Witam serdecznie, pacjent to Lenovo Ideapad 320S-14IKB 81BN. Płyta: CIUYA/YB/SA/SB/SD LA-E541P rev:2A

Problemy z działaniem klawiatury oraz touchpada. Po dłuższym okresie bez zasilania płyty, tj. kiedy mierzyłem, wymieniałem, programowałem, wtedy klawiatura oraz touchpad zaczynają działać. Po restarcie systemu już nie działają.
Jest szansa że laptop był zalany - opowieść była taka że się nie włączał, inny serwis go czyścił i po czyszczeniu zaczął działać. Po dokładnych oględzinach nie znalazłem niczego podejrzanego na płycie.
Przycisk power znajduje się na klawiaturze - on działa bez zarzutów.
Na początku kiedy odpaliłem Hirensa, wszystko było w normie, więc myślałem że to kwestia systemu. Później jednak problem znowu pojawił się i w hirensie, i w windowsie zainstalowanym na dysku.
BIOS przeprogramowany, ME region czysty. Wymieniony układ KBC, również przeprogramowany. Po wymianie, w pierwszym starcie wszystko było OK, później po 3 resetach znowu klawiatura i touchpad nie działają. Proszę o pomoc w dalszym rozwiązaniu problemu.

Hello!

- Does the keyboard also not work in the BIOS?
- Connect an external USB keyboard and check if it works, when the internal one doesn't.

I couldn't even enter setup by vantage button, because I couldn't select it in the menu.
I have a huge mindblow right now because after the weekend it seems like it's working perfectly fine now :frustry: I restarted whole thing 20 times and it's fine. I did nothing. But I don't trust it :D

EDIT: the problem came back. External keyboard is working fine when internal doesn't, same as mouse.

EDIT2: Actually the laptop was on sleep, not turned off and when I open it up, the problem came back.

Is it the same in BIOS?
Press the "F2" button on external USB keyboard to enter the BIOS.

Yes, F2 button is working on external keyboard, same in BIOS.
EDIT: I mean when internal keyboard is not working, the external one works fine in BIOS.
