Fan kicks quite loudly every minute on Satellite L30

Hi,
I'm using a Satellite L30 laptop. One thing I am finding annoying is that the fan kicks in quite loudly every minute or so, then quietens down for a while. Using a temperature monitor it looks like the fan kicks in when the temperature rises above about 50, then slows down as it falls. When the temperature is below 45 the fan stops altogether which causes the temperature to quickly rise back above 50.
I want to change the power management settings so that the fan stays on quitely at lower temperatures. I have a desktop computer where it is possible to change the fan settings in the BIOS, but I can't find anything like this on the laptop. Can anyone suggest where I should look - are there any open source or shareware tools which will do this?

Maybe you should check this topic: http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=18258
The trick:
1. You need in Power Saver the performance profile, that uses performance fan control.
2. You need to make another profile (for example called Silence). In this profile you need the optimized battery fan control, the other options doesnt matter.
3. Then, you must activate the performance profile, and wait, until the fan speed raises (begins to cool down the CPU). Meanwhile the fan speed is high, you must speedily switch to the silence profile (with the Fn+F2 combination you can choose, which you want).
4. And voila, the fan rolling remains on medium (not noisy) speed so long as you turn off or hibernate the computer, and the temperature drops to 40-50 degrees.
This trick works only if you use Windows XP, because Power Saver doesn't work under Vista. (I have Satellite L30-134, BIOS number is 2.60.)

My iMac's fan runs quite loudly.

I only got the computer yesterday from Apple, but it was refurbished. It's an iMac 21" 2.7 1TB.

When you say that the 'fan runs quite loudly' do you mean that the fan is making an unusual noise such as a buzzing or clicking sound, or do you mean that the fans sound like they are running at full speed?
If the fan is making a buzzing or ticking noise then that could indicate that something is touching or rubbing against the fan. If you just purchased the iMac then I would contact Apple to arrange for a replacement.
If the fans sound like they are running too fast then it could simply need an SMC reset. To do this, power down the iMac and then disconnect the power cord for ~15 seconds. After 15 seconds plug in the power cord while making sure you don't press the power button. Here's an article that provides additional information on this condition and why it occurs.

I keep getting kicked off of my wifi on my macbook pro. It is the wifi in my house. I get kicked off like every few minutes or so. Why is this and how can I stop it?

I keep getting kicked off of my wifi on my macbook pro. It is the wifi in my house. I get kicked off like every few minutes or so. Why is this and how can I stop it?

I think the other devices are fine. I'm not sure. It usually only happens like a couple days out of the week. I do know that the network I'm using when I click on the wifi symbol at the top of my screen doesn't have a padlock on it. It IS MY network that is at my house, but maybe that has something to do with it.

Satellite A300D - Fan running very loud and notebook is getting very hot

I was wondering if anybody could point me in the right direction as what to do with the overheating problem i currently have with my A300D. I have had the laptop for under a year so it is still under warrenty but i am not sure where to go or what to do in order to repair it.
The problem: Around two months ago I noticed the fan running very loud and also the laptop becoming very hot. Now it runs so hot the laptop switches itself off completly. The heat being fanned out of the laptop is so hot! burns your my infact.
Has any one any advice they could offer me.
Thanks
James

Hi James
You wrote that you have the notebook under a year so my questions is did you already clean it?
The notebook should be cleaned every 3-4 months and I do this every 3 months. Every time I do it Im wondering how much dust comes out and after this procedure the notebook is a lot of cooler.
Here is an interesting Toshiba article about this:

Compressed air spray is really useful and you should check it yourself!!! ;)

Hp Pavilion 17" Laptop fan gets very loud.

I just bought the HP Pavilion 17-e137cl today at Sam's Club, and I love the computer but I have a complaint. I had to return an Asus that had a terrible trackpad, but it was a lot quiter. The fans on this one kick in within a minute of booting, and it's pretty loud even during web browsing. With Netflix, it can get a little distracting. It does it on Balanced and High Powered battery modes. Any ideas? I've updated the motherboard and processor drivers, but it still gets loud regularly. The temps are reading anywhere from 30-60 degrees so it's not really overheating.

Hello gorebs
Welcome to the HP Forums!
I understand that the fan is constantly spinning. I apologize for the inconvenience, but I will do my best to assist you! I will start by providing generic troubleshooting steps for when the fan spins constantly: Fan is Noisy and Spins Constantly
If these steps do not resolve the issue, you should accept the possibility of overheating. I believe you should try these steps to address overheating: Reducing Heat Inside the PC to Prevent Overheating
If you cannot resolve the issue, please contact HP to address the hardware. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide
Please let me know if you have any other questions or concerns. Thanks for choosing the HP Forums. Have a great day!

Full Garabage Collection every minute in oc4j_soa instance

It looks like a Full GC cycle is run exactly every minute on a IDLE BPEL instance that does not have any instances. This is a basic 10.1.3.1.0 BPEL install with no Out of the box parameters modified / tuned. Is this a known issue / bug with a fix ?
Also, we have 3 - 5 Asnyc BPEL Processes that involve human workflow. The invocation rate of these workflows is medium (100 instances per hour),but the instances may last long due to human workflow. What would be the recommended settings for these in terms of worker, invoker and dispatcher threads, DB Connections etc? Is there any tuning guide/ spreadsheet available for computation of optimum values ?

Thanks for the replies. Let me clarify a few things:
1) We've tried setting -Xms to -Xmx (a long time ago, so maybe it's time to revisit), but doing so caused our app to exhibit other strange behavior due to the fact that no full GCs were ever done until all the allocated memory was exhausted. These full GCs, when finally triggered, ended up taking quite some time due to the fact that there was a lot of compaction (or attempted compaction) going on.
2) I don't have a problem with doing full GCs (I use the term full GC because both a young and old generation GC happens at every full GC), but I have a problem with the full GCs happening every 2 or 3 seconds and taking up 100% cpu for minutes (because the concurrent phases would run back-to-back for every full GC). Especially when the app has 1/10th the volume of our other app which does a young gc every 20s or so and a full gc every 5 or 6 minutes.
We've gone ahead and set the initial heap size to -Xms5g for today's run. We initially went without setting -Xms (again, just like our other instance) and we started seeing full GCs almost immediately as the JVM did not want to allocate more heap. We then went with -Xms2g which delayed the full GCs for a few hours until the used heap got close to the allocated heap. Full GCs then kicked in for cycles (15 or 30 mins long) until the JVM increased the heap by a few hundred mb each time.
As I've stated, I'm struggling with the fact that we have another instance of the application that does not exhibit this behavior and does not have -Xms set at all. And the only thing I know that is different is that during startup, the amount of data we load is quite large (~6-8gb) and so our "min size" is already pretty large before starting to handle additional volume. Hopefully setting -Xms to 5g will replicate the starting point of the original instance.
I'll respond back with updates.
Thx,
Josh

I'm wondering if anyone else has had problems with their imac fans being extremely loud when running at slow speeds? When the computer heats up enough for the fans to run at higher speeds they quiet down. New HD fan was just installed.

I have an imac that I've had for a couple years. The fans have always been loud when running at the slower speeds. When the computer heats up enough for the fans to run at a higher speed the fans quiet down. I had installed SMC fan control after multiple attempts with Apple to get the fan issue resolved. That seemed to keep the fans quiet enough. I've never had a problem with overheating. Recently the fans were becoming loud again even running at the slightly higher speeds so I took it to my local Apple store and they replaced the hard drive fan. I got it back and it's now as loud or louder than ever!! And, now SMC fan control won't "stick." The fans will speed up, but then gradually go back to the lower "loud" levels. I'm at a loss as to what to do next.

Thanks jared,
I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.

Fan suddenly runs loudly for no reason

OK this is a weird one. I was running my iMac this evening, doing just general stuff (running Google Earth, actually), when suddenly the fan kicked in and started roaring loudly for about a minute, before subsiding back to its usual near-silence.
It actually sounded at first as my drive had started to spin, but I had no disk in the drive. I've had the computer since December and it has never made this sound before.
Any idea what might have caused this? It's concerned me enough that I'm performing an emergency backup of vital documents, just in case. This actually spooked me more than the loss of Windows XP access that resulted from updating to 10.4.9 last night (but that's another thread).
Cheers
Alex

Hi Alex
As it returned to "normal" I doubt if anything is wrong but it would be worth having a temperature moniture app to monitor things - either of these are good products.
iStat Pro which is a widget and gives temperature and fan speeds as well as other monitors

Fan randomly running loud + computer not responding

I have been facing a problem for the last several weeks on my PowerMac G5 that technicians have not been able to solve either.
The computer randomly stops responding and the fans start accelerating slowly until they reach their top speed and then stay at that speed for indefinite periods of time. I cannot see any pattern in this - it happens both when the computer is running some process and when it is idle.
Each time this happens, the only option for me is to do a hard powerdown (hold down the power button).
I saw another question about fans running at high speed, but that case, it seemed as if the computer continued to respond.
Any help on this would be appreciated.

I am having the same problem.
Now before you start taking advice to back up all your data, reformat your hard drive, and reinstall all the software; please take note of a few things:
first off, I'm disappointed/frustrated/melancholy that this is happening to me. I spend $5000+ for a "reliable" Apple computer. Then it doesn't want to turn on because its not safe. Sorry if I drown this post with bitter sarcasm but I am coming to the end of the line with my patience.
I called Apple Care, read a bunch of posts (here and elsewhere), and yes I do know about the SMU Reset button (like that really does anything?).
My problem happened a few weeks ago and I thought nothing of it at first. There was a power outage for a quick second and it turned everything off. When I went to turn on my computer, there was no chime, the red light was on, and the fans were running and eventually began running very loud. After letting it run like that in hopes of the screen lighting up, I turned it off by holding the power button. By the way, there's nothing on the screen and the keyboard doesn't work (I use a wireless keyboard, but I plugged in the OG cord keyboard to push whatever series of buttons recommended by these "geniuses") Trust me, the computer doesn't make it to that part of the boot process, so stop with commandoption+PR or F12 to get the CD out. It doesn't work! What's up with this computer! It can handle all these intense calculations,etc. but a power surge is going to shut it down indefinitely.
So I left the computer came back the next day, turned it on and its fine. Cool, I'm happy. It's Working!! I go on a few weeks, then I go to turn it on this Monday, same problem. But actually a worse situation. I had a client come over and the computer wouldn't work. I looked like a idiot. Couldn't do anything cause my computer didn't want to turn on. I do music production/editing. I use my G5 for running ProTools LE. I have other programs but that is the main one I use. There's nothing wrong with it. It's optimized for use with the mac. So those people who are going to advise me to uninstall all my software and all that - I appreciate your concern but don't give advice when you don't know anything!
So I am getting frustrated. My client left a little disappointed, but what can you do? I tried to call AppleCare on Mon. but it was Memorial Day. So I waited for Tues.
Tues morning, my computer turns on like everything is fine.
I'm happy but cautious. I talk to AppleCare rep. He tells me that it is a common problem they have heard about with the G5's. Wherever blackouts, brownouts, spikes, sags, dips, and other electricity inconsistencies occur, the Power Mac G5 has a breaker in it which flips so it doesn't receive uneven power supply and damage internal components.
I like that feature. Good thinking Apple. Protecting my investment from bad electrical grids. But I don't like the fact my computer has a mind of its own where it decides when it wants to boot or when it wants to sit there and run its fans all loud.
I shut down Tues morn to go to work. I come back in the evening, it doesn't want to boot up. Instead of getting angry trying a bunch of times to turn on/turn off the computer, I leave my house all together and go and have a few drinks. I come home ,don't even look at my computer, and go to bed.
I wake up Wed. morning. Go to turn on my computer. Successful boot. It's running. Okay, I think, I'm going to get down to the problem. I read all the logs, not like I know every piece of info, but just to see what's happening. Everything looks fine. I decide to run the AppleCare CD Tech Tool. It says restart holding down C. I do that. When the gray Apple Logo comes up, all this writing about kernals comes up and it tells me to restart or shutdown. I shutdown and attempt to restart, same problem: no chime, red light on, and fans eventually spin loud. Now the CD is stuck in there. I'm going to take it to the Apple Store tomorrow to if these "geniuses" can figure it out.
(Just a side note: Apple calls them geniuses, but its hard for me to think some disconnected college kid with a bad haircut and questionable social skills knows what's up with the power supply issues of a computer; maybe I'm wrong, but you can run your diagnostics and look at the chart of what to do and all that BUT Apple needs to listen to the people)
I am going to get a UPS (uninteruptable power supply) with a clean sine wave output to curb the issue at my end. It's not my fault I live in a area that receives uneven power output. I live in Los Angeles. Summer is starting up and I think its going to be hot, so blackouts, power dips and sags are inevitable. I just don't understand why Apple hasn't considered this problem and fixed it with something:
A recall to change the power supply, Is it something on the logic board?, are they going to reimburse me for lost income (Ha, yeah right)
I really want to know how many people are having this problem?
From what I've heard, it is a common problem.
So I think we need a common solution.
If its so common, it must be the computer. We are all going to live in different areas where the power may vary. Not all of us have the consistent power flow of 1 Infinite Loop in Cupertino, CA. So if it is such a common problem, Apple needs to fix it.
I can't spend more than five grand on a super duper computer and have it wuss out on some power issues.
Its a loss of income and productivity to me.
I can't have that anymore.
Sometimes my computer turns on, sometimes it doesn't.
I bought my PowerMac G5 in April 2006, its been about a month and a half and I'm having these problems.
Thank you for your time.
If anyone else has been having this problem, I feel for you.
It was been very difficult for me not to curse in this post, but I have tried to extend the same respect to all that use these discussion boards to create dialogue, find help, and create solutions.
LETS FIX IT!

My macbook is extremely hot and the fan is worryingly loud, what is wrong with it and how do i stop this from happening?

For soem reason if I actually dare to use my macbook the fan kicks in and is so loud that I am unable to use skype or other voice programs without a headset because of its volume, also it gets very hot very fast, so hot that if I rest it on my knees it burns. I normally have it on a desk and the area is well ventialted. I have no print queues and rarely have more than two programs running at a time. Can anyone offer a suggestion of what is wrong and how I can fix this please? One of the main reasons I bought one in the first place was that they are so quiet when shown them in the apple store, but this is worryingly loud...

Thanks, it seems that it doesn't like to play games, which is a bit of a bummer as i bought this specifically because it was capable of doing that. To be fair, it is capable... I just need to get used to a sound like sitting by a washing machine on spin cycle... Wish they would make people aware of this in the Apple Store, its very misleading and not at all desireable.

Safari Update 8.14.14 causing fan to run loud?

I just did the update for Safari 7.0.6 on 8.14.14 and now it appears that my computer fan is running a lot louder after I did this update. I know that it is not the fan not working correctly or the vent is clogged because I am using Chrome right now to type this message and the fan is running normally. I am wondering if others are having problems with this new update and/or how to solve the problem of the latest Safari update causing the fan to run louder.
Any advice would be appreciated.

Extensions and plug-ins can increase fan speeds not just the browser itself.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
Check the fan noise. If it decreases, turn extensions back one at a time to test until you find the culprit.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.

SQL Server log generating minidump files every minute

Good afternoon.
Our SQL server recently started generating minidump files almost every minute.
I'm waiting on the final dbcc checkdb of the final database but all others have returned without error.
I've run the dump files through the debugging utility and have the following stack dump which I'm not sure how to interpret.
At this point, I'm not quite sure how to proceed, pending on the results from dbcc.
There are no other obvious errors in the event or system logs to cross-reference.

i agree with Erland. Run DBCC CHECKDB on the database. Most likely there is corruption in database.

Hy ,
My mac pro (SL 10.6.8) wakes up every minutes when I use wake on lan and I share one of my Hard Drive.
When I unplug the ethernet cable it doesn't wake any more so I suppose that some thing wakes it up on my network ( 1 printer canon MP620, 2 mac books, 2 iPads, 2 IPhones and 2 time capsules !) ...even when all these devices are "sleeping"
Any idea?

Finder in restarts every minute or two

I was updating software, via software update, when my computer crashed. I restarted, and finished the installation. But now, my finder quits out and reopens every minute or so. It disrupts all work. Especially my attempts for a frantic back up in case the harddrive has gone south. Does anyone have any thoughts on this one?
Any help would be greatly appreciated

Jon,
1. Since your computer "crashed" updating software use Disk Utility as specified in the Try Disk Utility paragraph of Mac OS X 10.4: About the utilities available on the Mac OS X 10.4 Install DVD. When you get a clean bill of health, restart from your Hard Drive and run "Repair Disk Permissions" from the Disk Utility application which is in your Utility Folder.
2. If those procedures do not solve your problem, find the com.apple.finder.plist file in your ~Library/Preferences Folder, drag it to the Desktop and then log out/in or restart.
3. If that is unsuccessful reapply the Mac OS X Update 10.4.5 Combo.
Let us know what happens.
;~)
