[DirtyPowerFilter] My CRT monitor has developed a nasty shake/vibration at certain refresh settings, since I moved to a new apartment. I think the problem stems from the old electrical system. Is there anything I can do to "clean" the power and alleviate the problem? Or are all "power conditioning" products bogus? Backstory and more info below the fold. [more inside]

How do you secure a plug so that even if someone yanks on the chord, it doesn't come out of an outlet? It does need to be POSSIBLE to get the plug out sometimes, and it won't work to glue/staple the chord to the wall, because sometimes equipment needs to be moved to another room. [more inside]

The power connector to my G4 Powerbook is almost dead. It only charges in one very specific position, and I have to twist it around for a few seconds to find the sweetspot (rotating it in situ). Nothing is loose and nothing is visibly wrong. I tried squeezing the metal sleeve slightly to make it more elliptical in the hope this would create a tighter connection, but it made no difference.

I am in the process of building an AMD Sempron 2400+ based file storage machine. I am seeking recommendation for how big a power supply I need.
I am planning on 4 to 5 (may be 6 in future) 250GB Seagates, 2x320GB WD Sata drives, 1 DVD writer, Geforce FX 5500 video card.
The $50 case has a stock 480W PSU. I am wondering if I need more juice and possibly something by a well known brand ?
I recently built an Athlon box with Seasonic 430 PSU. Seems pretty quiet. Not sure if I should get another of those.

I opened up my computer and tried to install RAM. After I installed the RAM, my computer would not come back on. I pressed the power button multiple times, and nothing. A friend checked to see if the power button was faulty and it wasn't. It's a Compaq Presario HP and when we plug the power cord in, the power supply just does this clicking. We're not sure what the problem is. I tried a new power cord and still no luck! Any ideas?

Hey, is it better to keep an external hard drive plugged into and constantly running, or is it safer (for archiving and the health of the drive, avoiding power failures that might otherwise zap an entire machine, etc) to only turn it on and connect it when you use it? Thanks as always for your thoughts.
