Problems with booting up and purple line on screen

[AljazSeliskar]

Hello!

I'm experiencing problems at boot-up. The computer starts with the boot sequence, and stops to a halt if I have any HDMI screen connected to it. It doesn't come to the windows loading stage. Without a HDMI device connected it boots up normaly. When it halts, there is a purple line on top of the blank black screen on the laptop, nothing else.

Anybody experiencing the same? How do I resolve the issue (apart from booting without the HDMI connected 🙂 ).

Please advise, Thank you!

Best regards

Thank you for joining HP Forums. 

This is a great place to get support, find answers to your technical queries.

I understand that the PC is not booting using the HDMI, need not worry I'll be glad to assist you.

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

Try the same HDMI with the different monitor if available?

Try a different HDMI cable?

Could you please help me with the exact Product number?

Have a great day! Cheers:)

Hello,

I tried to boot up with different types of HDMI cables (low end - have one at the office), golden  and sth. in between. I also tried to boot up with different devices (SmartTV, AOC monitor and a larger display monitor at home). it always the same. 

The thing is, as long as something is connected into the HDMI port, the computer won't start. Even if the HDMI cable is not attached to ANYTHING on the other side. Just the cable. 

If I unplug it, and restart, everything is normal. 

the product serial number is: [edited]

thanks!

Perfect! Thanks for the reply,

Use the following steps to open the System Tests menu when Windows won't start.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the main menu, click System Tests.

   Figure: Selecting the System Tests from the main menu

   

4. The System Tests menu displays.

   Figure: System Tests menu

   

The Extensive Test checks your system to make sure that the main components are functioning properly. It provides a more comprehensive test than the Quick Test. These tests run consecutively through the listed components and can take 2 or more hours to complete.

The following tests are performed:

• Battery check

• Processor check

• System board check

• Hard drive SMART check

• Hard drive short DST check

• Hard drive optimized DST check

• Hard drive long DST check

• Memory extensive check

• Video memory check

You cannot use your computer during the test. The Extensive Test takes 2 or more hours to complete, depending on the system configuration. You can cancel at any time by pressing the Escape key (Esc).

Use the following steps to run the Extensive Test.

1. From the main menu, click System Tests, then click Extensive Test.

   Figure: Selecting the Extensive Test

   

2. Click Run once, or Loop until error.

   While the test is running, the time remaining and test result for each component are shown on the screen. The test can take 2 or more hours to complete.

   Figure: Running the Extensive Test

   

3. If a component fails a test, write down the failure ID (24-digit code) so you have it available when you contact HP Customer Support. The information is also available in Test Logs on the main menu.

   If the System Test did not detect a hardware problem, continue with the Component Tests section.

If the test passes, use this link: https://support.hp.com/in-en/drivers/selfservice/swdetails/hp-envy-15-aq000-x360-convertible-pc/1086... and update the BIOS.

Keep me posted, how it goes!

Have a great day:)
