A1286 SOS beeps

04-29-2014, 10:28 AM

820-2532-A is the board model
When it turns on, there is no display, just beeps - 3 short, 3 long and 3 short again - the SOS signal.
I have S0_AND_IMVP_PGOOD 3.3V, so the power supply's are all good.

Did anybody had this SOS problem?

I can's see water damage, but perhaps somebody wipe it off before me, so i am not really sure what is the cause of this failure.

Great experts, help me!

Regards,
Darko

I think that 3 beeps is usually due to RAM malfunction.
If you have checked that then try a slight reflow on the chipset and on the graphics card..

Extreme High Current & Low Voltage Short Killer ??

by DynaxSC

Hi Folks

I'm looking for a extreme high current short killer solution for a reasonable cost.

I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
After taking off the socket, the shorts dissappear again.
The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!

by Stephen

I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.
