Keyboard/touch pad doesn't work after laptop wakes up from sleep

[Nakaima]

I am experiencing some issues with my laptop: when it goes into sleep mode (or hibernate) it's impossible for me to log back in, because both the touch pad and keyboard will not work. If the battery dies on its own, and I have to plug in and reboot, same issue will happen - so I have to reboot twice in order to be able to log in past the security screen.

I have suspended sleep mode for now and only have the screen turn off after a few minutes, which brings some other issues. Often, the screen will light back up after I touch either mouse or touch pad/keyboard, but no image shows up (it's black but lit at the same time - if it makes any sense)... So again, I have to reboot in order to be able to log back in. Both issues are getting really annoying, as the computer can't ever go to sleep (no power savings at all, plus who knows what that does to hardware over time) and having it unplugged means the battery is just depleating pretty fast.

At this point, I have tried pretty much everything I've found online, with no results whatsoever.

- switching power options, making sure keyboard/touch pad can wake computer from sleep mode

- updates of all kinds: BIOS, hardware, software, windows, etc.

- removing and reinstalling drivers...

I have done the latest WIndowns and BIOS update, with no success at all... And I've also used the virtual assistant and tried everything it told me to do, again with no success. Any other suggestions as to what I'm missing would be appreciated.

Thanks!!

@Nakaima,

Thank you for being a part of the Hp support forums. A good day to you. I will be delighted to assist you here and have reviewed the post.

• Did this occur after a software or windows update?
• Was there a power outage or surge before this happened?

It looks like a hardware issue. Let's try these steps:

• Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.
• Check the box that states delete the software for this device.
• Then restart the computer and update the chipset and graphics drivers from this link: http://hp.com/drivers Select the country and type the product# of the unit. Then follow the onscreen instructions.

Then run all HP support assistant updates.

• Also from this link: https://support.hp.com/in-en/document/c04752217
• (HP Notebook PCs - Managing Power Options (Windows 10) delete the existing power plan and select the default power plan in WIndows. then check if the issue gets resolved.
• Also, perform all other relevant steps from the document. If the issue continues,'

Then in device manager perform these steps for both the keyboard and the touchpad:

• Right-click on start>click on devicemanager>Expand keyboards>Then Right-click on the keyboard drivers and click on properties. 
• Then click on power management. then uncheck the box that states "Allow the computer to turn off this device to save power"
• Also, check the box that states"Allow this device to wake the computer"

• Right-click on start>click on device manager>Mice and other pointing devices>Then Right-click on Synaptics drivers and left-click click on properties. 
• Then click on power management. then uncheck the box that states "Allow the computer to turn off this device to save power"
• Also, check the box that states"Allow this device to wake the computer"

Now, this should resolve the issue. Disable Hybrid sleep also.

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
