Thanks.
Unfortunately it is very different but I have been able to find the original. Greetings...

I found the schematic diagram on another site. I'm adding it here to add it to the badcaps library. I'm glad to be able to collaborate with something that wasn't here. Greetings to all and happy Easter...

Clevo 6-71-NL4L0-D02 schematic
Hello
I need schematic for motherboard Clevo 6-71-NL4L0-D02
Other code; NL40LUMB-0D

Thanks for answering
I don't know how my confusion arose. However, the pins remain the same, I compared the diagram of the laptop that I am repairing with the diagram of the motherboard from which I took the PCH, if there is any difference I don't know what it is, since even the RTC crystal oscillates with the replacement PCH that has different nomeclature.
Excuse my English, I use Googlr translator...

BD82HM65 Intel SLJ8C Vs SLJ4P
Hello friends:
ThinkPad S230
Mother: LA-8671P REV 1A
Does anyone know the difference between these chipsets and if they can be replaced with each other? Does anyone have experience swapping one for the other.
I have doubts about my PCH BD82HM65 (SLJ8C), the 32.768Khz crystal does not work.
In its place I put a BD82HM65 (SLJ4P). With this new PCH the RTC crystal does oscillate but the equipment in general does not start.
Comparing diagrams, the SLJ4P and SLJ8C use the same pins, but I don't know what the difference would...

Sorry for not understanding the forum rules. This post is dated 2018. If in 6 years no one uploaded the requested file, why are they going to upload it now if no one sees it? 6 years passed. How do I so that current users can upload files that have already been requested here a long time ago?

Hello. I need the .bin file for this mother, on the official website it only has to update from Windows. I need the latest version since the Rizen 5600G processor needs an updated BIOS version. On the official website the file is .cap and it is not useful for recording with the ch341....

Diode PDB1 is good.
The input FETs are good. I even changed them in case they are open although I think that is unlikely
I am translating the text, I don't quite understand what you are saying about ACOK. The voltage comes from the 6V resistive divider as I understand it.
CMSRC_CHGR has 0V, with and without 4K resistor
I had already done the vast majority of the measurements and checks and I have a lot of experience repairing laptops in the charger section, it has never happened to me that having all these values correctly does not work, especially...

The voltage value without the 4K resistor on ACDRV (PIN 4) is 0V
I removed PQB1 (2n7002) and the input FETs still do not activate. I also measured it and it's ok
If I measure with the oscilloscope at the gates of the input FETs, a peak of approximately 15V appears, and it goes away very quickly in a matter of milliseconds....

Thanks for answering:
I had forgotten to mention these measurements:
2) Pin 4 ACDRV: 0V
3) 19V at drain PQB3, 0V at source PQB3, 0V at drain PQB4, 0V at source PQB4
0V in both gates of PQB3 and PQB4
4) PIN 5 ACOK: 3.23
From what I understand the BQ24800 is not driving the input FETs. I can't understand why.
I have read some of the tutorial, I made the measurements as far as I can understand.
I hope you understand my horrible English, I use Google Translate

Acer Aspire 5 (A515) No power
I friends.
I have a problem that I can't solve. The 19V input voltage does not go beyond the first FET PQB3. If I make a jumper from the input of the charger to the output of the second FET (disconnecting the battery) the laptop turns on. That is to say, the BQ24800 charger IC does not activate the input FETs, when measuring the gates there is 0V. I put the charger IC in another laptop to test and it works, that is, the fault is not in the BQ24800.
I made these measurements on the BQ24800:
VCC on pin 28 ok, it has 18.5V.
Pin 6, ACDET 2.6v, ok...

LA-6755P Rev 1.0
Hello,i need bios file LA-6755P REV 1.0. I know that this bios has already been requested in the forum but the file they uploaded from the main bios has 2049kb, 1000kb is left over and it does not allow me to save the memory correctly. Can someone upload the correct files?

Dell inspiron 3421 that distortion on the screen
Dell inspiron 3421
Mother DNE40-CR MB.
Good guys.
I have this problem with this Dell notebook, it has that distortion on the screen as you can see in the photo. has it ever happened to you?
I present the tests and measurements that I already did:
I tried with another screen and it does the same thing, I also put this screen on another one and it looks perfect.
I checked the LVDS flex that goes to the display and it is perfect
Through HDMI output the image looks perfect
All power lines were measured...

ITE8987E not work
Change the EC ITE8987E because it doesn't turn on when it receives the ignition signal, the 3.3V power line is ok. there was a 30 ohm resistor. When removing the ITE8987E the resistance increased to more than 5K ohm. I changed the EC for the same ITE8787E-BXA, the resistance is not low, however it does not turn on or there is communication with the EC BIOS 25X40, neither is the clock.
Is it possible that it requires recording with a programmer like svod3 or something similar for the EC to work?
I also programmed the EC bios 25x40 with a file that was sent to me over...
