    La-c701p

    Hi All
    I have a mainb HP LA-C701P which has exploded the mosfet Q30
    and once unsoldered the rubble of the mosfet I found a short to ground of the DRAIN
    not having any serigraphy in the pcb I can't determine the value of this capacitor to which I post the photos, this capacitor is shorted to ground.
    I tried to measure the size of the component and for me it is a 0804 while in the wiring diagram if that turns out to be a C590 the specifications tell me that the component is from the 0402 family

    I ask for help and confirm if the capacitor in that position is the C590 or please someone tell me what it is associated with

    THANK YOU in Advatage

    That is a large cap. To me, looks to be an 0805 smd size.

      it seems to me too, but how do I identify it in the schema eleytrico and associate the value?

        This is a non-polarized ceramic cap.

        Use 1uf (or a bit higher will be ok) 0805 at 6v3 rating.

        Suggest X7R but X5R will be fine. This defines the capacitance over temperature changes.

            Sure. Go for it. It will work fine.

              DDR2 resistor packs... 0804?
              by eccerr0r
              Are those typical resistor packs on DDR2 modules 0804 (2010 metric?) 22Ω x 4?

              Wondering what I need to buy if I can't find a sacrificial board with one... which will be annoying if I only need one, just like buying 1 resistor, except I'd be buying 4...

              bios needed for MSI Modern 15A11M-217xit
              by pippo_one
              Hello everyone
              I have a Msi modern notebook 15A11M-217XIT-GG51135U8GXXDXX
              S/N:K2104N0063855 with mainb ms-15521 rev 1.0....that doesn't start, no LEDs on, black screen.
              I'll start by saying that I don't have the wiring diagram or even a boardview. I can't find it online. I tried to test some voltage in the mainb and found that there are 3.0/3.3 volts and 5 volts. No short found in all pcb
              so I think it has a BIOS problem
              I'll post the bios obtained from the maib...but I wasn't able (to avoid compromising the chip) to obtain the "EC" file...with my "EPZ2023"...

              la-b162p need Bios
              by pippo_one
              Hi
              I have a mainb LA-B162P (cpu i5 + nvidia gpu) which sometimes turns on and after a few seconds turns off and on again as a continuous loop. or it stays on expelling heat from the fan that runs normally, but in both cases always with the black screen both internal and external, sometimes I appreciate a backlight flash for a second in the internal monitor.
              i downloaded the schematic and i went to check all the voltages of the mainb and i'm ok, so i thought it was a problem with the bios ...
              Now I bought a new EZP2019 programmer and I am ready to program the bios, (I have...

              Acer TM8572
              by pippo_one
              Hi everyone, I need help.
              I have an Acer Tm8572 series, to be precise Tm8573tg-434g64mnkk
              installed bios version 1.27
              the notebook now doesn't turn on, but before reaching this point I had problems turning it on, sometimes after pressing the button it would load the Acer logo and then it would turn off.
              I opened and replaced the CMOS battery and from that moment on it no longer showed any signs of life...I got the bios from the CMOS (W25Q16) which I placed...but when I read the EC it tells me it's empty no file read (MIXC25L1606E i /o Nuvoton NPCE781LA0DX )
              mainb...
