Lenovo G560 CPU FAN stop then overheating

Hello i have lenovo G560 after i turn it on a few seconds fan working then definitiveli stops and cpu go overheating and notebook go stutdown. I try to change CPU fan but issue is there still. Sorry for my poor english. Can anybody tell my what i want to do?

hi deadbiker,
Overheating problems are commonly caused by evaporated or dried out thermal paste or dirty cooling fan. Since you replaced the fan, I recommend you remove the heatsink and re-apply a thermal compound on the CPU and GPU (if applicable). See page 41 on the Hardware Maintenance Manual on how to remove the heatsink.
If the fan still stops and the unit overheats and shuts down, the CPU might be throttling or might be faulty already. I recommend you send the unit for service (either a local repair shop or thru lenovo since they have diagnostic tools to check the unit out). Support phone list here.
Hope this helps.
Cheers

HP PRO 3400 Series desktop won't boot CPU fan starts and stops , no video, no beeps

I have the above computer with an i3-2125 CPU, Windows 7 Home Premium 64 bit, and a 300GB Seagate Hard drive. I've had it for about 2 years and been working fine. It started acting up about 2 months ago. It would lose the date and time. I checked the battery, and it was OK, so I kept using the computer. Then on 9/15/2014 it hung on "Starting Windows", I did the following:
1. Ran the built in HP diagnostic on hard drive and memory and they both passed.
2. Tried to go to last known good configuration and nothing happened.
3. Noticed the date and time were off, replaced the battery, nothing changed.
4. Tried another hard drive from another HP PRO 3400 Series and it would boot up but could not set date in bios.
5. Tried all kinds of things but could not set date in bios.
      a. Bios date read 48/00/0048 after removing and replacing battery.
      b, Tried to reset date to 9/16/2914 and it gets 56/00/0051
6. Then it wouldn't boot at all.   So now when you turn on the power, the CPU fan starts and runs for about 1 second, then shuts off for 4 seconds, then starts and runs for another 1 sec and it does this continuously. There is  no video and no beeps and no difference when all memory is removed.
7. I removed the power supply, and checked voltages. It appears to be OK.
8. I removed the motherboard, and inspected it- saw nothing obvious.
9. I connected the power supply to the motherboard with nothing else connected to the motherboard, and I get the same thing. CPU fan starts then stops continuously, no video no beeps.
10. I am thinking it is the Motherboard, but I sure could use some suggestions as to what to do next.
Thanks

Cpu Fan Problems

Hi everyone, I am having some issues with my desktop. I have an HP Pavillion p6710f and just recently my cpu fan stopped working. I thought at first that it was just the fan itself, so I bought a fan from Best Buy and installed it in my computer. After encountering the same problem with the fan not turning on when I started the computer, I think that it might be the slot in the motherboard that is the problem. I bypassed the motherboard outlet by plugging my cpu fan directly into the power supply. That works but my desktop still thinks there is no cpu fan plugged in because it is not in the normal slot. I went into my desktop's BIOS to see if I could control the cpu fan settings there but I did not find anything.
If anyone can figure out what is wrong with my fan sensor (possibly need a special kind of fan) or how to bypass my specific computer's cpu fan settings please let me know. Thanks!

yeah i cleaned it today
thinking of getting a new one as u suggest
was wondering tho might it be the power supply?
thanks for the prompt reply

Lenovo G560 not booting. CPU Fan 100%. No output on screen or VGA

I have a Lenovo G560
When I power on, the fan is steady for the first 5 seconds, then it spins faster and stays like that. No output from the screen at all.
External VGA does not present any output either. HDD doesn't spin and nor does the light turn on. Removed and reseated memory modules as well as HDD. No change.
Purchased a replacement LCD screen as the current one was cracked the when laptop hit the floor! Therefore I'm thinking something's completely screwed the laptop up or is it a case of a loose connection.
Next thing I was going to try was to disconnect the CMOS battery which would hopefully reset the bios - Can anyone shed any light on this? I believe it's under the keyboard and I have the remove the top chassis. I know that it may be soldered on as well...Any advise or help is appreciated.
Thanks, Mitesh

hi mitster,
To access the CMOS battery, you need to remove the keyboard and the top cover. From there, just turn the motherboard over to remove the CMOS battery. (see page 54-57 of the hardware maintenance manual detailed instructions).
If reseating the CMOS battery doesn't give you a display, try to reseat the CPU. If still the same problem, the Intel HD graphics in the processor or the motherboard probably got damaged when the laptop fell into the floor. If you're near a local laptop repair facility, I recommend you take it there to test the motherboard / CPU.
Hope this helps.

Lenovo g560 keyboard stops working

All of a sudden my keyboard on my Lenovo g560 stops working then suddenly works again. Had this 2 months ago as well, was fixed by format and has been working since then. I really don't want to format again. I have updated BIOS and keyboard driver appears to be the latest version as well. Help?

Ok, a quick update. I unscrewed the screw next to the keyboard icon on the back and screwed it back. It worked for a while then stopped again. Started and stopped about 3 more times

Microsoft bootstrap manager has stopped working in my Lenovo G560!!!

I recently downgraded my Lenovo G560 to Windows 7 Ultimate from Windows 8 Pro (Werfault.exe error continued to reoccur even after clean installs). However, after reinstalling my drivers and programs, I cannot install any Office programs. I have tried installing Office 2013 and it encounters an error; Microsoft bootstrap manager has stopped working to be particular. I re-tried with Office 2010 and the installation fails to complete citing an error. These two office packages have previously worked in my G560. Used Office 2010 for a while before installing Office 2013 which I have used for two months. Does the recent install of Windows 7 Ultimate 64 bit have anything to do with it? How can I fix it? Any help will be appreciated.

I'll try that in a few days. I'm currently on the road. Didn't carry my external HDDs with me. Will try it then let you know.

Dc5850 cpu fan speeds to top speed sys then shutdown

I have a Hewlett-Packard HP Compaq dc5850 Micro tower PC, now running windows 7 pro 64-bit. That was new in late 2008. Originally it came with vista 32-bit downgrade able to XP pro 32 bit, running on 2G RAM, and 160G C drive with a 2.30 gigahertz AMD Phenom 8600B Triple-Core processor. It also has ATI 3100 integrated graphics as well as integrated NIC at 1G and integrated High def audio. In the first few months I had the system, I upgraded memory by 4G and total Disc space by 500G by adding a D drive; then upgraded to windows 7 pro 64-bit.
Overall, I have had a good experience with the PC but it has had problems while in its 3-year warranty. I did need to replace the C drive and later it original RAM devices. Yes HP did these replacements and swaps, under warranty; that meant I had 6G memory for a long time before the HP 2Gig failed out of warranty, leaving me with 4Gig now. Yes I have always had the Unit on an UPS; I even replaced the old UPS with a more powerful unit in late 2009 or early 2010 when the old UPS showed signs of failure. Now instead of serial based UPS connection it is USB.
Over the last few months I have been getting blue-screen errors of all sorts. Ranging from video related errors, Memory faults, Disc read/write failures and processor flag errors too. After numerous repair disc runs or re-install of windows, the disc read write errors wore corrected by the HP drive sanitation utility disc repair/wipe after failing the extended test. The non video ram was tested by a bootable CD of memtest86 v4 running extended test as well as MS memory Diagnostic. Both run multiple times, both passed multiple times. I was able to find a CD based video diagnostic for ATI and the Video passed repeated stress test as well. Over Labor Day I conducted these test and re-installed windows 64-bit; on the following Monday windows informed me I needed to activate windows, so I verified the correct key and called to do so, successfully.
With that background given here is the question. Recently over the last two or three months, for no apparent reason, mainly on boot the fan races to top speed and the system shuts down to protect itself. I researched this a little and found one cause to be inadequate airflow over the CPU to keep it cool; the recommendation made sense to vacuum with a computer vacuum and be sure airflow is not somehow obstructed. I am now thinking all these problems are related to the CPU temp sensor. Is it on the CPU fan or the motherboard, and can raising the fan speed in BIOS help prevent the problem, particularly if it on the motherboard.
John M Gray II

My pentium 4 3.0c stock Intel fan is 4.44 watts. Isn't the mobo designed for this?
Also, can the sys fan header have the speed sensor activated by a bios fix or is it a hardware issue where it just does not exist? If hardware, seems strange since Corecell shows sys fan.

The CPU fan starts with the case switch on and the system stops after 2 seconds

Hi,
I have just bought the MSI K8N Neo FSR (MS 7030) to build a new computer with (amongst others) an Athlon 64 3000 processor and an Enermax 3051 case.
The CPU fan starts when I switch on the power with the switch on the back of the case, but stops after two seconds. I don't get anything when I push the Start button of the case.
At the beginning I got some feeble orange light on the D-bracket LEDs. Now, there is nothing at all.
I have tried to do a CMOS and also to put the Mobo out of the case after having disconnected the HD, the DVD reader, the floppy disk reader and all the Front panel connectors ===> nothing changed.
The Power capacity of my case is 300 watts. I had computed on Power Supply Wattage Calculator (http://www.jscustompcs.com/power_supply/Power_Supply_Calculator.php?cmd=AMD) that it is quite sufficient for my system.
Other materials on my system: the MSI FX5200-T and a PQI RAM PC 3200 which worked well on a former MSI Mobo (K7N2 Delta). I don't intend to keep this RAM on my new system but I use it to test it, before installing the Corsair Value which are on the system with which I write this post.
Thank you in advance for your help.

Finally, it appears that I had damaged the motherboard and the CPU.
When I installed the CPU, I hesitated because the User's guide said that "the gold arrow should point towards the lever pivot", whereas the illustration and the AMD's one pointed towards the opposite corner. I had finally made the good choice (that of the illustrations), but I have certainly displaced some pins of the processor while hesitating.
The shopper told me that MSI will never agree that its text had troubled me and refused to give me a new motherboard.
I have finally bought an ASUS motherboard and, as I was fed up with the computer building, I paid a technician to do this job.
I would like to mention two other mistakes in the MSI K8N Neo User's guide:
- it devoted one page to the installation of the retention mechanism which was already installed.
- there was no explanation about the mention of two "Power LED" connectors.
I acknowledge that I have been stupid, since I should have asked the question of the direction of the golden arrow in a forum, where I would have found very quckly the right answer to my hesitation.
However, I am revolted that MSI does not acknowledge that a grave mistake and two troubling omissions in the User's Guide can lead novice people to grave failures.
I'll never more have confidence in a company that make such mistakes and does not assume its responsibility.
Once again, thank you for your help.

CPU fan speed = overheating. (Fixed)

Well, where to start.
For the past week I've been having problems with my system, turned out it was overheating because the CPU fan speed was very low, once I opened the Core Cell application it speeded up the fan and all is well (but I don't like having to run a bunch of applications to keep the system running the way it should be without. them and these applications don't start in safe mode.) I'm currently using BIOS version 3.30 and read "BIOS reported incorrect CPU temperature." but it does report the correct temperature, it is overheating because of the fan speed.
Does anyone know if updating to the current/latest version (3.60) will correct this problem with the CPU fan speed (it's only been hapenning after I updated to v3.30)
Motherboard: MSI 875P Neo-FISR
Thanks.
Edit: Fixed.

NovJoe,
That is a job by itself!
Everybody has different components on their systems. They buy cheap rams, case with insuficient power supply, lousy cooling, etc. and they are short on money like myself. How can I help them?? My general advise is buy top of the line components or buy a Dell if they don't want to research before they build a system. I know its hard to put out that much cash, I actually got my motherboard from a friend FREE! He had a lot of problems with it. I always had motherboards by Abit or SuperMicro Dual Processor and in the earlier years I had a Sun Microsystem SPARC 10 running Unix. I also get them FREE! They were prototypes before production lots of jumper wires. When I retired at age 47, five years ago I only work part time now when I need spending money like for Christmas and 10 different hobbies that my wife thinks is to much. Yes I wrote CHRISTMAS not Holiday. Grandkids, my wife spoil them all year, but we have to get in the spirit of Christmas she said. AHH HUMBUG! LOL! I need a couple of those new 300 GB SATA Maxtor drives with Command Queuing to get rid of my four 20 GB Maxtor and one 40 GB, I also got them free when I did a job for them 8 years ago and they are still working great. It will reduce my +12V load, increase my storage capacity and my hard disk speed. I had them on a Promise 66 PCI RAID controller card on my old SuperMicro Dual Processor motherboard.
If a person has a problem with a MSI 875P NEO-FIS2R and a decent setup, I will definetly give them advise if I can.

CPU fan plug stopped working

I started my rig the other day (actually about 3 weeks ago) and the cpu fan was not moving. Tried a few things but finally stuck the cpu fan plug into the sys1 fan slot and its now working. Will this be a problem in the future or will the mobo be fine without the cpu fan plug not working?
Everything else seems to be working fine - any suggestions on what to do?

I see no problem on not having your cpu fan plugged directly into the cpu header... but it may just be a tempory fix for an underlying problem. Any stability issues? Also if that header dies you can always plug directly into the power supply 4 pin to 3 pin cables are not hard to come by.
Good Luck

CPU Fan - constantly runs at high speed

Just like the title says, my CPU fan is constantly at a high speed. It's loud and I haven't been able to figure out how to set it back to normal. It's a Dell Optiplex GX620. I swapped the power supply, re-imaged the hard drive, and flashed the BIOS to the latest version from dell's website. I looked through all the BIOS settings and logs and didn't find anything. I've asked every IT I know, and gone through a million forums with no real explainations or ideas to this issue. So far the best advice I've got is to turn it off. My theory is if I find the driver that controls the CPU fan and update it, the system won't see the CPU as overheating and it will return to normal. I'm close to just replacing the motherboard but thought I'd post something first. Anybody have an answer?

Go to www.AMD.com or
www.VGA.com and post your problem in the forum that best fits your problem or start a post of your own. Be a lot more detailed then you are here about all the equipment it will be very important when trying to diagnose. Do not throw out your mother
board and stop replacing parts your waisting loot. when you go into the the AMD web site and post under the proper forum You are going to hopefully run into one of three people Gr33nGecko, SteveO_Crossfire or Black Zion these three people
are experts in there field and have forgotten more than most people know. If stevo responds to you he will have a website posted in blue near the bottom of his post or ask him to show you his system you might want to be sitting when you see the unit
for his house. I could run a good size town on the darn thing and wait to you see the cooling tower on top. Iv'e seen smaller units on power plants lol. Just joking but the darn cooling tower is still huge . I know Gr33 is in several forums as a
supermoderator and has over 17,000 post listed that I am aware of. Well good luck and dont give up.
I know of several reasons your unit maybe overheating but I think you would be better off with anyone of these three techs. and it would be good if you had a second computer/laptop near you. When I am working with them I use a lap top that way I can
do voltage checks or whatever and I am responding with questions and answers without delay and I am not blowing up my computer or myself to answer or check a problem that would normally require me to shut down my problem computer and still be able to
talk with the guys.
Good luck

Error In Installing Windows XP in Lenovo G560

Hi,
I am using lenovo G560 with Windows 7. Now i don't want to use it any more. so i decide to install Windows XP like normally in Desktops as i had used desktops only.
Boot from CD and windows Set started with loading files....in middle it stops by showing Blue Screen of Death I am not sure about it why is come.
Please suggest how to install Windows XP to replace windows 7 in lenovo G560
Solved!
Go to Solution.

Hello everyone!
I am using Lenovo G460, i guess it is not that different from G560 for the purposes of this discussion.
I had the same problem with a blue screen. I changed settings in BIOS from AHCI to Compatible and installed XP. After that I updated BIOS from within the XP, installed all the drivers, including the AHCI driver from Lenovo website.
Then, I go back to BIOS and change settings from Compatible to AHCI, and I get the blue screen again.
Ok, i don't know anything about NCQ and hot swapping, which I read about on wikipedia, and which i suppose are supported by AHCI, but my question is:
Should i now always stay with my settings as Compatible in BIOS and, therefore, never be able to use such features as NCQ and hot swapping? I repeat, that I don't know anything about AHCI or Compatible mode, but I figure that AHCI is better.
Please help me in finding the answer, whether to stay on Compatible and forget about AHCI, or may be there is some way to solve the problem for XP users with AHCI mode.
Thank you very much.

Fan issues -- computer overheating?

I have a quick question. I have an iMac G5, (non iSight version). My computer has an overheating problem -- the fans will run at high speed 99% of the time and when running a large application (such as a large game like World of Warcraft, and occasionally when even doing something like watching a baseball game online) the computer puts itself to sleep to, I believe, avoid overheating. I've done some research and I think this is not an uncommon problem. I was wondering if this is something I can fix on my own by ordering parts from the DIY section, or if I have to bring it to an apple store? If I can do it, what parts would I need? Just the fan? Thanks for any help you can give me!

Hi--
the computer puts itself to sleep to, I
believe, avoid overheating.
You can verify this by using the Console application from your Utilities folder. Open it up and look at the log and see if you see messages like this:

The Apple Store's solution was a new logic board. Mine's a Rev. A, though, and covered by the repair extension program, as well as AppleCare, so I had no problem with them. The CPU fan for some reason was unable to cool the CPU, despite the fact that it rand at nearly 100% speed constantly.
Some people have reported that they have found the vents along the bottom of the computer have gotten clogged with pet hair or dust and that cleaning them out helped slow the fans and cool the computer. So you could look into that. Also, you might take a look at where the computer is sitting and see if something has changed that is forcing the warm air vented at the top back into the case at the bottom.
If none of those work, though, you might need to have it looked at. Whether or not the fans can be replace indivually on your iMac, though, I'm not sure. You'd need to talk to Apple to find out...

CPU Fan running fast

Hey Guys!
I've some Problems with my IMAC 27" early 2011.
The CPU fan is running at about 3800 RPM even though, the sensors say, the CPU is pretty cold.
Here the Temps that iStat gives me:
HD: 41° C
CPU: 33° C
GPU: 43° C
MEM: 38° C
Optical: 38° C
CPU Usage: User 0-2 %, System 0%, Nice 0%, Idle: 98-100%
The problem occours some 10-15 minutes after I've switched on the IMAC and it stays, even if I restart the IMAC for at least 2 hours. Once the fan is returning to it's normal RPM (after 2 hours or more, mostly after being in Standby), i can work for several days and it doesn't return, unless the IMAC is switched off and on again. I think, the IMAC slows down, when it has this problem. Especially scrolling in Safari is extremely slow then. Sometimes it even stops!
Things I tried to correct this:
SMC-Reset --> Didn't succeed.
Start in 'Safe Mode' --> Well it's running in save mode right now and sounds like a vacuum-cleaner.
Disconnect all externals --> Nothing
Deactivate Time-Machine --> Nothing
P-Ram-Reset (?) --> Nothing
New User Account --> Nothing
I think the problem first started to be there some days after installing Lion. By the way: My MBP 15" Late 2008 runs great with the same stuff on it.
Anybody got any ideas?
Thanks a lot & greetings from Germany!!!

I've got the opposite problem, my AMD CPU is running around 55C and the fan hardly ever exceeds 1200 rpm most of the time its running around 950rpm. I think the 48C to 65C is running on the edge of to hot in my opinion, I like to stay around 35C-40C. Motherboard, video card and hard drive all stay in the 30C range. I tried to speed the fan up with SpeedFan program but it can not interface.
I hope someone can give us a answer, I checked the UEFI and could not find any setting allowing controlling fan speeds on my ENVY 700-200z/AMD A10 cpu.
