Re: Acer LA-H782P-Rev:2.0
Just to complement the picture about onboard memory disable.
The schematic shows the truth table for no memory as:
RAM_ID0 = 1
RAM_ID1 = 1
RAM_ID2 = 1
RAM_ID3 = 1
So you must have RC150, RC151, RC153, and RC224, populated with 10K
And RC155 RC225 RC226 RC227 not populated, to disable the ram.
The resistors changes will be different for the different boards IDs and for the different possible memorys IC brands.
SMDFlea thank you very much, this boardview saved my night. ;DComment

I quiet struggling with board lenovo c681 to disable 4gb samsung onboard ram because they're faulty, I followed the instruction on the schematic to disable them with resistor codes but still not detecting the ram on the slot.
can someone disable onboard ram from my dumped bios, please 🙏
I tried the other bios on this forum with disabled onboard ram, but no success
my final try is to find someone that can help disable onboard ram in my dumped bios attached in this post.
after that I officially give up 😂
thanks for awesome jobs 😊... -

🧵 [Help] Acer Aspire 5 A517-52G – Onboard RAM Removed, BIOS Mod Done, Battery Not Charging
Hi everyone,
I have an Acer Aspire 5 A517-52G-53NB laptop.
The onboard (soldered) RAM was faulty, so I physically removed the chip.
I also successfully modified the BIOS using the SPD Removal Tool – the laptop now boots fine and works with an 8 GB DDR4 SO-DIMM installed.
✅ System status:- BIOS mod is done (SPD removed)
- Laptop boots to Windows normally
- RAM is detected and stable
❌ Problem:
The battery is not charging:- Power adapter

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...
