    Auto Locking and Shutting Down

    Hi Guys

    I've got a very common problem with my fresh Win 10 Pro 32bit install. After an unspecified amount of time (all different lengths), my laptop keeps auto locking, then shutting down, no amount of button presses stops this process, i havde to wait fir it to conpletely shut down, then press the startr button and it resumes as if nothing has happened, all powewr settings are set as 'never', power buttons, lid closing and everything else are set as 'do nothing', i've followed the instructions from Google about enabling the 'do not display lock screen' in gpedit section, i've also read loads of pages on this site about it, but to no avail, my laptop is a Dell E6420, i5, 4GB RAM. This never happens on my other general use laptop, this Dell machine is solely for my Jaguar diagnosis software, so doesn't have any other software installed, i'm trying to download all the updates for the software, as it's freshly installed, there's loads of uodates to download and install, but it's taking over twice as long due to all these lock/shut downs, it should've completed overnigth, but shut down at some point.

    Any help please guys & girls?

    If your CPU is overheating due to dust on the heat sink (very common on old laptops) it will shutdown to protect itself.
    Download Open Hardware Monitor and extract to a folder (I have extracted mine to C:\Program Files (x86)\HardwareMonitor.).
    Run openhardwaremonitor.exe and on the options set to start with windows.
    You can configure what to see on the gadget and on the try, Very good
    CPU should never work above 80C.

    I suggest that you look in Event viewer to see what happens at the time of these unexpected shutdowns.

    In case you are not familiar enough with Event viewer -
    1 Unzip the attachment Power - Starts,
    2 Open Event viewer [%windir%\system32\eventvwr.msc]
    3 On the right-hand side, click on Import custom view. Call it whatever you want when it prompts you. I call mine Power - Starts, shutdowns
    4 On the left-hand side, click on Custom views to expand the list and look at Power - Starts, shutdowns
    5 Each entry has a time.
    6 'Good' entries will be EventID 1074 and will be shown as Information entries
    7 'Bad' entries will be EventID 6008 and will be shown as Error entries with a red icon.

    If your surprising shutdowns are consistently shown at the appropriate times as EventID 6008 then this will confirm that Windows is not shutting down for legitimate reasons.
    - I'd say that temperature monitoring, as suggested by Megahertz, would be an appropriate response.
    - Do also try to note what you are doing at the time of the surprising shutdowns in the hope that a pattern emerges.

    Best of luck,
