Re: "capacitor modding" - literally
Seems like someone will next time use earwax to seal those caps )

Re: What causes voltage regulators to fail?
7805 + 2 diodes should work at roughly 7.5V

Re: Laptop upgrade advice
Use XP
Laptop was 'designed' around it and it will work.
I have a couple of machines similar to that one. Ubuntu is just bloated and runs Gbit nic at 14M/s top. With crashing desktop manager, this thing is useless, slow and RAM hungry.

Re: GA-K8NS kbc (KEYBOARD CONTROLLER)?
5V present on the output does not mean fuse is not blown.

Re: What causes voltage regulators to fail?
Hmm. This circuit might be very noise sensitive. Also 8V is a bit of a strange voltage.

Re: GA-K8NS kbc (KEYBOARD CONTROLLER)?
5V fuse for PS/2 has probably failed

Re: What causes voltage regulators to fail?
Get a switching supply and run 8V from there,

Nah. Probably just from inhaling ammonia fumes.

Re: HV wire
Scrape the carbonised PCB off and don't use hot glue there.

Re: MS-7548 Failed TK Caps
One is for Vcore, the other one for Vtt (termination voltage) (I think)
A single cap would I think work, but there isn't any objection as to fill other places as well.

Re: Suspect Bad PS Apple AcBel API 1PC36
I would personally call it 'a shitty design'
Older AT connectors were MUCH better IMO. Had their own springy connections, like molex connectors have for fans.
Hdd conectors cause similar issues. Floppy drive connectors - never seen one do that.

Re: Suspect Bad PS Apple AcBel API 1PC36
Uff. This is pain then. I've repaired many that way, by squeezing the pins, it however works only once or twice and afterwards it is the same or not worse than before. Problem is that many cheaper connectors just don't have the 'spring' in them - cheap material and will eventually make the connection loose. Best thing to do would be just to cut it off and solder a new one there.
Oh, and if you did notice. You may help it a little by individually pushing the wires inside the connector further down, but that is of no guarantee...Last edited by Pyr0Beast; 05-19-2011, 08:35 PM.
