Q: Lenovo Ideapad 710S - ACPI Driver Not Installing -...

Lenovo Ideapad 710S's ACPI driver just got updated on 14 Sep 2016. However, I can't get it to install. Its installer closes immediately upon launch, similar to the cases here: Lenovo G580 Windows 10 ACPI Driver not installing and Y500 ACPI driver not installing. ACPI driver: Laptops-and-netbooks :: 700-Series :: 710S-13isk - Lenovo Support (SG) -Advanced Configuration and Power Management Interface (ACPI) Driver for Windows 10 (32-bit, 64-bit) ... Any advice is greatly appreciated.

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.)

Today, I updated my Realtek Audio Driver to version 6.0.1.7831 (dated 7/21/2016). After installation, I immediately realized that the taskbar icon changed from Dolby to Realtek default icon:? -> ? Next, I went to Programs and Features and found out that "Dolby Audio X2 Windows APP" disappeared from the list. Originally, both of these Dolby programs came with the laptop:? After the update, I was only left with this:? The impact of this is that I can no longer toggle the different sound features provided by the Dolby App. I contacted Lenovo via online chat support but the personnel insists Dolby is not a supported program by Lenovo without giving me a valid solution or answer. Did Lenovo omit Dolby App in the latest Audio Driver by mistake? Or did Lenovo intentionally removed it due to the vulnerability explained here: "Dolby Audio X2 (DAX2) privilege escalation" https://support.lenovo.com/sg/en/product_security/len_4884#/IdeaPad. If anybody is facing the same issue / has any solutions / answers, kindly leave a comment below. Thank you.

I download the :Advanced Configuration and Power Management Interface (ACPI) Driver, from the Lenovo website: The link for the driver ( for Lenovo y700-15ISK) :
 
 Click here
 
I download, give permission to run, then nothing happens; no installation wizard, nothing. This is the only driver I haven't been able to update, and it is the one that is causing me serious problems with audio latency, as Latencymon v 6.50 tells me. I get crackling sound from speakers, but when I disable the ACPI driver, the crackling goes away. The problem is that if I disable the ACPI driver, I am no longer able to see my battery status. So it is important that I update this driver. However, I don't know how it is possible that the driver provided by Lenovo does absolutely nothing at all.
 
Mod Edit: Corrected the text format so message displayed correctly
 

A:Lenovo y700 ACPI Driver, not installing

The fix for this is to go to safe mode (on windows 10) : Settings-> Update & Security-> Recovery : press restart now -> After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options >Startup Settings > Restart-> After your PC restarts, you'll see a list of options. Select 4 or F4 to start your PC in Safe Mode. then in safe mode go to device manager ->System devices  right click on Lenovo ACPI-Compliant Virtual Power Controller  -> Uninstall  Double click on the ACPI Driver you downloaded. this should fix the problem.

I noticed that new drivers were released for G580. The drivers (Lenovo Enegry Management Driver) canot install because when the installer starts up, it immediatelly closes. Do I have an issue somewhere? Windows 10 (1511, Build 10568.17)Lenovo G580 (20157)

A:Lenovo G580 Windows 10 ACPI Driver not installing?

hi acemod13,
 
I looked at the Lenovo Energy Management driver for Windows 10 and upon observing the installer behavior, it extract the ACPI driver files (58KB) to C:\ProgramData\Lenovo\ACPIDriver (this may explain why the installer closes right after extracting).
 
If you're seing an Unknown Device in the Device Manager with an ACPI hardware ID (see image below) then try to update the driver manually and point it to the C:\ProgramData\Lenovo\ACPIDriver folder
 - Sample image
 
If you're unable to see the driver files, I've uploaded them here.
 
 
Let me know how it goes.
 
Regards

I am totally disappointed in Lenovo's customer support. My lenovo 710s was bought less than 1 year ago (as of 10/6/2017, when I sent it in for repairs) and had 2 years warranty (1+1 year of extended warranty). I sent my laptop for repair due to a white spot issue on the monitor, affecting viewing of webpages and videos. However, the laptop was returned after 3 weeks without any fixes/repairs, as Lenovo claimed that it was a cosmetic issue. I wrote a message on their customer care website on 3/7/2017. However, they ignored me and there was no reply to date.  I thought Lenovo is a reliable and popular brand. However, it turned out to be a horrible decision, much to my dismay!

Okay so I've had this computer less than 3 months and it's given me nothing but problems. Now it refuses to even turn on. The power LED turns on but the screen remains blank. This is an non removal battery type before anyone says remove the battery and use the adapter. I've drained the battery which has worked before but this time when I try to charge it the orange battery LED blinks three times. And still nothing on the screen. Any Lenovo stores are quite far away. Anyone knows what's going on?

Hi  I am thinking of purchasing a 13" Lenovo ideapad 710s ($1199 model) over a MacBook air. I have been using a macbook air for several years and recently thought of getting a new laptop. Lenovo's 710s seems to be quite good on paper (except the battery life), but I couldnt find any reviews online which can tell me if the laptop is as good as Lenovo projects it to be. If anyone has bought/used Lenovo 710s, can  you guys chime in and let me know if this laptop came on par with your expectations (esp. the battery life)? Thanks

A:Lenovo Ideapad 710s question

hi. Here I leave you computer manual so you can compare, the battery is a consumable device that usually lasts depending on the use that will give the team being new can last an average of 3 hours, you should know that each load you do it is that you take away useful life. https://forums.lenovo.com/t5/Z-Base-de-conocimientos/Optimizando-el-tiempo-de-duraci%C3%B3n-de-la-ba... Manual service:https://download.lenovo.com/consumer/mobiles_pub/ideapad_710S-13ISK_hmm_201603.pdf Regards.

Dear Lenovo Community, I've just bought my Lenovo Ideapad 710S two days ago. Bought the highest-end configuration with 16GB RAM + 512GB PCIE SSD. I got to say I'm absolutely in love with the form factor and its performance. I decided upon this laptop mainly because of its portability and the combination of 16GB RAM + 512GB SSD at less than $2k. DesignAt 1.1kg, it is really light - I can hold in up effortlessly with one arm. At home, I use a Dell monitor (U2715H) which is almost borderless; looking at 710S's edge, it is equally slim and is key to making it look stylish. The matte screen display has very crisp, clear text and is very comfortable to look at. PerformancePerformance wise, there is no complain. It lives up to what it's spec-ed on paper. Every application and operation (e.g. startup, shutdown, boot from sleep) loads at breakneck speeds thanks to its PCIE SSD. I've yet to try running more intensive software e.g. the Adobe suite but at this rate, it looks promising thus far. AccuType KeyboardAt first, I thought the flat keys have really little travel to bottom-out but as I spend more time typing on it, I gradually grew to like the keyboard. It's well spaced-out, typing on it can be very accurate. Key travel is reasonable for faster typists. Only thing is the placement of backspace, enter and shift button at the right side needs some extra time to get used to it as I find they placed more to the right than it is on comm... Read more

Hi there! I have a Lenovo Ideapad 710S that has really bad sound quality all of a sudden.When plugging in headphones the sound works great, but unplugging them makes the speakers on the laptop sound tinny and very low. It kind of feels like when you walk past people with earplugs that has full volume on. That "distant" sound. Almost as if my own headphones is still plugged in and lays beside my laptop or something.I've tried searching for a solution to this issue, without any luck at all. Can someone tell me what or how the problem may be solved? Maybe the speakers is bad and needs to be replaced, or can it be software issues?

When something plays, the speakers indicator shows as on 'sound' screenshot attached. I am really lost here, can anyone please give soem advise. I read on some forums that there might be some conflict between Microsoft and Realtek driver versions. Perhaps, the directory to where the drivers are isntalled is not proper.

Hi there, Frevans                       -
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
Just to verify, did you encounter this issue the first time you setup the PC or you just encountered this lately?
 
If it's just lately, can you try one of the following?
 
Disable "hide pointer while typing" under Control Panel (large icon view) > Mouse > Pointer Options Tab and enable "Show location of pointer when i press CTRL key"
  - Link to picture
 
Uninstall the Touchpad Driver (ELAN or Synaptics) under Control Panel > Programs and reboot. Upon logging back in, Windows will use a generic touchpad driver. Try to observe the mouse pointer behavior and observe (you can always re-install the touchpad driver by navigating to D:\Drivers\Touchpad or by downloading the driver from the lenovo website).
 
Boot in Safe Mode with Networkingand observe the mouse pointer behavior. If all goes well, perform a clean boot and observe. If same problem, perform a System Restorein safe mode to undo any possible updates that was installed on the system (ensure that you make a backup copy of your files).
 
Update us how it goes.

A:Y500 ACPI driver not installing

Try enabling the MS driver you disabled. You shouldn't turn it off. You are likely running non ACPI mode and getting it back may be a problem now. If you have a restore point from before it was disabled it would be you best approach and then try to update that with the Lenovo driver.
