Built-in mic on Thinkpad Edge E545 Win 8.1 not working

OK so when I got this computer shipped to me from school back in November of 2014 it had Win. 7 on it. I had the Windows 8 recovery disc and decided to use that to upgrade the OS. Since that day my mic has been on steriods. I also keep getting the stupid message about the Dolby digital audio drivers not working. I've done everything I could find to to on the interwebs. I had installed the update first and still got it. Then I uninstalled, reinstalled, and restarted the laptop... still got the message. Now I can't even use Skype. PLEASE someone with updated information help! I need this thing to work for school since I have tutoring groups via Skype and such. Many thanks.

Thanks for your answer! I was able to solve the problem by running the pre-installed System Update rather than some of the solutions that had been poster somewhere else in the forum.
In any case, for the record, the path of the file I was referring to is C:\Program Files (x86)\ Thinkpad \ Utilities\ PWMTR64V.dll

After using apogee duet, mac's built in mic & logic's track headers for recording are not working properly. How do I fix it?

I use logic 9
After using apogee duet for mac, I was away from my home studio without the duet and wanted to record vocals via the internal microphone on my mac book pro. (Obviously, I know it wouldn’t be the same quality. I wanted to do it as a draft, because I had a melody in my head and wanted to record it so I could remember it later.)
After opening up a project I was unable to record audio. I noticed the track headers had changed. Sometimes the “record ready” button was missing. But whether it was there or wasn’t, the same thing kept happening… After pressing the “record button” or the “record ready” button a window would pop up that said, “No input source selected!” I tried to trouble shoot by configuring track header and by going to prefereces>audio>devices>core audio, and switched the “input device” to “built in microphone,” and things like that, but I still would get the same pop up window indicating “no input source selected.” To be thorough, in preferences under “core audio,” I have selected universal track mode, 24 bit recording, and software monitoring.
Do I need to reset something?
If your recommendations help fix the immediate issue temporarily, how do I keep it from reverting back to the same problem if I feel like switching between the duet interface and the built in mic in the future? How do I keep it permanently from this malfunction? It seems like this is something simple that would be addressed.
Also, as I was trying to think of anything it could possibly be. I wonder if it could be the driver I installed for an old m-box2 possibly causing an issue. After getting my new mac book pro, I downloaded a driver for m-box2 (the second generation that came out in 2005 and used pro tools LE.) I used the m-box on my previous computer and it worked well. Since I purchased a new macbook, I tried to use it on my new computer, but since the m-box2 is a 32 bit system, it didn’t work very well, which is why I got the duet. I don’t know if that could possibly be messing anything up. If so, should I uninstall it somehow?
Thanks

Ok, think this through... you've changed from a stereo source to a mono source.
The message reads: “No input source selected!”
On the track you're trying to record there is an Input section directly underneath the I/O label. Click and hold to select the correct Input for that track.
Also, the project you opened was saved with the Duet's driver/interface parameters.. if you open the same project without the audio interface Logic will do it's best to pick I/O that's compatible but I've never seen any DAW do this perfectly.. it always takes a small amount of user input. Especially since you've changed from the Apogee to the internal mic.

Varying brightness on my ThinkPad Edge E545

I have a ThinkPad Edge E545. I've only had it a few days but it's brightness varies in and out constantly while I'm using it. I've seen other people have had the same problem but not on my exact computer so I wasn't able to fix it by the solutions given to them. Also mine runs on Windows 7 professional. This is the exact computer: http://www.amazon.com/Lenovo-Thinkpad-20B20011US-15-6-Inch-Laptop/dp/B00FU83YWS/ref=cm_cr_pr_product...
Please help me. Thanks!

What operating system was your machine shipped with? Lets say windows 7.
If it came with windows 7, what is your intent with installing a retail windows 7 on your current machine? Is a purchased retail win 7 or a trial 30 day?
Simple solution:
(1) If you backed up the factory partiton using the CREATE RECOVERY DISC, rebuild your system with those DVDs.
(2) Call the support center and order factory recovery disc with the operating system originally shipped on the machine.
(3) Reinstall win 7 using the 64 bit install disc. And forget using factory install. As long as you have a PRODUCT key to activate win 7, you are good to go. Download whatever software you need from the Lenovo website, install.
I went from Vista and installed win 7 home, retail version. I wiped the whole drive clean during the install. Installed RnR, took a backup to DVD. That is my recovery option now.
Technically what happened:
(1) Factory ship modified BCD (boot control data) to have entries for Windows, Windows RE, and RNR/factory install.
When you use RNR to factory install, it points to a BCD entry to use on reboot. In your case, your system booted into windows RE (recovery environment).
(2) Your windows install rebuilt the BCD, removing the entry to the factory partition. There is another post out here, recently, have the same problem as you. I will post the link to their resolution. It involved installing DEBIAN free software, and placing wim.pe software into the factory partition or such to make it bootable again.
http://forums.lenovo.com/t5/ThinkVantage-Technologies/Recovery-problem/m-p/1190409#M23247
Back to the main question, what do you want on your system today? Retail 64 bit win 7 from retail box?
(3) Opps, it wont boot. Someone is helping me.

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!

ThinkPad Edge E545 - fehlerhafte Firmware

Wann kann man eigentlich mal mit einer korrigierten Firmware für den ThinkPad Edge E545 rechnen?
Seit einer halben Ewigkeit steht nur eine Firmware mit diversen Fehlern und einer überaus kundenfeindlichen Whitelist zur verfügung.
1. Die Hardwarevirtualisierung lässt sich nur nutzen wenn sie im BIOS auf "Disable" steht.
2. Die Whitelist verhindert den Einsatz eines alternativen WLAN/Bluetooth-Moduls.
3. Die ACPi-Tabellen sind ebenfalls nicht ganz sauber.

Sorry to ressurect an old thread, but recently I've been getting random kernel panics on my t61 as well. I believe the root cause is the wireless card. I have an intel 4965 card just like you.

Bios protection from infection with virus or bios recovery of Lenovo Thinkpad Edge e545

I have Lenovo Thinkpad Edge e545 laptop. Among downloads there are no bios images but only backup cd iso file. Does laptop bios somehow protected from beeing infected with virus when OS installed on laptop is infected? If not, is there a way to recover bios from usb flash? Or is there some other way to recover already infected bios without help of technical support center?

Dear Wyacheslav1
Welcome in lenovo community
Actually there is no relationship between the Virus and the BIOS also the BIOS cannot be infected such as the windows . So if you have any debut that your machine has been attacked by a Virus, you can install any antivirus application to scan for this virus and to protect the machine from such attack

E545 and Function key not working

Any help here is apprecited. My function (Fn) key is refusing to work at all. None of the special features are able to be used. I've checked all my drivers, and followed the instructions in the User Guide, but some of the options described in the guide are even showing on my computer.
I'd love for some help on this issue, as the computer is pretty worthless right now.

Hi Jamesbjenkins,

Lenovo Thinkpad E530 - USB 3.0 Ports Not Working Code 10

Hi everyone, so I own a Lenovo E530 with Windows 7 and just earlier today I plugged in my optical mouse into it, about 10 minutes in, Windows gave me a "not enough power message" for my USB 3.0 ports on the left side and they just stopped working. I have 3 USB 3.0 ports on the left side of the laptop, and one USB 2.0 on the right which works just fine.
From there it gave me Code 10 for Teredo Tunneling Pseudo-Interface in the Network Adapter section (which I was able to fix via a registry change) and now what is left to fix is the Intel USB 3.0 eXtensible Host Controller which I cannot seem to fix. I have tried the uninstall/reinstall processes, with Intel's own drivers and Lenovo drivers which were just older version of the Intel USB 3.0 drivers, over and over yet it is still stuck on Code 10, where it will not start.
I never really overused the USB ports either, aside from plugging in a portable USB fan and portable hard drive here and there, and a USB dongle for a wireless mouse and keyboard (Logitech all-in-ones), that is pretty much all I have done with it. I do not believe the ports are not bad or anything, although it may be a hardware problem, but all 3 USB ports still give power on my fan and external HDs when I plug it in, it is just that Windows does not recognize it and nothing happens when I plug something into. But on the other hand, the USB 2.0 port reads just fine and recognizes everything. I have also tried the Troubleshooter multiple times, but everytime it tries to reinstall I get the "Failed" message.
Here is a screenshot of what I am talking about.
http://i.imgur.com/mKqWpFU.png
http://i.imgur.com/RLkbyHY.png
I have tried reinstalling and uninstalling the Intel USB 3.0 eXtensible Host Controller Driver for W7 using the ones listed on the drivers page through Lenovo and using the newest version fround on Intel's webpage as well. Having done these I still could not get it working, so I did a full reformat of the Hard Drive, from there I am able to get the USB 2.0 and 1 of the 3 USB 3.0 ports to work (the very top one above/left of the HDMI port) and recognize devices when I plug them into Windows. But this is working through not having the USB 3.0 Driver installed and just the basic one without having any updates/drivers installed on. Once I install the USB 3.0 Driver back it, it goes back to the original problem.
The problem still persists even though I have done multiple reformats, uninstall/reinstalls, updating to newest drivers and BIOS, etc. I have owned and still own a whole family of Lenovo laptops which still work perfectly fine, but this is the first time I have seen anything like this go wrong in a laptop. Is there anything else I can try to fix this problem? The laptop just went out of warranty a few months ago, and if I were to send it in and get it repaired would it cost me a lot?

Thinkpad Helix - Screen auto rotation does not work (Issue 3/3)

Hi,
I have installed a clean Windows 8.1 on the Helix and have several issues. Putting them into several threads so they can be answered independently.
The first thing I did after installing the system (and critical Windows Updates) was running the Lenovo System Update tool and downloading everything.
Screen rotation does not work. In “Device Manager” I can see “C5621 gw Mobile Broadband Geolocation Sensor” and “Hid Sensor Collection”. The HID one has an exclamation mark next to it. Are there some drivers I need to download to make this work. I did of course check if screen rotation is not locked – it is not (I did turn it on/off a couple of times, without any effect). Manual rotation (using display settings) works fine.
Thank you in advance for any help,
Łukasz
Solved!

Hi Lukasz,
Try, in device manager, right click on HID Sensor Collection then uninstall. Reboot, and see if the driver is loaded properly, if not click on scan for hardware changes.

Win 7 Wifi not working after upgrading to 10.9.4

After the update I am not able to get Wifi connection on my Bootcamp 5.1.2 with Windows 7 Professional. The wifi icon gets a red X and it can't se any network at all where it earlier could se several networks. Its running on a Macbook Pro Retina, Mid 2012 2,3GHz i7. Also my external keyboard is not working anymore when booting to Win.
Everything was working perfect before the update and somehow it seems like the the Apple Windows support software is not working anymore (I am guessing).
I have tried to download the support software again to a USB and reinstall on Windows but no change.
Since I have been reading that there has been a issue with a Apple wifi update on 10.8 I tried the workaround from that thread and restarted the bootcamp in many different ways but still no changes.
I guess that this requires a new update from Apple - but I can't find any way to report this issue without having to pay for it!
Anyone who are experiencing the same or maybe someone who has a solution I would appreciate it - thanks.

After i reinstalled Bootcamp with Windows 7 it was all working fine again with OSX 10.9.4.
The bad news is that I just updated OSX again to the new 10.9.5 and now I am back where I started again - no network connections.
It can't be a coincide that it is the same pattern again and a bit annoying if the solution is to reinstall Bootcamp every time there is a update - hope anyone can give me some hints?

New ThinkPad Precision Wireless Mouse (MORFGOO) does not work

Hello to everyone,
My wireless mouse does not work. The symptoms are: The mouse is completely unresponsive, as if it had no power at all (cannot be turned on, no red laser, no interaction with CPU).
How I came to notice the problem:
I installed the mousesuite from lenovo/support/mousesuite. Then I restarted the computer. After this, I connected the USB Bluetooth Adapter to a USB port of the ThinkPad 430s 2352 CTO. I tried to turn the mouse on. No changes were noticed, Mouse still offline, no light. Tried a different set of battery & tried the wireless button. No change. Reinstalled the mousesuite. No noticeable change.
I believe the mouse might be broken. Could anyone please provide me with support as to how I could solve this? In the case that it is non-functional, how do I return it to lenovo? Is it under my one year guaranty (I bought it as an accessory on my command for my laptop)?
Thanks for your answers!

Hi,
Your migration to Lion brought over a previous hot key preferences document. And this contains one bad key that wasn't updated.
- Quit System Preferences (if open)
- Delete this document to remove a carry-over mapping error.
- Then logout
Note: That this will delete any existing modified keyboard assignments. Re-assign changes manually.
Note2: This document is in your users preferences folder.

Wine and WineBottler not working. How do I fix it?

Hello, everyone. A few months ago I downloaded Wine so that I could run Windows files and applications on my computer. However, recently, it's not working. No matter how many times I tell Wine to run the file, nothing happens. X11 doesn't start or anything. I've even tried uninstalling and reinstalling Wine to see if that worked but it didn't. Could someone tell me what to do so that it works again? Any help provided will be appreciated. Thank you.

lol, I know it blows, but sometimes you need to stop trying to run emulators for such needs and actually run the respective OS you need. Wine or X11 will not run 100% of all Windows based programs, so you can't expect it to run everything. If you find yourself needing better Windows support, then I suggest something like Parallels 8 and a copy of Windows as a VM alongside OSX. Much more reliable solution.

Who has a good docking station for ThinkPad Edge E545?
