HP ENVY TE02 Desktop PC won't boot

[DR-H]

Hi, I have bought my PC Desktop Envy TE02 a year ago,  I mostly used sleep mode not power off.

recently I experience cold boot. when I press power button, the power led turns on, fan starts, but nothing else, no booting, no display, no keyboard or mouse. 

then when I try to power off by holding power button for 30 or 60 seconds, it doesn't power off, 
I have to unplug, press power button when unplugged for 30 seconds, then plug in, and power on again.

Sometimes that works but sometimes I have to do this several times. 

my BIOS Firmware is latest, and checked all devices are ok. 

My guess is PSU is having issue. but there is no other PC I can check the PCU with

Hi @DR-H,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your PC!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Power Cycle the PC:

• Unplug the power cord from the back of the PC.
• Press and hold the power button on the PC for about 30 seconds.
• Reconnect the power cord and turn on the PC.

Check for Peripheral Devices:

• Disconnect all external peripherals (e.g., USB devices, printers, external drives).
• Attempt to boot the PC with only the keyboard and mouse connected.

Resetting BIOS Settings:

• Clear CMOS
  • Turn off the PC and unplug from the power source.
  • Open the PC case and locate the CMOS battery (a small silver coin-shaped battery on the motherboard).
  • Carefully remove the battery for about 5-10 minutes.
  • Reinsert the battery, close the case, and reconnect the power.
  • Turn on the PC.

Check for Hardware Issues:

Reseat RAM:

• You might need to open the side panel of your PC.
• Locate the RAM modules and ensure they are seated properly.
• Remove and reinsert the RAM sticks to ensure a good connection.

Check GPU (Graphics Card):

• Ensure the GPU is properly seated in its slot.
• If possible, remove and reinsert the GPU.

Check Connections:

• Ensure all internal connections (e.g., power cables to the motherboard and drives) are secure.

I hope this helps.

Thanks for your reply. But didn’t work.

so far I have done these:

1. I have replaced the whole CMOS with new battery

2. I have checked all devices, I can eventually turn the PC on and go to OS, but it doesn’t happen sometimes. 

3. So memory is ok, Graphic card is ok. Connectors and cables are OK

4. I have ran HP diagnostics and all devices passed

5. I have tried unplug, holding power. Not success

6. There are no external device, just mouse and keyboard 

The Scenario to turn on is this:

so if I turn the PC for couple of hours, either unplugged or just turn off, like cools down. When I turn it on, the power button and fan works. But no keyboard, no mouse and no monitor screen.

then I leave it like this for couple of minutes, then I unplug it, and turn it on.

sometimes this need to happen several times before the PC starts correctly. 

But when it starts correctly, with restart, or turn off with like 10 minutes apart, works fine
