What POST card would you recommend for diagnosing laptops?

What post card do you recommend? There is such a TYK .
But in modern laptops there are already other connectors, and there are none.
Who can advise? I am not professionally engaged in repairs, but sometimes acquaintances bring.
For what? Now they brought a laptop, it turns on but there is no initialization, if you press on the board, then initialization occurs, if you do not press it, the light is on for 5 seconds and turns off.
Such a map helped at least more accurately suggest where to look for a crack on the board. Visually, I can’t find it in any way, and the crack is apparently very small because a little pressure anywhere and it immediately turns on.

Judging by the description, you should not meddle in laptops.
There are no cracks in the boards, unless it is thrown off the fifth floor or moved by a KAMAZ. Here it is trite to dump some kind of chip (video, north) from the board - or together with nickels, if there was a blow.
Advice - go and study the laptop1 forum. There is a lot of stuff there, but it will take more than one year to read and understand everything, after which you can try asking questions there (if they don’t immediately ban you for stupid wording or simply demolish the topic).
(you can also read on rom.by, but similar topics without minimal diagnostics and without specifying the full model of the BOARD will be demolished in the sandbox. I started from there, in 2009)
The post card on laptops in the last 10 years is almost useless - quite ordinary, which you have, you can wire it directly to the cartoon (EC) (if you can, there are distances between the legs of a fraction of a millimeter). They just don’t solder to connectors almost anywhere, even if there is a connector. Yes, and the very knowledge of the post codes will only give an approximate direction where to look, it will not fix the laptop itself, and the video chip will not be soldered.
Good luck!
