Hi and happy new years !

I have this laptop with a short to ground on PPBUS_G3H_P5VS4 on C7667.
I first replace this caps with a caps from another board, that fix the short.
Laptop works for a few days and start restarting randomly with Mac Os loaded or during loading or even before mac os loading or worse no image and current cycling up to 0.6A...
Then i replace again the caps, same thing... then i replace the 65 66 and 67 caps with new laptop from mouser, same symptom.
I use those caps:

I tried with or without battery, with or withour battery, keyboard... and board naked on my desk, same symptom. (i see the current

Any advice, in what direction should i look?

Thank you

Changed C7667 is not the problem.
The machibe can wotk even without it.

If you used hot air to replace it, the heat could affected the board somehow.
Did you find any liquid sign on the board?
