MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING

[m1ch43lzm]

Hi,

From the description of the issue, I'm guessing that it was a failed BIOS update through Windows Update, especially if you interrupted it (why does Windows have to force BIOS updates right when you need to use your PC?...)
It could also be a corrupted EC firmware, as it's packaged within the BIOS file but updated separately

there's 2 BIOS versions on the MSI site
https://www.msi.com/Laptop/GF63-Thin...GF63-Thin-11UC
Make sure you download the appropriate one for your laptop, one ends in .113, and the other ends in .313

There's a .pdf with instructions on the BIOS .zip file which says

"EC update continues right after BIOS update. Screen will stay black with power LED light blinking. Do not remove the AC power and wait until the system automatically reboots into Windows system. "

My guess is that you need to find a way to program the EC firmware, or replace the EC with a preprogrammed one for your board

Okay, I will look for the schematic and boardview of the msi pulse.

*It's possible that my laptop has a problem in the bios, but I'm still confused why my laptop still won't turn on even though I flashed the latest version of the bios from the official msi website.

*And yes, it looks like the incident you experienced in the past is what I'm experiencing right now. When I was measuring the voltage, my multimeter probe accidentally got stuck on another component and damaged the tps51225c IC, so I had to replace it ... But that's okay, because I finally know what kind of state the mainboard is in when it shorts, and how to find the damage

How did you reprogrammed your bios? sometimes the ch341 isn't that realiable tbh.
I guess you don't have an oscilloscope, so I would recommend you to build a logical tip, you can make one with two transistor a led and some resistors (i2coffe), this will blink when the bios is communicating (you can measure pin 1 or 2) if it's communicating, even if it's corrupted it should.

Hi man...

I also don't understand why windows always updates suddenly, which makes me very annoyed with it.

For the BIOS file, I think the bios version for this laptop is the one that ends in .3xx. Because I read the readme file for both versions, only the .3xx version says "GF63 Thin 11UC" (I didn't have time to check the previous version because my laptop was already dead). After I reflashed the Bios chip, I tried pressing the power button, but still nothing happened.

I thought my laptop was trying to update the EC/KBC/SIO chip. But according to the instructions in the .pdf file, it says "EC update continues right after BIOS update. Screen will stay black with power LED light blinking. Do not remove the AC power and wait until the system automatically reboots into Windows system." but in fact, after I pressed the power button, the power LED light did not turn on and also did not blink.

Then for EC, it seems that this IC cannot be manually programmed, because I tried to search on the Internet, no one explained that this ENE KB9548GF2 IC (BGA chip) can be manually programmed or not. Most of what I see for ENE chips that can be programmed is the 90xx series. I tried to ask the seller, he said "All customers who buy this chip (ENE KB9548GF2) can install it directly without programming". I'm afraid if it turns out that it's not the EC chip that's broken, I'll try @DeXXter's solution first.

Can I ask? in the picture there is a 33k resistor, plus and ground. I am confused, which one is connected to pin 1 or 2? Which is plus? or ground? or from the end of the 33k resistor? and also does this scheme require how many volts? and where do I install the input power?

Since I don't have an oscilloscope and it's very expensive, maybe this way I can try to find the problem.

The 33k end resistor works as your "probe". You can use a cmos battery as the power supply (+ and -). I made one with a 3.3v ldo ic and used a 5v cable from my phone to power on the thing, that before I got a cheap zoyi oscilloscope.

Now you might need to reprogram your bios before going further, desoldering from the board btw, but using a proper programmer, like the ch341, I've used this cheap programmer in many cases. If you don't get your laptop fixed you might have an issue on the ec and well that's another story.

Alright then, I will try to assemble it. I hope this is just a problem with a corrupted BIOS, and hopefully, the EC is not damaged.

[m1ch43lzm]

For the probe you can solder a sewing needle to the open end of the 33k resistor (scratch/file the coating at the end of the needle to get solder to stick)

From what I searched, ENE KB95xx can be programmed with SVOD4 or Vertyanov (latest version) programmers, haven't found a "cheap" alternative programmer yet, you can check with local laptop repair shops if they can program it
If programming BIOS again doesn't fix it, most likely the EC is not physically damaged, just has corrupted firmware so it doesn't know how to react to the power button being pressed

If you end up needing a programmed ec, send me a dm, I got a good chinese store that sells programmed ec on request (also stuff like cpus and other ics).

Well, thanks for the advice... Later I'll put the needle at the end of the resistor, now I'm waiting for all the components to come, then I'll assemble it immediately.

btw, seriously, can the EC ENEKB9584GF2 be programmed manually? because someone made this post and someone answered that the IC ENE KB9548GF2 does not need to be programmed anymore because it has programmed itself automatically.

Thank you very much, mate. After I finish making the tool, if it's confirmed that the damaged component is the EC chip, I'll try buying it from a local store in Indonesia first. If there are any issues, then I'll consider importing it. I'll update this post once I finish making the tool and checking what actually happened.

From that thread it appears to be the case, only if the EC is blank/new

Googling for KB9548 program I found a post on a Russian forum related to vertyanov programmer, google translated below:

Sergey, hello.
I have the second version of the programmer. I read KB9548, but the programmer read 128kV, and it needs to read 160kV. Tell me how to fix this?
The line is written: MS-15821 KB_pins=40 DOWN RIGHT 05MM KSO3=37 KSI4=21 KSI5=22 KSI6=23 KSI7=24 FLASH=160 CHIP=KB9548

And the reply:

Version 2 of the programmer when working with ENE chips can only read 128kb. The solution is a more recent version of the programmer (v3.x \ successor)

In your case its programmed, but likely with corrupt firmware, so it won't auto program itself from the BIOS chip anymore

Oh, I see. I thought it couldn't be programmed, but turns out it can. The programmer tools, though, are crazy expensive..I can't afford them. And in Indonesia, it seems like no one has figured out how to program the latest version of the KBC/SIO IC yet

First you have to program the bios using a programmer desoldering the bios (ask for a clean bios here on badcaps), if you still have the same issue you can just buy a blank ec, is like 5usd. So maybe it will program itself.In these cases this is the only way.
Making that probe should help, but it looks like you don't have anything on your bios so most probably you'll get no blinking, because for some reason is just not turning on (your multimeter should show some current). I had an acer like your laptop, and the issue was a channel n mosfet on the ec_rst rail (close to the battery in my case) it wasn't measuring like a regular mosfet and I had only 3v/5v ldo and 5v always (inductor). I also thought it was the ec, but it was only that little component. So as I said above, it looks like you got not an easy failure here.

I will try to reprogram the BIOS chip with a clean firmware from MSI's official website. Then, I will check it using the tool you recommended.

By the way, in your case with the Acer laptop, was it exactly the same as what I'm experiencing? Because after checking the schematic for my laptop, I noticed that there is no MOSFET in the EC_RST line.

For my chip, the ENE KB9548GF2 in BGA version is quite expensive compared to the regular version (128-pin). It costs around 18 USD, which is approximately 297,180 IDR

I got nothing, only 5v (and the ldos) the mosfet was not directly connected to that line (that rail had a double n channer mosfet), this mosfet was a link between that double mosfet and the id pin of the battery, it was very tricky, I spent days trying to figure this thing out.
Yeah I saw it's a very expensive, first you should get a ch341, and reprogram the bios.

Oh, I see... Alright, I will program the BIOS chip first. Luckily, all the components you suggested for building a simple oscilloscope have arrived, and now I just need to assemble them.
