The touchpad and keyboard of my laptop stops responding after waking up from sleep mode.
This symptom took place after the last windows update somewhere early november,
After a cold startup everything functions normally. without any problems.
When putting the laptop in sleep mode, either via powerbutton or lid, you can still wake the laptop with the keyboard or touchpad, after that everything stops responding.
Mousepointer isn't visible.
bios is updated, mousedriver is reinstalled, did the battery out-60secs powerdown thingy, reinstall to factory settings,tinkered with wakeupsettings keyboard-touchpad, none of it made any difference.
I cant imagine that HP or their drivers is to blame, but then again, I expect to find more quality assistance here then at microsoft. 🙂
Is this a more common problem, and what´s to do about ?

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers.

I see from your post that you're having issues with the keyboard and mouse not working after waking the computer from sleep after the recent windows update.

In this scenario, let's try these steps here:
1. Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. In Device Manager, locate the keyboard, and then double-click the device name.
3. Click the Power Management tab, and then Select the option "Allow this device to wake the computer" checkbox.
4. Click Ok.
5. Locate the touchpad and Repeat step 2 and 3.
Also, update the drivers of both Keyboard and the touchpad using this link.
Alternatively, I would suggest here is to Run Windows Updates troubleshooter -

Now try to perform Windows Updates -
1) In the search box, type and open Windows Updates.

I've followed all above steps,
The touchpad driver rollback gave me a "code 10" msg and fails to function completely on the HP driver.
Funny thin i noticed.....USB also refuses to work after waking up, as an external mouse wouldnt function also.
Unfortunately the rest of the steps wouldnt work also.
I've updated again to the newest Synaptics driver, so everything works in cold start again.

In the thread I opened (see link in my post of 18 July 2019) I was promised that HP Support would contact me about this issue. Since then I've had about ten private messages all promising that someone will contact me, but nothing has happened. As that thread has been closed for unknown reasons , I'm reporting the situation here.

I think I have finally found a work-around/solution. My laptop (Elitebook 8540p) running Windows 10 goes to sleep after 10 minutes or so without activity (or when I close the lid). When it wakes up, the touch-pad is generally inoperative. This has been going on for some time and I thought it was a driver problem. I can uninstall the driver and restart and this used to "fix" the problem. Today, this didn't work! I have read just about every article on the net regarding this.
My solution was to force the laptop to sleep (Fn)<F3> (the function key with the moon). Once the laptop has gone to sleep, press the power button and the laptop wakes up and, hey presto, the touch-pad is working again.
This suggests Windows is not talking to the laptop's bios.
The gurus at HP might need to look into this.
