i just got 2 killerbee mobo's that are mine to mod.
now all i need are the cases/psu.
time to punish these polymers.

Re: dell 270/280 polymer mods
send me some. A corporate client is giving me 3 complete GX270 systems in trade for fixing a few. I can batter some of those polymers as well.<--- Badcaps.net Founder

Sorry to appear dumb, but those yellow/black are polymer? I thought they were just another brand of electrolytic that I didn't recognize... Vent tops on polymers?Comment

yup the polymer with vents

Re: dell 270/280 polymer mods
we need a sticky on this.
oh and i figured out why the vents are there.
the bung is hard not rubber.probably better to keep out moisture.
yeah i sacrificed a few in the name of science.Comment

Re: dell 270/280 polymer mods
stickied. Looking forward to beating on some of these caps as well

Re: dell 270/280 polymer mods
i have a few of them here (FPCAP RE series) that do have rubber bungs. they've been in a geforce 2, so they're rather old. date code (?) is M 13267.Originally posted by kc8adu"Every normal man must be tempted at times to spit on his hands, hoist the black flag, and begin slitting throats." - H.L.

Re: dell 270/280 polymer mods
Here's the first of the three GX270's I have to test the polymer caps. Funny, I have NEVER seen a Dell GX270 in its case, I've always just had the boards sent to me... Seeing one in its case was like seeing your favorite porn star with cloths on.... HAHA
Anyway, this one will get the Fujitsu ploymers...

Re: dell 270/280 polymer mods
Ok, its recapped. I just wanted to take a second to thank KC8ADU for supplying the polies I needed for this!! Thanks man!!!
The board passed bench testing, and I'll have it back in it case soon and we'll see how she does from there.

Re: dell 270/280 polymer mods
FPCAP stands for "Functional" Polymer Capacitor.
-
As I recall a while back someone in one of the threads tore one apart and discovered they aren't totally dry. There is still some liquid electrolyte going on, it's just damp instead of wet.
-
Sort of a hybrid between an electrolytic and a true solid polymer.
- And so the vent is needed.

For what its worth, the lab rat GX system is back in its case, up and running, clean OS install, and seems to be running solid. I have 2 more of these critters to concoct an experiment out of.<--- Badcaps.net Founder

Re: dell 270/280 polymer mods
just got a report back.
a 270 i polymerized for a mitek cyber saw at a truss plant down the road solved a long term piss off the pope problem.
every 20th or so start cimplicity would either bsod when starting the project,start the saws without any command,or give a string of errors such as setpoint errors,overtravel alarms,e stop ,motor overheat,ect.
since i polyed the board they have not had any errors.
the shop owner tried all night to provoke a fuckup and he failed.
i now have 7 more of these to do.Comment

Wasn't you that tore it apart I don't think. (not sure)
Was an older post. 1yr? ago.
I have a slew of bloated FPCAP's off some gateway P3 boards.
(Which were in my to-do box when I read that old post and is why I remember it.)
So, there is still something in their "proprietary technology" that can make gas. - And so they need vents, unlike 'true' solid polymer like OSCON that don't.
-- Or that's my take on why FPCAP's have vents.
I don't know what they really are. ... "proprietary technology" ???
Fujitsu still calls them Aluminum Electrolytics:
""Fujitsu has released a range of "FPCAP" (~~~), aluminum electrolytic capacitors which offer small-size with low ESR and high reliability.""
http://jp.fujitsu.com/group/fmd/en/services/capacitor/
...
On my pulls the the bloated ones ESR was .02.
Unbloated bounced between .00 and .01 on the meter.
These are RE-SU or RE-S1 and data sheet says .007 for both.
50% of the FPCAPs were bloated on 7 boards x5 FPCAPs caps/board.
You all can do what you want but FPCAPs are not going on my good list.

Hey Willa,
I found the thread where you cut one.
There was another where they spread the foil out.

Re: dell 270/280 polymer mods
the earlier fpcaps would bloat after about 5 years of service due to moisture.
asus a7 series boards had lots of these.
not seen any boards in the p4/athlonxp class with bloated fujitsu's.
i have seen some skywell polys bad on video cards though.Comment

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:
Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.
The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type... -

BIOS password locked Dell Latitude 3440 (Service tag B4HNJX3)
Have extracted the BIN and want to know how to rebuild a clean BIOS
I have come across the 8F8C patcher but not sure if that would work in my case as the service tag ends in 0001.
I tried it and although the log states it patched several mentions of 8F8C in the BIN, I haven't flashed it yet in case such a patch wouldn't work.
Have also tried to extract a clean BIN file from Dell's .exe BIOS updates using 'Dell PFS Extractor', but not confidently; Ended up with a 25MB file instead of the same 32MB...
