Dell 7050 Micro error code 3,6?

Question

Hi! I have a trouble with compact version 7050. It does not start (black screen, no beep sounds). After power on led lights white steady about 15 sec, than it start blinking (3 yellow + 6 white). It seems that i have issue with memory banks, (like error 3, 6 on Desktops), but i can't check it. this unit have only 1 module of ram (4 version for notebook: i can't write different because this site spell checking) and i haven't any replace nearby. If i pull out memory module, then it beeps 1-3-2 and led is blinking 3 yellow.

re: it start blinking (3 yellow + 6 white)

are you sure it is not flashing amber all the time?

Amber LED blinking pattern : The pattern is 2 or 3 blinks followed by a short pause then X number of blinks. The repeated pattern has a long pause inserted in the middle.

3 blinks > short pause >

6 blinks > long pause > repeats

System board failure

Fatal system board failure detected.

There is 2 leds on fron panel: on power button (PB) and hdd activity led (HDD)

All pattern after power on:

PB_Amber->(no pause)->PB_White(steady for about 15 sec)->HDD(once for half second)+PB_Amber(blink 3 times)->pause 2 sec->PB_White( blink 6 times)->pause 4 sec

and repeats continuous

PB_Amber(blink 3 times)->pause 2 sec->PB_White( blink 6 times)->pause 4 sec

PB = power button led.

I've checked SODimm module - it is working fine on another motherboard.

Battery voltage was 2.94v, i've replaced it with new one - nothing changed

try Real Time Clock (RTC) reset

The Real Time Clock (RTC) reset function allows you to recover Dell systems from No POST/No Power/No Boot situations. The legacy jumper enabled RTC reset has been retired on these models.

Start the RTC reset with the system powered off and connected to AC power. Press and hold the power button for 20 seconds. The system RTC Reset occurs after you release the power button.
