Debian testing on my new ThinkPad T400s. Everything went like a charm, but, I have three questions to fix some minors: (A) When I reboot or shutdown, just before everything turns off message appear: [37.439999] thinkpad_acpi: THERMAL ALLERT: unknown thermal allert received
I have a Dell Precision M4500, Intel Core i5 CPU, running Linux (Ubuntu Lucid), and would like to keep an eye on CPU temperature. I've tried lm-sensors: sensors-detect didn't find any sensors; following its hint ("This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.") I tried acpi -V but got nothing thermal. The Gnome panel applet "Hardware Sensors Monitor" reports on GPU temperature but nothing else.
have a Dell Studio 540 and am currently running Fedora 14 x64 KDE version. All seems to work well except I have no sound. Support.dell.com tells me my sound card needs a RealTek driver as well as ALC888 HD driver.Now I don't use the HD integrated sound (back), so I am assuming it's the Analog sound hardware (that I plug my headphones in on the front of the machine).Not sure if that is clear or not, or maybe will have no relation whatsoever how ever I have no sound. I have installed other distros and sound works, but I would really like to use Fedora.
I have not used Linux in some time (I used to use it back when suse 8 was still out and mandrake linux was still around).
Recently I decided to give it another go and downloaded both the LiveCD and the DVD (both 64-bit versions AND 32-bit versions).
I have a Dell Studio 1747 Laptop (with the 17.3 screen). It has an Intel i7 1.6GB processor, 4GB ram and an ATI Radeon 4650.
My problem is that the LiveCD just will not work. It gets to its boot menu, but when I press enter on the boot KDE live CD option, it will either try to boot and then freeze, or it will boot, you will hear that startup music, but the display will go blank. Could it be that it cannot handle my display or the graphics card on the laptop?
Unfortunately I have Windows 7, which doesn't seem to be supported by the windows installer on the DVD, so I can't test if it would work that way.
I must admit that ubuntu has given me the same grief, and so I wonder if maybe the laptop isn't yet supported properly by linux yet?
how I could use a live system or something, to at least try linux for a few things (I would need to retain windows for games and stuff). I'm not into resizing partitions and things, so I would prefer something else that could work.
I recently bought Dell Studio 1747 with i7 processor. My fan keeps running fast and does not slow even when the load on processor is low or idle. In pre-installed Windows 7, fan works perfectly increasing and decreasing speed based on work load. The noise made by the fan is irritating.
From the Fedora 10 to the beginning of the Fedora 11, I was successfully enabling bluetooth device on my Dell laptop by putting hid2hci command as a system startup module:
Code: # echo "/usr/sbin/hid2hci" > /etc/sysconfig/modules/bluetooth.modules But the latest hid2hci command in bluez package now displays help information instead of turning on the (default?) bluetooth device:
[Code]...
Now your bluetooth device should be enabled during startup. Only one problem still exists, the state of the bluetooth device will be reset if you will turn it off using the hardware turnoff button. If you will turn it on again, you will be required to enter hid2hci command manually.
I am using OpenSuse 11.2 on a Dell Studio laptop. I have sound through the internal speakers, but no sound through the headphones.I am using KDE and Kmix does have a volume control for the headphone, and it is not muted. None of the sounds are muted.I have run the alsa update as described in another thread and that did not help.
I just bought a new Dell Studio 1558 and I can't turn the wifi on when logging to my account, the wireless card is installed correctly but the button (F2) doesn't work to turn the wifi on.
[You can see the keyboard shape here]
On windows there is a program from dell that associate these keys (wifi -F2- and Eject optical drive) to their functions.
I upgraded my Dell studio 1555 to Ubuntu 10.04, and now I don't seem to be able to stay connected to the wireless for more than a few minutes. Network manager never notices the disconnect, and it will usually reconnect on it's own in 10-15 minutes, but it just cycles like this endlessly. The wireless worked perfectly in 9.10 and I'm not really sure what is going on. Has anyone else seen this behavior, or maybe has an idea of something I can try? In addition I am having a problem with my laptop freezing. This happened in 9.10, but was very infrequent, now it seems to happen multiple times a night, and seems to be associated with my wireless making a connection. I'm currently posting from my Win7 partition because ubuntu us mostly useless right now.
ISSUE SOLVED: FOUND SOLUTION ON LINUX MINT COMMUNITY[URL]... The solution is for debian, but it worked for me on Kubuntu 11.04. I just installed Kubuntu, and my wireless is not getting detected. I tried a variety of solutions I found online, but none worked. It worked perfectly for Ubuntu Gnome.
When I tried installing the Broadcom drivers in the "Additional Drivers", I got an error that the driver could not be installed.
Has anyone tried that? I have a Dell Studio 1555 running 64-bit Ubuntu 9.10 for about 2 years with almost no issues but I plan to upgrade it straight to 11.04 64-bit (using fresh install because I also want to format the HDD and partition it in a different way).
What I'm reading in the web is though a bit discouraging as there seem to be a lot of issues with 11.04 running on this particular Dell model. Quite a shame as Dell is supposed to provide good experience on Linux since they had been selling laptops with Ubuntu preinstalled (or they used to...).
I have installed Fedora 13 and Vista 64 in Dell Studio desktop. In the Vista, the machine is quiet, but in Fedora, it is quite noisy. I checked running processes, I am not seeing anything to do with PC fan.
Here, "enable_msi=1" was not initially included in sound.conf, I added. After adding I find that volume change buttons are working, but sound is not coming. Mixer channels are all set to active mode and vol is MAX to 100. Mixer channels show two tabs -- one showing HDA_Intel and the other showing HDA_ATI_HDMI. Mic Jack mode is Line_in.
My Dell Studio 1735 laptop fails to install openSUSE 11.4 install from DVD. The installation tells me it failed to install "kernel.desktop" then grub only has a Floppy entry. When I boot to Recover System /boot has no initrd or kernels.
Strange thing is that the headphone jacks still work just fine. Used to be that unplugging the headphones would cause the sound to come out of the laptop speakers, but now sound never does. I'm wondering if the software that controls the routing of sound between the speakers and the headphone jacks is messed up?
I have a Dell Studio 1535 and can't seem to get recording from the mic jack to work. I was wondering if anyone has got it to work or not on Ubuntu 8.10 64 bit. I fiddled with the settings in System->Preferences->Sound and in Volume Control: HDA Intel (Alsa mixer), as well as the settings in the semi-CLI program alsamixer, but it doesn't matter what I do. I have failed to get it to record from the mic jack. It will only record from my internal mics, and I don't want that at all.
I've been attempting to install 32-bit Ubuntu 9.10 on my Dell Studio 1749 with the intention of making a dual-boot system. Attempting to install with a live CD using the default settings, I got as far as pressing ENTER on "Install Ubuntu" before the screen went completely black. The CD drive spun wildly, but nothing ever appeared on the screen. I tried the fix detailed here:
typing "nomodeset" as an option, and using the "apic=off" option. When I did this, I was no longer greeted with a blank black screen, but instead with a blinking cursor, but the installation still hung. The keyboard was unresponsive and I could not open a terminal. I also tried using the alternate installer instead, and got the same results.
After this, I tried installing using wubi, and on boot I get exactly the same results: black screen without "nomodeset" and a blinking cursor otherwise.
I should also mention that the same thing happens for every option on the installation screen, including the option to "try ubuntu" by booting from the CD.
Does anyone know what could be causing this issue, and how I might install ubuntu on my machine?
I'm currently trying to install ubuntu but the installation process hangs on the second page of the installation (right after select language) I am booting from a usb. NO other OS is installed and I'm currently in "try it now" mode.
i am using dell studio 1450..my distro is fedora 13.1 community remix..i have some problem 1- sound is not working,,, 2-wifi not working 3-lan card not working
