December 2019 W10 Update Created two Problems

Currently I have W10 Home Ver 1909, OS build 18363.836. Prior to the Dec 2019 update, two things worked perfectly: I could cause my laptop to enter Sleep using Start > Power > Sleep; and I had used Settings to cause the computer to allow a screensaver upon inactivity but not to "lock" it out to the Login Screen (where the field for my password is displayed) to come on for four hours. (Amount of time is insignificant - could be any amount of time.)

First problem: After the Dec 2019 update, using Start > Power > Sleep causes my external monitors to black, the three LED lights on front show this: left one stays on (as it is supposed to), middle starts blinking, right side goes off. Previous to the update when I used the Sleep command, the middle and right LEDs went OFF. After a minute of this, the monitors come back on and the Log In screen with field for password is there. I.E., the laptop will not go into Sleep via this pathway.

Second problem: After that update, every two minutes of inactivity the Login lock screen comes up with the password field. Doesn't matter what kind of changes I make in Power Settings.

I have been in chat help with MS six times and have even reinstalled W10. Have searched the web far & wide (hours & hours) and tried every suggestion I've found. I have a diary of all the tweaks I've tried if it would be of help.

I'll try anything - not afraid of Registry tweaks/hacks. Yes, I know how to use Restore before fiddling with Registry.

P.S. - all the MS CSRs have used the term "Lock Screen" to describe the screen where the login field appears, but online I see that Lock Screen and Login Screen are two different things. So now I am using Login Screen with an added descriptor in order to be very clear about what appears.

Greetings Ken and thank you for reaching out to me.

1. Every MS chat CSR had me check all the drivers and the BIOS, even when I had just done so. I can say with confidence that they are all the latest and the BIOS has been updated.
2. When I reinstalled W10, that wiped out my past history of W10 update dates. After the reinstall, W automatically then went thru the updates, so all the dates showing since my reinstall are not the dates they came through the first time. (IE the December update) However, having said that and having now to remember this strictly from memory, I believe it was a Tuesday update.
3. My Update history records time only since I reinstalled W10. I reinstalled on 3/27/20 and then there were immediate automatic updates.
Oh no, I had completed this (4 more items!), tried to hit Submit, and the page had timed out.....guh....
4. If I'm looking at my Device Manager page correctly, the only video driver I have is Intel. I will try to get the nVidia driver to install.
5. MS CSRs referred me to the support page and at one point I painstakingly went thru all of them trying to install (I did not understand if there was some way to know which to try and which to ignore). However, that was prior to the W10 Reinstall.
5.a. I will go thru that support page again and try everything.
6. If I'm reading my Device Manager page correctly, I do not have the Toshiba System driver. Will try to download that one.
7. No issues being reported.
8. Yes, BIOS is up-to-date.
9. I will perform the actions and report back.

Thank you SO much. :)

1. Checked BIOS version on my computer vs. the support page. Mine shows: BIOS Version/Date Insyde Corp. 1.40, 4/28/2014. The version & release date on mine are same as what is listed in the support page.
2. I found and installed Toshiba System Driver, but once installed/restart, it does not show under that name. Instead it lists itself as "dynabook Service Control Driver." If I hadn't carefully been watching the procedure, I would not have known that was same as "Toshiba System Driver." After the initial install, it wanted to Update. When I updated, Device Manager found a more up-to-date version and that was the name. So I hope I really do have a Toshiba System Driver.
3. In my Downloads folder, I see that I downloaded the most recent NVidia Display Driver on 3/28/20. But it does not show up in Device Manager. I'm trying to do it again.
3.a. I'm leery of this website timing out again. The Nvidia DD is taking forever to extract. Will report back after it completes.

Thank you.

Greetings. While we were in between threads and in between my work tasks, I did download the Nvidia software, only to have it tell me at the end of a very long process that I don't have the compatible hardware. No big deal - I learn more all the time. And I was glad to have made sure that was not a problem.

I must also remark that the MS CSRs had me use Driver Booster 7 free version to check my drivers. After this, I don't think that thing is accurate. I also went to Device Manager and went through every listed device using "Update Driver." At this point I don't think I trust that command actually finds the true latest driver in every case. So if at any time I should go thru the list of drivers on the Support Link you sent, just say the word. I've done a handful of those but I'm willing to go through every one. I take it that if I do that I need to find the most recently released version (when there is more than one listing for a driver) and download only that one?

Screen Saver is set to "3D Text" and Wait 45 Minutes and no checkmark next to "on resume, display logon screen." Prior to the December 2019 crash, that was performing as set. Since then, my screens don't go to this screensaver - they just go to black and any actions (mouse wiggle, hit a key), the log-on screen comes on with the field for my password. Plus the problem of the computer locking out every few minutes.

I have always had my two external monitors connected, plus a wireless mouse & keyboard, plus the setting for "when I close the lid do nothing" since I need to have the laptop closed while working so I can see my two externals.

I will be happy to test by disconnecting monitors.

I'll try to get in some work on this tomorrow (5/16/20) and will report back.

And should I zero in on the driver for the Toshiba and make sure it is installed?

Hello. After I hit Post last evening, I was looking at drivers in Device Manager for the 2 external monitors and the Toshiba monitor. The 2 externals are Dell (on that site now seeing if they have latest drivers for these). But curiously, the 3rd monitor listed is "Generic PnP Monitor." That certainly is not the Toshiba! I found this site about "generic PnP problems": Fix Generic PnP Monitor problem on Windows 10 (Solved).

Also possibly related to this is the listing in DM for Display Adapter Intel Graphics. If I understand the Dynabook site, the latest one is Intel Display Driver, Posted Date: 2016-10-05 | Version: 10.18.10.4252 | Size: 126.59M. The info listed in my DM is version 10.18.10.5129 Could it be that Driver Booster 7 found this latter number and it is causing a problem? If so, shall I remove it and install from the Dynabook site?

Okay, on to the jobs of disconnecting monitors, making sure the 2 externals have correct drivers, and what the heck, might as well install Intel Graphics Display Adapter driver from Dynabook.

External monitors disconnected right now. I also "rolled back" the Intel Display Driver to the latest version listed in Dynabook rather than the mystery one listed in my DM. Also did some digging about drivers for the two external Dell monitors. Apparently external monitors are considered "stand alone" and do not need to have driver updates, according to all the sites I found discussing Dell stand alone monitors. (Please advise if I should do further with these two.)

In a few minutes I will sit around to see if the laptop monitor locks out to the Log-On screen after some minutes of inactivity. Will also test the ability of the laptop to enter Sleep mode using Start > Power > Sleep, to see if anything has changed, and report back.

Cheers,

GUH. No joy. Screen goes to Log-On after 2 mintues and no Sleep. I seem to have done everything so far - but if you see something I've missed, please do point it out. I gone through every driver in the Dynabook page and installed the ones I have not done so far. I'm willing to try that.
