r5-471t ghost touches appear all over the screen when it is plugged in only, when unplugged its fine? I have to press fn+f10 to turn the touch screen off when it is plugged in or else the touch screen goes wild?

-

I already returned it to default and used other power outlets and its the same..

-

Any ideas?

    If you know someone who has the same laptop, try their charger or take it to a local computer shop and ask to try a charger. Your charger should be Output: 19V 2.37A 45W

    I noticed it does this only when plugged in and at MAX brightness. If I turn the brightness down while its plugged in, it works fine. I guess the screen is sipping too much juice when its plugged in and at full brightness?

     

    Is this normal.. and is there a setting or something that needs adjustment?

    Go here http://www.acer.com/ac/en/US/content/drivers

    Find your laptop "Notebook/Aspire/R5-471t"

    And update your bios and drivers. The latest Bios is dated 4/19/2016 

    and the I/O driver is 10/21/2015.

    Have you had the laptop longer than this?

    Turns out its the charger..I confirmed this when I went back to the store I bought it from and tried my laptop on the display models charger there. Returning the charger for replacement. It is still under warranty 

     

    Thanks for your help

    This is very helpful! I will try this.

     

    I bought an Acer R5-471t about a month ago and I am having exactly the same issue with ghost touches all over the screen, only happening when plugged in. 

     

    Thanks for your input.
