820-00244

Anyone more familiar with a1534 820-00244? Trying to figure if is a board or parts problem, don’t have any donors to test at this moment.

Takes a little longer to boot, and no mouse or keyboard detected. One or two times, mouse worked, but it froze and powered off.

Did some measurements and all rails looks ok!
Should I buy a keyboard/mouse flex first?

Does It take longer to boot without mouse/keyboard?

I’m doing some research on how this machines works, but any thoughts to share would be appreciated!
Tks

Bad flex or bad trackpad are common on these. Trackpad has sensor in it and when it is missing board will run slow.

Got it, just bought a Flex to try on it first! Get back when arrive.
