Y700 15ACZ Subwoofer not working

Q: Y700 15ACZ Subwoofer not working

Hello i own a Lenovo Ideapad Y700 15ACZ for 3 weeks now. But the subwoofer is definitly not working. Since it came out of the factory it did not work.I reinstalled drivers from lenovo support page and have Dolby installed and latest Realtek drivers. Is this a harware fault? or is it something else?I can also see in sound->playback devices->speakers (realtek high definition device) an internal subwoofer slider. This has 0% impact when set to zero or fully enabled. ?? Can someone help me please? (In dolby i can't change anything only an equalizer.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Are you sure it's not working?   I thought the same when i bought mine new, but i was wrong.   It's only a 3watt sub so its barely noticable in my opinion. There is an area where you can control the volume level of the 2 speakers and the sub.  Make sure those are both up.  Speaker Properties-->Levels

Is it available on this laptop? AMD website states the FX processor as being dual graphics capable, yet i can find no driver package that enables CROSSFIRE. GPU-Z states "Crossfire Available" but is disabled. What gives? I purchased this laptop for this reason. Is this a windows 10 issue, the AMD website under features states windows 7/8 but does not list windows 10. Also, BOTH the r7 and m385x list freesync on the amd website but i can find no driver package to turn this feature on. Please assist.

I jave the exavt same laptop, and I have yet to determine how to enable it, though not for lack of trying. If you downlaod a program called "GPU Z" is has a section that says "Crossfire Available (Disabled)" so it seems it CAN run it. Though additionally, in the new AMD crimson app, under Radeon settings, it shows that the graphics drivers are linked.  Crossfire may not be available as a feature per se, but maybe it's doing it naitvely anyway?

Hallo, in other threads there was already mentioned the tool AmdMsrTweaker.While most people just set lower voltages i also changed the clocks of non-turbo-clock-range.So it is impossible that the CPU clocks lower than the default 2.1 GHz. To savely change the clocks you have to be sure that you are not in the changed clock range. Otherwise Windows will suddenly crash.I wrote a VBScript to check if you are in the turbo-clock-range that is untouched by the config.You should be sure that you CPU is running at 100% clock speed. (Windows Control Panel) Here is the Script for AmdMsrTweaker that has to be saved with .vbs-extention.On Error Resume Next

Set WshShell = WScript.CreateObject("WScript.Shell")

Do Until CurrentClockSpeed > 2000
Set WMIService = GetObject("winmgmts:\\localhost\root\CIMV2")
Set CPUInfo = WMIService.ExecQuery("Select * from Win32_Processor")
For Each Item in CPUInfo
CurrentClockSpeed = Item.CurrentClockSpeed

Hey everyone I bought this same laptop and I am having the same issues that where discussed here I have the fx8800p model with r9 M385x.  Heatup to 80-85c then throttles hard loosing ~10fps  This is copied from that post which discribes what issues Im encountering http://forum.notebookreview.com/threads/ideapad-y700-15acz-review.783192/    "Theoretically the performance is very good with framerates between 41 and 47 fps (~43 avg) but after 20 minutes i experienced heavy frame drops (last screenshot). Those are caused by the CPU that throttles down to 1,4 GHz for a few seconds and thus makes the game unplayable. No tools i checked would show the CPU temps so it is hard to say what the cause is. The GPU reaches 85 degree max. and this seems to be the point where the system starts to throttle and even GPU clock speeds are lower than they should (700 - 900 MHz)." I Would love to use this laptop to game on as it does give good proformance but as the cooling setup doesnt not seem up to the task.  Also this is what Im seeing.  I have yet to see the r9m385x run at 1000mhz ever and the memory is always at 1200mhz not the 1500mhz amd says it can be used at.  I really dont understand how this product can come out with such heat issues.

Hello! I have a Lenovo Y700 15ACZ Gaming Laptop with 8GB DDR3 RAM that I recently upgraded to 12GB DDR3. A few months before I upgraded (when I check task manager) it reports that my RAM speed is 800 MHz i instead of the 1600 MHz speed advertised! So, I thought upgrading the RAM, as I said, would fix the issue. BUT it didn 't. So, what I just want to know is, if my RAM is underclocked does that mean my computer is dying? I'm perfectly fine with the underclocked speed, as it doesn't affect my gaming performance. I just want to put an end to this mystery, though. So, any help would be appreciated!Thanks! :-)

Hello all, I recently bought a Lenovo Y700 15ACZ(the AMD model of this laptop which sports the AMD FX APU with the R7 integrated graphics and the R9 M385x discrete/dedicated graphics). Anyway, I recently installed a fresh copy of Windows 10, I installed my games. They all run but I can't tell if they use the r7 or r9. So for example, I have everything set in the AMD settings to use the "High Performance" I have also adjusted the power settings to "maximize performance as well. The device driver versions on the r7 graphics and r9 graphics are currently matching. So anyway....I go to launch a game(GTA 5 in particular since I can easily see how much graphics memory is available...this game was set to use the high performance graphics) anyway, I ran the game and went to the settings to adjust the graphics settings....it showed I only have 1024MB graphics(integrated....since the r9 has 4096mb) How do I get games to use the R9 properly or how can I tell if they are. Any help appreciated! My first install of Windows I got the drivers from AMD's autodetect and got everything up to the latest, I reinstalled(for a few reasons) and now have the drivers in from Lenovo, BIOS is also up to date and set to use discrete(instead of UMA). Looking forward to replies from other y700 owners, thanks!

Hello. I just purchased a Lenovo Y700- 15acz that's having issues playing games. I'm getting alot of microstuttering even though the frames remain strong in all games. From what i have researched, it seems this issue is connecting with the latest bios versions. My machine came preinstalled with a newer version(pre new logo) and not the original bios. I updated to the latest(new logo) hoping the microstuttering would stop but the problems persist. Scourging the web and the Lenovo site, i haven't been able to find the old Bios. It looks like the problem is tied to the GPU frequency clocking down rapidly from 900mhz to 600mhz  several times during game play, probably a feature to reduce thermal throttling. It seems Lenovo went with some type of preventative throttling rather than heat throttling, but the results are the same if not worse. I'd like to know if there is a way to reinstall the old bios. i've checked the bios and enabled the bios downgrade option, i just can't seem to find the file. If anyone from Lenovo or the community can provide me with the old Bios file(stock versio) i would greatly appreciate it. Thank You!-Chris

Hello everybody! I am interested in buying the new Gaming Laptop Lenovo ideapad Y700-15ACZ in the TOP version with FX-8800P and 4GB R9-M385X. As I have seen, first offers come only having the 1TB WD slim hdd. So time to find out which will be the best M.2 SSD to add nearby. For this need to clarify first if the M.2 port is connected to the SATA III of the FX-8800P's internal southbridge only or if it has connection to PCIe lanes. The HMM https://download.lenovo.com/consumer/mobiles_pub/ideapad_y700-15acz_hmm_201508.pdf tells on page 26 there is PCI Express Gen3 and SATA Gen3. For the hdd is written SATA III as note and for the ssd it is NGFF which means the same like you write M.2, so it is unclear. Btw - there are NO DDR4 ports on that model yet. On page 64 you find some oem M.2 ssd models that Lenovo offers to add. Those are SATA3 models like LiteOn CV-1 and Samsung PM871 with keys for "B+M". But this also doesn't mean anything more than might be badder choices. Have a look at the mainboard on page 48. You can see that the M.2 connector has only key M (right side) which means PCIe 3.0 (cpu) + SATA whereas key B (left side) would mean PCIe 2.0 (southbridge) + SATA. That M key port would allow to put in ssd cards like the Samsung SM951MZ-HPV (AHCI) model which might be the fastest using AHCI+PCIe or even the newest model Samsung SSD 950 pro which uses PCIe 3.0+NVMe only. But if there exists only a SATA III connection, the key should be "B only" instea... Read more

As there are a lot of cloners around, you may try each at which ever works for you the best.
 
Do not delete or change the original drive yet until you have verified that the cloned drive works as expected after multiple restart and cold boots.

Hey everybody, this is for all of you that bought the Lenovo Y700 15ACZ gaming laptop with Amd FX 8800P processor and are having an issue with the CPU throttling.  I bought this laptop a little over a month ago, and right out of the box, it didn't perform as it should.  It throttled down from the full 3.4ghz to 1.3, and I encountered a huge drop in my framerate while gaming.  I would start a game like Battlefield 4 or Farcry 3 and have pretty good framerates for a laptop, something around 35-40, but after playing for a while I would see my frames go down in the teens.  I knew there had to be a problem, and a solution.  I've done a ton of research on it from the time I got it until now, and I finally have the answer, thanks to numerous posts on the Lenovo community.  It takes quite a few alterations, but it helps, I promise. First, you need to make sure that all of your settings are set to High Performance.  Do this by going into your Radeon Settings and clicking Preferences on the bottom.  Click Radeon Additional Settings and in the Catalyst Control Center make sure that anything you can change to performance is set to that.  High Performance is what you want, so when you open a game it will switch over to your dedicated GPU, which in this case is a Radeon R9 M385X.  One other thing I noticed is that Catalyst Control Center takes up roughly a steady 30% of your CPU us...

Hello, I recently bought this laptop, and I'm having some problems. This was advertised as a gaming laptop, and for the games I play it should be more than adequate. However, in some of my more demanding games such as Armored Warfare(I play on medium settings) I get heavy throttling, drops from 60 fps to 30-40; when it drops it's heavy stuttering and lag, making it un-enjoyable to play. Also, half the time I can't even tell if it's using the dedicated or integrated GPU, even when I have my performance settings to MAX. It seems to be no option to switch off the intergrated GPU completely, since Mantle isn't really supported anyhow,  That being said, my main concern is the GPU throttling. Is there any solution, I noticed this is running on a 15w TDP according to CPU Z, that is very, very concerning to me. Is there any BIOS fix or anything I should be aware of, I don't want to return it, but I'm tempted to.

Hi all Please some advise. I have the Y700-15ACZ (FX-8800P, M385X 4GB). While gaming, the GPU clocks go down to 300MHZ from time to time (about every 2-3 seconds). I don't see why - the TDP remains the same according to HWInfo and the temps are quite ok.I even used MSI Afterburner and downclocked the GPU to 0.5GHZ/1GHZ (core/memory) which is a lot lower and it still happens (and TDP/temps are much lower too). Any clue? I've tried several drivers from Lenovo and from AMD and nothing helps. The performance is actually quite ok, except these jumps in clocks..Thanks

In my first post i posted about y700ACZ throttle. it was very serious throttle from 3.4ghz to 1.3ghz while playing games. To FIX this follow my words. 1.Its not the gpu or the apu that is throttling nor any other hardware flaw. 2.Its the AIR intake vent. TO [email protected] remove the hood and look upside down there you will see a cloth like fiber cloth covering the vent THATS the main reason of throttling. 3.remove the cloth carefully leave it open and run any of your game.look  at the cpu in task manager 4. i played assassin creed syndicate for 1 hour and was no throttle even the gpu temperature was @60-65c 5.there are some lag in games though which is barely seen but what i think is its bcuz of 15w TDP !! but thats ok not an issue 6.ALSO I RUN HEAVEN BENCHMARK AND @EXTREME SETTINGS I GOT MIN 20FPS AND MAX 45FPS 7.BUT FIRST OF ALL DO CLEAN THE FANS AND ALL OTHER PARTS. SO CONCLUSION THE MAIN CAUSE IS THE DESIGN FLAW AND ITS LENOVO'S FAULT NOT AMD SO AMD !!ROCKS!!

I'm a huge gamer and I don't care about fan noise, on my desktop the GPU fan is usually at 100% while gaming which is quite loud, even bought a externel fan for this thing and it's not enough, gaming performance is lousy due to heat, and I also complete SETI projects regularly, not a fan of my GPU constantly being at or above 80c thanks for any help.

The problem is the following:If I enable discrete graphics and then install video drivers, windows startup fails as soon as I restart. If I use integrated graphics, install the drivers then reset and enable the dedicated gpu, it boots just once and I can see both the r7 and r9 in device manager with a yellow triangle. Then windows installs drivers for the R9 and asks me to reboot. Once I do, windows startup fails once again.With no video drivers installed, it boots just fine using some generic windows drivers.The only way to get it to boot is safe mode or by using only integrated graphics.I just don't know what to do anymore. I've tried windows 7 and windows 10 and multiple versions of AMD drivers.
