#1 Acer A315 problem z zaprogramowaniem KBC

Cześć,

platforma jak poniżej:
Acer A315
LA-E892P rev 2A
KBC KB9022Q D

Jestem w posiadaniu SVOD 1 z modułem keyboard. Za nic nie mogę się połączyć z KBC na tej płycie. Pinologia jest w porządku, KBC zasilane jest, #ec_rst w stanie wysokim. Wylutowałem też kość bios, ale nie pomogło. Jakieś pomysły jak zmusić tą płytę do współpracy z programatorem?

Hello!

In this case the first pin is on the right side, not left. Please, change this option and try again.

Hi matic, the motherboard has upside down connector. This option is correct. Althouht I was tried - KBC not detected.

You are right. Sorry my fault.

Have you connected the ground cable between the motherboard and Svod programmer? Note that the ground connection via a mini USB cable has sometimes a poor contact, so it's best to use a regular wire and solder it.

If the ground is fine, what are the symptoms of failure on this motherboard?

Ground is fine, I tried direct soldering wire.

The laptop can turn on by pressed anyone key. The key must by pressed constantly, else laptop will turn off. I checked keyboard via svod and it's look great. I admit it I did't check another keyboard.

Set your multimeter to the diode test mode and measure the voltage drops to ground on all pins of keyboard connector with the positive (red probe) connected to the ground.
