    Gateway MT 6460 (capacitor?)

    I'm wondering if I should just give up trying to repair this laptop...

    One morning I came to my Gateway MT6460 Laptop computer, and it was turning on and off all by itself in about 10 second intervals. It would not post.

    Well, I removed the IDE hard drive and got the data out of it and into another computer, but in doing so I somehow put a HDD password on it, so I bought a new hard drive (beside the point, but this is why I am reinstalling Vista).

    So, first, I reseated the processor, which got me no results, still not posting and the light blinking. Then I unplugged the CMOS battery and let drain. Bingo, I could post. I went into Bios and reset the bios to default settings and started to reinstall Vista.

    My first try at reinstalling went great, I completely installed the operating system and all of the windows updates. Then it crashed again, exactly how it was like before with the blinking lights and no posts.

    I did the same procedures to reinstall windows again, but this time it would crash within a few minutes or even after resetting cmos battery it still wouldn't work.

    Well I noticed some pretty severe cuts on the aluminum of the heat-sink which even allowed some of the glue holding the aluminum to the heatsink to get through. So I ordered another heatsink/fan (and of course when I got the part, the was a nice dent bubble on the aluminum already, but I'm guessing that's not too big of a deal).

    Well, with the new heatsink fan, the computer worked for about an hour and a half. It crashed when installing windows updates (at a different point of installation then last time it crashed).

    It now behaves the same way it did before, it just keeps restarting itself after 10 seconds or so...

    okay, so I talked to someone he said I maybe have a bad capacitor on the motherboard...

    I don't think it is a capacitor, but it looks like the mobo might be missing a black "thing". Looks like there are 3 black "things" in a column with one missing. See attachment. It also looks like it just attachs to the top of the mobo with a little solder.

    There should be a black "thing" here making a connection, right?

    the mobo labels that connection PC234. It is next to the connections PC265 and PC266. (by the way, the second one in the picture isn't damaged, that sploch on the picture is glue)

    Where do I go to find more information on this? Google isn't helping much. What is that missing "thing"?

    Thank you for your help!!

    Re: Gateway MT 6460 (capacitor?)

    Well, after spending about an hour online, I figured out the PC stands for "power capacitor."

    Forgive my ignorance, but there should be a power capacitor on that connection, right? It's not really a slot.

    The other two power capacitors say "330 758c d" on them.

    Do I just go to radio shack or microcenter and find one and solder it onto the 2 metal connections?

      If I replace with inferior capacitor, Is it No harm to other IC components at all?
      by chth96
      I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
      Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
      It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
      So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
      I know that these capacitor will not last as long as nichicon capacitor...

      How can I test non-polarized capacitor?
      by chth96
      I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
      I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

      And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
      I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

      Is it no harm to replace with capacitor without ripple current rating?
      by chth96
      When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


      Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
      But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
      Rubycon YK DataSheet (b...

      Should I replace polymer capacitor?
      by chth96
      a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
      I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
      Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
      Is this ESR value of polymer capacitor correct?...

      Aluminum SMD capacitor replacement
      by LeBeauLuc
      Hi badcapers,

      I am quite puzzle, I am trying to figure out what will be the best replacement for my SMD caps. Knowing that I have no info on the brand and the specifity of the caps, I am quite unsure about what to use, should I go back to SMD aluminum caps or radial caps? Any recommendation for a SMD type to use?

      I have included a picture with the current ESR on each cap, you can see that some are pretty dangereously out of specs.
