Lenovo ThinkPad L R/SL :: L420 / Windows 8 64bit - Audio Playback Jitter / Distortion On Battery Or Charging
Jan 11, 2013
So this is about the only issue I have with Windows8 on my laptop, I've tried various audio drivers from OEM provided
to drivers directly from the Realtek site and I can't seem to remedy the issue....
Only during charging of my laptop or when the laptop is on battery does the jittery/distorted audio playback occur. Happens during Flash playback or local media playback using say VLC, sometimes the distortion can Freeze or lock up the system.....
I've tried Audio Drivers, Video and my BIOS is the latest. This playback issue did not occur under Windows7 when I had it installed....
I am using Lenovo ThinkPad-L420 Model. While I walking, I would like to play some mp3 files(playing songs/music) and hear (via ear phone) using my laptop. What happen is when I stop walking laptop is start playing the music, If I start walking again laptop is stop playing.
I have installed the latest driers and since then I am unable to change the screen brightness using function keys. I have installed multiple driver updates hence it is difficult to find out which driver is causing the issue.
With this laptop, the CPU usage rises significantly whenever the battery is charging. If I'm on running on battery power or it's fully charged, I don't have this problem. The CPU stays at 2-3% while browsing the internet, for example. But browsing the internet while the battery is charging will send the CPU up to 90-100%. It's not just browsing the internet, but any task, such as running Sony Vegas, using Skype, watching a movie, etc.
Again, this only happens while the battery is charging. Everything runs much, much slower. All power management settings are identical whether it be running on battery or charging with the AC adapter, so it's not that. I am also using the 65w power adapter that was supplied with the computer, and the adapter becomes very hot to the touch while charging.
Can i disable battery charging on thinkpad x201, so i don't need to pull out my battery every time? Because although my battery stop charging when it is fully charged i don't want to use battery as power sourse after that.
I have a problem with my Lenovo ThinkPad X300 computer. The battery charging stuck at 99% (remaining capacity about 69% and 300 cycles). The Power Manager displays, the battery is at 100% but "status" periodically changes - both Power Manager and Windows battery indicator - between "No activity" and "Charging".
Every time stuck at the same "Remaining capacity". As i noticed during battery user windows and the Power Manager displays different information about the remaining battery level and time.
I use a T440 with WIN8.1 pro machine but for whatever reason the external battery has stopped charging. As this laptop is only 3 months old Lenovo send me a brand new one but the outcome was the same, the charge symbol comes up on my screen when rebooting the machine and shortly after stops completely. I have now had my internal battery pack changed and again no improvement.
I bought a T510 few days ago and was surprised to see this machine has ridiculously low volume. I have tried everything including the tweaks in Smart audio and removing audio limiter but still the volume is very low. On my dell 1525, I never go past 40% volume on my headphones but on T51o, I am using 90-100% volume to watch videos on live streaming websites.
Is there any solution to boost the volume on T510? My system is with windows 7 ultimate (64-bit) and audio device is Conexant 20585.
I have a brand new W540 with Windows 8.1 running. Some Fn-Keys are working, for example Fn+F2 for the volume. But I have some keys which are not working: Fn+F5 or Fn+F6 should change the LCD brightness.
Why these keys are not working? All updates are applied (Lenovo and Windows)...
After i installed windows 8.1 64 bit on my device, the audio beats control doesn't appear and i don't know if it's working properly or not, and i don't know if it's built in the original speakers.
My Device: HP Pavillion 15-p150ne OS: Windows 8.1 64 bit
Today i installed window-8 Pro (64 bit) in my thinkpad E430 machine, but after installation its not charging, its showing PLUGGED IN , NOT CHARGING , its not charging beyond 33%.
I use a T440 with Windows 8. External battery not charging. Always 0%. The internal battery is charged to 80%, external battery will not charge. If I disconnect the external battery, the internal charging to 100%. Did fully discharge, it is still only charged internal battery.
We have bought many L430 notebooks and with Windows 7 the audio output is very low... we have tried with both realtek and windows HD drivers but the result is poor out put...
I have this strange audio issue, that started when I upgraded to Windows 7.
When my speaker configuration is set to Built-in Speakers, I will intermitently get a hard buzzing distorted noise coming from my right speaker. It mostly occurs when I'm doing something, (browseing the net, navigating through explorer etc). Its stops on its own eventually, but sometimes can last a long time.
Heres what I know so far. -The strange thing is that there is no distortion with headphones, its only the built in speaker.
-The problem is intermitent and does not occur in 5.1 mode, so its not a physical problem with the speaker, it must be software/driver related.
-I have the latest RealTek Drivers from Acer.
-The problem does not occur when my speaker configuration is set to 5.1 output.
When I pause playback of an .mp3, there's permanent white noise coming from the internal speakers.
Stopping the playback stops the white noise after approximately 4 seconds. I never had this issue with any laptop / soundcard. Can this be fixed?
I have the latest BIOS and drivers installed. Headphones are fine (no white noise).
Maybe the inbuilt L440 soundcard has a problem. I had to return my first L440 because there was a loud plop when starting playback and the left speaker was way quieter than the right one.
In the German part of this forum people are reporting problems realted to the internal speaker (cracking sound, white noise).
I have recently purchased a new i5 vaio S from bestbuy. the first one that I got had a squeaky keyboard so I returned it for another. Both of these brand new computers audio randomly glitch out after about 20ish minutes of listening to music. This happens with both headphones and using the laptop speakers. I can only describe the sound as if you tazer'd a robot... its the weridest noise I have heard and only last for a second and then music continues to play. This happens with music on my computer, youtube videos, ect...
Lately I've been having issues with the sound, which I believe to be temperature related and I wasn't sure whether to put this in the audio or hardware board.
Anyway, at least once a day I have to restart because any sound output-- videos, skype calls, music-- beging to stutter severely and sound how I can only describe as "robotic." After restarting, it goes back to normal. There are no error messages, the system just begins to lag and affected programs become unresponsive.
Usually when this happens, I notice that my device is unusually hot. Ever since I purchased it, I have never heard or felt air moving in the vents so I'm not sure if the fan is functional. I'm afraid to take it apart to make sure in case that voids the warranty, but I suspect excessive heat might be damaging the components related to this issue.
The default sound device is Realtek High Definition Audio

I recently bought a Thinkpad 540p and wanted to know a way for stopping the battery from getting charged after a certain level. Its a very common feature to stop a battery from charging say after 80% and run on AC power supply directly.
Other lenovo laptops do support it, under various apps like Energy Manager, or Power Manager but I am not able to find any such options/app on my laptop?
the past week my audio has not been working properly (no sounds at all). i'd be able to fix it just by uninstalling and then reinstalling the idt hd audio driver, and then it work fine, but the next day when i turn on my laptop again the same problem happens. i decided to install the update for the audio driver, thinking maybe that would fix the problem. but it didn't. same thing keeps happening, whenever i start my laptop, no audio and i have to reinstall the drivers (i have to reinstall the original driver + the update now to get the audio working).
You can hear this effect around 60%-80%+ volume(varies by system) usually from the right speaker(more noticeable). It sounds like a speaker when its damaged from high volume or a bad amp you hear a buzzing/cracking/distortion sound on the right speaker usually(you can also verify it with the dell audio diagnostic, test my Dell technician even realized it). Ive had 3 xps's replaced(due to other issues) all of them had the same problem (additionally I had 2 speaker replacements and they had the same problem). sxps 1640 and 1645. I remember when a technician came and opened my motherboard I took a look at the side speakers. It seems that the right speakers are loose compared to the left ones. You can press on it and it goes a bit in and out.
I just wanted to start a new thread for Bill to bring this issue also to the attention of the engineers. I think I know what the problem is, I will be putting rubber pads in my laptop to enforce the speakers from vibrating. Someone brought this solution to my attention a long time ago.

Does anyone else have this problem? Verify so Bill can bring it to the attention of the engineers. Bills going to have big meeting with big players soon so post up if you do have this issue so he can bring it to the table. I didn't want to use the throttling thread for this issue.
My temporary solution is not to go about 60% volume... since it's load already but it would be nice to blast the volume and listen to music while doing other chores in the house or hang with friends but the audio quality is terrible.
Note: I can not verify this for sxps 1647 because I do not have one.
I will give you guys an update on my results, when I dampen the system with pads and reinforce it.
Customer has three L440 with Docking station PRO and Samsung 22" S22C45 on DVI
* W7 64BIT Sp1 Lenovo version not VL * Latest BIOS * Latest GFX Driver * All Windows WSUS Updates (Standard Image from lenovo with all Hotfixes) * Power Options set to Performance (lenovo Power manager deinstalled) * Office 2010 SP2, PDF24, APPV client 4.6+ * Dameware 6.X Agent
problem:
Laptop is in docking station with external 22" Samsung DVI and working in Winword, IE or others. Suddenly screen from Samsung turns black (laptop TFT from people who use dual stays on). After 1-10 seconds the samsung screen comes back. We fiest thought this was some RDP issue with other users connecting to the device. (Not the case)
NO > BIOS and GFX is latest and MADE it worser with updating to the latest (happens more often). NO > MHz change from 59/60 or slighty modify did not solve NO > It's not a screensaver problem NO > All three Samsung are from diffrent shippments and even Distributors NO > All three L440 are from different time periods 2-3 Months split
New Latitude E6510 running Win7 Pro 64 bit. Periodically the laptop will boot with a red X through the speaker icon in the tray. Placing the mouse cursor over the speaker icon displays a message something like "No audio device is installed. A cold boot does not correct the problem. Shutting down, disconnecting the power supply, removing the battery then restarting has corrected the problem so far.
When I plug in the AC adapter, my x1 shuts off right away. I have to reset the time in the bios to get it to work again. This happened right after I changed the keyboard. Now, it seems to be permanent issue. I thought it was an adapter issue but I have two adapters and both work fine.
Have a brand new X1 Carbon running windows 7. It originally came with Windows 8 but had to downgrade to run a necessary work application (which could be the problem). My battery never exceeds 50% even when plugged in for extended periods. Also, I am not seeing any of the "Rapid Charge" that was promoted.
I have a ThinkPad X130e that won't power on or charge. I have performed the unplug the power cord and remove the battery trick but still nothing happens. The thing is essentially a paperweight.
I have a ThinkPad Edge 15. It had a charging problem from the day I purchased it. The people I bought it from sent it back to IBM/Lenovo who apparently tightened the area where the charging cord goes into the PC?
That did NOT fix the issue, so when I got my laptop back, I called LEnovo, they sent me a new battery (even though I told them the 'Power Manager' said the battery was in good condition) which did nothing. Then they sent me a new charging cord, again-nada. They sent me a box to send the laptop back to them. As I was figuring out how to put the laptop in the box, I looked over @ my PC, and lo and behold; the light that tells you if it is charging was shining!
Last night. I looked @ the charging icon; '15%, not charging'! Oops! Oh dear, not again! Went to power manager, everything is just fine. Checked all of my connections, same thing. I left the laptop plugged in. This morning as I look over @ the laptop & Guess WHAT! It was charging, the light was on! I turned it on...
