Fan noise & Battery
Hi guys....
Recently my macbook pro early 2008 (intel core 2 duo, 2gb RAM & 250gb Hard Disk) wouldn't switch on...
I saw a youtube video (http://www.youtube.com/watch?v=pPBN374PM7E) which told me to:
1) Get the battery out.
2) Hold the power button for 10secs.
3) Keep holding the power button and insert the power cable.
4) Do this for 10 secs.
5) Then release and count again till 10secs, but the power cable still in.
6) Insert the battery again after 10secs count down.
7) The click the bottom on the battery.
8) It switched on
Though, it made a loud noise of the fan and no battery was detected even though I have a battery plugged in.
Please can you help its urget!!!!
Woah.......that video was made by a 10 year old. Yeah, no on that.
noisy fan reasons:
A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
C: fan rotor is going bad and making a whirring or buzz noise (rare).
D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
A and D are normal
B and C are not.
If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either sieze and/or die.
Make appt. with apple for diagnostics, however WHILE you have it apart, clean the fan good. compressed air and Qtips.
Its likely your fan rotor is dying.

Problems with new Yoga 2 Pro (battery, fan noise, yellow, screen orientation, on-screen keyboard)
I purchased the Yoga Pro 2 on Thursday October 17. I love the computer for so many reasons, (especially since it replaces my 4 year old Compaq that was 6.5lbs!) however, I am also having a few issues with it.
It is the i7/8GB/256GB model from BestBuy. I am experiencing the same yellow issue as is mentioned by many on here. I didn't realize it, though, until reading these forums and then comparing to my old computer and my ipad and iPhone. A little disappointed, though it looks like Lenovo may be working on a solution.
But the real reason I originally came to look at this forum is because of 2 things: my fan and battery.
The fan (on the right side of the keyboard) is always on! I didn't expect this, and am wondering if mine is a lemon or if others are noticing the same thing. It's pretty noticeable, especially in a quiet room. I was showing off my new computer to a friend and the very first thing she said was that it was loud! She was using a MacBook pro, which wasn't making any noise at all.
The second thing is the battery... I am attaching 4 photos all taken within a few minutes of each other. If you cant see them, they are all of the battery meter on my screen. I am listing the time of day (to show how much time passed), percent remaining, and time remaining:
10:04 (88%) 306 hr 15 min
10:05 (88%) 8 hr 48 min
10:09 (86%) 4 hr 54 min
10:29 (81%) 5 hr 12 min
I feel like my computer just cant make up its mind!!
Another issue I had... I turned on my computer to show it to a friend (same friend who said it was noisy) and the screen image wouldn't flip when in any of the modes. This means I showed her the stand mode with an upside down image. Even in tablet mode I couldn't get it to flip. I turned the computer off and then on again, and luckily it decided to work, but it was frustrating, and I hope it's not something that becomes an issue.
Also, when I have the computer in tablet mode, the keyboard automatically pops up when I click somewhere to type... but this doesn't happen in stand mode or tent mode. Is this normal? I would have thought that the keyboard would appear in any of those modes, since the real keyboard is not accessible in any of them. And of course now that I am testing it out while writing this, none of the modes (including tablet) is having the keyboard come on screen. Of course, I know I can always choose the icon on the task bar to bring up the keyboard, but it would be nice if the computer did it automatically since it knows there is no other keyboard accessible in those modes. Is this an issue anybody else has had?
I really do enjoy using this computer, but some of these issues really need to get worked out if I am going to keep it. I'd love to hear if anyone is experiencing anything similar, and if there are any good fixes!I just got a Lemontine Yoga 2 Pro i5/8GB/256GB from lenovo.com and the silver one from BestBuy in the same configuraiton. The silver one has no issues except for the crazy number of hours remaining on the battery which is fine, doesn't bother me. The fan noise is very quiet, and you can only hear it if you put your ear up to the vents in a quiet room.
Now the Clementine one...It was heating up pretty good. I put my ear to it on many occasions and can hear nothing at all, the fan is either missing LOL or doesn't work. I had an issue where I left the thing on for 4 hours, but sleep is configured after 5 hours. When I tried to use it, it showed me the screen brielfy, then blank. Tried hard reset, called Support, nothing. Support says its dead. Ok, an hour later, it turned on. I'm guessing it was too hot and was in some mode to protect itself, like a smartphone that is left out in the sun for some time, it won't power on till its cooled down.
I'm still in process of trying to get a hold of Lenovo to swap it, but since they no longer sell this configuration, I doubt they'll be able to get me a new one.
The silver one from BestBuy us solid though, love it, best in class in my opinion...actually got it from Future Shop sorry...from Canada, but they're essentially the same store. -
My mac mini only shows a steady power light and fan noise when powered up. No video or sound and no commumication with wired keyboard or optical mouse. Tried replacing internal battery and resetting PMU/SMC but nothing seemed to happen. Any suggestions? Many thanks! Richard
You've already done the two things I would have suggested.
If your Mini has an internal battery then I assume it's a G4. That means you've gotten a lot of good years of service from it, and it's old enough that it's certainly not covered by AppleCare anymore, and it's probably not worth spending money trying to repair it.
You should be able to tear it apart using instructions from ifixit.com to get the hard drive out, and then put the hard drive into a nice USB or FireWire enclosure (I like the ones from Other World Computing, macsales.com) so you can transfer your data to a replacement Mac.
I hope someone has another suggestion for you. -
Problem with fan noise and battery on g510
I bought an new lenovo g510 ( core i5 4200m and amd r5-m230 ) from 3 days
and notice that fan has a noise most of the time and when i check the battery wear level on hwmonitor it is has 1 % wear level so why i got these problem and my laptop is bought from just 3 days !!!!!!Hey. Really sorry for late answer. i got same model (but i7 , r7 m265 )
For the fan noise ; check out gpu and cpu temperatures . clean the fan dust with power manager program. and update drivers.
for the battery , %1 wear is nothing . only affects 1-2 mins . battery has internal smbus battery fuel gauge and it automatically calibrates battery full charge capacity. but you can manual calibrate fcc with power manager. we are very lucky because on some hp ,samsung etc laptops , battery comes with %10 wearage (like my old laptop).
you post this message 6 months ago. if your battery wear is >%15 now , send battery to service. they will replace a new battery. if battery wear <%10 , your battery is normal -
Fan noise coming from the macbook air, and battery won't charge?
Brand new laptop and now there is a very loud fan noise coming from the computer when i opened it up this morning.

T410 - fan noise whilst battery is charging
Hello everyone,
I own a T410 for about a month now and still have fan noise problems. They only appear when I charge the battery. The fan speeds up and get annoyingly loud just after I plug it in. It's like the cpu is running 100%, but it is not! When the battery is charged or I pull the plug the fan gets silent again.
Also the notebook does not get hot. Everything seems normal, except for the noise.
Is there a solution to this problem? I would be very happy because it's very annoying when I am at University.
It is a T410 with Nvidia Optimus. Preloaded OS. Newest power manager and nvidia drivers.
Thank you,
semjorka@semjorka,
Welcome to Lenovo forums, could you try updating your BIOS and see if it helps (do ensure reboot first before flashing the BIOS). Also update all your software using ThinkVantage System Update and Windows Update as well.

Extreme fan noise on Retina Macbook Pro "15 2012
My Macbook runs very loud without intensive apps open when I connect it to a Thunderbolt Display for over an hour. I have tested this to great length, it doesn't matter whether it's photoshop, microsoft word or google chrome that's running, it's the fact that it has to power an external display.
I have taken it to Apple Support, however they perform their cooling system tests in 18 degree airconditioning so it's impossible to demonstrate how loud it gets at normal room temperature.
I presented this problem twice within my warranty period, but Apple will simply do their test and deny any problem as the fans barely start up in the cold test environment. They did say that if my laptop overheats and becomes damaged, they will cover the damages because I made the complaint within the warranty period. Now my warranty has expried (I simply didn't have time to waste taking the computer to Apple again within the last two months).
Is there anything I can do to get my laptop fixed? I'm pretty sure the graphics card was faulty to begin with as it cannot take the load of a Thunderbolt Display over an extended period. There are so many documented cases of issues concerning fan noise and overheating with the 2012 rMBP, is Apple not going to do anything about it?!High CPU usage will make the fans run faster (luder) you can try a SMC reset:

Follow directions for a battery that should not remove yourself. Also have the Apple tech make sure you do not have a bad temp sensor. -
Thinkpad Yoga 12 20CD extreme fan noise
Hi,
Last week, I had my Thinkpad Yoga 12 serviced, as it didn't boot anymore. The whole interior got replaced. Since then, the fan noise is really unbearable. It was the same when I initially bought the machine, but then, a BIOS update (don't know which anymore) fixed it. It's a loud high-pitch noise, like a whissle.
I need urgent help, my collegues are complaining of the noise.
Best regards,

Well here I am on the new thread as well - and like heck the issue was resolved on the old thread. As mentioned before by myself and others on the other thread, I would update the BIOS, the fan would work for a while, then it would stop again until I updated the BIOS yet again.HOWEVER, thinking on this, and a variety of other problems I've been having with the TP Yoga (a whole lot - such buggy software), I remembered from my T61 days that the Lenovo System Update software is pretty hit and miss with finding updates. So I went to the Lenovo downloads page for the TP Yoga and indeed found a lot of software not passed onto me by the System Update.Amongst these was (TA-DA !) a utility "Lenovo Fan Test for Windows". I thought it would be useful to install in any case to test if the fan was operating properly (it was not part of the standard suite of diagnostic tools provided on my computer).Anyway since I installed it my fan has worked !!! - but only when my computer is plugged in, though this I believe is because I am using Lenovo Power Optimized (Lenovo Power Manager was another software on the site not provided to me via System Update) which I believe relies on passive cooling (throttling back processor) when only battery power is available. But now TpFan works all the time, though only in smart mode, and when I plug in the power to stream a video the computer doesn't reach boiling point and then shut down.Interesting. My fan diagnostic comes up as unavailable... -
My Powerbook G4 make some fan noise. Please help!
From last night my PowerBook G4 makes fan noise. It sounds like fanning sound when the computer is overheated during hot summer. But my room temperature is aroung 70 degree.
It happens when I open many windows but I need to open them to trade some at TDamertrade.com site. To check other sites too.
I would very appreciate any suggestions I can try to fix this fan sound.It is possible that you are having these issues because you installed the MacBook Pro SMC Firmware Update 1.3 by mistake:
*http://support.apple.com/downloads/MacBookPro_SMC_Firmware_Update_13*
I remember when this was released that PowerBook G4 owners were seeing this update via their Software Update application. Sometimes I just install those updates without closely reading what they are for exactly. Anyway, I know it says for high work loads, but you would be surprised how easily the fans will turn on high just from simply web browsing.
I suggest that you first try resetting the PMU:
*If the computer is on, turn it off.*
*Disconnect the AC Adapter and remove the computer's battery.*
*Press and hold down the power button for 5 seconds and then release the button.*
*Reconnect the battery and AC Adapter.*
*Press the Power button to restart the computer.*
If the above works for you (great), if not, try resetting PRAM and NVRAM:
*Shut down the computer.*
*Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.*
*Turn on the computer.*
*Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.*
*Hold the keys down until the computer restarts and you hear the startup sound for the second time.*
*Release the keys.*
If the above works for you (great), if not, try archive and installing:
*http://support.apple.com/kb/HT1710*
If the none of the above worked for you (not so great), do the following:
Go to your closest Store next week after making an appointment with a Mac Genius:

I hope that I helped you solve your problem, but do post back if not and I will help you narrow down what is going on even further. Personally, I feel that I am better than going to see a genius because most of them are just trained for Intel machines these days out in CA, where as, I know all the way back to PPC and Mac OS 7. Best of luck. -
Hi, I just recently bought a Lenovo S10 and am loving the new system, but I can't seem to get over the unbearable fan noise.
Is there any way I can change the temperature at which the fan runs? The fan is running even when I'm just browsing the web which is completely unnecessary because the computer's only around 40C which is still really cool, although maybe not for a netbook. Normal laptop cpu's can handle up to 80-90C so I don't see why it would be necessary to keep the fan on when it's at such a low temperature.
This is just an issue for me because I want to bring this netbook to class without bugging everyone with the fan's constant noise. It would also help to increase the battery life of the system which would be nice since it only ships in 3 cell at the moment.I also have this problem.
In performance mode the fan stays on about 90% of the time, even when it is doing nothing at all (cpu 0-2%).
In balanced mode it stays on about 70% of the time and sometimes is on while doing nothing (cpu 0-2%).
When in the lower power modes it stays on while browsing the internet but if you do nothing it usually stays off.
It is not a loud buzzing noise it is just the fan staying on when it should not.. The laptop is very cool, hardly even warm to the touch, even when playing HD videos or other CPU intensive things.
I wonder if the new Bios update fixes this problem.
Any help would be appreciated.
Edit: Maybe not so cool when playing HD videos (65-70c) but when using it normally it stays around 50-55c. I'm not sure what the fan is set to turn on at.

I had the same problem, one of my fans was making a loud noise even when my computer was just idling. It can occur because you dropped the computer, thus damaging one of the fans, or the fan broke down partially. I took mine to the Apple genius bar and they ordered a new fan for me and installed it in under a week (all covered by warranty). This is likely a hardware and not software issue, the only way for a fix is taking it to a genius bar. -
Hi everyone;
Since I replaced my hard-drive, I've noticed 2 things:
1) thinkvantage button does nothing
2) My cooling fan is always on. I've read the posts saying to shut of wi-fi, change to dynamic setting, remove access connections; I've done all of these, to no avail.
Before I replaced my HDD, this was the quietest machine, now its pretty loud, so perhaps there's a relation, here. It was quiet right after I replaced the drive, but after I ran some tasks using the max performance setting, the fan just won't quit.
I used the rescue and recovery software on an external usb drive to transfer the os, ect, onto the new drive, which is a Seagate Momentus 500gb 7200.
Any ideas?
Solved!
Go to Solution.So, I swapped the hdd, and the stock runs quietly.
The problem is that the fan at the HDD runs at different settings with the stock HDD, and only at maximum with an aftermarket (at least this one), creating much noise, and drain on the battery. I don't know if theres some type of protocol between the hdd and the powermanager to control the HD fan; if so, it doesn't communicate with mine.
Which sucks, 'cause I need the extra speed and space, but I don't want the noise/ battery drain.
I wonder if the others who had the fan problem also upgraded their drives.
If this is the problem, Lenovo ought to fix it, as HDD's do fail, and eventually everyone will end up upgrading at sometime (unless they get a new computer). -

I did reset the pRAM like is said to do for the Macbook on one of these posts - removing the battery and pushing the start button... however it is still going... seems to be worse when running bootcamp and Vista -
Other possible solutions?Look under Utilities in the Applications Open Activity Monitor. Then you can see what applications are using the CPU the most.
The fan usually runs faster when you are using CPU intensive programs. This allows the heat to be controlled. Even if your not using the computer but applications are running they are using the CPU. This is normal for most computers.
The fans noise will fluctuate depending on need, this shouldn't be anything to worry about. When I watch MLB.TV my fans RPMs will get up around 6000 and the temp will be around 80º C. For most other programs the RPMs run between 1500 and 3000. -
Fan noise after an hour of use
I was installing a package which took approx. an hour. At the end of the hour, I could hear the fan noise. That's the only time I have heard any noise (for that matter). Is that normal. I have a Mac Pro 15" Retina. Thanks!
This may help explain the fan's operation: Learn about the fans in your Mac
After installing a package Spotlight activity increases, and it's normal for that to cause temporarily elevated temperatures. The fans should quiet down in a few minutes.
If you suspect something abnormal read: Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
