Restart loop HP Laptop

HP Recommended
HP EliteBook 840 G5
Microsoft Windows 10 (64-bit)

Hi,

My laptop stuck in a restart loop.

- When turn on my hp laptop, It is opening normally. But when it opened, randomly within a 0-5 min time range it suddenly restarting it self.  No blue screen no warning just sudden restart.

- Most of the time restarts happening again and again. It is hard to explain actually. The first sudden restart happening time may vary 0 to 5 min range. But after first sudden restart happen. It goes a restart loop. My laptop shows a recovery options after a while. But there is no way to detect the problem or solve the problem from these help screens. 

- Also these restart loops happens if my laptop turn off at least 4 hours. For example if I close my computer now and open it again it will not happen. There should be closed for a while. 

- Another thing is most of the sudden restarts happens with the first hit to the keyboard or mouse. What I mean is It goes restart as soon as I hit the keyboard. But this is only true for first sudden restart case of the loop of restarts.

But eventually it stops restarting and turns to normal.

 

Like I said it is almost impossible to define the case in a accurate way. Because the problem happens randomly and behave randomly. But I want to hear the questions to define the problem better. 

 

Thanks and Regards,

-Ibrahim

Hi
PLEASE POST ANY RESULTS.
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat; Re-Connect the AC adapter.

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
AND/OR
HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly.

Hi Lil,

 

Thank you for your answer. I did what you purpose. And also I did the extended testing (4 h- 5 h). The result is passed for all sections. But the problem is still  occurring.

From 2016 onwards there is a possible recovery option via the cloud...
HP Consumer PCs - Using the HP Cloud Recovery Tool (Windows 7 & 10)
https://support.hp.com/us-en/document/c06162205
OR
This First part only works when a valid Recovery Partition is enabled.
If it displays an error message then move onto the Second part,
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.
Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.
WARNING - ONE WAY ONLY, WIPES ALL DATA - NON-RECOVERABLE
Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.
W8 Repair.pngRecovery Reinstall.png
Second Part:-
This may require another PC. Find and Download your .iso from…

https://www.microsoft.com/en-us/software-download/windows10
Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

Even though it has NO actual HP software/drivers included, you may be able to
XCOPY the C:\Users\* area onto a ‘large’ USB stick, via the Command Prompt.

You’ll need to try various drive letters; D:..-..Z: until it’s matched - could be G; mine’s S:

C:\>XCOPY C:\Users\* S:\ /e /i /h (then files like those 3 listed below get copied over)

C:\Users\desktop.ini
C:\Users\All Users\agent.1509128044.bdinstall.bin
C:\Users\All Users\HP Deskjet 2540 series\Help\flash\zoom.swf

Then you can try System Recovery Options / Advanced Options shown in the screenshots.

NB:- W7 Try running a Startup Repair more than once for a full fix.
NB: - W10 Begin with the Automatic Repair, then Startup Settings etc.

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD

If the above FAILS then please try:-
