Caps lock flashing, blank screen at startup, orange led on for key f10

HP Envy14 14t-2000

I've been having this issue for sometime now. . .


My laptop allows me to turn it on and once I do the screen remains blank while the caps lock is flashing once every 3-4 seconds and the f10 key has a orange led light on. After leaving it on for a minute or 3 hoping that the screen turns on, the computer then just turns off.


My laptop has been taken to repair shop but still has the same issues. 


I have also tried about almost everything i have read online on the forums with others who have the same issue. 


The weird thing is i'll pay no attention to my computer for about a day or two after constantly trying to get it to work and it'll then suddenly turn on with a message saying that there is a thermal issue with the fan or something.? 


I would appreciate if someone would help me fix this situation so that i can no longer deal with it in the future.

Hi @mimss,


Welcome to the HP Forums, I would like to take a moment and thank you for using this forum, it is a great place to find answers.


As I understand the computer is not booting into the windows anymore and now it comes up with an error message. Don't worry I'll really glad to help you with this,


To provide an accurate solution, I'll need a few more details:

Have you made any software or hardware changes on the PC?

Was there any update/reset interrupted, recently?


In the meantime, let's try these steps here:


Perform a Hard reset on the notebook


Please click on the below links once you identify the blink code and resolve the issue:

For overheating issue, please follow these steps here:


Symptoms of heat issues and causes of excessive heat

The following list describes some of the issues caused by overheating in the notebook:

* Games stop responding during play.

* Windows stops responding during use.

* Fans inside the notebook become louder because they are spinning faster as the laptop gets hot, to remove the heat.

* When starting the laptop, it sometimes stops at a black screen and does not open into Windows. Windows usually stop responding when it does open.


The following list describes some causes of excessive heat:

* Dust inside the laptop.

* A new component, such as a hard drive, is added. The extra component causes the power supply to work harder and generate more heat. Extra heat also radiates off the new component and adds to the temperature inside the case.

* Over time, some cooling fans might slow down and wear out, as the laptop is getting hot, depending on the usage of the laptop.

* High ambient room temperature.


Step 1: Removing dust and lint by cleaning vents

Step 2: Ensuring proper space for ventilation

Step 3: Updating the BIOS

Step 4: Using HP CoolSense technology

Step 5: Placing the notebook in a cooler room

Step 6: Testing for hardware failure 

If the hardware has failed, capture the failure ID and revert for further assistance.
