Hi,
I bought a brand new HP Spectre x360 laptop a month ago from Microsoft.com online store.
The touchscreen intermitently goes crazy taking a life of its own including:
1) Switching between fullscreen and windowed every few seconds while watching a video; or
2) The cursor is blinking suddenly at the very LEFT edge while the mouse pointer is blinking at the RIGHT side of the screen and nothing can be done to get out.
To solve these problems, the POWER button is pressed to put it to sleep and then pressing the POWER again to wake it up. The apps would resume normally until the problems happen again the next time. The time between each incident varies so it's intermitent once or every other day the Spectre is used.
I used the HP Support Assistant to check for update and messages and it's up-to-date.
Information about my HP Spectre x360 laptop:
Model: HP Spectre x360 13-4195NR QHD Touchscreen (2560 X 1440)
I'm attempting to update the HP QHD Touchscreen Controller Firmware but hesitate because other users seemed to run into issues when applying them and the touchscreen stops working entirely. Furthermore, there are two versions of the HP QHD Touchscreen Controller Firmware which is very confusing of which one to apply:
sp79382.exe Version: 1.00,A,1 Rev.A Release date: Mar 17, 2017
sp78423.exe Version: 1.00,A,1 Rev.A Release date: Nov 21, 2016
Please someone helps. Thank you!
