A1502 820-3476-A no keyboard or trackpad

[hgoncalves]

Hi,

I have an A1502 820-3476-A, that after a while powered on, the keyboard and the trackpad stop working.

If I connect an USB mouse and keyboard, and reboot the Mac, the internal keyboard and trackpad start to work for a while (one or two days), and them stop to work again, until connected the USB devices again, and the all process repeats again.

Any idea?

Can you help?

First, discard software issue.
Disconnect internal SSD and test with UAB macOS.

Also try known good trackpad flex/board.
