Re: Dell 3542 2 beep error

DRAMRST should be 1.3V approx it's upll done by R410 test it both sides

Hmmm... All voltage are ok. (vtt, spd, sda, scl, dramrst, o.v ) but 2 beep
do you have a another idea

Re: Dell 3542 2 beep error

you are saying you found R410 and now you have 1.3V whereas on the other hand you are saying dramrst 0v. Do you mean you have 1.3V on one side of the resistor and 0V on the other side??I beleive Dram_RST signal is supposed to be from PCH(single die in this case)

Re: Dell 3542 2 beep error

i'm R410 resistor replace. before 1.3v come ram 30 pin. but 2 beep.

So you replace the R410 but still 2 beeps?

test the RAM slot Pin 1 126 203 199 75 200 202 voltages ?

I have a 4gb ddr3l ram

Re: Dell 3542 2 beep error

Pin 1 = 0.67v, 126 = 0.67v, 203 = 0.67v, 199 =3.39v, 75 =1.36v, 200 = 3.39v
202 =3.39v

OK now test VCC CORE, SYS PWROK, PLT RST ,(LPC FRAME, LPC AD you need a oscilloscope) try with the multimeter CLOCK X1801 XTAL 24.Mhz
