overheating after motherboard replacement

[namelesssS]

Hi,

After motherboard replacement in Budapest, my OMEN 16 started having severe overheating (95-101°C) and thermal throttling even in light games. These problems did not exist before the repair.

HP Support already confirmed that the previous repair "was not carried out properly" (screenshot attached).

The laptop has been unusable for over a month. Can someone escalate this case please?

Thank you.

Hi @namelesssS 

Welcome to the HP Support Community.

Thank you for posting your query.

I’m sorry to hear that the issue is still unresolved. Please know that the case has been escalated, and you will be notified as soon as we have an update. We appreciate your patience and understanding while we work on this for you.”

Take care and have an amazing day!

Update: The issue is still not resolved. After the motherboard replacement (Service Order BXLL702501), the laptop now overheats up to 95–105°C and shows multiple new hardware defects. HP Complaint Management (Case 5160063440) has not provided a solution beyond another repair, despite 40+ days of downtime and a clear failed repair. The case has now been filed with the Austrian Ombudsstelle and ECC. I will keep this thread updated.

Hi @namelesssS 

Thank you for responding.

I understand you haven’t received an update. However, after checking the case number provided, I can confirm that the team has already contacted you and requested that you perform some troubleshooting steps and share the results. Meanwhile i will update the escalation team that the issue is still not resolved and to work on it.

Update BIOS and Firmware

• Install the latest BIOS available for your model from the official HP support page.
• After updating, load BIOS defaults:
  • Press F10 at startup.
  • Select Load Setup Defaults.
  • Save and Exit.

Run HP Hardware Diagnostics

• Power off the laptop.
• Press Esc repeatedly during startup and select F2 – System Diagnostics.
• Run:
  • Extensive System Test
  • Battery Test
  • Processor Test
  • Memory Test
  • Storage Test

Document any failure IDs generated.

CMOS 502 Error

Reset the CMOS Battery:

• If you are comfortable opening the laptop, you can try to reset the CMOS battery. 
• This involves disconnecting the CMOS battery, waiting for a few minutes, and then reconnecting it.
• In some cases, the CMOS battery might need to be replaced if it has failed.

If the error persists after a BIOS update and reset, HP may need to inspect the RTC/CMOS circuitry or motherboard.

Check OMEN Gaming Hub Settings

Open OMEN Gaming Hub and verify:

• Performance mode
• Fan mode
• GPU switching settings

Test with:

• Balanced mode
• Performance mode

Observe whether fan speeds respond correctly to rising temperatures.

Update Drivers

Install:

• Latest chipset drivers 
• Graphics drivers   https://support.hp.com/in-en/drivers 
• Intel/AMD power management drivers (depending on configuration)

Also check Device Manager for unknown devices or warning icons.

Have a good day.

Thank you for your reply. I would like to clarify the following:

1. HP Complaint Management (Case 5160063440) has NOT requested any troubleshooting steps from me. The only communication I received was that “another repair is possible”. No diagnostics or instructions were provided.

2. The issues were caused directly after the HP repair (motherboard replacement, Service Order BXLL702501). Before the repair, the laptop did NOT have overheating, EC instability, CMOS 502 errors or thermal throttling.

3. I cannot perform CMOS resets or internal disassembly, as this would void the warranty. HP Austria confirmed that only authorized service may open the device.

4. The device has been unusable for more than 40 days. This is a clear failed repair under EU Directive 2019/771.

5. The case is already escalated to HP Complaint Management and is currently under review by external consumer authorities (Ombudsstelle Austria / ECC).

I kindly ask that this thread remains open until the issue is resolved. Please forward this update to the HP escalation team.
6.  Additionally, HP Complaint Management has already confirmed in writing that the previous repair “was not carried out properly”. This further supports that the current issues are a direct result of the failed repair.
