There is a chance its a mosfet, (N-channel ) like product by UNIKC corporation or Niko-Semi. (by mark A5 or A1)
From your pic near caps ( maybe with rate value 25v for 19v rails)

Confirm it with remove it from the board, to see pad underneath. The package seem like PDFN 3x3P.
hard to find datasheet from both corps.

sometime we could dig more info from pics from seller on aliexpress or ebay

Many thanks, but its the same ic u think, because the secaond part of marking is a little bit different.

Hello no its not a classical Mainboard, its speciall designed and layouted device in medical services. (but its working like a laptop mainboard)

There are no schematics or a pcb code because the Manufacturer doesnt support.
