HP envy

[trengsoba]

Hi, I've got a HP Envy 360 laptop. The other night I had to force switch off as the fan was running incredibly loud, think helicopter type of way. Since then it won't turn on and the charging light won't come on at all. It's showing absolutely zero signs of life. I've only had the laptop about 2 years, if that. Desperately trying to sort it myself as its 3am, does it sound like it needs to be looked at by someone that actually knows about these things?

Hi @trengsoba 

Welcome to the HP Support Community.

Thank you for posting your query.

If your HP Envy x360 is showing no signs of life (no power LED, no charging light, no fan, and no display), it could be caused by a firmware lockup, power circuit issue, battery issue, AC adapter problem, or motherboard failure. Since the issue started immediately after a forced shutdown while the fan was running at maximum speed, trying the following troubleshooting steps before assuming a hardware failure.

Verify the AC Adapter

• Disconnect the charger from the laptop.
• Inspect the charger cable and connector for: Cuts or exposed wires
• Bent or damaged connector
• Burn marks
• Plug the charger directly into a wall outlet (avoid power strips or extension cords).
• If available, try another compatible genuine HP charger.

Expected Result

• The charging LED should indicate

For HP Envy x360 with a non-removable battery

• Disconnect the charger.
• Remove all USB devices, SD cards, external monitors, printers, etc.
• Press and hold the Power button for 30 seconds.
• Release the button.
• Connect only the AC adapter.
• Wait 60 seconds.
• Press the Power button once.

Check the Charging LED

• Connect the charger and carefully observe the LED.
• Possible behaviors:
• Solid White – Charger detected.
• Amber – Battery charging.
• Blinking Amber/White – Possible hardware fault.
• No Light at All – Possible charger, DC jack, motherboard, or power circuit issue.

Try a Different Wall Outlet

• Sometimes the issue is simply inadequate power.
• Plug the charger directly into another wall outlet.
• Avoid surge protectors.
• Try powering on again.

Look for Any Signs of Life

When pressing the Power button, check for:

• Keyboard backlight
• Caps Lock light
• Fan movement
• Screen flicker
• Charging LED
• Heat near the charging port

BIOS Recovery

• Connect the AC adapter.
• Hold Windows + B.
• While holding those keys, press and hold the Power button for 2–3 seconds, then release only the Power button.
• Continue holding Windows + B for another 20–40 seconds.
• Watch for:
• HP BIOS Recovery screen
• Fan spinning
• Beeps
• Display activity

If nothing happens, repeat using Windows + V instead of Windows + B.

Disconnect External Devices

• Disconnect everything, including:
• USB drives
• Mouse
• Keyboard
• Docking station
• HDMI cable
• Printer
• SD card
• Try starting with only the charger connected.

Inspect for Overheating

Because the fan was running unusually fast before the shutdown:

• Feel the bottom of the laptop.
• Smell for any burnt electronics.
• Check whether the fan vents are blocked with dust.

A cooling issue may have triggered an emergency shutdown, but it should not normally prevent the charging LED from working.

Observe the Charging Port

Check whether:

• The charging connector feels loose.
• The charging port moves excessively.
• The connector does not fully insert.
• The LED flickers when moving the cable.

then the issue is likely a hardware failure, such as:

• Faulty AC adapter
• Failed DC-in jack
• Embedded controller not responding
• Motherboard or power management circuit failure
• Internal power rail failure

Hope this helps, Please revert if the issue persists.

Take care and have an amazing day!
