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

[RdeveLabs]

To all the members here...

Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But at that time my laptop was still difficult to turn off, I tried to press even longer and finally I managed to force my laptop to turn off.

Now after that incident, the problem came to me. Suddenly, when I wanted to turn my laptop back on....
AND YEAH, MY LAPTOP WON'T TURN ON ANYMORE...

After that, I immediately opened the back cover of my laptop and now I don't know what to do? (Because I'm really a beginner technician who wants to learn to fix my own laptop). I'm sure the members here must know what problems I'm experiencing and don't hesitate to give solutions to the problems that afflict me.

think this is the problem what is it? is there a short circuit? if there is a short circuit how do I check it? is there damage such as a corrupt bios? please tell me how to solve it.

I appreciate all your answers that have helped me solve this problem.

Hi. According to your description, I assume, it is bios related ( maybe there was windows update running in background? ). To be sure, measure voltages at all coils, and post here a picture with measured values. Also add the board number of your mother board.

The coil you are referring to is a conductor?

[YellowJacket]

I believe, you meant `inductor` ( conductor is basically every conductive part of the circuit board ), and then yes, measure voltages at all inductors. It is the best place, where you can measure voltage of a switch mode power supply, because you just can't miss it.

oh yes, that's what I meant..okay I'll try to measure the inductor and post all the measurement photos here.

Hi, I have finished checking all the inductors, I will attach the measurement results below.

does that indicate a short circuit?

[YellowJacket]

Well, next time better do one picture ( or two, if there are coils also on the other side of the board ), and write measured values on the picture ( like for example here, in my thread ). What is more important, don't use diode mode, but switch to resistance measurement. You also forgot to mention the board number.

Btw, do you have any programmer for flashing bios?

oh I see, I apologize..I forgot to tell you the board number I have.

Board number: MS-16R61 VER 2.2

I measured the incoming voltage around 20v then the voltage of 5 and 3 volts also appeared, but when I checked using a power supply at 20v, the ampere value did not move at all aka 0 ampere. for measurements using resistance how do you know if something is shorted?

oh yes for the bios flashing tool I have a ch341a programmer, coincidentally I have flashed my laptop bios too, but it still won't turn on.

maybe I attached a photo of the board that I have below..oh yeah I'm also really confused because this msi does not have a schematic.

What did you do with the DC-IN Jack?

[RdeveLabs]

What did you do with the DC-IN Jack?

To see the current entering the board. Because I don't have a power supply.

but when I put the charger on, the current calculation value is not there even when I press the power button it still won't come out the current value. but if the battery is installed, the current value will appear. and even then my laptp still won't turn on.

[Sephir0th]

This is a strange explanation. Since it is not necessary to remove the whole port, neither to measure the current, nor to attach wires to PLUS and MINUS. So i'm still somewhat confused what exactly you tried there.

That you are additionally talking in puzzles doesn't make it better. When you state something then try to be as clear and possible and state WHAT exactly you did WHERE exactly. Storiea like "current will appear" neither clarifies what you are doing and why nor does itbhelp the troubleshooting procedure. So once again please, in a structured way.

Okay, I'll explain it, forgive me if my explanation confuses you...


So this laptop died because I tried to force it off and it wouldn't turn back on. I tried to watch tutorials on youtube to see what problems actually occur with this laptop. One of the videos I saw on youtube said to try to connect the power cord to the motherboard and then see if there is any current going into the motherboard. But since I don't have a power supply, I removed the DC jack and modified it with a voltmeter that has an amp meter.


Then I tried to plug the laptop charger into the DC jack and saw the results on the voltmeter. The voltmeter shows a voltage of 19.8V and a current of 0.00A, which means no current is going into the board. Then YellowJacket gave the advice to measure all the coils, and I attached the measurement results to the post above.


So that's why I modified my laptop's DC jack. .... Is there anything that's still unclear? I will say and explain if there is still something unclear.

I've seen one of your videos, if I'm not mistaken the first step is to check the power rail line. After i measured the power rails, the voltages appeared 20v, 5v, 3v. and i think this board has nothing shorted. is it possible that this is my bios or the SIO chip that has a problem?


For your information, I tried to flash my BIOS with the new firmware from MSI's official website, but still nothing happened, could this be a problem with the SIO chip?


My SIO chip: ENE KB9548GF2

Indeed, the resistance measurements looking somewhat okay. But for some reason i missed the voltage measurements listed. Are they somewhere?

The EC is per 99% not the problem after succesfully releasing the Enables for the 3V and 5V ALW rails

I'm sorry, if I may ask...where should I measure the voltage? is it on the coil? or on the mosfet around the coil? I'm really a beginner here. I will attach a photo of the results of measuring the voltage on the coil.

for EC it looks like you are right there is no problem because when i install the battery and then plug in the charger then the charging indicator appears. it's just that it doesn't respond when i press the power button.

[RdeveLabs]

Oh yes, when I plug in the charger cable, I feel this chip is a little warm but not hot (I checked with an infrared thermometer around 35 degrees), is this normal?


I have attached a picture of the chip because I don't know what kind of chip it is.

That thing with dc jack was smart, if you don't have that specific schematic use a different one, I will leave you one from a different gf63, not the same cpu, but it might help you. Also find the schematic for the MSI pulse, this has the same 11th cpu, so the power on sequence should be the same.
Now check if you have the 3.3v on the power button and if this is going to ground when pressing it.

woah, thank you very much... This is the first time I've seen a schematic like this, it looks a bit confusing, maybe I need to learn how to read it...

okay about the power button, when the button is pressed the multimeter reads 0v, then when the button is not pressed the multimeter reads 3v. is this normal or is there a short?

Is fine then, as I said look on google for msi pulse schematic and boardview (I can't upload it now), that one has a 11th intel cpu, in the end of the schematic you'll find the power on sequence, with that you can check where are you standing.


*I don't know which multimeter do you have, but is always better to solder needles on the on the tips, that way you can measure small components, otherwise you might end up shorting something, for example to measure the EC you'll need those.
*Be careful, your laptop might have a bios issue, but if not, then is one of those really difficult faults to find, and you don't have enough tools, I ruined a few things because of that back in the day, so be careful friend.

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
