Psychotic Keyboard & mouse - Aspire V15 V3-575T-71US

Dexter1952

I have a Aspire V15 (V3-575T-71US) that is giving me fits. When I boot it up, most everything is fine but the mouse acts a bit weird when web browsing. It will not click/open some active tabs. Scrolls when I don't want it to. The after awhile (5 or 10 minutes)the keyboard no longer responds at all. I have done:

Chkdisc - ok
Uninstalled all logitech s/w
DISM health thing
SFC scannow
it has the latest BIOS & W10 updates
checked for the latest drivers thru Device Mngr for the keyboards, mice & video

I did replace the touch screen some months ago with a non touch screen, but it has been fine until recently.

Any suggestions? This thing is not that old to be having all these issues.

Thanx for any suggestions.

You can check the keyboard cable as well.

ps- I also tried connecting a external keyboard via USB to no avail. When the laptop keyboard is working, then the external works also.

Do you already need to reinstall Windows by pressing alt + f10?

Homer1952

Alt F10 does nothing.

I just did the battery reset. Keyboard is still working for now.

Dexter1952

Battery reset didn't work. I am now trying a restore point back to the beginning of this month.

Homer1952

Sorry for the alternate ID as the goggle sign in is my alter ego.

The Acer completed the restore but it still has the issue.

I can only conclude the laptop has a hardware issue somewhere.

I may try a W10 refresh.

Download firmware touchpad synaptics here: https://global-download.acer.com/GDFiles/BIOS/Firmware/Firmware_Synaptics_1.17_A_A.zip?acerid=636033964477380267&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE V3-575T&OS=ALL&LC=pt&BC=ACER&SC=PA_3

I did that update last year. But for the heck of it I ran the batch file again but it did nothing to fix the issue.

Now I am have trouble even entering the numeric PIN to boot W10.

Even in BIOS mode, the internal & external keyboard will not completely work. Arrow keys will not do anything. All I can do is F10 ENTER to exit.

I am beginning to suspect the chipset. This laptop has had an ez lifetime and my first ACER. Never again.

Thanx for trying.

Have you checked if the problem persists in a live linux distribution?

Dexter1952

I don't know how to do that. I am self taught & had a bad teacher.
Just weird that the keyboard will work for a few minutes & then only partially respond.
Sometimes only numeric part of the keyboard works.
I keep thinking is a hardware issue like a capacitor or the chipset IC.
I thought that since this is an Acer forum, the Acer folks would jump in here. Bad assumption on my part.
I am going to try another forum not associated with Acer to see if I get some help.
Thanks for trying. Bye Bye.

You won't believe what it was.

It was the tiny 40 pin connector that goes to the laptop display screen. I removed it, reinstalled it & now the computer works flawlessly. This laptop is supposed to be touch screen capable

It is amazing how integral & necessary it is to have a flawless video system (h/w & s/w).
