[SOLVED]Need a laptop hardware guru

Post by omegaman »

Completely frustrated at this point. Back story: bought a used Dell D800 laptop. 1.8 Ghz proc, (upgraded to 2 GB RAM). It came with XP installed but was incredibly sluggish. I wiped XP and as a Linux newbie decided to install Mint10 Main ediition. Still not working riight, and the HDD died. I replaced that. Reinstalled everything but then notice an issue with Youtube. That led me to find the CPU was not scaling properly. It was running at 1.4 Ghz on battery but only 600 Mhz on AC power. Lots of trouble shooting, only to attach a different AC adapter and now it powers up at 1.8Ghz and scales properly.

So you may now ask, why are you frustrated? Fair enough. Now when powered up on AC power I got about 10-12 minutes, usually websurfing at this point, and the temp applet says its 34-45C and then the CPU Fan kicks on high, CPU scales down to 600MHZ and CPU usage is at 97-100%. Laptop is slow to react, if at all. I get System Manager open and it shows nearly every process is sleeping, but Sys Manager is using 68% of the CPU, but the applet shows CPU at 98%.

I get it shut down, power back up and things are okay for another ten minutes or so. If I hard restart, wireless never connects. Now on battery, as I type this, temp is 50.5C CPU usage is 19-34% and the cpu is scaling.

When the CPU Fan kicks on high, nothing is happening, but CPU usage is at near 100% speed is 600Mhz and I am jsut sitting here with my arms crossed watching nothing happen. Firefox is open but I'm not doing anything yet CPU usuage is near 100%, Fan is racing and the temp is well within normal limits (fromwhat I can determine).

Anyone have any ideas besides tossing this thing out the window? :roll:

Your last idea seems like a good one, but don't forget to open the window first :)

Before you do that have a look to see what is using all that power. I know you have looked in System Manager, but let us see if the terminal can give a bit more useful information.

So boot your laptop and as soon as you have done so open a terminal window and type:

Code: Select all

top
Leave this window open (and visible) whilst continuing to use your computer and it will tell you what is using all the power (without using too much itself). When you see a high load listed in there make a note of what it is and if it doesn't sound too important you can always kill it by focussing the terminal window and typing k followed by the pid of the process using all the resources.

I am not sure if this will give you any more information than taskmanager, but it might so give it a go.

Okay, I had a few minutes. booted and started a terminal with top. copying and pasting can be a fun experiment since it is constantly updating. What I noticed is two users (me and root) and then if I scroll down alot of the same processes are in use, but the second time Xorg comes up it is usitng 47% of the CPU and the Third time it shows up it's using 51% of the CPU???? This is getting a bit above my pay grade, but why would there be three instances of Root running, and why two of the three using most of the CPU time especially when the pc is doing nothing but having Firefox open and typing here.

additionally, that is when the fan kicked on high, cpu scaled to 600 MHz and CPU usage at 98% and CPU temp 39.5C

Re: Need a laptop hardware guru

Firstly I would disable compiz. You used to be able to do that by opening the control centre and going to Appearance, but I notice that on my machine the option to disable effects is no longer there. This might be because I have completely removed compiz from my system I don't know.

You could open a terminal and run the command:

Code: Select all

killall compiz
But that may well remove all the window decorations from your windows. I guess you would have to then run the command

Code: Select all

metacity --replace
But I am well out of my comfort zone here because I don't deal with compiz in any way, so you may be better waiting until a compiz user comes along who can tell you how it should be done these days. Run the first command anyway and see what happens. Ignore the lack of window decorations, they will come back when you reboot, what we want to see is if compiz is causing the freezing problem or not.

A couple of the statements you make puzzle me a lot.
if I scroll down alot of the same processes are in use
It is impossible to scroll down the output of top it only displays a set number of lines all the time that is how it works. Secondly where are these processes that are the same? I can't see any.
why would there be three instances of Root running
Where do you get the information that this is the case? I think you may be misreading the top output. The word root appears multiple times because the user 'root' is running multiple processes in the same way that the user bill is. This is nomal.

A tip here, if you want to freeze the output of 'top' so that you can post it here just hit Ctl/c with the terminal focussed, this will end the command and you will be able to read the output at the time you ended it.

Thanks.

I'll give that a try later.

As for the three instances, I maximized the terminal window, and there wre three sets of information with the PID USER PR header line, so I took that as three sets of information, each time Xorg was the first and each had a different CPU usage % . Firefox bin etc... I took that as three instances, but maybe I'm reading it wrong, or maybe it was because I didn't (know how) pause it to copy.

What is really odd is how the CPU runs at 98%, things slow down, but even looking at TOP, it doesn't seem the CPU usage adds up, to that, and the fan is on high but the temp is reported in the 35C range.

Re: Need a laptop hardware guru

Post by omegaman »

While driving to the office, thinking I'm not sure if this is a hardware or OS issue. Might try a Live version of a different version, install the wireless driver and see what happens. I could also install XP to see if I get the same issues, but just the updates would take hours and I have better things to do with my time (edit video, print labels for my wife's business, spend time with the kids...LOL)

Not much free time this week, a couple video shoots, and need to rehearse for a gig this weekend. I'll report back when I learn something,. In the meantime if anyone has any ideas, please chime in. I can sit there surf the web for 15-20 minutes before the cpu fan kicks on, though the temp is in the 30C range, scales it down to 600 mhz and it slows everything to a crawl, or I can surf for 5 minutes, try to play a youtube video and that kicks on the CPU fan and scales it down to 600Mhz. So I solved the AC adapter issue with the CPU performance, but now, I don't know if its hardware or something in Mint screwing with the CPU.

Re: Need a laptop hardware guru

You are quite right, a fan going full speed and a cpu usage of 98% with a reported temperature of 35deg does not make sense in the least (unless the cpu is faulty). I am rapidly running out of ideas here, and it seems you do really need a 'laptop hardware guru' because I don't understand it at all. If you can get your laptop to run for long enough to achieve this, you could try running the command:

Code: Select all

sudo apt-get install --reinstall lm-sensors
Which is the program responsible for reporting hardware temperatures, but even if you achieved that I would not know what the next step would be. You can try simple things like cleaning any dust out of the fan vents, but I am sure that is not going to achieve anything remarkable.

I hope somebody else can help you because I don't think I can, sorry.

First the obvious: Turn computer upside down and check the slots over the fans. Any dust there could clog the fans and make things hotter. Second, what kernel are you using? Open Terminal and run:

Code: Select all

uname -r

Copy/Paste the results here. Some of the newer kernels have less CPU usage and better heat handling.

If that does not do it I recommend going to 2.6.37 Kernel If you are proficient then downloading the source code and compiling it for your system is best. Or, check on Google for a .deb installer and follow the instructions closely.

LOL this is all new to me. Had the system up for an hour, looking around (trying to find out why when I minimize a window it doesn't show up in the bottom panel like I think it used to) checking email, some forums, facebook online etc. then went to my site and went to run a video, 15 seconds in, fan comes one, temp is fine, CPU scales to 600 Mhz and usage is up to 97% and he video won't play. frustrating to say the least when I can't even watch myself LOL
just rebooted temp reported at 56C.

I'm coming to the party late . . but just noticed your top output, and that xorg was uppermost . . what is your graphics situation ?
another reason to suspect graphics . .

It's an Nividia NV34M GeForce FX 5400 64MB... I was using the nVidia drivers, I disabled them after your post and played the video, thought that did it until it got three quarters thru the video and the fan kicked on high. CPU temp 33.5C and the usuage was in teh upper 80's-upper 90's during playback before it scaled back to 900 Mhz.

It does seem to indicate that it happens when the cpu or gpu is stressed. Last night I was up and running for an hour and all was fine until I played or tried to play a video. This morning up for 10 minutes tried to play a video and got through more of the video. Oh, and last night when I re-booted at one point I set the CPU to 600Mhz and it played thru the video, though it was not smooth, a bit jerky. (watching another thread on Youtube and problems, I disabled hardware acceleration the other day but it didn't seem to make a difference) but it played thru and didn't kick the fan on high. BTW even though some of the vids on Youtube are HD, I am playing them at 360p.

I have winxp here, could re-install that to determine if its a hardware or software issue, but don't really want to do that.

booted Live CD of Isadora XFCE, default video drivers, same thing in firefox, didn't install chromium as system slowed down.
starting to think its a fault CPU, if so, what to do? I guess I could just avoid watching videos on this machine, but as a video guy that might be tough :?

Or you can open a terminal and type

Code: Select all

sudo apt-get dist-upgrade
This will upgrade the system to the latest stable kernel.

GeForce FX 5400
I cannot find that model number at Nvidia ? Are you sure ?

Please post the output of the following terminal command (you can copy from below by clicking SELECT ALL)

Code: Select all

lspci -v | perl -ne '/VGA/../^$/  and /VGA|Kern/ and print'

I'm going to give you the same suggestion I gave another member just now . .

And while you wait on me to respond back, please open the Update Manager, go to Edit -> Software Sources, and check the Backports repo, go to the Other tab, and click the Ubuntu/Medibuntu repos that say Restricted and/or Non-Free . . reload when you close that window. Now go to Edit -> Preferences and in the Levels tab, click the Visible only for 4 and 5. Go to the Update Method tab, check to make sure Satisfy changing dependencies.. is already checked, mark it if it isn't. . . close. Hit the reload button back at the main window . . once it has updated, are there any xorg-video-nouveau, or something like that, any nvidia, in the updates ?
