Help I have an acer spin cp713, 18 months old, it's useless, and acer don't or won't repair it free of charge despite the fault having been there since just a few weeks old. The issue is that I keep getting the mouse and cursor point flashing and disappearing causung spurious operations of Web pages, I thought its maybe caused by the trackpad dirt or dust or dirt under a key on keyboard but I've cleaned, vacumed and sprayed it with wd40, no difference, I've hard reset it, power washed it several times, run in in the beta and stable channels, run it in guest mode, if fact everything recommended has been tried, still to no avail, it seems to be getting worse, sometimes if it's switched off and cold it might behave for a while when switched on, but when it warms up that's it, its unusable, u can't click on anything, even holding down trackpad doesn't stop the shelf position screen keeps flashing on an off. What's the cause, its driving me nuts, this was £649, not cheap for a chrome book, and it's frankly rubbish and unusable, anybody had same issue? What's wrong with it, I'm convinced now it's not software, it's hardware, Acer are u listening? A quality device should last years, this only worked for a few weeks, help from anyone in the acer community on this would be much appreciated many thanks.
