Re: Bad Cap Replacement Help
Well I recieved the Capacitors I ordered from Mouser. I got 10 560uF 6.3v HN(M) by nichicon. I also got 2 2200uF 10v HN(M) by nichicon.
These caps are identicle to the ones I have on the board, should I worry that they might be defective as well? or are the nichicon caps dependable thesedays?
I find it quite funny that 12 little capacitors needed a foot long box with several feet of buble rap to ship in. Anywyas. Let me know any comments you guys have. thx.

Re: Bad Cap Replacement Help
! Considering the morons I am surounded by daily I would be suprised if anyone even here knew what RoHS is. I do simply because when I get a new piece of hardware I pour over its tech specs and have run across the term before. But if anyone here makes a fuss I have a pair of CSA Aproved steel toed work boots a proctologist will become very aquainted with removing from the offender...

Re: Bad Cap Replacement Help
Ok sounds like I will use the solder wick method. I plan on putting slight preasure on one side of the capacitor and simotaniouslly applying heat to one of the leads till it comes out of the hold. then Reversing my preasure and doing the other. Then I plan to clean the holes. This is going to be the hard part, since it looks as if i have to go on a shopping trip and get some solder wick :P
By cleaning the pads i assume you mean the little spot on the motherboard which has solder on it.
Why is it nessisary to clean all the...Leave a comment:

Re: Bad Cap Replacement Help
Hi, I need to get some solder wick if i want to do this "correctly", (Which I do).
My soldering iron is a Weller WP35. But as you can see by the pictures the tip has not been looked after very well. I should probally buy a replacement tip. Any suggestions for tiny work like this?
The solder I have I am not sure of the brand but its solid core. You can see by the pictures the size. Its fairly fine so I think the solder will be ok.
I just used this iron and solder to fix a flash drive that had the...Leave a comment:

Re: Bad Cap Replacement Help
Thank you very informative just the sort of information I was looking for. It's all simple stuff that most people who whork with electronics just know off heart and assume others do as well. Most of it I had a basic idea of but you clarified some key points. I have a bit before my order arrives so between now and when it gets here I have time to study up on everything. One small step at a time, as I assume just busting out the soldering iron and randomly poking away at the board would be a bad thing.......Leave a comment:

Re: Bad Cap Replacement Help
Oh I am just wondering if there is some good general guides to understanding how to identify a capacitor.
Also what are the "important" markings that I should be looking for when I attempt to find a replacement.
(Simply trying to learn enought to be able to identify a bad capacitor, and go about finding a replacement without having to run to the forums for help with every single little thing every time. I have a stack of motherboards which I think have bad capacitors....)...Leave a comment:

Re: Bad Cap Replacement Help
Oh! so this has nothing to do with the internals of the spacing of the plates inside the capacitor. Your talking about the Leads that come out of the capacitor and you soder to a board. DOH! I get it now .. that was defenitlly a homer simpson moment....Leave a comment:

Re: Bad Cap Replacement Help
Hey could someone explain or point me to a good explanation of how to read the markings on a capacitor.
Also, in the descritpion from Mouser for a capacitor what does the 3.5LS mean?
"Aluminum Electrolytic Capacitors - Leaded 6.3volts 560uF 8x11.5 20% 3.5LS"Leave a comment:

Re: Bad Cap Replacement Help
So I ordered a few replacements from mouser for the three HN(M) ones. When they come in I am going to replace the one that is physically showing signs of damage. Test it to see if it works. Then probally replace the other one that possibly has issues as well but has not broken open yet. Then I am going to test it again and if everything works great I might use it for a bit but I will probally replace the other one that has the HN(M) markings since I did order a replacement for it as well. Then I should have a good board with which to tinker.

Re: Bad Cap Replacement Help
Upon closer inspection there is also a 2200uf10v Nichicon marked HM(M) It does not have any physical signs of damage yet, but it is probally just a mater of time before it goes. I dont see any others marked like that. There are some others marked HD(M) , VR(M)....Leave a comment:

Re: Bad Cap Replacement Help
No I am in Canada. I'll keep you informed of my efforts.
I work janitorial at my college here and the janitorial closet also houses the computer services "junk room" they toss lots of stuff out. I asked and policy is if its in the junk pile any student is free to take it if they want. Since I work everyday I can quickly see if there is any new goodies that show up.
This board board is one among several I have pulled out of the junk pile. So if I am able to fix it by replacing these defective capacitors,...Leave a comment:

(Key Think?

Its a HN(M), Sorry I was in a rush typing that out as I was late for work and I missed that bit of info.
This is the orentation of the capacitors on the motherboard.
Looking down on the board. Processor at the top, ram slots to the right.
The capacitors are to the imediate left of the four ram slots. One at the top and one at the bottom.

Bad Cap Replacement Help
Hi, I just aquired a motherboard that was "junked" because it was not working. It posts fine but as soon as windows starts to load it imediatelly powers off. Upon closer inspection of the board the end of one of the capacitors is noticibly buldged out and has some brown buildup. There is another capacitor which has a slight buldge but has not blown out yet. These are the only two capacitors on the board showing any sign of trouble every other capacitor has a different color plastic covering.
The board is an Intel Desktop Board Model E210882
The writing on the capacitor...
