Every bug must look intentional. How many hidden stuff and easter eggs have you discovered?

Laptop: Dell Inspiron 14 5430 SSD: KIOXIA KBG50ZNS1T02 (1TB NVMe, OEM/removable M.2 2230)

The problem: Getting recurring BSODs specifically when running Chrome + YouTube tabs simultaneously — high load/paging scenario.
Started a few months ago, getting more frequent.
Like at first it was like if i moved my laptop it gave kernel data inpage error but then like in the past 3 days critical error and kernel data inpage errors came up frequently and like the laptop will login but then after that it hangs up.

Took it to service center — they fixed stuff but when i started working this came up again.

Crash details from Event Viewer:
KERNEL_DATA_INPAGE_ERROR (0x7A)
Parameter 2: 0xC000009C (STATUS_DEVICE_DATA_ERROR — bad sectors)

KERNEL_DATA_INPAGE_ERROR (0x7A)
Parameter 2: 0x0 (STATUS_SUCCESS, ambiguous)

After that i did all the stuff given below:

CrystalDiskInfo: shows “Good,” 96% life, but Media and Data Integrity Errors (SMART ID 0E) = 99, Error Log Entries (ID 0F) = 317

HD Tune surface scan: 0% damaged blocks

chkdsk /f /r /x on C: — found only 4KB in bad sectors, fixed some file system corruption (MFT bitmap)

chkdsk on D: and E: — 0 bad sectors on both

After chkdsk:
Then I like it was fine for like a few hours. Like 5 hrs i think. Btw in that time i was training like models in google colab env and had many chrome tabs opens, file explorer , git etc etc etc.

Then this came up
KMODE_EXCEPTION_NOT_HANDLED (0x1E)
Parameter 1: 0xC0000006 (STATUS_IN_PAGE_ERROR — same disk read failure, different code path)

Soooo. What should I do???

Anyone dealt with KIOXIA BG-series OEM SSDs specifically failing early?

Is a fresh Samsung 970 EVO Plus 1TB swap the right call here, or is there anything else worth checking before I spend the money?

so I was watching a video and i turned up the grapics then my computer crashed with a bsod. but it was loud making like a( "errrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" like that really werid.

please tell me what happened and what i can do to fix it

any help would be aprreciated

thanks!

The mid-June BIOS update (Q7CN78WW) for the Lenovo Legion Pro 7 Gen 10 (Model: 16IAX10H) introduces an aggressive Active State Power Management (ASPM) bug that drops NVMe SSDs off the PCIe bus, causing 0x154 UNEXPECTED_STORE_EXCEPTION crashes. Because Lenovo hardware-locked BIOS rollbacks via Intel Boot Guard, the permanent solution requires a two-pronged approach: manually disabling Windows PCIe Link State Power Management, and deploying an automated batch script that forces hidden NVMe latency tolerances to zero to prevent the drives from entering unstable deep-sleep states. Spent two weeks changing parts and troubleshooting to finally pin this down.

The Symptoms

If you are running the 16IAX10H chassis (Intel Core Ultra 9) and experiencing this bug, your system will show the following behaviors:

• The Crash: Random errors are 0x154 UNEXPECTED_STORE_EXCEPTION, alongside 0x3B SYSTEM_SERVICE_EXCEPTION and 0x50 PAGE_FAULT_IN_NONPAGED_AREA BSODs, typically occurring during load transitions in games or while running in Balanced (White) or Quiet (Blue) modes or even Extreme mode.
• The 0% Dump: The BSOD crash dump progress (MAY) stays stuck at 0%. This happens because the SSD has electrically vanished from the bus; Windows cannot write the log file.
• Performance Mode Immunity: The system is 100% stable when running in Performance Mode (Red LED) because this mode natively locks the PCIe bus in a high-power active state ($L0$).

The Root Cause Analysis

Based on cross-referencing global hardware communities (including Chinese Y9000P and Korean Legion forums), this is a synergistic failure of firmware and physical constraints on the Gen 10 motherboard:

1. Firmware (Primary): The Q7CN78WW BIOS altered Intel DTT profiles to save power on Arrow Lake-HX CPUs, aggressively forcing the M.2 slots into $D3_{cold}$ / $L1.2$ sleep states. When a game demands sudden I/O, the SSD controller fails the power-state transition fast enough, triggering a Windows driver timeout.

The Permanent Fix

Do not attempt a BIOS downgrade—Intel Boot Guard will block it ("signed bios guard secure image" error). You must modify the Windows power configurations and automate a script to ensure Lenovo Vantage does not override your settings when switching performance profiles.

Step 1: Disable PCIe Link State Power Management

This prevents Windows from allowing the M.2 slot to enter the unstable sleep states forced by the new BIOS.

1. Press Win + R, type control powercfg.cpl, and press Enter.
2. Click Change plan settings next to your active power plan, then click Change advanced power settings.
3. Expand PCI Express $\to$ Link State Power Management.
4. Set both On battery and Plugged in to Off.
5. Click Apply and OK. (Note: You must repeat this for any other power plans you use).

Step 2: Create the APST Override Batch File

1. Open Notepad.
2. Copy and paste the following code block exactly:

DOS

u/echo off
for /f "tokens=4" %%i in ('powercfg /list ^| findstr "GUID"') do (
    powercfg /setacvalueindex %%i SUB_DISK d639518a-e56d-4345-8af2-b9f32fb26109 0
    powercfg /setdcvalueindex %%i SUB_DISK d639518a-e56d-4345-8af2-b9f32fb26109 0
    powercfg /setacvalueindex %%i SUB_DISK fc95af4d-40e7-4b6d-835a-56d131dbc80e 0
    powercfg /setdcvalueindex %%i SUB_DISK fc95af4d-40e7-4b6d-835a-56d131dbc80e 0
    powercfg /setacvalueindex %%i SUB_DISK d3d55efd-c1ff-424e-9dc3-441be7833010 0
    powercfg /setdcvalueindex %%i SUB_DISK d3d55efd-c1ff-424e-9dc3-441be7833010 0
    powercfg /setacvalueindex %%i SUB_DISK dbc9e238-6de9-49e3-92cd-8c2b4946b472 0
    powercfg /setdcvalueindex %%i SUB_DISK dbc9e238-6de9-49e3-92cd-8c2b4946b472 0
)
powercfg /setactive scheme_current

1. Save the file as NVMe_Fix.bat directly to the root of your C:\ drive.

Step 3: Automate via Task Scheduler

1. Search Windows for Task Scheduler and open it.
2. Click Create Task... (Not Basic Task).
3. General Tab: Name it NVMe Powercfg Fix. Check Run with highest privileges and check Hidden. Configure for Windows 10.
4. Triggers Tab: Click New. Set "Begin the task" to At log on.
5. Actions Tab: Click New. Action is Start a program. Browse and select C:\NVMe_Fix.bat.
6. Conditions Tab (Critical): Uncheck both AC power and battery power conditions so it runs regardless of being plugged in.
7. Settings Tab: Check Run task as soon as possible after a scheduled start is missed. Uncheck Stop the task if it runs longer than 3 days.
8. Click OK to save.
