Ask HN: The potential of DIY rewiring ThinkPad E14 board to ignore soldered RAM

1 pointsby amtsover 2 years ago
On the basis of 1,2 is it possible to resolder all Serial Prescence Detect module resistors to position 0 to make BIOS to expect zero soldered RAM and switch to socketed RAM? +any other operations on the board to make BIOS ignore the soldered RAM and use only socketed RAM?<p>[1] https:&#x2F;&#x2F;hackaday.com&#x2F;2021&#x2F;11&#x2F;24&#x2F;you-cant-upgrade-soldered-on-laptop-ram-think-again&#x2F; [2] https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=34019875#34027831

why?<p>The only reasons I can think to do this are 1) the onboard RAM has errors 2) the socketed RAMs specs are so different from the on board that it creates errors.
