Lenovo ACPI driver not installing

2016-02-07, 17:18 PM

I've been trying to install Lenovo ACPI driver ver. 1.5.0.14-20150824 for Windows 10 on two machines, a U430 Touch and a Yoga 3 14 and I wasn't able to install it. I run the executable and nothing happens. Any idea why is this happening?

That answer is not helpful.  

 

I have the same issue with Yoga 900.  The problem is not with locating the driver update.  The problem is actually updating the ACPI driver on the commputer. 

 

  1. Please address how to identify the current ACPI driver version on the computer
  2. How to verify that the current update is installed properly.

 

Thanks.

I agree with nopain4u.

 

And I found that the driver files had a version number 1.5.0.14-20150824 on the web. While the file I downloaded had a version number 1.0.0.0 named acpidriver.exe .

I mean this driver had been updated a lot versions shown on the webpages but always with a 1.0.0.0 version shown by the file downloaded.

 

Anyway, I got no sign to identify whether I had installed it or not.

Nobody from Lenovo has any idea why they released an ACPI driver that can't be installed?

Hi, agreed. the ACPI page:

http://support.lenovo.com/gb/en/downloads/ds105474

and the driver download page for my yoga 2 13:

http://support.lenovo.com/gb/en/products/laptops-and-netbooks/yoga-series/yoga-2-13-notebook-lenovo/20344?isdetect=true&beta=false

both claim you are downloading driver version:

1.5.0.14-20150824

but both downloads are actually version

1.0.0.0


When the file downloads and is executed, nothing seems to happen.


Also the site states the driver is released on the 2nd of March, which is misleading and incorrect, as even the correct driver (1.5.0.14-20150824) was evidently released before then (re: forum date, file date).

So Lenovo are claiming a new March release, suggesting the drivers are updated more frequently than they actually are..

..and at the same time providing the wrong driver version (v1.0.0.0).. which when executed seems to give no feedback on what it's doing ( good / bad / nothing).

This is dangerous, misleading, and irresponsible.

Lenovo, please give feedback.

My ACPI is causing my screen to repeatedly jolt in brightness an arbitrary steps many many times and something must be very wrong.

Please sort out the correct Windows 10 drivers and remove the misleading / dangerous misinformation.

Thank you.

I'm having the same issue. The installer exits without any trace and no errors logged to the event viewer.

 

Lenovo, what do we do?

same problem as described. I checked the content of installer win 7zip and manifest shows driver version 1.0.0.0.

 

This outdated driver couses many issues on my two different lenovo devices (miix 3, 100s) like self-unmounting sd card, wrong battery infos, rapidly screen brightness changes etc. 

 

Lenovo, please update this driver immediately!

Hi all,

 

I thought this would be a problem with me too (I have a Yoga 500-14ISK) , but I think that the drivers are actually updating. They don't seem to be helping my random blank-screening issues but I found an ACPI device in Windows with a version matching what Lenovo has on the site at the moment.

 

In device manager, choose "Lenovo ACPI-compliant Virtual Power Controller" and open the driver dialog. Click the driver details button and it should say the version is 1.5.0.14 or similar, NOT 1.0.0.0.

 

(See Image here: http://i.imgur.com/c9CrK2H.png?1)

 

The TL;DR is that I think Lenovo isn't updating their installer manifest to reflect the new version but that the new files are somehow still being installed.

Re: Lenovo ACPI driver not installing

Possibly it works for some and not for others?

 

1) Lenovo website driver download broken currently

 

2) Zip downloaded previously from Lenovo website: V1.0.0.0 !

 

[somthing very wrong]

 

3) Thanks for your reply and ideas.. more than what Lenovo can be bothered to do.. but I have different information:

 

"Lenovo APCI-Compliant Virtual Power Controller

 

Provider: Lenovo

Date: 17/2/13 

Version: 9.52.0.776

 

-Driver File Details-

 

Provider: Not available

Version: 6.1.2601.5

 

 

I note again that today there are error messages all over many of the 'yoga 2 13' support pages and re-downloading the file seems impossible.. but I've attempted the update with Lenovos correctly downloaded but broken and incorrect ACPI driver update files many times.

 

 

---EDIT---

 

The Lenovo driver download wepsite page for my laptop has started to work again so I'll download the latest version of the driver and see if there's any difference to the broken one they had up before..

 

---UPDATE---

 

Executed file.. nothing.  Checked Lenovo ACPI in the the device manager.. Same as above.

 

Bad programming by Lenovo.. very bad.  Same that Lenovo doesn't stand up to the product hype.. keys are beginning to fail on the laptop too haha.
