Hi guys. My laptop is running Windows 11 and early this morning around 5am central time it crashed. It went black screen and completely restarted, no error message or anything, not even the normal blue crash screen (BSOD). I checked event viewer, and it stated that it was a Kernel-Power as source, Event ID 41, with Task Category 63. It says "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." This is the first time that this crash happened on my current laptop and I am wondering if there is a way to find the source of the crash? This happened several times on my previous laptop, and I am concerned since this is now happening on my new laptop. Is this kind of crash well known, and/or common? Is there anything I can do to keep it from happening in future? It would really suck if happened again during a long game session or something. Thoughts and help appreciated 🙂

Windows creates that event after it discovers the previous shutdown wasn't expected. Its not the cause, its a reaction. If anything, that can mean windows doesn't know why it crashed and it wasn't caused by software.
Does the laptop have any software installed from the maker, that you could use to run tests.
Maybe if Omega put his laptop name/model in here, we wouldn't ask each time

My laptop is a Lenovo Legion 5 Pro, 16ADR10. Product number: 83LT000MUS.
Great specs!
Try and manually reinstall your chipset driver. Source them from here;
installing the driver in an elevated command, i.e, Right click installer>Run as Administrator.
Side note, since you have an HX SKU for your mobile processor, you ight want to consider undervolting the CPU and GPU and see if that helps alleviate your issue. It will reduce the heat dumped by your laptop, mind you.

Thanks for the help and info! Is it safe to reinstall chipset driver? Also, what does undervolting the CPU and GPU do exactly? Is doing that safe and also how do I go about doing it? Would undervolting have an impact on gaming performance? Further thoughts and help appreciated 🙂

Did you notice that the two programs listed here are just Adrenaline drivers, and not the actual chipset drivers. IE, they are for the igpu
I don't know how he would find the chipset driver
I don't know about undervolting so I let @Lutfij fill you in there.
undervolting would at least let it run cooler, and maybe faster... as I said, haven't done it so no idea.

Right, so I went looking again;
is for chipset. The one I'd provided prior was for the GPU part of the processor.
You could conversely look up all drivers from the URL that @Colif 's included.
what does undervolting the CPU and GPU do exactly?
Streamlines the power fed to your device/component in which case it would be the CPU and iGPU, resulting in less heat dumped resulting in a cooler laptop. If you're dealing with battery power, then you reduce battery drain.

according to a search, the Motherboard Devices (Backplanes, core chipset, onboard video, PCIe switches) area of the Lenovo site should have chipset drivers, but of the 3 there now
So no chipset drivers there... which seems odd to me.
but lutfis link is the one you want... or should be.
to uninstall current ones, just use the Apps menu in Windows settings, it should be listed as AMD Chipset Drivers
- AMD HIP SDK - is essentially CUDA - not needed
- AMD Serial IO - mostly for input/output peripherals, trackpad etc
- Sunia SPB Peripheral (T con) colour Management - display driver

Something else to consider is that you said this was happening on your old laptop as well. To me, this means you have a power problem that is screwing up your internals. Is the laptop plugged into a surge protector? If so, how old is it? Surge protectors only protect against one surge, and then they have to be replaced (they also protect from a lot of other things that can wear them down over time). If I were you, I'd invest in a good UPS. Even if that doesn't turn out to be the problem here, just about everyone should have a good UPS.
If your processors lose power for even a fraction of a second, it will cause what you are describing, and the fact that you have a battery, presumably, means that there's a problem somewhere between the battery and the processors. It might not be a serious problem now, but if you keep feeding it junk electricity it will eventually be a major problem.
Here's a good question. Have you ever had a laptop that just periodically stopped charging? Then you probably fiddle with the charger pack and the cord and suddenly it starts charging again? That's a sign that you have a power source problem, as in from the wall outlet. Well made laptops will briefly stop accepting power if it is inconsistent enough. That could also mean you need an electrician, by the way. Not necessarily, but if you live in an area where the power should be stable unless something like a storm is happening, then it's something to think about.
Just helping to cover the bases...

Thank you so much for the help and info! Both my previous laptop, and current one, are/were plugged directly into wall outlet and not into an UPS or surge protector power strip. I do have a surge power strip near where I use laptop, but the power strip is also plugged into same wall outlets. Do you think I will be ok plugging laptop into that power strip, even though it is same wall outlet that laptop is usually plugged into? The wall outlet actually has 2 outlets in it. I plug my laptop into top outlet, and power strip in bottom one. The power strip is little less than a year old I think Further thoughts and help appreciated 🙂

That would protect you from surges, but if you want stable power going to the laptop, you need the UPS or a voltage regulator. Only rarely do surge protectors include a power regulator, and usually at that point they are just called voltage regulators.
Poking around the forum here, I noticed that you mention you added a 4Tb SSD. I took a look at the spec sheet for your machine here:
Which says it only supports Max 1Tb drives. That's not saying you couldn't stick a bigger drive in there, but I kind of wonder if you're overdrawing on your power budget with the larger SSD. I'm personally running a 2Tb in my Legion and ran it in my previous Thinkpad P1 Gen 4 without issue, but it might be worth removing that drive and running without it to see if your power issues continue. You also mention you had that in that previous laptop and had the same issue; I wonder if it's either not supported or if it's a cheaper brand of drive that is perhaps not well engineered and causing your issues. That is worth investigating before you potentially damage your machine.

Hey again, I am using the power cord and power brick that came with laptop. I am thinking about getting another power cord though, as the cord I currently have isin't really long. I am looking at this 2-pack on Amazon: https://www.amazon.com/dp/B0153T1O3...MDW06L7B5&ref_=list_c_wl_lv_ov_lig_dp_it&th=1
Should I replace the power cord? I saw you mention that my SSDs might be the problem? My laptop has 2x 4TB SSDs. Is there a way to check power draw from SSDs and see what my limit is?
Further thoughts and help appreciated 🙂

I would honestly be skeptical that the power draw in particular is the issue and there's something else going on with those SSDs. If it were my computer, I would probably throw in a 1Tb SSD, install Windows and a game or two, then use it like that for a week or whatever it usually takes for it to have this crash. If the crash doesn't happen, then you've got a culprit.
What are the brands and models of your SSD's?

Hey again. One of the SSDs is Crucial Brand, other not sure. I know the newer of the 2 is Crucial brand, but the other was installed/purchased early on with my previous laptop. Both are M2 2280 form factor. I looked at that spec sheet, and the max capacity had a little "1" next to it. I read below that and the "1" said the following:
- 1. The storage capacity supported is based on the test results with current Lenovo® storage offerings.

Hi again guys, it happened again just now: Complete laptop crash with no error message, and again it was Kernel-power. I was browsing internet when it happened. Laptop just went completely black screen, no error message or BSOD, and just restarted to Legion logo. I am getting really worried about this and really hope it is not due to my SSDs. I still have manufacturer warranty on it and also have warranty through Best Buy Geek Squad. What do you guys suggest I do? If it matters any, I am at my parents' condo and have laptop plugged directly into wall outlet and not into a surge protector strip. Help GREATLY appreciated 🙂
Again, the one constant here are your SSDs from your old laptop and now this one. Without swapping the SSD, you could run an instance of Linux off a USB stick, which will be running out of RAM. This isn't foolproof, given that maybe your issue is with Windows and Linux would solve the issue.
If this were my computer, I would take out both disks, set them aside and put in a 1Tb SSD, then install Windows. Use it like that for a week or more and see if the issue continues. Alternatively, update Chipset drivers if that exists (you should be able to use Lenovo Vantage to check for drivers). In fact, update all drivers that exist.
Further, I asked Copilot about this issue and this is what it had to say:
Examples:
Yeah, so straight-up, I'd update the drivers and see what happens. But more than likely I'd try the smaller SSD and see if the problem disappears. Again you mention in a previous thread that you had this issue on another PC with the same SSD. That seems to suggest a common cause.

🧩 Why a 4TB NVMe
1.
Windows’ built‑in NVMe driver has been shown to cause:- System deadlocks
- Kernel‑power crashes
- WHEA PCIe errors
- Total system freezes under sustained I/O
2.
Large‑capacity drives (2TB–4TB) often use:- Newer controllers
- More aggressive power‑saving states
- More complex FTL (flash translation layer) mappings
Examples:
- Samsung 990 Pro 4TB drives intermittently disconnecting, requiring full power‑cycle reboots. Firmware suspected.
- Western Digital / SanDisk 2TB+ models crashing Windows 11 24H2 under heavy I/O due to HMB‑related firmware issues.
3.
Windows 11 24H2 changed how it negotiates HMB with DRAM‑less NVMe SSDs.This caused:- BSOD loops
- Kernel crashes
- System hangs during large transfers
4.
On some systems, 4TB NVMe drives BSOD during boot when controlled by Intel RST.Switching to the Windows in‑box NVMe driver fixes the issue.🧨 What symptoms match NVMe‑related kernel faults?
If you’re seeing any of these, the NVMe is a prime suspect:- Kernel Data Inpage Error
- Critical Process Died
- WHEA PCIe errors
- System freezes with cursor still moving
- Drive disappears from BIOS until multiple reboots
- Crashes during large file transfers or game installs
🧪 How to confirm it’s the NVMe (quick tests)
- Move Windows to another drive temporarily If crashes stop → the NVMe or its driver/firmware is the cause.
- Disable HMB (if DRAM‑less) Registry tweaks can stabilize affected drives (performance drops).This was a known workaround for 24H2 instability.
- Switch NVMe driver
- Try Microsoft’s nvmedisk.sys (25H2+ feature flag).
- Avoid Intel RST for standalone NVMe drives.
- Update firmware Samsung, WD, and SanDisk all issued firmware fixes for NVMe‑related BSODs.
- Check Event Viewer → WHEA‑Logger If you see PCIe Bus/Device errors → NVMe controller instability is likely.
🧠 Bottom line
A 4TB NVMe absolutely can cause intermittent kernel‑level crashes in Windows — not because it’s 4TB, but because large‑capacity NVMe drives often expose firmware, driver, and HMB‑related bugs that smaller drives don’t hit. Multiple real‑world cases and vendor advisories confirm this.Yeah, so straight-up, I'd update the drivers and see what happens. But more than likely I'd try the smaller SSD and see if the problem disappears. Again you mention in a previous thread that you had this issue on another PC with the same SSD. That seems to suggest a common cause.
Thank you so much for the help and info! How do I access WHEA Logger in Event Viewer? Also how do I go about switching nvme driver?
Hi again guys. I have installed all updates for my Legion laptop that it could find in both windows update and the pre installed Lenovo Vantage App/Program. How do I install updated firmware for SSDs, and also how do I switch to nvmedisk.sys driver that was made by Microsoft? I am not sure what driver(s) the SSDs are currently using. Help greatly appreciated 🙂
I'm not going to give you any direct links for the subject, as after doing some preliminary research, it seems like switching to the newer NVMe driver has the potential to bork your OS.
If you're interested, I would suggest doing some Googling and finding out more answers and reading through people's experiences with doing it. It seems to be relatively half baked at the moment, so do it at your own risk.
