loud fan noise when starting up and automatic shutdown 10 seconds after pressing power botton

[JMao]

Hi

There is a lould fan niose when starting up my ENVY TouchSmart 14 Sleekbook,  the noise lasts about 5 seconds, then the laptop automatically shuts down  and never starts the operating system. From pressing the power botton to shutdown, it takes about 10 seconds.

The problem happened from yesterday evening when I was watching a movie on TV, the movie is casted from my laptop via Chromecast. I thought the laptop would become hot after a while, so I sat the laptop on its left edge (obviously not a normal position). Suddenly, the screen went off and it started to shut down. I though it was because the battery power was going to run out, so I plugged in the power adapter and try to wake up the laptop with pressing the power button, but since then the problem's started  and keeps happen. 

Please help solve the problem, thanks!

This is normal.  At power-on, the fan initially runs at 100% speed, until the motherboard measures the temperature inside the computer, and then determines that there is no need for that speed, given the current "cool" temperature, and the motherboard then tells the fan to slow down, and thus make less noise.

Obviously, this is not normal.

Where are the exhaust vents, where the warm air is pushed out?

On my LENOVO laptop, the vent is on the LEFT EDGE.

If your laptop is similar, you may have blocked the exhaust vent, and have caused overheating.

I don't know why your laptop, after cooling-down, will not start.

If the computer's warranty is still valid, contact HP Support.

If the warranty has expired, take the computer to a qualified computer technician, for professional trouble-shooting.

Thanks for your reply, mdklassen

The vents are right below the fan and RAMs, and also on the front edge. The laptop is not overheated now since it has not been working for a whole day 

I have tried what I can today, including 1) blow away all the dust, 2) pull out the RAMs, fan, battery, hard drive out and plug into the mother borad again, 3) use the fan, hard drive, and RAM of my another laptop. Nothing good happens.

However, I managed to get into the BIOS and system hardware test menu, and the laptop surprisingly does NOT automatically shut down but the fan noise keeps loud never stops. I have done a quick system test, showing no error on any hardware. Now I am running an extensice test to see if there is any hardware is broken down.

Unfortunately the laptop is out of warranty, otherwise I will send it to the cumstom service directly. I do not know what to do next if the system test result is positive before I resort to a professional.

I find it unusual that an EXHAUST vent is located on the front, but, hey, who knows ?!

Your computer: https://support.hp.com/ca-en/product/hp-envy-touchsmart-14-k000-sleekbook/5375380/manuals

but, today, HP's web-site is listed as "under maintenance", and is extremely slow to respond.

So, I cannot access its "user guides" to get pictures of the intake/exhaust vents.

From: https://support.hp.com/ca-en/product/hp-envy-touchsmart-14-k000-sleekbook/5375380/document/c01657439

Step 6: Testing for hardware failure

If overheating issues persist after cleaning the vents and moving the computer to a cooler room, a hardware component might be damaged.

Test the computer to see if any hardware, such as memory, the processor, or the graphics hardware, have failed.

I am worried that the overheating may have damaged the motherboard.

Got a spare "desktop" computer (all you need is working motherboard, RAM, keyboard, and video) ?

Disconnect any existing disk-drive, and connect the disk-drive you have removed from the laptop into the desktop.

Try to boot from the disk-drive, and see if it least starts to boot.  If so, your disk-drive, and your personal files, are OK.

HP PCs - No Power or No Boot Guided Troubleshooter

Perform a clear CMOS (Notebooks)

For notebook computers introduced after 2016, follow these steps to reset computer CMOS data.
Go to HP Customer Support to review the service or user guide for your PC for specific instructions.

NOTE: Notebook computers produced before April 2016 might require temporary removal of the CMOS Real Time clock battery and primary battery to reset. Refer to the unit service documentation to find this, or continue troubleshooting the issue in this guide.

1. Turn off the computer.
2. Press and hold the Windows and the V keys.
3. While still pressing those keys, press and hold down the Power button on the computer for 2-3 seconds.
4. Release all the keys.
5. At the completion of a successful CMOS reset, a CMOS Reset (502) message displays.
6. Restart the computer. If the symptoms persist and the computer does not start after the CMOS reset, continue troubleshooting the issue.

Hi,

In the ten seconds does the HP logo come up on the screen? If you turn on the PC and press ESC continuously does the menu come up? It could be an overheating problem.

Let me know,

David

thanks for the advices

I managed to reset CMOS successfully, since I saw the CMOS Reset (502) message on the display. And I also updated BIOS. Sadly, neither helps startup the operating system.  I followed every steps of the 'No Power or No Boot Guided Troubleshooter' until it suggests me to 'service the product'. Now I am trying to retrive my data stored in the hard drive, at least get something back ...

yes, the HP logo shows up if I do not press any key, but after 2 to 3 seconds, it powers off. If I press ESC, the startup menu comes up (pls see the figure), and it is very strange to me that under the startup menu, if I do not press any key, it will not power off. and if I press  F2 or F10 to go into system diagnotics or BIOS setup, it also does not powers off. 

what is the essential difference between entering startup (press ENTER key) and entering  system diagnotics/BIOS setup (press F2/F10)?

I understand that if you do NOT allow it to try to load Windows, it will not power-off.

Pressing ENTER "works" the computer very hard, to load Windows.  Does it successfully complete that task?

Pressing F2 launches the built-in HP Diagnostics, to "test" the components of your hardware.

Pressing F10 enters BIOS SETUP, where you can see details about your computer, change options, and change the boot-order, and much more.

[JMao]

that is right, it automatically power off only if the HP logo appears, which happens when I try to load the operating system  (the laptop actually have both MINT 17 and Win 8.1) and system recovery (press F11), can I assume that the problem is related to the operating system, either loading or recovering it? 

Given that the computer does not power off in some cases like system diagnostics and BIOS setup, can I assume the hardware compnents including the mother board? Also, I tried to test almost every hardware component expect the motherboard (memory, battery, hard drive, fan, wifi adapter, card reader) by remove them to see if the problem still happens.
