HP 250 G8 Notebook desligando sozinho

[WillianLopes]

We have 2 HP 250 G8 notebooks (TPN-C139).

This week one of them started giving a blue screen and turning off by itself. It turns off and takes a while to come back on. After a while it turns on normally but turns off again.

Due to this characteristic, we changed the thermal paste and cleaned the cooler again (we had already changed and cleaned it recently but decided to do it again).

However, the problem persisted.

Now, the surprise: another notebook of the same model started to present exactly the same problem this week. These notebooks had never had any problems before this week.

Is it too much of a coincidence that 2 notebooks of exactly the same model present the same problem so close together? No other notebook had any problems.

Any suggestions?

Hi @WillianLopes

You are correct—it is highly unlikely to be a coincidence that two identical notebooks began exhibiting the exact same spontaneous blue screen and shutdown issue within the same week, especially after a recent successful thermal management maintenance. This pattern strongly suggests a common software or firmware trigger rather than a simultaneous physical hardware failure on both units.

For starters,

1. Check for Blue Screen Error Codes: On the next blue screen (BSOD), look for the Stop Code (e.g., SYSTEM_SERVICE_EXCEPTION, MEMORY_MANAGEMENT, CRITICAL_PROCESS_DIED). This code is the most valuable clue for diagnosing the driver or system file responsible.
2. Uninstall Recent Windows Updates:

• Go to Settings > Update & Security > View update history > Uninstall updates.
• Remove the most recent Quality Updates or Feature Updates installed just before the issues started this week.
• Check if there is a BIOS update available on the HP support website for your model. Sometimes, BIOS updates can address stability issues.

NOTE: Safe Mode: Boot the laptop into safe mode to help decide if third-party software might be conflicting.

This may also be due to hardware issues. So, check for that as well by doing the following:

1. Check Memory and Storage:
• Run Memory Diagnostics: Use Windows Memory Diagnostic Tool to check for RAM issues. Access it by typing mdsched in the Windows search bar and following the prompts.
• Check Disk Health: Use utilities like CrystalDiskInfo to assess the health of your storage drive. Corrupt sectors or failing drives can cause unexpected shutdowns.
2. Battery and Power Supply Often Turn Off If Failing:
• Ensure that the battery is holding a charge and the power adapter is functioning correctly. Sometimes a loose or faulty connection can cause power issues.
3. Run a hardware diagnostic test:
• Reboot the PC.
• While the PC is booting up, keep pressing the F2 key to enter the UEFI diagnostics.
• Select System Test > Extensive Test.
