Received a replacement power supply for my Powerbook G4 today. The Apple power supply stats are "Input: AC 100-240V 50/60HZ 1.5A Ouput: 24.5V === 2.65A" The replacement supply reads "Input: 100-240V ~ 2.0A, 50-60HZ Ouput: 15-24V === 4.3A & 75W MAX". Is the new power supply incompatible with my Powerbook? [more inside]

My old laptop blew the motherboard after 3 years of great use (Acer Aspire 5670). I just bought a new laptop (Acer Extensa 5630Z). Can I use the power charger/AC Adapter from my old on my new without doing damage? The new one is rated 19V 3.43A. The old one is 19V 4.4A. (plugs are the same). Long live the hive mind!

I just noticed that my Macbook's battery is running down even though the power supply is plugged in. Do I need a new power supply or could it be something I can fix?

I broke a pin on the power supply to my Lacie external hard drive. Only problem is they have ceased to exist, in stores or on ebay... Is there a generic version that would work, or do I have to get someone to solder the pin back on? [more inside]

Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v?? Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?

Here's a technical question. Will this motherboard work with a G3 (Mac) power supply? Gigabyte GA-6VTXD Also in the motherboard is an AMD Athlon 900Mhz. Is that fast? What's the comparison to Intel chips? I've never really understood the conversion. I thought it would be neat to use an old, unwanted G3 case for something like this. [more inside]

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.
