Lenovo Ideapad 100S-11IBY problems after installing Windows 10 Anniversary Update (aka version 1607)

Ron Hewett asked on

Yesterday my Lenovo Ideapad 100S-11IBY (a 11.6" screen low spec laptop) installed the Windows 10 Anniversary Update (aka Windows 10 Version 1607). Yesterday was the first day as far as I know that the update was available to install on the Ideapad (even though the update was first released by Microsoft 2 months ago). The Ideapad now has multiple problems and is unusable.

 

1. The keyboard (yes, the built in laptop keyboard) does not work. None of the keys (letters, numbers, 'actions' like backspace) work at all. If I plug in a USB wireless keyboard, it works just fine. So maybe there is a problem with the device driver for the built in keyboard with the Anniversary Update. The keyboard worked just fine before Windows Update installed the Anniversary Update.

 

2. The trackpad does not work. If I plug in a USB wireless mouse, it works just fine. So maybe there is a problem with the device driver for the trackpad with the Anniversary Update. The trackpad worked just fine before Windows Update installed the Anniversary Update.

 

3. The 32GB Kingston microSD card plugged in to the microSD port is not recognised by File Explorer. If I plug the 32GB Kingston microSD card into a USB microSD card reader, and plug the card reader in to a USB port on the Ideapad, the microSD storage is recognised in File Explorer, so the microSD card itself is fine. So maybe there is a problem with the device driver for the microSD port with the Anniversary Update. The microSD port worked just fine and the microSD card was recognised in File Explorer before Windows Update installed the Anniversary Update.

 

4. There is no audio, Windows now says no audio hardware is installed. So maybe there is a problem with the device drivers for the builtin microphone and builtin speaker with the Anniversary Update. They worked just fine before Windows Update installed the Anniversary Update.

 

I have tried doing a RESET but unfortunately although the reset worked, it reset to Windows 10 Version 1607 (aka Anniversary Update) not an earlier version of Windows 10 and I still have all the above problems. As far as I can see, Windows Settings now say there is no Update History and no previous version of Windows, so I can't use any recovery method with what is available on the PC itself to go to an earlier version of Windows.

 

Please can someone advise how I reset my PC (and where I can get the appropriate Windows 10 32bit ISO file or whatever) to Windows 10 Version 1511 (that is, prior to Anniversary Update) ?

 

Or, alternatively, are device drivers valid for Windows 10 Version 1607 for builtin keyboard, trackpad, microSD port, microphone and speaker available somewhere ? I don't see them on the Lenovo support website.

Sorry for the delay, I've been away and as the device was unusable, I didn't take it with me.

1. Windows Update Troubleshooter didn't help.

2. I looked at the driver update article, and then went to the Lenovo website. In 'Drivers and Software' for this device, there was a 'Chipset' driver called 'Intel Platform Driver for Windows 10 (32 bit) - Ideapad 100S-11IBY'. I downloaded and installed this, then after being prompted, restarted the device. I am happy to report that

(a) the keyboard now works

(b) the trackpad now works

(c) the microSD card is now recognised by File Explorer

(d) the audio now works
