Portege R100 freezes - is CPU fan defective?

I'v had Portege R100s for a long time, perhaps 7 years, I'm down to my last one.
I just came back to it after eating and the XP screen was just frozen, no mouse movement, CntrlAltDel did nothing. Press and Hold the power button did shut it down.
Now I can boot it up, but it freezes again in a very short time, a few minutes. I'm guessing that the procesor fan has stopped.
Does tht sound right to people, is it a realistic possibility to cannibalise the carcass of my previous one and fit the fan into my current unit?
Thanks

Of course it could be related to the CPU issue.
If the CPU would not be cooled down properly then the system might stop to respond.
Are you sure that the cooling fan has stopped working?
If yes then the cooling module should be checked and replaced with the compatible one.
You cannot use any cooling modules. It has to be the compatible one.
But to be honest I think that the RAM modules should be checked too
In most cases an RAM problem is more realistic as an faulty cooling module
My old notebook stopped working because one of the RAM slot was faulty
I remove one module and the notebook worked using only one RAM module
However, I could not use it as I wanted and I bought new notebook.

Portege R100: fan and screen

my portege r100's fan is not working anymore and i wonder do the service change only fan or mainboard totaly...and my screen has 24 dead colour pixels what do i have to do
kind regards

Hi Murat,
In my experience repairers will take the fastest option for them rather than the cheapest for you. So if your fan can be replaced easily without changing the main board then that is what they will do.
With regard to your dead pixels the only real solution is to replace the screen.
I think this is a job more suited to a Service Agent,

Compaq Presario model SR5710F hangs/freezes when cpu cooling fan switches to higher speed

Compaq Presario SR5710F with AMD Athlon X2 4450e dual core micro-processor - after the desktop has been on for a little while, I can hear the cpu cooling fan switch to a higher speed. As soon as the fan changes speed, the PC locks up. Power off/on is only option to recover. A precursory inspection did not reveal any noticeable build-up of dust/debris around case fan or cpu fan. Any suggestions?
This question was solved.

Hello DTCothren,
You state whenever your CPU fan goes to a higher speed the computer locks up, is that corret? I will try to assist you with this issue.
I would recommend you open up the hardware diagnostic tool on your computer, and run a full system test. This test does take some time so just allow it to run. If you not sure how to locate the program have a look at this document.
Please respond back at your earliest convenience.
Thanks

Portege R100 - Random Blue Screen of Death (IRQL not less or equal)

Hi,
I've been getting random "Blue Screen of Death" screens in the last few weeks. The error is "IRQL not less or equal" and it's performing a memory dump every time. If I get the error and try restarting the laptop after, I usually get the same "Blue Screen of Death" screen when booting.
I didn't install any new hardware lately. Last upgrade was about a year ago; upgraded the memory. I've tried replacing the RAM with a spare one I had and I was still getting the same error.
I didn't install any new software in the last weeks that would coincide with this error.
I'm monitoring the CPU temperature and I doesn't go higher than 48 deg Celcius.
I'm not an expert but I would assume this is purely an hardware problem ? Since I rarely hear the CPU fan, I thought it could be the CPU overheating.
But even after making the CPU fan run at 100% using a freeware called "Speed Fan" I was still getting the same random "Blue Screen of Death" screen.
I would really appreciate any feedback and help. I really like my R100 and would like to fix it.
Mark.

Hello, I have a Portege R500 and I am also too having this error message. I was getting a blue screen when loading the pc advising of a memory dump issues.I ahve replaced the ram inside the laptop and this has failed to resolve the issue. I am now having the error, IRQL not less or Equal everytime. I have run a memtest86 scan and this did show up possible memory issues. SO I have replaced the memory chip again. Still showing up as memory issues.
You have mentioned this could be a cpu or memory controller. If this is the memory controller can this be replaced? or would a motherboard replacement be the best option?
I have not tried a re install of windows 7 32 bit as yet, As the memtest86 program has identified possible memory issues. Please can some one advise if replacing the cpu and possible memory controller would resolve this. Memtest log available if wanted.
Regards
John Powell

Pismo Freezes-Up...Fan Problem???

For the past week my Pismo has been freezing-up after 30-45 minutes of web surfing (its primary use). Suspecting the problem might be an overheating issue, I elevated it a few inches off the table; this didn't solve the problem. Usually the fan switches on after 90+ minutes of web surfing, but I don't regularly use the Pismo that long at one time so I usually don't hear the fan (and I haven't heard the fan working in a while). My Pismo definitely gets hot after 30+ minutes of use, so I'm thinking it is overheating (leading to the freeze-ups) because the fan is broken and needs replacing.
1) Do you think the freeze-ups are heat related?
2) If yes, is the fan not switching on the problem?
3) How hard is it to replace the fan? I can change the usual things (items directly under the keyboard - hd, ram, wireless card, etc.), but from searching on the web it looks like replacing the fan requires, among other things, removing the screen (which I've always heard is hard to take off and put back on) and then taking off the bottom of the Pismo.
Thanks.

nomad,
When it freezes, can you immediately restart, or do you have to wait a period of time before it will start? If it does restart immediately, will it run another 30 minutes?
You mentioned it is freezing after 30 minutes, so if it normally takes 90 minutes before the fan runs, you really don't know that the fan is dead. These fans seldom run, so it is unlikely (but not impossible) the fan is still quite healthy.
There are many reasons for your Pismo to freeze, so it is worth looking at them.
1. Marginal RAM: You may have memory that has developed an intolerance to heat. If you have two modules, each at least 128MB in size, you can test each individually.
2. Poorly seated microprocessor card: The Pismo has a microprocessor card that is difficult to seat. If it has been removed for memory or HD changes and not properly seated, it can slowly work loose over time and cause the freezes you are experiencing.
3. Poor thermal transfer between the heat sink and the top of the CPU: If the heat sink has been removed, the thermal transfer pad between the two items should be replaced since it usually tears resulting in poor heat transfer. The CPU may heat enough, locally, to cause a freeze before the fan starts.
4. Circuit boards: You may have developed a hairline crack in one of the boards which opens when heated.
I would try these possible fixes:
- If you have the Apple Hardware Test CD that came with new Pismos, give it a run in the extended mode. See if it can generate the freeze and produce an error message.
http://docs.info.apple.com/article.html?artnum=112433
- Reseat the microprocessor card; use Apple's instructions for installing RAM in the lower slot...it will describe reseating the microprocessor. When the top memory module is removed, press down VERY hard where indicated by the instructions.
http://docs.info.apple.com/article.html?artnum=50028
- Do you still have OS9 installed? If so, download Newer Gauge PRO and run the extended memory test.

CPU fan spins up for no reason and never spins down

I'm having problems with my new and otherwise immaculate iMac Intel 2.4 GHz. The CPU fan often spins up to 3500 rpm for no reason, even when left idle.
There are no processes running to justify the noise (no Spotlight indexing or anything) and the temperatures are as low as can be.
I have tried resetting PRAM and SMC many times to no avail.
Usually putting the Mac to sleep and waking it up slows the CPU fan down again, but it will go nuts at 3500 rpms sooner or later.
Once the fan has spun up to 3500 rpm it never spins down again unless the iMac is reset or put to sleep and woken up again. Even when hours of useless fan spinning has left it freezing cold.
SMCFancontrol won't help as it can't slow down fans only make them go faster.
Apple Support suggested I'd take it in for repairs but I'm reluctant as this smells like a Leopard/Boot Camp Issue from what I gathered on the boards. Also the repair service in Denmark is outsourced to third party repairers of questionable quality.
Any ideas?

I got my iMac back from repairs. They said they couldn't reproducere the error which might be as it at times appear very sporadic. The fans began to spin within the first day of use after I got it home though.
It seems that more and more users on the boards experience this problem. My theory now is that this must be a software issue as it usually begins once people update to Leopard 10.5.2.
The problem manifests itself like this:
The CPU-fan will start blowing at 3500 rpms for no reason (CPU-load and temperatures can be as low as can be.)
The CPU-fan will never slow down again by itself. Even after hours of unnecessesary spinning has left the Mac freezing cold.
Putting the iMac in sleep mode and waking it up again will temporarily slow down the CPU fan down to the usual 1200 rpms (usually for about 10 mins).
Resetting PRAM and/or NVRAM (SMC) will not help.
Installing SMCFancontrol will not help as it will only let you speed up the fans further - not slow them down.
So now I really hope Apple will address this problem with a new OS X release soon.
Still, if anyone manages to fix this problem with a hardware replacemnt please let us know.
Cheers, Jez

Portege R100 won't boot from the HDD - missing operating system

Hello,
I have a Portege R100 that won't boot from the HD, I get the message "missing operating system".
I don't have a compatible CD or floppy driver, I just have a 1.8 inch case for the hd, it works, i also have norton ghost 2003 installed in another computer (a toshiba satellite A45).
I tried to recover the disk using norton and the ghost image in the recovery cds but it keep asking for a password.
I would like to know if there is a way to use the recovery cds with norton and the usb driver and avoid the password screen (or where can I get the password?).
Thanks!

Yes, I know that the recovery cds are password protected, that's the password I'm talking about.
I'm not trying to boot from a USB stick, I'm using ghost 2003, this way when I reboot the USB device is recognized as a second hard drive.
I have the option to use the cds to recover from the ghost enviroment but I would need the gho password.
What I would like to know is if there is a command line to force the cd to ghost the second driver instead of the first.
I'm not a great fan of norton ghost but I don't have another option, all cd drivers that I have are incompatible with Portege R100.
Thanks,

Cpu fan stuck at max speed

Out of nowhere, my computer (early 2006 20" Intel iMac) started making huge fan noises. The iStat pro widget shows that the CPU fan is blowing at 3600 rpm (apparently the max), and the other two fans are normal. CPU usage is minimal, and CPU temperature is low (30-40 degrees C), so there's no good reason for the fan to go to the max.
I've tried (several times) to reset the SMC, but it doesn't help. A couple times over the past five days, it's gone back to normal, but then it soon goes back to max.
Anybody experienced anything like this? Any suggestions?
Thanks in advance,
Neil

I have the same problem,
I know a lot about computers (for not a professional) and after doing anything i can without opening the case,(SMC reset, Vram reset, safeboot and starting on verbose,Apple hardware test)
In my specific problem the facts are
4SNS/1/40000000:'TmOP' from apple hardware test
Cpu Fan: 3604rpm (really high) this is the logic board fan
the other 2 fans are normal
Cpu tmp: 28 C (low)
GPU diode 127 C (ridiculously high - no tmp variation) from Istat pro
Memory controller 127 C (ridiculously high - no tmp variation)
all the other temperatures, as the cpu ,are a little bit lower than normal which is normal because of the high speed fan
that means logically that the system is reading a 127 Celsius tmp in these places
and the fan is responding right
So the tmp sensor is sending a false tmp
there are 3 sensors this one is on the logicboard and you cannot change it
i went to a certified apple service provider and we open the case together,
as i wanted to be there.
I hoped with some dust cleaning or something position related we could do something but no, after checking every possible solution,
needs a logiboard replacement that he (like me) did not recommended (very expensive)
Other than the fan noise there is(until now) no other symptom, in OSX or XpPro
so I'm not going to pay about 700 euro (for everything) for this machine
I'm positive (i checked it myself) that there is nothing hot inside, just the sensor circuit is stuck at these tmp
If the the fan dies sooner its much cheaper and i can even replace it myself
I 'm very sad and disappointed with this solution but what can i do?
It is just 2 months after the warranty! and i know that this is a logicboard defect
the ironic thing is that before that happened i was thinking o upgrading the Cpu 2.0CD to a 2.33C2D (yes you can, if you really want) but now i 'm going to leave it like this and sometime buy a new thing (not an imac again!) a mac pro if i am richer or a decent PC
I really like macs and everything, but the compact feature when the time comes may have a compact problem!
the other funny thing is that they offer me a job in the Service place but i am an artist
Good luck and i hope someone finds a solution or something else

Satellite L670 cpu fan noise

As I sit in front of my new L670 laptop, from the left end of the keyboard comes a frequent whirring up and down sound that i'm pretty sure is the CPU fan
(not the HD).
How much of this is too much? I find it disturbing.There's no sound like it from my 1 year old Toshiba. The temperature of the room is a constant 20degrees, so it isn't overheating.
And it does it even when sitting idle with only the Windows7 screen up ie no software activity going on at all.
I'm worried this is a defective computer. It's 2 days old (to me) - purchased brand new. Still could take it back.
Grateful for any thoughts.
L

I also have a Satellite L670 and have the same fan problem.
I bought this laptop 1 month ago and the problem was there from the begining. I have already set all the possible parameters to lower power consumption, and I set the CPUs to run between 1% and 50% of their maximum frequency. The problem is still the same. The problem does not come from the user nor the settings, but from the laptop itself.
IMO the problem is that this laptop refuses to set fan speed at e.g. 25%, 50%, or 75% of its maximum speed, depending on the temperature. The fan is either off (silent) or runs at full speed (too noisy). That is NOT a normal nor optimal behavior and Toshiba should fix it (BIOS update?).
I tried speedfan but it could not change the fan speed.
My other laptop, a cheap brand machine which I have been using almost everyday for over 5 years, is much quieter. When using a lot of CPU the fan will indeed make some noise, but that seldom happens in normal use and most of the time the fan runs at low speed and is barely noticeable.
Any solution to this problem would be greatly appreciated!

K8N Neo 2 platinum freezes. NB Fan problem ?

Hi all,
I've had a Neo 2 platinum for almost 3 years now, which was running absolutely good.
Then, I began to have random freezes on the Windows desktop (not with games).
I thought I ought to clean up a bit the beast's inside as dust could be the problem.
After cleanup, same crashes, but even more and more often, to the point last WE, it was
freezing at BIOS level, before booting. Now it seems I can no longer boot (not even the startup
beep of the mobo is heard !). Only the CPU and case fans spin, nothing more ....
My question: since I've noticed the NB fan was blocked (probably died like the countless others), could it be because of that I can no longer boot, even with a cold system ?
I'm trying to guess what part I need to replace, PSU, fan, or mobo ...
Setup: AMD64 dual-core 3800+
K8N Neo 2 plat.
2 GB of RAM (no recall of the mark)
Antec 450W PSU
NVIDIA 7800 GT GPU

Quote from: Fredrik on 02-December-08, 05:34:35
With the NB fan having a problem I wonder if the processor fan might be dusty.
450W Antec sounds like one that came with the case. Is that so?
Well, the CPU fan was dusty, before I cleaned it, yes. Now, it's clean, and is definitely not the problem.
The 450W PSU was with the Antec case, yes. I was kinda suspecting it to be the problem, since it decided to die after just below one year of the system's life (it probably grew fed up of all the power cuts we have in the winter, here, thus I RMAed it and put an MGE UPS), but I think I can rule it out now. All equipment are just booting OK, until disk query is issued. That + the dead fan makes the cause for me ...

How to reduce cpu fan speed just by hardware?

Hi,
I have a K8N Neo4-F, AMD3200+ and "arctic cooling freezer 64 pro" as cpu fan. The rpm range of this fan is from 300 to 2200. I use "cool n' quiet" and "Smart CPU Fan Target with 40°C" as bios setting. When the cpu is idle ( ... just doing some typing or so on ...) it has a temperature of 32°C and the fan has ~950 RPM.
I think the fan speed is to high for this cpu load (< 5% and 1000Mhz CPU Clock). My expectation in this szenario is to have the cpu fan speed near the lower bound (300 rpm), but I don't know how to manage this (with just bios settings) ... any hints?
Thanks a lot ...

Quote from: Kwea on 12-January-06, 22:29:54
My point was you did what D.O.T. is supposed to do without using it.
Of course it's point is to auto-overclock the system to whichever degree it's set at. The problems come in because a lot of the settings it uses aren't always compatable with a lot hardware combinations. That's why it's best to come up with your own OC settings that are stable with your parts.
It's just like how the Nvidia/ATI speedup option seems like a good idea, but works poorly in practice.
Both are more useful to the marketing dept. in having more "why tech" features available to print on the outside of the retail box than they are to the end user.

PB Alu and its Cpu-fan

This might be my last attempt to solve the problems with my dear pb. I bought an used powerbook 1ghz for about 6 months ago. Everything works excpet one thing, the cpu-fan (i guess). I can work for hours with cpu-temperatures below 60ºc. But when I do more intensive tasks, such as gaming, music production the cpu gets too warm. The fan is living its own life, not too concerned that its cpu-buddy is overheting. It activates sometimes, but far from everytime over 60º.
The result is a total system freeze, not a kernel panic with that dimmed screen with shutdown info, it simply just freeze . It's drivning me nuts. I would be better off with a non working fan than a fan that works occasionally. I've tried most of the tricks and solutions, p-ram, nvram, re-installation.. etcetc.
If someone has a feeling what the issue could be, and a possible soultion, please tell me. i'm greatfull for all reflections.
My system is 10.4.5, PB ALU 1GHZ 768RAM 60GBHD.

X48 CPU fan fails to spin

ystem specs:
ThermalTake Tsunami Dream + ThermalTake 850watt PSU
MSI x48 platinum motherboard

BFG 9600 GT OC
ArcticCooler Freezer 7 Pro
Problem: the CPU fan simply does not want to spin. when booted up, there is no sign of life from the fan itself, even if i go into the bios, disable, or enable the smart fan control, i still get nothing. when enabled i have set it at 40*c, while the CPU temperature is at 50*c, and yet there is still no life from the fan. it is plugged in correctly etc. HOWEVER, when i bypass the motherboard and draw power directly from the power supply, or a 9v battery, the CPU fan spins with no problems, and remains at a constant temperature of 50-53*c. i have read a few article's while googling for a solution suggesting that there isnt enough voltage/current going to the fan itself, im just wondering if there is any way i can change this through the bios, as i have not been enable to install and Operating system in fear of the CPU frying while i am doing so, which would mean i couldn't try controlling the fan in a more software based manner.
if anyone can shed some light on the situation i am currently experiencing it is much appreciated.
//Regards, Griff.

Yea, Freezer 7 pro (64 is the AMD version).
Just noticed something which i completely missed before, is that he had stated that there is no sysfan3 header, yet it listed on the manual and should be to the bottom left of the cpu socket next to sysfan 1 (3pin)
Im wondering if he has a v3 board as the pics im finding of v1 show the sockets as per the manual but i just found a pic of a v3 board with only the 1 header in the right area.
Elliot, can you check if, where the heatpipes turn towards the top of the board, how many header points are there, and between the pci and pci-e sockets are, what the text says. does it say X48 platinum v1.0 or v3.0
EDIT!!
nope, must be a V1.
v3 is the X48C

CPU Fan Question

I have been experiencing "freeze up's" lately and I did some research here to troubleshoot the problem. I performed a thorough dusting and cleaning of the interior and the problem seemed to go away. Needless to say, after 3-4 days of problem-free operation, the "freeze-up" problem returned.
I have discovered that the CPU fan is not operating. Presently I'm using the G4 with the door open and a desk fan directed at the CPU heatsink. Operation appears to be back to normal.
Question- Should the CPU fan be constantly operating or is it thermostatically controlled on-off?
If the CPU fan needs to be replaced, is there a suitable substitute CPU fan that will enhance the cooling of the CPU?
My model spec's are below.

Hello Carpetbagger,
I thought my QS 2002 800 MHz (with a dual 1 GHz cpu) was running a bit hot, so I went looking for fans that moved a bit more air. Evercool makes one, but I finally settled on a Sunon PMD series - PMD1206PTB1-A - which cools the beastie right down. (It also sounds like a leaf blower) Price was less than $10, less than $15 with shipping, although I may have had to buy two (just an excuse to buy another Mac). There are several other PMD Sunon fans that would seem to fill the bill even better - increased air flow, but fewer RPMs and less noise - but they were available in quantities of 100 units (@$6 ea).
The KDE 1206 Sunon fan is one of several fitted as standard, and should work as well as it did when the QS was new. It, too, should be available at under $10.
It's a fairly common fan size - 60mm x 25mm - and has many applications, so if you search Google for fans and distributors you should find out more about availability than you ever wanted to know.
http://www.PCtoys.com/ is a source for both the KDE Sunon and Evercool.
Remember, a cool Mac is a happy Mac!
