Windows 10: Windows Locks/ Enters Standby After 5 Minutes

I don't know where else to turn... I hope someone here can help.There's a few computers in the company I work for that have started locking themselves after 5 minutes.This is what we have tried so far:- Restore default power settings.- Create a different power plan with all options set to "never".- Changed local security policy > security options > machine inactivity limit = 0, or whatever other number- Checked all of our mdm policies -> none are relevant - Even setting a random screensaver to 30 minutes doesn't work. Screensaver comes up after 5 minutes... and setting is reset to 5 m

:)

 

why the 5 minutes break?

Hi all, I don’t know if this is a known matter and if there’s a solution.

Normal procedure for locking keypad and unlocking:

• I set "Security keyguard" and "Automatic keyguard" On to lock the phone,
• I go to homescreen and wait 1 minute for it to be locked,
• I press Unlock key (here it’s menu key) and * key (star key) then enter correct Security code 12345.
• Phone is Unlocked.

Nothing’s easy then this. But what if I type wrong codes for a few times just as a test:

• I set "Security keyguard" and "Automatic keyguard" On to lock the phone,
• I go to homescreen and wait 1 minute for it to lock,
• I press unlock key and * key and enter random wrong codes for a few times (NOT 12345),
• phone is still Locked due to wrong Security codes with message “Code error”. Good!
• Now I press Unlock key and *key and this time I enter correct Security code 12345 then ok.
• But Phone is still Locked with message “Code error”!!!! I retry entering correct Security code 12345 again with no luck.
• what do I do? I waited 5 minutes and retried entering Security code 12345 again and OMG this time it’s Unlocked. Good.
• to make sure of this, I repeated steps 1 to 7 and same matter.

Why does the phone lock itself completely on me for 5 minutes that's after a few Erroneous security code test attempts (maybe 3 or 5) even if after this I directly enter correct Code 12345 but it's still locked??

Is there any extra Security code in this case? how to let the phone accept the correct code before 5 minutes?

 

my son laptiop wifi disconnect after 5 minutes

• If you have an identical laptop try comparing the wifi and security settings of the one that does not disconnect with the one that does. If you find any differences change the settings of the one that does not work to the one that does.

• If you do not have an identical laptop see this post and the three replies for possible solutions: Wifi disconnects every 5 minutes.

@Samuria : If you have any suggestions please reply.
