Hello. I recently bought an acer s7 - 391 and i experience the following problems:

1. i have contrast changes when i swipe trough different apps. for example, when i open the music app, the background looks like it's moving, it wobbles, and the quality of the screen turns very bad.. the colors appear very high in contrast. if i go back to start, the quality starts to look good again, in about 10 seconds. what could it be? i updated the graphic card driver to the latest. nothing.

2. the trackpad is quite bad. when i move the cursor on diagonal, it is not moving straight, but looks like it's drowing some waves, some " s " shapes. ...

3. the display has grey spots in the bottom corners. it also loses some light..

4. my keyboard registers 2 strokes when i press some keys. i type as slowly and as carefully as i can, but it still does.

i think i will go in service with it. does anyone experienced the same problems as i did?

thanks!

Good day

Mainboard is unstable due to the mainboard controller being faulty. Take it to the repair centre for mainboard replacement.

i went to service they replaced my display but the problem with the contrast changes is still there! it only does that when the laptop is on battery.

Hi, saw that you had some grey corners on your last S7. After servicing does your screen still have grey corners?

I have 2 on mine (bottom left and right) and is wondering if it is normal or should I have it servced.

Keep sending/taking it into repair until you get all your issues resolved.

hello! i had my display changed, but after service i still have the problem. they can't to anything about that.

the grey corners from bottom left and bottom right are still there.

[rosustefan]

yes.. i believe it is the only solution. i am dissapointed, i have spent a lot of money and i can't use my device properly...

It is sad that there is do many problems with this laptop. I returned mine for another brand. Try to see if you can do the same if you are unhappy about the s7.

The Acer features auto contrast as well as auto-brightness. I have found no way to disable this. If you go from a very bright image to a darkish one, and look closely you will see small pulses as the auto-contrast kicks in step by step. It balances out a combination of backlight brightness and contrast to optimise the image currently being displayed but it doesn't do it smoothly. This is a design issue though and not a fault.

I have the same issue with double characters when I type. I created a thread in this site dedicated to that issue.
