Right click on the taskbar empty space and select "Start Task Manager", you can leave it running and minimize it, it will give you an animated graph in the taskbar you can watch.
Depending on what your are doing on the PC, this may or may not be a problem.
If you are not doing much on the PC when it uses 90% then there could be a problem.

Why does my cq-62 laptop gives me warnings about High CPU usage?
I have a CQ61-420US Notebook with Nortons 360 installed. Recently I have been getting a warning pop-up from Nortons saying, I have High CPU usage. When I check the box I am taken to a Norton System performance page that indicates 90% CPU usage. Can anyone help?

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
ChrisHello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris -
High cpu usage for garbage collection (uptime vs total gc time)
Hi Team,
We have a very high cpu usage issue in the production.
When we restart the server, the cpu idle time would be around 95% and it comes down as days goes by. Today idle cpu is 30% and it is just 6th day after the server restart.
Environemnt details:
Jrockit version:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
BEA WebLogic JRockit(TM) 1.4.2_05 JVM R24.4.0-1 (build ari-38120-20041118-1131-linux-ia32, Native Threads, GC strategy: parallel)
Gc Algorithm: JRockit Garbage Collection System currently running strategy: Single generational, parallel mark, parallel sweep
Number Of Processors: 4
Max Heap Size: 1073741824
Total Garbage Collection Time: 21:43:56.5
Uptime: 114:33:4.1
Total Garbage Collection Count: 420872
Total Number Of Threads: 198
Number Of Daemon Threads: 191
Can you guys please tell me what would be problem in the server which causing the high cpu usage?
One more thing I would like to know is that why the total number of threads is 198 when we specified the Executor pool size as 25? I agree that weblogic would create some threads for its maintenance but around 160 threads!!! something is wrong I guess.
Santhosh.
[email protected]Hi,
I'm having a similar problem, but haven't been able to resolve it yet. Troubleshooting is made even harder by the fact that this is only happening on our production server, and I've been unable to reproduce it in the lab.
I'll post whatever findings I have and hopefully we'll be able to find a solution with the help of BEA engineers.
In my case, I have a stand-alone Tomcat server that runs fine for about 1-2 days, and then the JVM suddenly starts using more CPU, and as a result, the server load shoots up (normal CPU utilization is ~5% but eventually goes up to ~95%; load goes from 0.1 to 4+).
What I have found so far is that this corresponds to increased GC activity.
Let me list my environment specs before I proceed, though:
CPU: Dual Xeon 3.06GHz
RAM: 2GB
OS: RHEL4.4 (2.6.9-42.0.2.ELsmp)
JVM build 1.5.0_03-b07 (BEA JRockit(R) (build dra-45238-20050523-2008-linux-ia32, R25.2.0-28))

JAVA_OPTS="-Xms768m -Xmx768m -XXtlasize16k -XXlargeobjectlimit16k -Xverbose:memory,cpuinfo -Xverboselog:/var/log/tomcat5/jvm.log -Xverbosetimestamp"
Here are excerpts from my verbose log (I'm getting some HT warning, not sure if that's a problem):

So, I'm running with the default GC strategy which lets the GC pick the most suitable approach (single space or generational). It seems to switch to generational almost immediately and runs well - most GC runs are in the nursery, and only once in a while it goes through the older space.
Now, if you look at [Sun Oct 22 02:50:27 2006], that's when everything changes. GC starts running every second (later on it's running 3 times a second) doing huge sweeps. It never goes through the nursery again, although the strategy is still generational.
It's all downhill from this point on, and it's a matter of hours (maybe a day) before we restart the server.
I guess my only question is: What would cause such GC behavior?
I would appreciate your ideas/comments!
Thanks,

High CPU usage warning, how to fix??
Hey all -- First off, my laptop is brand new, and it is a Satellite C875D - S7120, using Windows 8. So far so good, everything seems to be fine EXCEPT...I am an artist and I have a couple of 3D programs installed. But every time I try to use them I get a "High CPU usage" error, like the art program is taxing the computer too much. I'm not a gamer... it seems to me that simple 3D imagery wouldn't cause this. But how do I fix it? I'm not that computer savvy...I've heard about registry problems but wouldn't have a blind clue how to get in there and fix anything... PLEASE ADVISE! -- Thanks in advance, Krystal
Ahh, Jerry, you are a friend in (my) need...will pounce on this ASAP! Twiddling around with this new device of mine is a challenge but also a learning experience. Probably the most important thing right now is NOT getting it 3D-ready but instead, teaching myself how to manage the innards...
Moki, someone on deviantART who is very skilled w/ Blender has said that they don't like the latest version because it is quite different from earlier versions. I haven't done anything with it in yonks, so once I get into it again, that shouldn't bother me. But it's true, "improvements" always seem to just weigh a program (any program) down instead of making it easier to use. That was why I have preferred older versions of some things instead of what's new out there, as the older ones are slimmer and not such resource hogs...
Disabling RayTracing...hmm! I shall definitely do that...plus try all the many other tips! *bookmarks page* I could even try that on this old XP, since I have Blender installed here also.
So if Toshiba is strong enough to handle graphics projects way beyond my modest little ventures (I doubt I'll be making movies anytime soon!), I ought to be able to get this puppy set up for it without too much trouble....let us hope.... -
High CPU usage - Rapid Battery Drain - Running HOT
Looking for help.. PLEASE!
Z10 - Model STL100-3 Software release 10.2.1.2179
Symptoms;
Occasionally, and for no apparent reason, I notice my Z10 getting hot in my pocket. I run the device monitor App and see a very high CPU usage, which consequently drains the batter very quickly.
I've tried all the solutions from every support group thread and blog. And I mean ALL!
Pulling the battery
Replaced the battery
Removed the SIM
Deleted G Mail
Removed all 3rd party Apps (2)
Stopped email sync
Stopped calendar sync
Turned off all radio
Turned Off Wi-Fi
Let it sit for hours, even days to let it finish doing whatever its trying to do
Etc Etc Etc.
Finally, I called BB support, they wanted $50 to talk to someone. I told them the issue, they said the device is bad and must be replaced. I said its software related!! They said.. no, its a hardware issue. Device is under warranty and they want me to just go get a new one. I don't want a new one, I want a fix! Stop the waste of BB $
Temporary solution
Eventually, I decided I would do a restore, back to the factory settings, and here's when I found something
I run BB Link, connect the device, do a back-up... and LOW AND BEHOLD.. this fixes the high CPU usage and the device runs great, very cool, low cpu and extremely long battery life.
Sadly! .. this problem reoccurs, after a few days, sometimes after a couple of weeks and just out of the blue.
I can force this fault to occur, simply by doing a restart of the device. Sure enough, it will run hot, use all the cpu and I will have to do a back-up to get it to settle down again. I've tried to wait for the so called 'indexing' to finish, but it never stops running with high cpu and doesn't help.
Can any one tell me whats happening and how to make this a permanent fix?
There are hundreds if not thousands of people having very similar issues, and many different methods to fix it. Its my belief that there is an underlying bigger problem that relates to all these differing fixes, but as yet.. I cant find it and none of these fixes work for me. For now... I will keep doing the occasional back-up and hope I get a response that can help.

The heat may be normal. After a little water damage incident, which I repaired, I disassembled my Z10 the find a small heat sink will thermal compound. This helps dissipate heat efficiently. I found a large number of air bubbles and possibly a large air pocket by the way the paste stuck to both sides. I removed the old paste and replaced it with artic silver paste and the z10 has been much much cooler. It use to run about 105*f and now it is around 85*f.
See this thread I posted for before and after pictures using a thermal imager.

@Curve8530 .....as much a s your discovery is appreciated, I hardly believe that most people will actually dismantle their phone to remove the paste and replace with arctic silver. Besides, what you are doing is not a fix for the actual problem....
In most cases, this heat is associated with apps using the CPU resources beyond the normal limits.
As an easy fix, finding and removing the app(s) in question followed by a reboot, solves the issue. In some cases an OS reload is necessary.... but under no circumstances I would even remotely suggest to any member to dismantle their phone and do what you did... -
Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
On close, I ordered ff to clear all history and cookies.
Notes that could be important (The behavior encountered while using it. This varies from time to time):
opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
==> The above seems odd
- Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
==> The above seems pretty odd
- When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
==> The above looks like that there is definitely something wrong here
This last one has some other things to keep in mind
- When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
- When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
If you need further details, feel free to ask.
Thanks in advanceTried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.
- opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript

==> The above looks like that there is definitely something wrong here
As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
Again, thanks in advance -

This will last several minutes then suddenly the high usage stops a few minute later the high cpu usage starts again.
I don't have any scheduled processes allowed to run.
Restarting the coldfusion service during a high CPS incident - the cpu usage just picks up where it left off when restarted.
I have assigned 4 CPUs (normal) or 8CPUs (as a test) to the VM and I get the same high CPU then low usage. This is a fresh install several months ago on a new VM.
I'd like some Adobe support on this issue but can't seem to find the contact phone number.
This series of high and low cpu usage first started Monday AM about midnight until 7:00 AM Tuesday was quiet and Wednesday this AM I'm having the same issues.
Ideas?
Update: While waiting for this to post - the high CPU usage started again and this time I stopped and restarted the Jetty service ... and the CPU usage went away...
Update: the high cpu started again and a restart of the jetty service didn't help --- neither did the .net service restart... the cf10 application service did stop the high usage...

will work on the tomcatlog issues next. -
This is a spin off from another thread which started off as slow inserts. But what actaully happens is every insert is preceded by select it turned out that the select was slow.
We have a multi-tier web application conencting to the DB using connection pool and inserting about a 100000 records in a table. To isolate the issue I wrote a PL/SQL which does the same thing.
This problem happens every time the schema is recreated or the table dropped and created again and we start inserting. When the table is empty, the selects choose a full table scan but as the records are inserted it continues to use the same even though after a few thousands of rows I run stats. But as its running if gather stats and flush the shared pool, it picks up the new plan using the indexes and immediately gets faster.
But in either case, full tablescan being slow after a few thousands of rows or using the index and getting much faster. Or me just doing the same select and no inserts on a table with 100000 rows, the CPU seems to be pegged to the core.
The code snipped repeated again
DECLARE
uname NVARCHAR2 (60);
primid NVARCHAR2 (60);
num NUMBER;
BEGIN
FOR i IN 1 .. 100000
LOOP
uname := DBMS_RANDOM.STRING ('x', 20);
primid := DBMS_RANDOM.STRING ('x', 30);
DBMS_OUTPUT.put_line (uname || ' ==> ' || primid);
SELECT COUNT (*)
INTO num
FROM TEST
WHERE ID = 0
AND (primid = primid OR UPPER (username) = uname OR uiname = uname
AND (deldate IS NULL)
ORDER BY TIME DESC;
INSERT INTO TEST
VALUES (0, uname, uname, 1, uname, primid);
IF MOD (i, 200) = 0
THEN
COMMIT;
DBMS_OUTPUT.put_line ('Commited');
END IF;
END LOOP;
END;This is the original thread
Re: Slow insertsMaybe if you post the actual code, or a code as similar to the actual code, the users of this forum may provide you with more appropriate suggestions.
Personally, I would like to understand what is the logic behind, so I can provide you with better advices.
Anyway, let's focus on the code that we currently have on the table.
Why your CPU goes high?
- Huge amount of LIOs produced by SELECT statement which is executed 100000 times.
- Usage of single-row / aggregate functions
- You mentioned you have some indexes created on table TEST. Index maintenance consumes some CPU as well.
Let's focus on the SELECT statement, since it is the most important reason for having high number of LIOs thus having high CPU usage.
I built a test case using the query you provided, with one difference, I named TEST table columns as COL1, COL2, etc. And instead of 100,000 cycles, I did 10,000
declare
uname varchar2(60);
pname varchar2(60);
num number(5);
begin
for i in 1..10000 loop
uname:=dbms_random.string('x',30);
pname:=dbms_random.string('x',20);
select count(1)
into num
from test
where col1=0
and (col2=uname or upper(col5)=pname or col3=uname)
and col4 is not null;
insert into test
values (0,uname,pname,1,uname,uname);
if mod(i,200)=0 then
commit;
end if;
end loop;
end;When I run 10046 trace and made tkprof report, I got the following for the SELECT part:
SELECT COUNT(1)
FROM
TEST WHERE COL1=0 AND (COL2=:B1 OR UPPER(COL5)=:B2 OR COL3=:B1 ) AND COL4 IS
NOT NULL
call count cpu elapsed disk query current rows
Parse 2 0.00 0.00 0 0 0 0
Execute 10050 0.48 0.43 0 0 50 0
Fetch 10000 94.07 94.37 0 2910664 2 10000
total 20052 94.56 94.80 0 2910664 52 10000As you can see, tkprof report indicated high CPU usage and 2,910,664 LIO calls.
The execution plan (I didn't include that part) indicated FULL TABLE scan on table TEST was used.
At this point the goal should be to reduce the number of LIO calls.
For this purpose I created the following indexes:
TEST_IDX1 on TEST(col2)
TEST_IDX2 on TEST(col3)
TEST_IDX3 on TEST(upper(col5)) - a Function Based Index
Let's forget about the statistics at this moment.
I will use index_combine hint in the SELECT statement to make CBO to try every index combination for listed indexes (B-Tree) and make bitmap conversion.
The new code looks like this
declare
uname varchar2(60);
pname varchar2(60);
num number(5);
begin
for i in 1..10000 loop
uname:=dbms_random.string('x',30);
pname:=dbms_random.string('x',20);
select /*+ index_combine(test test_idx1 test_idx2 test_idx3) */ count(1)
into num
from test
where col1=0
and (col2=uname or upper(col5)=pname or col3=uname)
and col4 is not null;
insert into test
values (0,uname,pname,1,uname,uname);
if mod(i,200)=0 then
commit;
end if;
end loop;
end;After running 10046 trace and creating tkprof report, I got the following result:
SELECT /*+ index_combine(test test_idx1 test_idx2 test_idx3) */ COUNT(1)
FROM
TEST WHERE COL1=0 AND (COL2=:B1 OR UPPER(COL5)=:B2 OR COL3=:B1 ) AND COL4 IS
NOT NULL

0 INDEX RANGE SCAN TEST_IDX3 (cr=19943 pr=1 pw=0 time=107200 us)(object id 52990)As you can see the number of LIO calls fallen dramatically. Also CPU time is significantly less.
The second code completed in few seconds compared to the previous one which needed about 100 seconds to complete.
Please be aware that this is just an example of tuning the code that you provided.
This solution might not be suitable for your actual code, since we don't have any information about it. That's why it is important to give us as much information as you could, so you can get the most appropriate answer.
If the test code is similar to the actual one, you should focus on reducing LIOs calls.
In order to achieve it, you may want to use hints to force an index to be used.

Unusually high cpu usage with iMovie 6.0.3
I'm having trouble with very high cpu-usage. Just the open imovie app is taking up about 50%, during playback it sometimes peaks over 100%! The project file is pretty big (about 30 gig), but that is mainly because of the amount of footage imported into it. The movie itself is about 25 minutes in length. There is some audio editing going on: some soundeffects, musicfiles (no drm-protection), audio commentary that i recorded within imovie. I know that imovie has trouble when there is a lot of audio/audio editing involved and this project is probably a little more complex than other stuff i did in imovie, but i never had such problems. i can hardly use playback anymore. I recently updated Quicktime to 7.6.4 and Perian to version 1.2.1. Any ideas what's going on or how to work around the problems? Since the movie is about 80% finished i don't really want to start all over again. Thanks in advance for your input!
Hi Klaus1
I have several plug-ins by cfx and the slick volumes 4, 6 8 and 10. I can post a list of all of them if you like. Up to now they never made any trouble, but you'll never know...
The edit in the timeline is about 25 minutes long. But the project file contains captured dv-footage of about 2 hours, so that alone adds up to something like 26 GB. Then there are a few rendered effect-clips done with some of the plug-ins like stabilizing or color correction which also add to the 30 GB, as well as some audio-files (some music, my voice-over commentary). I emptied the trash several times while working on the movie. At this moment there are only a few MB of erased audio in it.
It all sounds a bit like this is an insanely huge and complex project, but as i said, i have done projects like this in imovie without the massive cpu-usage. I'd like to continue to use imovie, but if this problem keeps coming up with future projects, i might as well take the step and switch to Final Cut Express.
For now I will try your idea of exporting the movie as it is now and open it in a new project file.
Thanks for your help and input so far! -
DNS server process, high CPU usage
Hello,
I am having a problem with high CPU usage on DNS process. We have 1921 setup in network of about 100 workstations that use it as DNS server. It also performs split view functionality for couple of domains in order to avoid hairpin NAT. I know that a router is not fit for heavy server duty but such setup was unfortunately necessary.
In peak work hours we oftenly have CPU hitting 100% with DNS server process being the root cause,and on several occasions we had DNS process stuck in such state for prolonged periods of time during which other router functions were affected (t's a default gateway, IPsec concentrator etc.). Sometimes shutting the process and restarting it would solve the problem, but once it required a full reload in order to restore functionality (such was the description that engineer on duty reported to me).
Forwarder queue statistics:
Current size = 0
Maximum size = 86
Drops = 0
IOS upgrade did not help, we are currently running 15.2(2)T.
The question is ... is such behaviour (CPU load) to be expected on LAN with 100 workstations due to slow CPU on router or we have bugged IOS DNS server (requiring a TAC case)?
The previous solution seem to do this functionality quite nicely (even though it was also a router), so I am not inclined to think that we are dealing with someone DoS-ing the DNS (WAN access to DNS is of course forbidden)
P.S.
Since we moved servers off the routers DNS, we do not receive complaints, but we had a couple of unresolved messages a day while mail server was using router for DNS. I am suspecting that an old bug where IOS DNS servers occasionaly sends clients back empty DNS replies (properly formatted message but without A record) could be still around?hi,
i have the same problem on UC540 and 2911 on IOS 15.0.1. CPU high, router crashed. Reboot helps but until CPU usage spikes again. the only fix is to remove "ip dns server" from config and use a different DNS server

Continual HD activity, high CPU usage when idle
I got my first notebook, a Compaq V2000, a few weeks ago and have Arch set up pretty well on it but I have a few issues. Even when the machine is sitting idle it sounds like the HD is doing a read (or whatever) about every 5 seconds. This only starts after I log into Gnome and stops if I log out.
I tried a couple of things with hdparm:
If I try 'hdparm -y /dev/hda' the drive goes to standby but immediately spins up again.
'hdparm -B 255 /dev/hda' disables APM and stops the cyclic behavior. This would seem to be good but during the 5 second cycle the drive alternates between quiet and noisy and this leaves it in the noisy state.
I tried to determine what might be causing all this disk activity so I edited lilo.conf to remove "acpi=on apm=off" from the "append=" line and in rc.conf I put a ! in front of all modules and daemons and rebooted. I removed the applets from task bar. No change.
I ran top to see if I could tell what was accessing the HD but I'm not knowledgable enough to make much sense of it. I did notice that on my notebook the top summary shows:
CPU: ~30% user, ~10% system, ~60% idle with 'wait' bouncing between 0 and 5%
On my main computer, also running Arch/Gnome, I get
CPU: ~2% user, ~1% system, ~97% idle with 'wait' solid at 0%
On the notebook, if I run hdparm -B 255 /dev/hda the CPU #'s for user and system remain high but the wait # drops to zero and stays there.
I don't think all this HD activity could be good for my machine, and I know I find it very annoying. If anyone could help me stop all the HD accesses and understand the high CPU usage I would appreciate it.I loaded lsof and frankly it scared me. It listed what looked like a couple hundred files and I didn't know exactly how to use that information.
Then I tried laptop-mode-tools. The man pages didn't sound too promising since it uses, among other things, hdparm, which I already tried with mixed results. I gave it a try anyway and right out of the box, with no configuration, it worked. HD access when idle dropped to essentially none, the drive spins down and the cooling fan runs much less frequently.
So far all I have changed in the config file are the HD idle timeouts. The default of 5 seconds was starting and stopping the HD too often so I changed that to 20 seconds for now.
Whatever laptop-mode did to stop the 5-second HD accesses the effect persists even if I run 'laptop_mode stop' and '/etc/rc.d/laptop-mode stop'. When I get the time I should be able to use 'laptop_mode status' and laptop-mode.conf settings to determine exactly what the magic bullet was.
Thanks, lucke. I never would have tried laptop-mode on my own because I thought it only duplicated functionality that I already had with hdparm and powernowd. -
Excessively High CPU usage on my Equium M70
HI,
Recently in the last month my CPU usage as been hitting 100% when Im not running any taxing software (just internet explorer and windows media player).
This is slowing down loading times and the area near the fan is pretty hot.
I have an Equium M70-337, with a 1.7 centrino processor, and now 2 gigs of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problem like this, now it's just started happening recently, I haven't installed anything that would do it, there are no unnecessary programs running and this was after I restored my comp to factory settings with the startup disc (about a month after) so it seems to have come from nowhere. On the task manager list it shows my web browser and media player using up the majority of CPU but I could have sworn that they didn't use up this much before.
I don't know if the RAM would have been a factor but it was the correct ram for it and windows acknowledged to 2 gigs.
Why would this have happened suddenly, any ideas guys?Hi
I have the same notebook model and at the moment I do not have such problems. To be honest I have made clean OS installation 3 months ago and after Microsoft update installation I have noticed that notebook does not run like before. Just for example: if I use IE7 intensively with several different tabs in task manager I can see that IE need over 300.000 k of memory and somehow blocks. After closing IE and ending the IE process sin task manager I can work normally again.
I really do not know how is your OS configured but in task manager you should see which running process is responsible for high CPU usage. Maybe some antivir application? Sorry but on this way it is really not easy to sayt why this happen. Play little bit with running processes. -
Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

SBS 2011 - High CPU usage - Help me Microsoft forums! You're my only hope!
My company supports a client that has a SBS 2011 server. For about the past year, we've been fighting a recurring issue with performance on this server. There are about ten local users and four remote users. The server's CPU idles at
about 60%-80% but is usally running when under *any* load from 80%-100%. If you do anything on the console, it will stay pretty much at 100%. These are not power users by any means. The server is utilized for file/printer sharing, Exchange
2010, and one flat file database application (non-SQL). SharePoint is not utilized.
Needless to say, our client is frustrated. When opening files, using their database application, or doing anything Exchange-related, there is a large amount of lag on the client side. First, here are the server's specs:
Make:Dell PowerEdge T420
OS: SBS 2011 Standard SP1
CPU: 2 - Intel Xeon E5-2407
Memory: 32GB
RAID: RAID 1 - Operating System (C:)/Data Volume (E:) | RAID 5 - Data Volume (D:)
Here is what we have tried to resolve this to finality:
* Doubled resources - Initially the server had a single physical processor and 16GB of memory. While these specs alone should have been fine, and were fine when the server was installed, we had periods of time where the server would just sit all day at
100% usage. We doubled the resources and while this seemed like it would fix the issue, we are still seeing abnormally high processor usage.
* Removed all monitoring tools, antivirus, and backup software - As part of our testing, we removed our monitoring agent (LabTech) and antivirus (GFI Vipre). Mozy is utilized for an off-site backup so that was disabled. No dice.
* Verified updates - We made absolutely sure the server was 100% patched.
* Malware/Virus/Rootkit checks - We have ran scans checking for any potential issues with security.
* Ran MBSA and MBCA to fix any issues with the server's configuration.
There is no single process which is using all of the CPU, or we would simply be able to narrow it down. Our calls to Microsoft support have yielded no answers. The last call ended with Microsoft stating that a SBS server should always be running
at high CPU usage. Meanwhile, we have many other clients with less-beefy servers, with more users, who have no issues like these.
So, I'm turning to you all. I will gladly provide logs, configuration settings, even remote assistance sessions if you all can help shed some light on what might be causing my issues.
Thank you!Some comments/ideas:
How long was the server running after this screenshot? I ask because store.exe is only got a 1GB of RAM which is really low - it should grab most of the RAM within a few hours.
The server was up for about 12 hours. I believe an adjustment was made before to limit the Exchange memory usage.
Strange that SearchIndexer (wsearch service) is so high although that may be a startup condition.
The LT* processes seem to be a 3rd party monitoring tool - no idea why it would ever need that much CPU though (I thought you disabled this?).
We had, but we cannot go forever without monitoring our client's server. It has been pulled off in the past and results on performance are pretty much the same.
The taskmgr process run by amnet_admin has used a lot of total CPU Time. What is it? (can't see the command line).
That's the user I was logged in as when I took the screenshot. Even the task manager seems to eat up the CPU.
The sqlserver process right above it is also busy - may want to look at the command line and figure out which SQL database that is (SBS has 3 - WSUS, Sharepoint, and SBS monitoring)
I believe that's the SharePoint database. They don't currently use their site. Would you recommend a removal and reinstallation? I would not completely remove as I know SBS doesn't like you removing parts of the complete package.
Strange that vds.exe is 10% - that is the interface to the disk management interface IIRC. Perhaps your monitoring service has gone awry here - definitely lose it.
I'll see about pulling it off and I'll see if there are any improvements.
