Hi everybody, let me talk about my problem and after this I hope someone could help me.

Since 2 months ago I have a problem with my battery indicator, when it's 100% and I unplug the laptop charger shows 100% for about 1 hour and then begin to reduce the percentage on my battery icon. When the indicator when the indicator shows about 50% my battery die. My laptop is a Lenovo Y4070.
It's not my battery cause the battery is discharged within 4 hours. I tried recalibrate my battery about 10 times, let the battery full charged, and let it die but the problem persist, also I unplug the battery and hold the power button for 30 s. to discharge any remaining charge, after all this steps I found that the Lenovo ACPI-compliant virtual power controller has an issue with Windows 10 and it's not compatible.
I tried to uninstall in the device manager where it's located, right click on it, uninstall and after this disable, then reboot the PC, but after the reboot the Lenovo ACPI-compliant virtual power controller stills on:banghead:
Doesn't matter how many times I try the driver doesn't disappear.

And I just wanna know how uninstall this ****** software from my PC.

P.S.: Sorry from my English cause I'm not American and I still learning your language. I also include a screenshot of my device manager to show where is located.Sin título.jpg
 
Hi alexbartleboom,

When you're uninstalling the driver from Device Manager, have you set it to delete the driver itself as well? To do this, when in Device Manager and "Uninstall" is selected on the "Lenovo ACPI-compliant virtual power controller" you would check the box "Delete the driver software for this device" if it's available. Windows is likely automatically detecting the driver at startup and re-installing it, so by deleting the driver during the uninstallation process, it should stay deleted the next time you restart.

Your English is very good! :)

What are the low and critical battery levels set to?

To edit them, open control panel -> Hardware and Sound -> Power Options -> Change Plan Settings -> Change Advanced Power Settings. Scroll down to battery, and check what the low and critical battery values are set to. For perspective, my low is 7% and critical 5%.

Yes Xer, every time I've tried to uninstall I check on the markbox to delete the driver permanently but it stills every time I turn on the PC, Windows still re-installing the driver but I don't know where I can delete the root from this software to delete it. ss.jpg

Tekno Venus my levels are: low 15% and critical 10 % but my laptop before this always gave me a warning when my battery level reach the 15% but now there is an issue where windows can't read the correctly battery level.

Thank you very much for taking the time to answer me.
 
So if you disable the device (assuming you even have the option) does it also re-enable itself? If you go to Properties for the controller in Device Manager and select "Driver Details", what drivers/paths are listed?
 
Yes, it is correct, no matter if I mark to delete the driver after uninstall it or disable, always re-install and re-enable itself. This is what shows "Driver Details"1.jpg2.jpg
 
I strongly recommend making a restore point before trying this.

Uninstall the driver from Device Manager again and this timedo not check the option to delete the driver. Navigate to C:\Windows\System32\drivers, right-click on AcpiVpc.sys, and select Properties. Select the Security tab, then 'Edit...', highlight SYSTEM and check the Deny boxes for Modify and 'Read & Execute'. Then restart again, and Windows shouldn't be able to re-load the driver.
 
Hi everyone



This driver seems to affect users upgrading to 10 from 8.1 or 7. If disabling the darn thing proves trickier than it's worth, see if a Windows 10 driver is available for your model. I couldn't find a link for your exact model, but that's likely because I'm here in Southern California.... Your area likely has different models available. Lenovo did release a Windows 10 compliant ACPI power driver set for its Y400 series here ... so check on the Lenovo support site for your area, and see if one is available for your model too. The US model has an update dated from February 2, 2016
Advanced Configuration and Power Management Interface (ACPI) Driver for Windows 1 (32-bit, 64-bit) - Notebook - Lenovo Support (US)

I'm thinking you might be able to find a similar, exact-match update for your model too.

Cheers
 
It doesn't work Xer :noidea: here is the screenshot, after this I also tried to delete the AcpiVpc.sys but it doesn't work and the I returned to the "restore point" 3.jpg

I tried that before when I talked with Lenovo assistance but it doesn't work. I'm not the only one with the same problem it is an issue on this PC model.​

You didn't deny the Modify (Modificar) permission, but I'm not sure that it will make much of a difference. If it didn't cause any issues then you don't need to load the restore point, that's just for if something goes wrong. If you want, you can try it again and just check Deny on 'Full Control' (Control total).

Past that, you can try Microsoft's "Show or Hide Updates Troubleshooter". Run wushowhide.diagcab, on the first screen select "advanced" and uncheck "Apply repairs automatically". Once it detects your available updates, choose "Hide Updates", and if your Lenovo software/driver appears there, check the box to hide the update and complete the troubleshooter.

The other very definitive way to do this would be through Group Policy, as you can configure 'Device Installation Restrictions' to prevent installations for the ACPI VPC device ID, but that will require that you have Windows 10 Pro, whereas you likely have the Home edition.
 
Updating my post, I forgot check the modify box as you said tome, but it doesn't work after reboot the "Lenovo ACPI" stills so I tried checking "delete the driver" when I tried to uninstall it, after a reboot the "Lenovo ACPI" stills on the device manager but now on "other devices" so I think it's a good new. I'll using the PC and making reboot to check if the driver re-install itself. Thank you very much for all of you for taking your time to answer me.
 
Hope it works out. Sorry that Lenovo didn't provide a working driver yet. The Microsoft tool to block specific driver updates that Xer pointed to is a nice life-saver for tricky driver problems like this.

I like the new IdeaPad models ... I recommended one to my niece, and she loves it. Hope you are enjoying yours.
