If you have strong hands-on ability and are willing to take the risk (failure to flash may lose the warranty), you can consider flashing the machine yourself. Lenovo asks the firmware area.

If you are not familiar with the flashing operation, it is recommended that you go to the local after-sales maintenance station to upgrade the flash. For specific tariffs, you can consult the staff of Lenovo authorized maintenance stations and service stations.

You reboot the machine first, if it's not the problem with the screen itself, it should be solved, otherwise the touch screen may be broken.

If you don't talk about the specifics, it's hard to know why you're not successful!!

You've tried it yourself many times without success, so I suggest you just take it and let someone else brush it for you. It's not expensive, up to 50 yuan to get it!!
