Lenovo ideapad 100S-11IBY touchpad disables when on battery

2017-10-20, 15:54 PM

Hello,
after last Windows update my touchpad gets disabled when laptop is on battery, when it's plugged in and charging everything works well. I can enable touchpad with shortcut on F6 key, but after few seconds of not using the touchpad, it disables by itself. I also noticed that I can enable touchpad by clicking the physical left or right click below it, but not by tapping the touchpad. Also, I think it has something to do with Power Management, but when I go to Manage->Device Manager->Mice and pointing devices->HID-compliant mouse and go to Properties, I don't have the Power Management tab there. Drivers are up to date, and there are no mouse drivers on Lenovo support page.

 

I ran out off ideas, any help is appreciated. Thank you in advance.

Solved! See the solution

I also have the same problem after win 10 fall update.

 

Symptom:

ONLY on battery, internal touchpad and any external mouse i connect, gets "disabled" after about two seconds of inactivity. Clicking any touchpad key, or any mouse key (even the scroller) re-activates it - only to power down again if its not moving for two seconds.

 

VERY ANNOYING 

 

No problems on AC power.

 

Tried all power management options (actually there are none), tried setting USB controller and ports (on device manager) not to power down to save energy, tried disabling selective USB suspend from CMD->powercfg.

 

None helped.

 

Windows simply powers down mice and touchpad after two seconds (on battery only) - any key re-activates them.

 

PLEASE HELP

I can confirm the same issue here. I have tried the above steps and also uninstalling and re-installing the driver, updating the BIOS, and re-installing the chipset drivers to no avail. Any help would be nice!

Same issue here. Complete reinstall gave same result. Forcing use of Synaptics latest drivers was still the same. Adding registry entries to disable USB selective suspend and PCI Link State Power Management gave no improvement. This, combined with everything being ok with Windows 10 update 1703, makes me suspect Microsoft's update 1709 is the problem rather than anything inherently wrong with Synaptics drivers. I have reported it as a problem to Microsoft and suggest you do the same.

"ideapad 100S-11IBY" is listed on Lenovo's 'tested for Windows 10 Fall Creators Update' page here: https://support.lenovo.com/us/en/solutions/ht505322

Therefore I believe they have some duty to provide support, as I checked that list for compatibility prior to installing.

My 100S 11IBY model 80QN does the same thing. Can not run without power cord. Must be a LEMON issue with this model
