Difficulty starting up with power button on HP Envy TE02-1001 PC

[Aslacoe]

Hi

Over the past week my HP Envy TE02-1001 has not been starting up with a simple press of the power button, but is requiring repeated presses. The BIOS is up to date and when it does power up it starts up normally and boots into Windows 11 with no issues.

The number of presses has increased each day and today I have still not been able to start it up. I've opened the access panel and seen that the power button is enclosed within a box behind the front panel, which I have not been able to open to check if there is a loose connection. I have also not been able to identify if there is another element between the button and the power supply that needs to be triggered to start up, and if this is faulty or needs replacement.

Grateful for any suggestions how I might restore normal operation and have the PC start up with a single press of the power button.

Thanks!

This may be a hardware problem that requires opening the system and finding and repairing the problem.

Alternately, and more likely, your laptop is not actually shutting down. It hangs up a critical time on the shutdown and you must do a hard reset such as holding down the power button for 10 seconds to start it back up.

1 - bring up the windows event viewer and look in both the system, and application logs for critical errors.

2 - run the sleep and energy report to identify any problems.

Reference this document

 Windows uses Modern Standby and has two tools to analyze sleep problems that can occur in modern standby.

Energy Report	A list of possible problems ranked as Errors, Warnings, or Informational
Sleep Study	The history of sleep going back several days

These report are obtained by using the Administrators command prompt.
Copy and paste the following into the command prompt window for the energy report.

powercfg /energy .\energy-report.html

Note the number of errors and warnings.

Copy and paste the following commands into the same window to get sleep history

powercfg /SleepStudy .\SleepStudy-report.html

Let me know what you find out.

Hi BeemerBiker

Many thanks for the reply. I think it's a hardware problem, as when it does successfully start Windows performs normally and shuts down cleanly. There are no warning messages on startup and no indication of any power supply problems.

My problem at the moment is I can't turn the PC on to run any software diagnostics. There are no beeps or sounds from the fan when I press the button, just a lack of response.

Hard Reset - Diagnostics

On a desktop system, unplug computer.
If the power cord has a transformer (wall wart) unplug from the computer.
Press the power button 2-3 times to discharge residual electricity.

Plug back in then ---

This is how to do a hard reset

• Turn on the computer by holding the power button down for 20 full seconds then release.
• Press the Power button one more time (if necessary) to start the computer.
• Tap the ESC key about once a second after you see the LEDs on the keyboard flash.
• Press F2 to run diagnostics: (v) 2.6 or later is recommended.

Makes sure you can pass the memory and disk test. If you still cannot power up then check warranty

Hard Reset - CMOS save

On a desktop system, unplug computer and press the power button 2-3 times to discharge residual electricity then plug back in.

Turn on the computer by holding the power button down for 20 full seconds then release. Press the Power button one more time (if necessary) to start the computer and  then repeatedly press the F10 key to enter the BIOS setup menu. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings. Press F10 to Save and Exit.

Thanks - I've tried these but I'm unable to get to the stage where either the keyboard LEDs flash or the BIOS setup menu can be displayed. The PC is unresponsive to pressing the button. It's been like this over the last few days, but repeated button pressing would at some point trigger startup, buttons would flash and Windows would boot up normally. Right now nothing is happening.

Does not look good!

Many thanks BeemerBiker. I think the PSU needs to be replaced or the issue is physically specific to the power button and its connection to the power supply. Rather than fit a new PSU myself and find the issue persists, I'm taking the PC in for  diagnosis and repair.

I have the TE02-0042 and every few days it does an Unexpected shutdown (Windows event 41).

However, power was not lost to any other items on the same AC circuit.

Pressing the power button doesn't turn the unit back on.

I have to unplug the unit from the AC power strip, wait 30 seconds, then plug it back in.

Then pressing the power button starts the PC normally. 

This "crash" and recovery method has worked over 15 times in the past 3 months.

I've done a lot of digging online but don't see a solution.  

I have bios version F.45 and see a version F.46 on the HP site for this BlizzardU  (HP's 894b motherboard) but have been afraid to try a bios upgrade...the system might die during the upgrade.

Short answer: this smells like a power delivery or firmware issue, not Windows itself.

Here’s what’s worth doing, in order:

1. Update the BIOS to F.46.
   Event 41 with no real power loss plus needing an AC unplug strongly points to a motherboard or BIOS bug. HP released F.46 for a reason. The risk of upgrade is low if:

   • You do it from within Windows using HP’s tool

   • You’re on a stable power source (UPS if possible)

2. Disable Fast Startup in Windows.
   Fast Startup can lock the power state and cause exactly this behavior. It’s a common fix.
   Control Panel → Power Options → Choose what the power button does → Turn off Fast Startup.

3. Check / swap the power strip.
   Even if other devices stay on, some strips temporarily cut or filter power in ways PCs don’t like. Plug the PC directly into the wall for testing.

4. If it continues, suspect the PSU.
   A marginal power supply can trip internal protection, requiring a full AC drain to reset.

Bottom line:
Update the BIOS first. This issue is classic firmware-level behavior, and F.46 is the most likely fix.
