HP Envy x360 Windows 11 random crashes and reboots when running on battery power

[MayJ28]

Hi,

I bought my HP Envy 360 in November.  It came with Windows 11 pre-installed.  I have noticed that it randomly crashes or reboots when it is running on battery power.  This does not happen when I have the charging cable connected.

I have received the blue screen of death and the a variety of error codes.  Unfortunately it flashes up so quickly, I haven't managed to catch all of them.  

The one that I did manage to quickly take a picture of was WHEA_UNCORRECTABLE_ERROR but I have had others.  A numerical code containing several 0's and ending in 21a (I think).  I had something about a CRITICAL_PROCESS too.  

Sometimes I don't get any error message, it just reboots.  It happens at random times, regardless of whether I'm using the computer or not.  The battery is fully charged and there is no sudden drop in the level.  There is no warning that this is going to happen.

I have tried repairing Windows by returning it to its default state and I have run the HP Hardware diagnostic tests.  I have run the chkdsk function and checked my drivers.  They are all up to date and I have no conflicts.

I saw somewhere that you can generate a log file to capture these errors and tried to do this but when I try to access the Memory Dump file, it tells me that I don't have permissions?  I have download the Windows utility to enable me to read the log but that reports the same thing.

Is there any way to capture these errors in a log so that I can at least try to pin down what is causing this?

I really don't want to have to purchase Windows 10 in order to use my laptop and it is important that I use it without it always being connected to the power.

Thanks for your time!

hey

majority of WHEA uncorrectable errors are caused by hardware failure, resolving this error usually entails identifying and replacing the faulty component or component set.

you need to run hp hardware Extensive Test 

to check if hardware failed

HP provides diagnostic software for testing hardware components on your computer and confirm hardware failures.

if  all hardware test pass

please update bios and drivers

Hi Charli, 

Thanks for coming back to me!  

I've run the HP extensive hardware test a couple of times and it has passed. I have also checked my system using the HP online tools and it says that its up to date. 

I know it's awfully vague and difficult to pin down.  How can I tell if my BIOS is up to date?  

It would seem to be power related as it only happens when it's on battery?

Can I also ask how long the standard manufacturer's warranty is?

Thanks 🙂
