HP Laptop shuts down at exactly 30 mins

I have an HP laptop that is running Windows 10.   Not matter if in Safe Mode or production mode, the computer shuts down (again exactly at 30 mins.    The computer was 8.1 upgraded to Win 10.   I checked for Malware, Just a few PUP's that were quarantined.   It has 8 GB Ram.  Any ideas?   It does have Norton Anti-virus.

idle 30 minutes or active it shuts down after 30 minutes?

Commented:
Idle 30 minutes would suggest an Power Management setting, for when the laptop is plugged in or using its battery. Maybe change that to stand by, or turn off the screen, or increase the time when it does shut itself down when on battery power.

I think it must be a timer or something like that, try to set the BIOS values to default and try again,
It can also be a Motherboard Problem.

Check also BIOS settings Power Management.

Check HP website for latest BIOS Update , if available Upgrade it and retest.

If it is possible, remove the CMOS battery for a few minutes and reset BIOS,

If above solutions didn't help then it is a Faulty Motherboard.

Idle or while typing, moving mouse, no matter what it shuts down at 30 mins.  I don't believe it is a short in the motherboard, or bad RAM because whether I start it cold or restarted it after it shut down, it shuts down at 30 mins.   I will try removing and replacing the CMOS battery

Can you boot from a Live Linux CD such as Ubuntu https://help.ubuntu.com/community/LiveCD ?

If it boots from that and runs for more than 30 minutes then it is probably a Windows software problem.

However unsure if your laptop would permit booting from a CD, you'd have to check BIOS settings and see if that was permitted.

If there is any power management feature in BIOS, Disable it,
Try to stay for 30 Minutes in BIOS, if the PC Shutdown then it's not a Windows problem.
CERTIFIED EXPERT

Commented:
I would think it very unusual for a hardware problem to occur with such regularity.  If it is temperature-related, for example, it might consistently fail after about 30 minutes, but the time would be inconsistent and would happen sooner after a reboot or if the ambient air is warmer.

Booting a Linux disk, as suggested above, would be a good test of whether it is an issue with the hardware or not.

Have you tried Windows in Safe Mode?  Whether or not it shuts down there would be a good test.

Is the shut down a proper shut down where it closes everything as if you requested it to shut down or is it abrupt as if all power were removed?

Commented:
In Safe Mode it shuts down at thirty minutes.  I booted into BIOS and it shut down at 30 minutes.    I unplugged the CMOS battery for about 2 minutes.   I reassembled laptop and rebooted and it shut down at 30 minutes.   It doesn't shut down normally it shuts down like it loses all power.

other tests  you can do : hook up another disk with another OS on it - Linux, ubuntu, or windows, to Ensure it's not an OS problem
you can run it also -as suggested from a live CD

did it also heappen when it was on win8.1 ?

Remove battery and try run computer only on Power Cord for 30 minutes.
If laptop will not shuts down, then this will point to battery or charging system.

McKnife, where in event logs do I look I went to Event logs >Windows Logs> System and it showed nothing at the shutdown 20 mins ago.

Tom Cieslik I ran it on just AC, no battery and it shut down at 30 mins.  

Nobus, no it didn't shut down in 8.1, upgraded to 10 about a year ago and this started about 6 -7 months ago.    I will try Ubuntu.

So if laptop , without battery, stay in BIOS window and is hard restarting/shooting down itself it mean there is an electronic issue on your motherboard, or laptop is overheating itself.
If laptops is not hot, then probably you must replace or repair motherboard

exactly thirty minutes no matter what you do, what is the message that is displayed if any? Event log application shoukd indicate an entry on shutdown and on bootup.
Is this an ad based system? If hardware issues eliminated, this sounds as an update being installed then a system

For laptop get the system monitor for heat, etc. and see if thermal .....

Unfortunately, if you tolerated this situation for almost seven months means that you are definitely outside the HP warranty which is usually one year unless you bought extended warranty.

"Event logs >Windows Logs> System and it showed nothing at the shutdown 20 mins ago." - then it was no shutdown but a crash/black out. Be precise about what happens, please, how does your "shutdown" look like?

Sorry McKnfe.  It is a instant power loss,no warning no error no freeze, screen goes black and all lights go out immediately.   Just like a black out.

when it was upgraded to win 10 - was there some hardware change, like more Ram, or disk?

Commented:
Nobus, no there was no upgrade to any software, just the windows 8.1 upgrade to Windows 10.   I have since formatted the partition that held the upgrade and tried to install from an OEM DVD of Windiws 10, but it still shuts down at 30 mins

Commented:
Just to try, I replaced the hard drive with a new drive.   I pushed start button and the HP splash screen would not even come up.   There was just an error message saying no boot device was found.   Why wouldn't the HP splash screen come up first before checking for boot device?

Boot from the LInux Live CD as I suggested earlier.  If it does the same shutdown after 30 minutes then, yes, I'd accept it as a hardware problem.  As it is now it looks extremely like hardware but I'd like to try booting from another medium rather than a hard disk.

Oh, and try the LIve CD without the hard disk connected.

Also try booting with only 4 Gb of RAM.

Ok  If it is hard ware, what makes it shutdown at exactly 30 mins?   Is there  something that keeps time on the board (Other than the CMOS battrery)?   I would think that if it  were heat related it would be random, loss of power, or however you want to term it (I should not use shutdown term, my mistake, because it just go completely off immediately without warning)  rather than at exactly 30 mins.   You are the experts, I am not doubting what you are saying, I just want to understand what part of board would time out like this.

Based on your description it seems the power portiion heats up breaks the circuit since it occurs on the same schedule whether on battery or ac power.
Have you tried removing the battery and running on ac/external power only?

The power cuttoff might be limited to the power component/circuits.

If the Mainboard doesn't support CPU clock/speed or has a faulty ROM / Chip controller can cause this to happen.

Also, it is rare for a normal user to change CMOS battery of a notebook. Do you upgrade the CPU / RAM at the same time before you upgrade to Windows 10?

Once it shuts down measure its temperature. Or check if in cold room it shuts down the same way.

30 minutes auto shutdown without warning which is caused by restrictions imposed by Intel on CPU upgrade.

There is no indication that the user ever upgraded the laptop's CPU prior to this issue. The only change according to the asker is the OS upgrade to windows 10.

"There is no indication that the user ever upgraded the laptop's CPU prior to this issue."
You are absolutely correct, but this wouldn't be the first time that such an important fact was left out on EE!

Given that the shutdown happens after the same duration regardless of temperature or whether in the BIOS or Windows, this Intel "feature" sounds very suspect.

Let's hope the OP comments on whether or not the CPU was changed.

You are not alone and the problem is not related to Windows 10 upgrade.

The motherboard has gone mad and it wants to cut off power output on exactly 30 minutes.

"Product Name: hp pavilion g6
Operating System: Microsoft Windows 8 (64-bit)
Reproducible every exact 30 Min power off
- no Warnings, no Errors, no memory-dump
- no Bluescreens, no beeps
It's a HP Pavilion g6 Laptop with intel i5-3230M CPU and Intel HM76 Express Chipset, Rev. 4.

Doesn't matter: temperature, battery and/or power supply, programs, OS, even running in BIOS or startup System Diagnostics test will power off exactly every 30 min.

If you press power button to go into standby mode and then reactivate system from standby you get another 30 min
until the next crash (or manual standby)."
