Acer A317-53 need help to disable faulty onboard ram

[b-slayer]

Hello.
I have an Acer Aspire A317-53 laptop with faulty onboard ram modules, after online searches, I have only found two options to get it working :
- first one is to modify le bios to disable the onboard ram.
- second one is to disable the onboard ram by desoldering some components on the mainboard.

so after some hours google-ing, i have to give-up the modified bios option, main reason is I couldn't find anywhere a such modified Bios, alternate reason is that if windows update makes a bios update, the problem is always here...

so i found that my motherboard is a Chuan Y FH5AT LA-K093P rev:1.0, and I found the boardview file to start searching informations but...I can't find where to start, and whitch component I need to desolder to definitely disable the faulty onboard memory modules...
I can upload the boardview file if interested, and any help will be wellcome

thanks to anyone that can help me save this laptop.

RAM_ID0~3 need to be pulled high to disable on-board RAM.

Hi,
Thanks for your answer, so, when you say "pulled high", you mean "desoldered from the motherboard" right ?
if so, I have to desolder the following resistors ? :
RC3990
RC3991
RC3992
RC3993
RC3994
RC3995
RC3996
RC3997

thanks again for your lights

Pulled high means the ID line is tied to 3VALW_PRIM. The 1 in the table means a high, a 0 is a low (tied to ground). The table has all 1's for no RAM, thus all RAM_IDx lines need to be high.

In other words, 10k resistors need to be fitted to RC3992, RC3990, RC3994, RC3991, depopulate anything in the RC3997, RC3993, RC3995, RC3996 positions. You can reuse the 10K resistors that are currently on the board if you already have 4 fitted.
