 Pravila foruma: Klikni tukaj za prikaz pravil na forumu

  1. Naslov teme mora vsebovati: proizvajalca naprave, poln model in kratek opis okvare.
  2. Sporočilo teme mora vsebovati: oznako tiskanega vezja (v primeru popravil strojne opreme), razširjen opis okvare, kaj je bilo preverjeno, zamenjano in/ali izmerjeno, sklep in vprašanje. Če ne morete najti oznake tiskanega vezja, morate prebrati TO TEMO. Če še vedno ne najdete oznake, prosim objavite kakovostne fotografije obeh strani matične plošče - potrebno je odstraniti vse folije in module, ki bi lahko zakrivali te oznake.
  3. Pred objavo nove teme, preberite vse teme v podforumu USPOSABLJANJA, in naredite predhodno diagnostiko na podlagi vsebine teh usposabljanj.
  4. Nalaganje celotnih navodil/shem, BIOS / firmware datotek, ali objavljanje povezav, ki vodijo do drugih spletnih strani s takšnimi datotekami, je SROGO PREPOVEDANO. Lahko objavite le majhen del navodil/shem, ali povezavo na BIOS datoteko v podforumu NEVERIFICIRANE DATOTEKE BIOS/EFI. V eni temi ne smete objaviti več kot eno stran navodil/shem. Datoteka ne sme vsebovati vidnih žigov "zaupno",, e-poštnih naslovov ipd.
  5. V eni temi lahko opišete SAMO eno napravo. Za vsako drugo okvarjeno napravo morate odpreti novo temo.
  6. Zahteve za sheme, boardview, fotografije matičnih plošč, datoteke BIOS-a ali servisne priročnike za storitve NISO DOVOLJENE. Če želite vprašati za katero koli od teh, odprite novo temo v podforumu ZAHTEVA ZA DOKUMENTACIJO & DATOTEKO BIOS/EFI.

In the Bios is possible to identify SSD M2
After booting by an USB with OS when it ask where install OS SSD M2 is not recognised
How can I solve?

Go into BIOS and turn AHCI mode for SATA\PCIe devices - then You do not need any drivers

If You want to use RAID or Intel Optane then there is option for RST/IRST in BIOS. If You have it choosen, then You need to download driver for the disk controller from laptop manufacturer site to have it visible during installation.

This is the link to manual: https://www.msi.com/faq/notebook-1995

Ok
But now SSD M2 is recognized by the bios but boot with a OS USB when it ask whrere install OS no one SSD is recognized
Is it possible to flash bios?

"Go into BIOS and turn AHCI mode for SATA\PCIe devices - then You do not need any drivers"

ok I will try

You do not need to flash anything. If you choose in BIOS to use the VMD/RST/IRST mode, then the Windows installer needs the additional driver to "see" the disk with the use of this controller. This driver is not a part of Windows, it is provided by Intel most often or AMD.

In AHCI mode you do not need to install driver, but also you cannot use VMD/RST/IRST functions such as RAID, Optane memory etc.

In meantime the Machine shut off.
No mosfet issue.
With PSU connected I get 3,2V instead of 19,5
No power on with battery too.
Now motherboard is inside, I have to pull it out it again.

I have pulled out the mobo but no clear signs of damaged components
Connecting PSU always 3,2V

Measure the voltages to ground on pins 1, 4, 5 of transistors PQ23, PQ30.

#27 Re: MSI PULSE GL66 motherboard MS 15811 ver: 1.1 charging issue

Napisal/-a valieromarco • 31 Januar 2025, 17:08
PQ23
PIN 1= 415 k ohm
Pin 4= 177 k ohm
Pin 5= 408 k ohm

PQ30
Pin 1 = 40 k ohm
Pin 4= 270 k ohm
Pin 5= 408 K ohm

19V Line change from 4,30V to 2,65V continuously

I asked about the voltage measurements, not resistances.

Sorry

After plugging PSU voltages are fluctuating.
After 5 min.

PQ23
PIN 1= 3,15V
Pin 4= 1,32V
Pin 5= 2,90V


PQ30
Pin 1 = 2,45V
Pin 4= 2,40V
Pin 5= 2,90V

Inject 1V from the laboratory power supply to any pin of resistor PR330. What electrical current flows from the laboratory power supply in this case?

If the current consumption is low (in the mA range), rise up the voltage to 3V and check the electrical current again.

1V=0A
3V= 0A

The power supply you used to test the laptop is very likely damaged. Test the machine with another power supply.

Hello
Was the connector of laboratory PSU
Now pc works again but I will keep it on for two days to try it and before closing the topic.

Ok I tried it for 2 days
Thank you so much for helping.
