Thanks

And 2K resistor must be placed at RC123 position.

Do you need to physically remove the memory chips? flash bios?

Re: disable unboard ram lenovo ip3 nm-d151

in my case i have 8gb samsung onboard ram on my motherboard.
R1612 , R1610 , R1608 , R1606 resistances originally placed.
RC123 originally blank.

I moved only R1606 to RC123 and display successfully done on ext. dimm.

and onboard ram permanently disabled. No need pull onboard ram chip.

May be helpful for others

I moved only R1606 to RC123

Will work but R1606 is 10K and RC123 should be 2K, so the proper way to do it in your case is: R1606 must be removed out, and 2K resistor to be added in a RC123 position!

if somebody is strugling like me with resistors, this will show position of resistors for memory disable

One resistor must be moved only.
RC1606 (10K) ---> move it to RC1608 position. That's it.

Thank Bro

Hi,
I have this board:
GV451&GV551 NM-D151
Rev.: 1.0

RAM on board its bad (Samsung)
I moved RC1606 to RC1608 and nothing
I added RC123 (2kohm - (serial 1+1k ohm)) and nothing
maybe I need new bios ?
LCD still black, without battery using 0,39A
I searched the internet and here on the forum, but nothing works.
can someone help please

Double check the strapping of each resistor. With no power, measure the resistance of each position. Compare with post # 26.

I have everything as it is on post 26.
It still doesn't work

maybe the BIOS is also damaged or? If somebody have BIOS pls upload, or Im try find in forum..

Notebook still not working, im using many Bios flies, but nothing happen.
Now LCD still black, white light working, without battery using only 0,02A nothing is short and when Im plugin battery start charging normaly.
Im lost....

Post your bios in the "Bios requests ONLY!" forum and someone will take a look at it. You can try the RAM patcher for now https://www.badcaps.net/forum/troubl...63#post3172363

This tutorial works 100%
Like all the others who give the same instruction only in a different way.
It doesn't take much to philosophize.
With the BRD scheme and the brain, it is solved without problems.
If the motherboard still doesn't work, then you have another problem.
My board had symptoms of drawing around 750mA and climbing slightly as the CPU warms up.
As soon as I failed with reprogramming the EC and Main bios, I went to disable the RAM memory.
Immediately after the first startup of the motherboard, the current began to work variably and the image appeared without problems.
So the instruction is checked and works.

I have 4 gb onboard , move R1606 to RC123 and works? Thanks.

In RC1608, I have one resistor 10 Kohm, and RC1606 is 10 Kohm too. Thanks

Thanks, I can disable the memory!!!!
