Lenovo P/Y/Z Series :: IdeaPad P500 - Sound Stops Working After 5 Minutes
Jul 14, 2014
All of a sudden, my Lenovo Ideapad P500 (running Win 8) is having sound issues. The sound will stay on for 5-10 minutes when I start it up or put it to sleep and then wake it up. After that, the sound will just quit working? FYI, the Windows 8 updates that were part of the Microsoft monthly security fixes were installed last week and the problem started today?
The issue was in regards to WiFi not working properly on my Lenovo ThinkPad Yoga S1. After a restart my computer's internet (with WiFi on) would work for a few minutes then it would stop. Long story short, I tried various things, and even uninstalled Norton and other software which I thought may have been a culprit but still the same issue. I also used a USB to Ethernet port (since there is no built in Ethernet port in the ThinkPad Yoga) and connected my computer with a cable and disabled the WiFi to see if it was the wireless hardware not working. Unfortunately still the same issue.
Finally I noticed in the Windows Task Manager a process called "Discover.exe". It turned out this was using some noticeable amount of CPU and wondered what this was doing as I hadn't seen that before. I found out that this was a piece of software bundled in with my computer called Lenovo EMC Storage Connector. I'm not sure why it was running but I ended this process.
Suddenly my internet was working again! This time no problems. I uninstalled this software utility to make sure this doesn't cause this issue again.
I have had my Ideapad U410 for about 18 months now.
Recently my bluetooth mouse has stopped working after a few minutes of use. If I switch the mouse off and then on again it works again. I assumed that it was a problem with the mouse so I purchased a new one.
Guess what. The same problem.
Now with two blutooth mice displaying the same problem I am guessing that the trouble lies within the laptop, but what to do to identify whats going wrong.
I've had my IdeaPad Notebook P500 for over a year, and rarely had an issue with it. Today, I accidently touched the F11 key, which happens to be the "Brightness minus" key.
Immediately, the screen went very dim, to the point where it actually hurts my eyes to be typing this.
I can adjust the brightness sliders up and down on the screen, using both the F11/F12 keys and the slider box available from the "Brightness" selection under "Settings". Even though the sliders go up and down, the screen stays the same very dark level.
Windows 8 64-bit is my OS.
I have uninstalled and re-installed the Intel HD driver.
I have shut down the laptop and turned it back on while holding the F12 (Brightness plus) button. It was useless, though.
Windows did an update today, and now my pc won't run on battery power. The battery icon is just empty and says plugged in and not charging. This is the first time I've encountered this problem. When I unplug it, it immediately dies.
With my Lenovo P500 IdeaPad I CAN connect via wifi but NOT with ethernet cable. It just stopped working one day. Windows 7 device manager no longer recognizes device. I assume I need to replace the ethernet card. True? If so, is this possible or is it part of the motherboard?
It was working fine a few minutes ago, i closed the laptop for a few moment, but when i came back the screen was black at first. so i did a hard shutdown cause i though the computer crashed or something. but when i turned it back on, it was suddenly white. if i tilt it a bit, it sometimes goes black. I don't know what to do, i used my friends monitor and it worked so it not the computer...
Ideapad P 500 Touch - What driver do I use? I tried em8.08.0.2.4 driver. It will not work. It also has caused an error using my function keys on my key board. Error message:
"Compatibility issue between your power management system and Windows Your power management system isn't compatible with this version of Windows. The model name of your power management system is Lenovo ACPI-Compliant Virtual Power Controller."
I'm using Lenovo Ideapad P500 for 16 months now. Windows 8.1.I've had this message saying "display driver stopped responding and has recovered" while on startup on my notification area. It's been quite a some time I have seen this messsage during startups. And, my laptop seems more slow during startup. I've tried "sfc/scannow" but the system seems fine. I did Disk cleanup and optimization regularly. No third-party software installed.
My laptop heats up. Its working fine not too hot during Morning and Evening, but heats up high during day time. I'm not using laptop cooler now, but I've ordered one. My laptop is getting old.
I have trouble with my audio driver on my lenovo laptop. After I updated BIOS to version 1.21, my sound stopped working. I tried to reinstall audio driver, but when I reboot my computer, sound is not working again.
I read about flashing BIOS back, but I dont know where to download old version.
I bought my lenovo Ideapad Z510 about 1.5 months ago. Since a week the laptop stops spontaneously. At a certain moment the laptop stops and is completely off. The first time I immeditely checked if anything was hot, but the latop felt only just a little warmer than my hand.
I noticed that it occurs more often when it is on the AC adapter, but also when running on battery. I checked the temparature with 'speedfan' and the HD0 was about 39 degrees and the 4 cores where about 30 degrees.
I have a y550 ideapad (gpu gt 130m) and i have a problem which is similar to others: when i play a game, after sometimes, from 5min to more than one hour, the pc crashes (black screen, but with backlight, harddisk still running, sound buffer played again and again, no response from keyboard) and i have to switch off the computer to start it again and everything is ok.
So i have tested my ram and gpu ram, no problem
I test the temperature - log of gpu-z: Ok except one thing, at the very end, just before the crash, the GPU memory clock goes from 799.2 (which is the speed during gaming) to 800.00Mhz and the temperature goes from 66°C to 255°C instantly. So there is the bug, software bug?
I want to manage the speed of the gpu memory (to put it max to 799.2) but there is nothing in the BIOS....
I updated my Lenovo P500 touch lapyop to Windows 8.1. The hot keys do not function. I already updated my BIOS to V 1.21. I also had a problem with my screen brightness. I updated my driver for the display. What do I need to do to fix this?
For the first week or two it worked fine and everything was going really well. Then about a week or two ago it started acting up. It is freezing programs(firefox, IE, Chrome, explorer, Flash CC, blender, and a few other programs I needed to install for school. It sometimes freezes on startup and I have to hold the power button down to restart it. Sometimes when it restarts it takes 10-15 mins to fully boot up and load up to the login screen.
After connecting to the internet on my laptop(Dell inspiron 1525, Windows Vista), the internet connection will work great for 5 minutes or less than it slows down drastically or essentially not working at all. If I disconnect and reconnect it will work again but just for a short amount of time. The wireless connection works great on other laptops, tablets and mobile. I have Mcafee antivirus, and it could not detect any malware or viruses. Tried restoring the computer to factory settings and the internet stays connected for what seem a few minutes longer.
For about week I have problems with sound device, so that no sound is played. When I start my notebook it works few minutes, then it stops and when I wanna to test it it gives me error message:
"The device is being used by another application. Please close any devices that are playing audio to this device and then try again.", even when I have no programs running.
I tried all solutions that I found. Disable device, enable divace, restart Windows audio service, Troubleshooter. One think that work (sometimes) is to restart my notebook. But constantly restarting isn't quite the solution I'm satisfied with.
My U330P is running Windows 7 with the latest drivers for both the Intel HD video module and the Realtek audio chip. I would like to connect my machine to a TV via HDMI and have it both act both as the display as well as the audio playback device (i.e. TV speakers should blare, not the ones in my Ideapad).
The thing is, I don't have said TV yet and if what I want to do is not possible, I will not bother buying it. I already did look around in Control Panel -> Sound -> Playback in order to find out whether there's an option to set the HDMI port as a playback device but found nothing. I also have the playback devices menu display disconnected and deactivated devices, but the only thing showing is the built-in stereo speakers. The listings in my device manager don't suggest something like a "digital sound whatnot" either.
So in general whether the audio signal can be rerouted to the HDMI output connector on a U330P.
I've updated my Intel Wireless LAN Driver to 18.104.22.168 and since then every time I close the lid (I'm connected through a OneLink docking station) the wifi stop functioning normal (connects to network but shows "Limited" and practically not functioning). If I open back the lid everything goes back to normal, either directly on the laptop or while still working through the docking station.
I cannot get any audio from my IdeaPad. When I randomly select a mp3 and try to play it with Windows Media Player, I immediately get a mesage that the sound device can't be found or is busy (or something to that effect). I also don't hear sound from internet videos or system sounds such as the start up song. The sound is not muted and volume is at 100%.
I have uninstalled the device drivers for both the Connexant audio and microphone, reloaded them, and rebooted. Same problem.
My question, of course, is: restoring sound from my computer short of a system reset?
I just got a new Ideapad U530 touchscreen laptop yesterday. After a few minutes the keyboard stops working. I uninstalled a few of the Lenovo multimedia programs I don't need. Is there a bios update or a driver I should update after purchase?
Both me and a friend of mine have Lenovo W540s. Everything was working perfectly fine with all of our hardware, until today. A BIOS update came out and installed correctly on both of our machines. After this update both of our UltraNAV features on the trackpad are all dead. After that first restart a message appeared "finding new hardware" and it found a generic mouse on the laptop. Now when I try to re-install the UltraNav drivers, it says no hardware found. I tried both the drivers on Lenovo.com and the manufacture's website all with no luck.
The fan on my IdeaPad Y570 has suddenly stopped switching on. It does not spin regardless of temperature, and as a result, temperatures reach 90C+. The dedusting mode works fine, the fan spins up as expected for the cycle, and sounds normal. So the fan is not physically broken or clogged. I have also installed 3rd party software CPUID HWMonitor to check if the temperature sensors are functioning, and they all show temperatures at expected levels, and more than high enough to warrant the fan coming on.
I don't think I have installed any new software that might interfere with it. I have tried re-installing the Lenovo Energy Management software. I have also tried starting the laptop in safe mode, to no effect.
I've installed win7 64bit on my Ideapad S410p. The problem is 2 USB3.0 ports can't be used, only 1 USB2.0 that can be used. The driver was installed and nothing wrong. In order to use USB3.0, I need to plug in the device and then restart my laptop. I must do that every time plug to USB3.0.
I was using my laptop today and tried to connect to a wireless network. However, my network connections does not allow me to connect to it, and when I tried to troubleshoot the issue, it told me that I needed to plug in an ethernet cord. Looking under the control panel also showed that the option for wireless had disappeared.
I have a Ideapad Y560 laptop, I had some issue with the battery yesterday. It worked fine until I shutdown the laptop last night. The laptop just powered off when I unplugged the AC, with battery installed. And of course I cannot boot the laptop without AC now. I installed power manager, and it says no battery installed. The battery worked fine until yesterday. When I plugged AC in, the meter shows it is charging, but the power volume is not going up. Is it a battery failure?
I just got a my brand new laptop from Lenovo but only the integrated graphics card is running and to make matter worse it crashes from time to time. The laptop has windows 7 installed.
Here's what happened: Google sketch up test 1) install google sketch-up 2) run it for a while and then the screen goes white 3) error pops up stating that the integrated graphics has crashed 4) restarting sketchup is needed to continue
I tried the following to fix this: 1) reinstall the graphic card drivers from nvidia site 2) charge power management to max 3) set google sketch up to only use nvidia GPU (nvideo control panel)
Next I figured maybe it's sketchup with the problem so I downloaded a PC bench mark program - Maxon's Cinebench. this didn't work either 1) Does not see the nvidia card as an option to test 2) Setting it up to run only nvidia grpahics had no effect 3) I'm getting a crappy 17 frames per second - at least the ingrated graphics didn't crash this time..
I recently bought an IdeaPad Z570 and re-installed Windows 7 completely. I installed all the necessary drivers and software available on the Z570 drivers download page, including the Lenovo Energy Management Software.
The following software were not installed as I do not have any use for them:
Everything is working fine except the One Key Theatre button. When I press it, nothing happens. I did some research and found out that the key should be enabled by the Energy Management Software, but it is not the case.
There were also some posts regarding a stand-alone One Key Theatre driver, but I cannot find any such thing on the Z570 drivers download page. Just to confirm, I do not have any "unknown device" in the device manager and the version of the Energy Management Software I installed is the 22.214.171.124 from 2011-03-29.
