[SOLVED]thinkpad edge e420 fan problem

Hello I own a Thinkpad Edge E420 1141-GJG laptop.
The fan runs at a constant speed sometimes overheating the laptop.
I want the fan speed control to be done automatically so I followed the the steps presented here to no avail.

Edit /etc/sensors.d/sensors.conf and look up your exact chipset. A few chipset names are similar, so make sure the one you are editing is yours. Add the line 'set fanX_div 4' near the start of your chipset config, replacing X with the number of CPU fans your system has.
How can one find the exact chipset name? The overall information spilled out by dmidecode is staggering.
Later Edit:
Accoding to http://en.gentoo-wiki.com/wiki/Lm_sensors#Configuration ,the chipset name should be in the sensors output.

Thinkpad Edge E420 does not boot up and customer service does not help

I have a Lenovo Thinkpad Edge E420 laptop that stopped powering on all of a sudden. It was working fine till one day fine and all of a sudden, does not boot up the next morning. I have googled around and looked in Lenovo Forums and it looks like this is a common issue with motherboard on these types of laptops and that lenovo fixed some of these. Unfortunately, my laptop is out of warranty but I do see that Lenovo fixed similar problems for some laptops that are out of warranty. Please see the two threads below
https://forums.lenovo.com/t5/ThinkPad-Edge-S-series/thinkpad-e420-wont-start/td-p/755813
https://forums.lenovo.com/t5/ThinkPad-Edge-S-series/E420-motherboard-problems/td-p/667009/page/10
So, I tried calling customer service multiple times hoping that I could get to talk to a supervisor and explain the problem. Just today, I was told I need to agree to pay $575 (which is much more than what the laptop is worth) to even talk to a supervisor. This is quite disappointing.
If any Lenovo support staff is monitoring it, can you help here?

Its not the motherboard even though they say it is. All they will do is replace the motherboard and it will just fail on you again. I had the exact same issue and the motherboard was replaced. Next day I used it it failed again. You need to remove the CMOS battery which is located underneath the laptop. Its in the compartment with the one screw. Remove that. Remove the battery and all power supply. Then plug the CMOS back in and plug in powercord. Once you have done that start up as normal. Press f1 to enter BIOS. Go to the Config tab and under "power options" disable "rapid intel start." That worked for me as a temporary solution.
It clearly isnt a motherboard fault as all Tech support from Lenovo claim it to be. I mean c'mon I had the exact same fault the day after my motherboard was replaced, but after removing CMOS and battery the motherboard magically starts to work?? Must be related to the W5 problem they have been having with BIOS.
Heres a link to another thread with others with the same problem.
http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/E540-power-issue/td-p/1326979/page/9
Let me know if this helps at all since no one from Lenovo seems to care about helping their own customers... very dissappointed with the customer service. Personally I dont think Ill ever purchase a lenovo product again after their pathetic execuse for "tech support." Anyway good luck!

[Solved]Thinkpad T410: Annoying button problems

On my Thinkpad T410, the light on my keyboard speaker mute button won't turn on, and the light on my mic mute button won't turn off. I have no idea what to do. Any ideas?
EDIT: Upon further investigation, I have also realized that my microphone is stuck on mute
Another Edit: I'm not qiute sure why, but adding acpi_osi=Linux as a kernel parameter, rebooting, removing it, then rebooting again fixed it.

Thinkpad Edge 420 HDD to SSD

Recently, my HDD has begun to grind to a halt on my Thinkpad Edge e420. I decided to replace the HDD to an SSD, and after many, many unsuccessful attempts to reinstall the OS via Rescue and Recovery, cloning the drive etc, I decided to install the OS onto the new SSD using a windows disk. While this seems to have worked, I now no longer have any of the preinstalled Lenovo software. This is disappointing, but also seems to have reduced the functionality of the laptop (eg the networking device is no longer recognised).
Could anyone please recommend a method of reinstalling the Lenovo software onto this new SSD.

Windows 7 right? Download ThinkVantage System Update, it should download most of the drivers and applicable softwares for your E420.

Thinkpad Edge E440 Random Lags, Stuttering, Latency Problem.

Dear All, I bought Thinkpad Edge E440 almost two weeks ago. The problem is it randomly lags and stutter without reason. For example I was writing documents on Microsoft Word, plays music on foobar2000 and doing some light browsing (only few tabs) but randomly the music lags for 1-2 seconds. It doesn't skip, it lags or stutter (sorry I don't know the right term). Also sometime it took awhile to open a new tab on firefox web browser while usually it took instantly.
Another example is I play two online games, World of Tanks (WoT in short, a tank simulation game) and Ghost Recon Phantoms (a shooting game). When I play both game, the gameplay went smooth but randomly it lags or stutter like 1 second on more, then it went smooth again and then stutter again. The game doesn't became slow (which is called FPS drop if I am not wrong), the display just stop moving and mouse/keyboard become unresponsive during the lag/stutter period. On the other hand I also played WoT on my Pentium 4 PC and it went smooth without any lags, though of course the settings is inferior to my E440 laptop (Ghost Recon Phantoms can't be played on my Pentium 4 so I won't compare it).
Also sometimes the audio sounds 'spiky'.
As I searched online, people said that this is called/related to Latency problem and I should use LatencyMon to check it. After using LatencyMon I found several 'culprits' which causes big latency such as NDIS.sys, ACPI.sys, ATAPORT.sys, storport.sys, etc. I also tried to disable cpu throttling, power management settings and such but the problem doesn't go away.
I am sure that there is something wrong with my hardware because if its caused by settings such as cpu throttling, power management (which I think is software-related) then won't this happen to everybody? I mean, I asked a fellow E440 user and he said that his laptop is fine and my problems doesn't occur on him.
I have phoned Lenovo Customer Service. I was using Windows 7 Ultimate. At first they told me to do clean reinstall and install the drivers in the order the CS give me. I did clean reinstall 4 times to try different driver and program installation sequence to see if I might find a way to fix my problem, but I found no solution (I tried Lenovo CS driver install order on the last clean reinstall). I even tried running LatencyMon after clean reinstall before installing any drivers or updates but the LatencyMon still reports big, 'unhealthy' latency.
Lenovo CS then told me to do hardware scan on Lenovo Solution Center. There are warning on the Nvidia GT740M stress test but the CS told me that the results are good. His last solution is that I should go to a Lenovo Service Center to check for the problem there.
I moved to Windows 8.1 to see if the problem will be solved but too bad it's not. I have ran hardware scan for 5 times, there are two times(or 3 times I forgot) that there is warning on Harddisk SMART short self-test, 2 times warning on Nvidia GT740M stress test, one time scan finished with no warning. Even so, the end result for all the tests is 'Passed'.
I think the problem lies within my harddisk (or something related to data transfer) since when I browse my local drive in windows explorer sometimes it took a long time for the icons to load but sometime it just loads instantly. And I am not sure what that Nvidia stress test warning has to do with.
Also I only use the stock 4GB Ram. Could this related to the problem? Though when I look at Windows 8.1 Task Manager the memory usage rarely goes above 60%.
Last but not least. I plug a wireless mouse on my laptop which I use mostly for playing games, but in the end I switches between mouse-touchpad-mouse and so on during working too. Sometime my touchpad suddenly went unresponsive for few seconds but my mouse is still usable during that moment. Then after I move my wireless mouse, my touchpad become responsive again. Any idea why this is happening? I think this is probably because touchpad driver not perfectly compatible with Windows 8.1 as I don't recall having this trackpad issue on WIndows 7.
Can somebody help me? Does anyone else ever had the same problem as I do?
I am sorry for the really long explanation. Your response will be greatly appreciated.
Thank you.
-Tahta

Hi All, sorry for being a while for a long time.
First of all, I should say that I am not sure if my trackpad/pointing device problem is related to the lag/stutter/latency problem so I should have made two different thread instead. Sorry if anyone got confused with this.
@rallygion, the first OS I used on this laptop was Windows 7 64bit. If I remember correctly I don't experience the trackpad/pointing device problem back then, maybe I was just forgotten tho. I am using Windows 8.1 starting sometime before I made this thread. Now the problem has gone worse, sometime the touchpad & red dot in the keyboard won't work for a whole day so I must use external mouse.
At first I thought its compability problem with Windows 8.1 but now I think the hardware has problem too. However, the keyboard is fully functional.
@waqs, thanks for your suggestion! Unfortunately it doesn't solve the lag/stutter/latency problem.
@ghasan, our problem is quite similar except I didn't use the M.2 SSD. One thing I notice is the disk activity sometimes jumps to 100% when the lags happened.
The problem doesn't lie with the laptop specification is inferior. Fyi, when I play music on foobar2000 it took few second for music to start playing (foobar says 'starting playback..') while on my pentium 4 desktop (which I still use) the music plays right after I clicked the song.
Also, eventhough I've closed all my applications, leaving only music player and microsoft word/firefox, the music which is playing lags (randomly stops for a moment).
The lags also happened when watching videos. I played video on Media Player Classic, turned the statistics on. There happen to be frame drops sometimes. Not framerate drop, just frame dropped. I mean, I think framerate dropping has relation with computer power while in my case the frame just randomly drops, which 'damages' the video, not slowing it down.
I am sure that this is hardware-related problem. I am going to take my laptop to service center but not now since I am in need on my laptop now.
I will give update later when I have gone to the service center.

Does Thinkpad Edge E545 have a non-stopping fan?

I was thinking of purchasing this model:
http://shop.lenovo.com/ae/en/laptops/thinkpad/edge-series/e545/
I don't need anything fancy just something reliable so this would suit me fine. I mentioned it to a friend who said he bought the E530 and has regretted it ever since due to an issue with the fan. Apparently once the fan starts it doesn't stop. There is a 90-page thread about here:
http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/E530-pulsing-whiny-fan-no-low-load/td-p/797577/pa...
I had assumed this would have just been an isolated model problem. What is concerning is that not only have Lenovo not fixed the issue but I have come across similar complaints about the next model, the E540:
http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/E540-Fan-does-not-stop/td-p/1439657
If the same issue is present in the next model am I wrong to assume it is also present in the E545? Can someone confirm either way plz. I am also considering a Dell Latitude which I will purchase if there is no confirmation the problem has been addressed, but I would prefer to get this model.
Regards, Miranda.

I set up an account just to reply to you!...and also I just bought a Lenovo Thinkpad Edge E545, and I want everyone to know what they're doing. Plus, I'm having the same problem. I just downloaded the Broadcom Wireless LAN (Driver here! Remember to choose for either Windows XP, 8, 8.1, or whatever you have!) and I've seen past comments that this has worked for them. I'm about to go try it out, so wish me luck! I hope you haven't returned that laptop you bought! Lenovo is usually such a good brand, from what I hear, and I personally already enjoy the exterior, as I put structure, stability, and damage-resistant against style, which the Edge E545 seems to be more for the accident prone or careful type, but still cool! Good luck!

[SOLVED] UEFI shell won't work on Thinkpad Edge E520

Hi there,
I have installed the x86_64 UEFI Shell 2.0 on my Thinkpad Edge E520 which is already booting in UEFI mode using refind-efi for some time now. The same shell is running just fine on my desktop system.
But - on the Thinkpad it doesn't run. The shell is installed as /boot/efi/shellx64.efi and when I start the laptop, refind appears and shows me the shell icon (amoung others). But when I choose the shell from refind I get a black screen with this writing:
Starting shellx64.efi
Using load options ' '
ASSERT_EFI_ERROR (Status = Device Error)
ASSERT c:\dev\edk2tip\Build\Shell\RELEASE_VS2005\X64\ShellPkg\Application\Shell\Shell\DEBUG\AutoGen.c (431): !EFI_ERROR (Status)_
I don't know if the text is going on after the last underline. If yes I cannot see it because the text is running out of the screen.
The funny thing is - exactly the same setup is working pretty nice on my Asrock ITX board but not on the Lenovo Thinkpad Edge E520.
Any ideas? Just say, if you need further information.

Okay, found the - somewhat obvious - solution myself. The UEFI Bios on my Thinkpad is an "old" UEFI 2.0. So, Shell 2.0 won't work on this system (as I could have read in the wiki ).
Now, I have installed Shell 1.0 and I can enter the shell from refind .

Lenovo Thinkpad edge 15 - Problem driver VGA controller with Windows XP

Hello,
I downgrade my thinkpad edge 15 from windows 7 to XP. I found all drivers on the site except the driver of VGA Controller. Where can I found it ?
Computer configuration :
ThinkPad Edge 15 (0302-47G)
Windows XP Service Pack 3
Athlon P540(2.4GHz) 2GB RAM 500GB 5400rpm HD 15.6in 1366x768 LCD ATI Radeon HD3400 CDRW/DVDRW 802.11bgn wireless Bluetooth 1Gb Ethernet UltraNav Camera 6c Li-Ion Win7 Pro 64
Thank

What do you mean it "refuses to work using bluetooth"?
The iPhone does not support bluetooth file transfer. The only thing you can use it for with any computer is tethering the internet connection from the phone. You can not sync or transfer data with your computer via bluetooth. You can sync via cable or WiFi.

Thinkpad Edge 15 TVSU "Not applicable" after fresh wipe of Windows 8.1 and install of Windows 7

Hello,
I have a user that purchased a Lenovo laptop and is having problems downloading drivers to support the machine now that it has Windows 7 (via Volume Licensing) on it. When running System Update after Windows updates, it will tell me that "There are no drivers that are applicable" when I know for a fact that he does not have touchpad software or the ability to light up his keyboard. When trying to install the Synaptics UltraNav Touchpad Driver it will tell me that a touchpad doesn't exist.
Any help would be great,
-Bobstod

Good day and welcome to the community.
Please confirm whether the machine in question is one of this type (model code number may be slightly different):
http://shop.lenovo.com/us/en/laptops/lenovo/flex-series/edge-15/index.html
If so, then we can move your thread to the 'non-ThinkPad' Edge subforum.
Also, if it's one of this family, then applicable drivers can be found here:
http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-edge-series-laptops/edge-15-lap...
Please do let us know.

Black screen after suspend on a Lenovo Thinkpad Edge E525

Hi everyone!
I own a Lenovo Thinkpad Edge E525 which is running Arch. After waking up my laptop from suspend mode, the screen stays black and the laptop doesn't seem to respond to any input (even the SysReq keys don't seem to be working
I followed the instructions from the wiki (especially the laptop specific page and the pm-utils page), but it still doesn't work.
I'd be happy to provide more information if necessary.
Many thanks in advance,
ElVirolo.

Any other insights?
I'm having this same problem on my Thinkpad T60. Both suspend-to- disk and -to-ram result in a system which does not respond. The crescent moon led indicator stays lit after resume. At first there's some disk activity and then nothing.
My system worked fine about a week ago, but after upgrading (to kernel 3.3.2-1 among other things), I haven't been able to suspend properly anymore. I have tried all sorts of fixes in the wikis and around the net, but nothing at all seems to help.
Has anybody else had suspend/resume problems after recent upgrades?
Edit: Also, after trying to resume, I can hear the fan beginning to rotate. Though the laptop seems to be unable to wake up, the fan is active. I also assume the CPU is under a heavy load as the laptop gets quite hot on on the left side.
Edit: Downgrading kernel does not help.
Edit 2:
Ok, this is weird.
I normally don't have the module (snd-hda-intel) for my sound card loaded. As soon as I load it manually, at least suspend begins to work normally. Why is this?
Is there a way to tell the kernel not to touch the module when resuming from suspend? I have the module blacklisted.

Lenovo Solution Center Windows 10 On Thinkpad Edge 15

Just upgraded to Windows 10. Ran Windows Update from Control Panel a couple of times. However, the Lenovo Solutions Center alerts showing Windows Upgrade never done. When I click on "launch" or "Windows Update" nothing happens. The is on a Thinkpad Edge 15. I was hoping to find a download for the Lenovo Solution Center software thinking I could delete it and then download it and reinstall to solve the problem. Obviously if there is another way that would be nice to know.

I have same problem on a diiferent model Lenovo desktop PC. If you want to try reinstalling the solution centre software, you can find it here: https://support.lenovo.com/us/en/lenovodiagnosticsolutions/tools/lscoverview Let me know how this goes, I might also try this myself.
