    NEC TOKIN 0E907 Fault in Toshiba L510 Laptop - Can I use any of these caps

    Hi,
    My old Toshiba L510 Laptop which was working fine with Ubuntu 22 Server till couple of days back. But suddenly I got a blank screen with fan spinning and no HDD activity. I tried all options and zeroed to a suspected/faulty NEC TOKIN.
    So I removed the faulty NEC TOKIN 0E907 and want to know if I can use the capacitors I have salvaged from old Motherboard. These caps are from old Mackbook Pro Motherboard and I am not sure if any of these caps will work.
    Can anyone please guide me.

    use the caps from image #1 - they look like polymer.
    unless you have an esr meter - then you can use whatever has lowest esr - but it's still probably #1

      Thanks Great Sage.
      What's cap in Image 3. It has 3 terminals. If I have to solder it in the place of NEC Tokin pads, Do I need to solder the edges of the capacitor to the '+' sides and the center of the capacitor to the center pad .. with a wire ... will it work?.
      Is this capacitor a tantalum type ... tried searching but could not find any info.

        i dont know what that is - are the 2 ends connected together?
        maybe it's a 470pF filter - no idea

            Thanks Great Sage for posting the prodalizer image. Oh Great! then I need only 2x330uF caps on each side ... I initially thought I need to put 3 x 330uF caps on each side for 'Nec Tokin 0E907' .... A bit of relief as I could only find 5 of them (removed from Macbook Pro Pcb - Img.8), and I was literally searching for the 6th piece. I will try it in a hour or so and get back to you.

            By the way the I measured the terminals of the Cap in question (image 6) and also shared an images of both sides of the pcb from where it was removed..May be this will help to find some details on the capacitor.
