The tablet is not working.
This model is equipped with a Snapdragon 870.
Pressing the power key using the DC power supply increases the current to 0.14a and returns to 0.00 when the power key is removed.
CPU, RAM, EMC, and rebolling.
The symptoms are the same. I think there's a problem with the RAM, is that correct?
There is no short in the other part, and there is no problem with PMIC.
The same 0.14a comes out when removing the ram​

nuc d54250wykh cpu problem
Hello.
It's been a while since I've been here.
The homepage was slightly changed, but the previous homepage missed it
I'm glad it's still active.
intel nuc d54250wykh
It is a product and there is a problem with the 2.2 ohm resistance in the 19 volt part, so after replacement
3v and 5v come out normally but turn off as soon as you turn it on.
There is a problem with pch power s2~s1, so at the end as shown in the picture
I have a fever.
The problem is that I want to take advantage... -

Re: LA-B843P Rev 1 2beeps
The r410 resistance is measured, and you get 1 mega ohm
I replaced it with 470, but the symptoms remain the same
DDR3_DRAMRST# r404 0.125v....
Other voltages are normal output
Is it cpu memory controller problem?...Last edited by limpidity; 09-14-2023, 07:40 AM.Leave a comment:

Re: LA-B843P Rev 1 2beeps
There was a problem with the resistance, so I replaced it, but the symptoms remain the same
The DRAMRST# voltage is 0.125v, approximately 0.67kOhm when measured by the tester as shown in the ground
working donor board 4kOhm. Is it a cpu problem?...Leave a comment:

Re: LA-9865P boot/power looping
Is it exactly a cpu problem? Or did you solve it? I'm in the same situation
