My HP Envy x360 will not boot

[Justin316]

The laptop is an HP Envy x360 160ac0023dx. Both power LEDs will turn on, but nothing else happens. This happened after I disconnected the battery for maintenance. 
The laptop was fully working before I did this. 
I've already tried:
AC-power only trick (remove battery, hold power button, then try turning it on). This didn't help.
Remove the SSD to reduce motherboard stress (spoiler alert: this didn't help either).
Extended AC-only power trick (remove battery, hold power button for 20-30s, then try turning it on). This didn't help either.
I'm starting to think I bricked the motherboard. The laptop is also out of warranty - I cannot RMA it. 
Should I just remove my SSD and tell my dad I need a new one? I'm out of ideas.

Hi @Justin316,

Welcome to the HP Support Community.

Thank you for posting your query.

I am sorry to hear that your HP Envy x360 160ac0023dx laptop is not booting after you disconnected the battery for maintenance, follow these steps to troubleshoot the issue:

BIOS Recovery Mode

• HP laptops have a BIOS recovery feature. Hold Windows + B while pressing the power button. Keep holding until you hear beeps or see the BIOS recovery screen.
• Check Battery and AC Adapter:
• Ensure that the power adapter is correctly connected to your laptop and a working power outlet.
• If available, try using another compatible adapter to test if the adapter is faulty.

Perform a Hard Reset:

• Power off the laptop and disconnect any peripherals.
• Remove the battery only if it is detachable. Leave the AC adapter connected.
• Press and hold the power button for 15 seconds.
• Retry powering on the laptop.

Check for Beep Codes or Blinking LEDs:

• Note any beep sounds or blinking LED patterns when you try to power on the device. This can indicate a specific hardware failure.

Reseat Internal Components:

• Since you previously disconnected the battery, ensure that it and any other components, like RAM or storage drives, are securely connected.

Check the Display:

• Press the F8 key repeatedly during startup to check if the display has failed but the laptop is still working.
• Try connecting your laptop to an external monitor to check if there is a display output.

Perform a CMOS Reset

• Disconnect both the main battery and the CMOS battery.
• Hold the power button for 30–60 seconds.
• Reconnect the CMOS battery first, then the main battery, then try AC-only boot.
• This often clears “no boot” states caused by BIOS corruption.

Take care and have an amazing day!
