HP ENVY TE-02, reboots randomly when in power save mode.

[Lester22]

System reboots randomly when left unattended in sleep mode. I changed Power Settings, allowing only monitor to sleep after 5 min. It reboots less often, but still reboots. Windows Event Viewer shows critical errors:  The system has rebooted without clearly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly

Event ID:     41               Task Category:      (63)

Keywords:  (70368744177664),(2)

Any suggestions will be greatly appreciated

Chat with HP tech did not help. Thank you

If a computer is in sleep mode, it will only need to restart if a trigger is active
so in general movement of the mouse, keyboard, or network!
if the mouse has an on/off button, turn it off, or remove the batteries
same for the keyboard!
then check in the device manager the network cards, uncheck the options 'allow this device to wake from sleep mode'
the error message, given is not very explicit, because it can happen, just if the computer, was turned off, abnormally!
If you still have problems you will have to do hardware tests

I think I solved the problem.

From the first day I had this computer I had critical error Event 41 in Windows Event Viewer:

1.  After normal shutdown next time I turn on the computer the error was in Event Viewer.
2. When computer was not active for longer time and  power save mode turn off the screen and other functions.

At that time Widows had all default settings – I didn’t change anything yet.

Took me couple weeks to realize, that something is wrong.

After viewing errors in Event Viewer and searching for answers I made some changes.

1.  Normal shutdown should not generate Event 41 error. Control Panel>Power Options>click on left “Choose what the power buttons do”. Then uncheck box: Turn on fast startup (recommended) This helps start your PC faster after shutdown. Restart isn’t affected. (I didn’t have errors on restart only after shutdown and when computer sleeps). After this changes I did Shut Down and when I turned on computer again error 41 was not in Event Viewer.
2. To fix error reporting when computer sleeps, I increased boot ready space to 128MB. I had page file on drive D. (When operating system is on drive C having page file on D improves performance). I also made custom large page file on drive C – my thinking was – may be Windows try to store info about computer sleep in page file and there is no page file on C, therefor information is lost and Windows log error.

My Power Option is now set to turn off only screen after 5 min. Never is set for other components and Best Performance enable.

After this changes for 3 days Windows  did 't report critical error 41.

I won't do it! How i get to my computer if I disable mouse and keyboard? If this is a joke, is not funny.

Sorry, but I don't understand what you are saying.
you say it's fixed but "After this changes for 3 days did now report critical error 41. "  ??
"I won't do it! How i get to my computer is I disable mouse and keyboard? If this is a joke, is not funny."
Who tells you to turn this off?
I just asked you to try the hardware tests to check if there is not a problem!

[Lester22]

Sorry, you advice to disable  only network card from waking up the computer not mouse and keyboard.

Thank you for trying. After 4 days I don't have critical errors in  Event Viewer.

Ok, so it works after what I told you to do, is that right, or not it continues?
indeed, I had just indicated to do a test, by temporarily turning off the keyboard and the mouse, either with a button or by removing the batteries
