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 😊...

Hi all,

I have a Western Digital Sentinel DS5100 NAS system which has stopped working. It has dual BIOS. I bought the system second hand with an already broken primary BIOS (it rebooted multiple times until second BIOS was used).

It worked until recently. The system was idle in Windows Server 2012 and a BSOD occurred, I think it was 'critical process died'. Thereafter it didn't boot, it just sat there with no video output and fan speed at 100% (there's a proprietary Windows driver by WD which controls the fan, outside of that it always runs at 100%).

There...

Hello esteemed members. I appreciate that my question will strike some as being somewhat childishly simple, but it genuine perplexes me! I have repaired several laptops before by removing a faulty capacitor that was short-circuiting the motherboard, whereupon the laptop would then work. For me, it begs the question that, if the current can bypass where the capcitor was when it has been removed, why didn't it just bypass it when it was present and faulty,? I can't get my head round the premise that if the other side of the capacitor is connected to ground, then why doesn't the current simply bypass...

The model is 15ec-1061nm
Board number is DAG3EDMB8D0​

SO i turn the laptop on , and as soon as it starts booting from disk, from usb, windows,linux,HBCD,anything i boot it just turns off....while in bios menu or in linux boot menu it stays on normally...It's like when it starts to use graphics it shuts down...But i measured 0.72V while working on the GPU power line,no excess heat is comming from GPU or CPU, i even removed the heatsink and turned the laptop on and everything worked fine, got a bit hot, fan span to full speed, but it worked like that for few minutes in bios...

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...
