Where is the mandatory HP service station? \

Hello, thank you for choosing HP products.

According to your description, I suggest you refer to the following information:

1. The contact address provided by HP Gold Medal Service Center is as follows: 2nd floor, No.2 Street, Yiwu Cultural Market 12, next to the gate of Yiwu Digital City, opposite to Wang Bin Passenger Transport Center (Xin Kai Hotel), and bus stops on No.9, No.6, No.2 and No.310.

Tel: 0579-85578444

2. As for the screen flicker in your notebook, please press the F 10 key to enter the BIOS immediately when turning it on, and check whether there is this phenomenon in the BIOS interface.

1. If the BIOS interface is not like this, it is likely that the graphics card driver is not installed correctly or there is something wrong with the system. I suggest you reinstall the graphics card driver. If it doesn't work, please save the data and reinstall the operating system or restore the system to see if there is any improvement.

For how to download the driver of the corresponding product from HP official website, I suggest you refer to the following official documents:
