Casual screen flicker and slow-ish mouse

[droplotus]

Hello, I'm having a problem that i don't know why it even started.

I have this 2 in 1 laptop for almost a month and it was just perfect, loved it. But from one moment to another, my left speaker just went off, I searched and it was a BIOS update problem, so I fixed it. After two days it was my touchscreen that didn't detect my finger in some areas, another updated fixed it, but for every 2-3 times I boot my pc, I have to restart it because that touch problem isn't 100% resolved.

Now my problem is another, I tried everything, hardware check from Pressing ESC on my boot, update everything, I even did a clean windows 10 installation (from Settings), nothing worked:

My screen from time to time it flickers like it was broken or something (1 time per 10 min +- and its the whole screen, not the bottom corner as I've seen people complain about) and my laptop is just too slow! When I move the mouse (on the touchbar or with an USB mouse) it is slow, not the speed of it but it seems like it's not 60hz but 30hz-ish, I mean, it's not smooth, not even a bit. I found something "funny", when I use malwarebytes(the program), my laptop returns to it's original state while the program is running, my mouse gets smoother(like it should) and pc is faster, after the program stops working, it goes back to the slow pattern.

I didn't want to return the pc to the store because I really need it for my studies right now and it would be a pain to wait 2 weeks for something that could be fixed here by one of you!

Thank you and I hope some of you have a perfect solution to my problem.

Joao Sousa.

@droplotus,

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. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I understand you are having issues with the HP Spectre notebook. No worries, I'll be glad to help you.

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

Have you recently made any software or hardware changes on the PC before the issue started?

Have you tried to run an extensive system test from F2?

Have you ensured that the drivers are updated either using Windows update or using HP Support Assistant?

Have you checked in the Bios if the screen flickers? Have you tried to connect to an external monitor and check if the issue persists?

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

Let's start off by performing a Hard reset on the notebook: 

Before power resetting your computer, do the following:

1. Disconnect or remove all peripheral devices. Start up the laptop and test the computer by itself, and then reconnect one peripheral device at a time.

2. Turn over the computer and look for a battery compartment door.

   • If there is a battery compartment, use the steps in Reset a laptop with a removable battery.

   • If there is no battery compartment, use the steps in Reset a laptop with a sealed or non-removable battery.

 I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings. That way it will look at the Hardware installed on the Notebook.

Once done, restart the computer and check.

Step 2: Connect an external monitor to test the display:

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Step 3: ​​​​Boot the computer into the Bios screen and check if the screen persists.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the  F10 button repeatedly

Once you are in the BIOS, if the screen persists, it is likely a hardware failure.

If the screen is not distorted in the Bios, then this could be a software or driver issue. 

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

Download and install the troubleshooter from this link.

Now try to perform Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

If the issue persists, I would suggest here is to uninstall the display drivers on your PC from device manager.

Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.

Check the box that states delete the software for this device.

Now restart the computer and then update the Bios, Chipset and graphics card drivers on your PC either from our HP support website, using this link or download it using HP Support Assistant

Download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

If the issue persists, I would suggest the next step would be to run a test an extensive test on the graphics card which is listed under Component test

You could also try to run an extensive test on the system. (Please capture the failure ID for further assistance).

Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, please. Please note that I am not overloading you with a lot of troubleshooting steps. Instead, just like you, I am eager to ensure that the problem gets resolved. So I am providing you with more resources and information at your disposal to deal with the situation better.

Hope this answers your question.

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
