HP OMEN 15-dc1101nc DAG3DDMB8C0 - 3long 2short blink of capslock

[ktmmotocross]

Hello.
Iha this HP OMEN 15-dc1101nc DAG3DDMB8C0 that makes 3long and 2short blink of capslock with no post. That code tells that error os in memory initialization. I try to flash bios, resolder memory connector, but no luck.

When start i have all voltages except one coil in CPU power which i see on some laptop that it must not be there

Have u checked ram voltage on slot pins. Are requirement for ram ic all fulfilled??

Start by Programming the bios first...
Then do this but be very carefully, inject one volt on the coil, and then start the machine while the 1v is injected and see if the machine will boot...but before all these start by programming bios with a well known working bios

i measured 1.2v on capacitor on memory module

Thats not enough man. You need to measure the slot pins.

what pins?

this is the coil without voltage. resistance is 3ohm, on other cpu coils is resitance 1.6ohm

You cant check that coil with DMM. Still check while you turn on there should be slight deflection on DMM. If it is so, then nothing wrong there.

what pins?

VDDSPD,SMB_DATA,SMB_CLK,DRAMRST# to name a few. You can refer to any schematic with ddr4 ram module.
