Hi all,
This laptop has the blink code 2 amber and 3 white which seems to be RAM issue.
I checked the rails, 1.2V is here, 0.6V is here, 2.5V is here.
PGOOG on Ram IC here too.
DDR4_RST# not present.
In this scenario what do I need to check ?

Hi it is working !!!!!
Many thanks !
But there is still a problem.
PC boot, display ok.
But fans are full speed and manufacturer mode.
When I put the service tag, after reboot still in manufacturer mode and ask to enter the service tag again.
Do you have an idea ?
EDIT : I managed to do it by trying multiple times and reseting to defaut !
Thanks mate, really appreciated !... -

Re: Dell G3 15 3500 RAM issues
You sure it is from CPU ?
In this motherboard it goes through R1581 and become SM_DRAMRST which go to the PCH, it is pulled high to 1.2V at the same time.
Tried a lot of BIOS, for those which boot, same issue.
Tried to replace BIOS Region in FIT. Same issue
My BIOS is 1.24 tried to replace ME Region after extracted the 1.24 BIOS from dell website, same issue.Leave a comment:

Re: Dell G3 15 3500 RAM issues
Ok, my bad, I didn't give the information !
DRAM_RST is low (0.1v) (it's on the pin 108 of the slot, 30 is GND)
The pwr good signal for 0.6, 2.5 and 1.2 is the same (same chip for all) named PWR_VDDQ_PG.
This power good signal enable VCCIO, and it return to EC with R4035 (RUNPWROK) and it is present too.

Dell G3 15 3500 RAM issues
Hi,
On this laptop Dell G3 15 3500 Wistron Selek MLK N18E 19753-1, I have 2.3 blink meaning no ram detected.
I tried multiple BIOS and same.
Have all voltage (VCCIO /CORE / SA; 3V 5V, VRAM, GPU..) except VCCGT.
On the RAM side, have voltage of 1.2V, 0.6V, 2.5V and the PGOOD.
Have 3V on the 3V3S0 coming in the ram socket, and the voltage of CLOCK and DATA coming from PCH to RAM...
I am running out of idea if someone has one..
Thanks in advance

Hi all,
I have one SSD side of the motherboard (U9100, U9200, U9300, U9400) which is dead.
In fact, the 1v8 SSD and 2.5 SDD was short.
Is this possible to replace these NAND ?
I heard about encrypted NAND with the T2
It's seems to not boot even if these is no remaining short on the motherboard... -

Re: FX505GD Realtek ALC233 not working
Sorry for being late, had to do computers.
There is no pull up for the HDA_RST#, but a pull down names R2397. And the value is good.
I did a bridge to a 3.3V directly to the HDA_RST#, but still the same......Leave a comment:
