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.

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.

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 13" sudden BATTERY problem

Hi, i am starting to be desperate, therefore i registered myself here. Let me explain my story.
My computer is now almost 2 years old and I have less than 14 days till the warranty expires (I am from Europe), but I'd like to avaid this, because i really need my computer now, not after 30 days, which is by law designated time till which it must be returned to me back. I did not have to use my computer outside home for about 3 month, so I was using that during that period as desktop computer, where i set in lenovo power manager, that all energy should be taken from the AC adaptor letting the battery to deplete itself in its own pace. But i have taken my computer to the libraries lately and i have experienced sudden battery problems. Let me describe them in order as it happened.
1) battery shows that that it has more than lets say 20% of power, but windows power manager warns me that battery capacity is in reality 6% and i need to use my AC adaptor now. after second even lenovo power manager recognize the fact that battery is almost depleted. first i did not pay attention, i thought it was some temporary bug and it will not be repeated again.
2) unfortunatelly it was, therefore i updated lenovo power manager to current version (6.11), which realized that current battery capacity was not 54Wh (as before update), but 47Wh. Therefore I resetted battery gauge statting that battery capacity is now slightly over 51Wh. For couple of days everything was as it should (probably, because i always connected AC adaptor around 10% of remaining battery).
3) now my problem appeared again, though battery depleted naturally and slowly to 10%, after that windows power manager popped again showing, that battery is 6% and I need to use my AC adaptor. after connecting to electricity whole W7 froze for a while. I rather restarted system after which I realized, that battery info is wrong again - original capacity of battery since i have this laptop was over 62Wh, now is slightly over 57Wh (this is something new i have not realized this 2 days ago, when i was doing the reset, and I'd bet i happened just now) and current battery capacity rose back to 54Wh (as I said before, after the last reset it was just 51Wh).
I attemted to do Battery test through Toolbox, but system refuse to run this test (even after resterting system) stating "Cannot run".
For a while i thought i have this problem which requires updating battery firmware: http://support.lenovo.com/en_US/diagnose-and-fix/detail.page?DocID=HT003431
but FRU number of my laptop is 42T4813 and is not in the list of batteries requireing update.
Sorry for long text, and quality of English (I am not native speaker), any help is welcome. Thank you in advance.
PS: i always install updates throught System update, my BIOS should be therefore up to date, i also Lenovo Power manager does not offer any update for battery firmware.

After todays restart original baterry capacity is restored back to 62+Wh, But current capacity is still 54Wh, higher than after last battery reset. I am upgrading to higher version of Power Manager.

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 E455 Excessive Battery Drains When Power Off

I bought a new ThinkPad E455 two months ago with AMD processor and I use Windows 7 (64-bit) as my operating system. The problem is, since a week ago, when I turn off my laptop (completely shut-down, not hibernating nor sleeping), the battery looses 14% in less than 24 hours. This problem has never happened before. When I search for solution, apparently my problem is similar to https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E535-High-battery-drain-when-laptop-is-powered-off/ta-p/1249897 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E530-Battery-drains-and-power-manager-issue/ta-p/1249887 and https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/E440-battery-drains-when-powered-off/m-p/1527086/highlight/true#M18743. It appears that the power drains happened in other type of ThinkPad as well. Moreover, it seems that this problem is not limited to ThinkPad series (e.g: http://www.tomsguide.com/answers/id-2324931/laptop-battery-drains-powered-shutdown.html), and more surprisingly, some of other brands experience this condition as well. My question is, what causes the power drain? I mean, the laptop just worked fine for a period of time (in my case it is two months), if it was trigerred by something, what is it? I looked for the technical updating BIOS solution in http://support.lenovo.com/us/en/documents/ht077068, but unfortunately the series E455 is not in the list. Of course, updating the BIOS using incompatible version is not recommended by the technical support. Please help me.

See https://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface When you think the laptop is powered off it's actually in ACPI Power State S5 with power being supplied to the power button and some of the USB sockets. So, when you shut down the laptop and then removed the power cord, if the BIOS version was lower than 1.13, the laptop was still draining the battery.I followed your suggestion, and it seems solving the problem, thank you. However, another problem arises just recently. When I was playing a game on my laptop, the battery capacity is decreasing when the AC power connected (as described by both lenovo and Windows battery gauge). I post this problem in https://forums.lenovo.com/t5/11e-Windows-E-and-Edge-series/ThinkPad-E455-Battery-Capacity-Reduced-When-Connected-to-AC/td-p/2106218. Oddly, the problem (seems) does not occur when I quit the game to windows. Why was this happen?

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!

My Thinkpad edge e330 gets very hot with xubuntu 12.10

Hi,
I own a Thinkpad edge e330. IT is perfect for my use. And I love it alot. but it has some problem. it gets very hot with xubuntu 12.10.
the temperatur goes up to 70 after using it in 30 min. even when it is not hot in the room. I think it is very strange and 70 is very high for a Intel computer.
Can anybody here tell me how to make the temperatur come down? thanks!

For sure that isn't normal temperature. I have E330, i3-3110M, Ubuntu 12.10/13.04: temps stay around 40-45 celcius in idle/low load.
- what about the temperatures on Windows? If they're high too, I'd really suggest some vent dusting too...
- what BIOS settings do you mean?
Check that the CPU frequency scaling is working (wouldn't expect the problem to be about this though, but you never know...):
cat /proc/cpuinfo | grep -i "cpu mhz"
TLP power management might also fix this issue, but regardless of the issue I recommend to install it (easy to install via PPA): http://www.webupd8.org/2013/04/improve-power-usage-battery-life-in.html
I'd also try updating to Xubuntu 13.04... there is always something new and this could be a bug.

Thinkpad Edge e430 Not Powering Up.

My laptop thinkpad Edge e430 is not powering up. When I plug in the AC cord the LED indicator does not turn on. I have checked the AC adapter with the multimeter and it gives 20 volt output. So the AC adapter is fine.
The laptop also does not power on with a fully charged batter. I have removed the HDD, Memory, Optical drive and the CMOS battery and then pressed the power button for 30 seconds. The laptop does not wake up.
It is quite weird as the laptop should show some kind of error So i may have an idea what is happening.
Discussing with people on other forums gives me an idea that the power setup of the laptop is faulty. Can some body here guide me to what the problem is and how can i fix it?

Hello everyone,
THIS IS MY EXPERIENCE SPILLING WATER ON MY T400.
I happened to spill water on purpose on my Thinkpad T400.
I am quite young though I just removed the four of the ram screws And also removed a keyboard screw as well.
Then, I opened the lid cover and then I removed the touchpad . Then , I also removed the keyboard . I saw that water had entered the cooling fan and I also found some water near the Intel Core 2 Duo Processor .I also found water near the hard drive and beneath the speaker guard, So I removed the silver panel from the interior of the laptop.I also removed the CD drive. I let it to dry under a FAN ( I did not use a hair dryer because it may damage the components.Then I put everything back it 3 minutes.i turned it on .it did not even power on, instead I heard 1 beep,3 beeps,3 beeps,1 beep. I surfed the internet and found that the error means that RAM is not proper or there is some issue.I again refitted the RAM the way it was before( I changed the arrangement before which caused this error).
Then, to my surprise I saw Thinkpad on the screen and the Windows XP Operating System began to load!
I checked whether I had connected the keyboard and mouse properly.Everything was fine.
I LOVE MY THINKPAD.
You may use this method, BUT please be extremely careful that you do not possess static electricity.

Chris

Reception / Battery problems with iPhone 3GS after upgrading to iOS 4.2.1

There are major reception and battery problems with iPhone 3GS after upgrading to iOS 4.2.1.
I can not believe that Apple did not test this for major bugs like this one is.
I am a business user and can not effort to have bad reception. Apple wants to gain in the business clients... I never had this with my former BlackBerrys!
I need a reliable phone not a play thing like this is right now, it just needs it to work propely. And if a major bug like this comes along, fix it immediately. After the iPhone4 story, now this...incredible! Going back to my reliable BlackBerry! It just ain't reliable and takes forever to fix a problem.

I have the same issue after iOS 4.2.1 update. I am using iPhone 3GS officially unlocked by Apple. I tried using different SIM cards and both carriers show same problem when using phone in 3G mode. Phone falls back to EDGE mode showing 'E' from '3G' at start. I have reset the phone and rebooted several times and moved to different cell areas in the city just to verify the problem.
I had no such issues earlier. I also have Nokia E71 which shows full signal and has no such issues.
I have posted the bug on apple iphone feedback page. I hope they Apple will fix the problem and test the release properly on all models before releasing to public.

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:

Please do let us know.
