It is buggy, in fact the Acer laptop keyboard does not work. Carry to the service or on your own?

Question

Iron

Notebook Acer Aspire V5-573G, purchased in October 2014, the warranty has already run out of the campaign.
Suddenly, the keyboard and touchpad began to fail, practically does not respond to pressing. Sometimes wakes up, the text is printed as if stuck. I reset it to factory settings - the touchpad worked, but the keyboard is still buggy. When working with a mouse / touchpad, it works as if Shift is pressed. Klava was not flooded, glitches just suddenly started.
Can I somehow fix it on my own, or look for a service?

Answer 1

Indeed there was a problem in the clave. The cable is built into it tightly, so I solved the problem by replacing the keyboard. I had to tinker, because. The keyboard was held on by plastic rivets.

Answer 2

Connect to a network instead of a battery, or vice versa to a battery instead of a network, and interference can “arrive” from the power supply, they can easily affect the touchpad.

Answer 3

Isn't it drowned?
