    eazyrog says that his inverter works fine. But, do you manually have to push the on/off switch on the PC itself? That stinks. I just purchased the e-pc 40 and installed Windows XP, but since it has the funky 8 pin power connection, I'm about to sell it since there's no easy solution to startup/shutdown. Not one that I can do myself anyway. Also, how does hybernate work? Can you just turn the inverter off, or do you have to "sign off" before? Thanks.

    e-PC options

    I've got a 40, and I've been looking at getting a 42 for the faster processor. I bought a spare power supply on eBay for $15 that I'll be hacking apart for a DC-DC power supply.

    I've read here that the older models like the one being talked about in this thread have a 19v barrel connector. Laptop cig-lighter adapters work with these as long as they handle enough amps. The best solution would be the CarNetix 1900 since it's made for this type of installation. Thats what I plan on using for my e-PC 40.

    I'd love to find a source for the power connectors cheeper than $15 for a whole power supply...

    Another reason for me using the CarNetix supply is that I'm switching to a mac mini eventually, and that's the perfect supply for it.

    guys guys guys.... i do mostly ask for help usualy, but in this case i am fully capable of solving the power problem. I too have the same unit (p3-933, 256m,20gig,ect).

    yes the power supply unit is a 19v plug it is rated for very low power only uses about 1.5 amps (ive checked with meter). I just bought a dc-dc power supply for a laptop (most never laptops are between 18.5-20v), i found the compaq 3000series (vehicle adapter) is 19volts at 3.5 amps. just get that and your done. cut off the cig-plug and striaght wire. also i just hit the power button which i setup for suspend mode (u could setup for hibernation mode).

    BOOM!!! thats it, quick, clean and cheap (well if u buy on ebay used its cheap new its like 99 bucks), but on ebay i got mine for 30bucks..

    Can't you just upgrade the processor? On that note, are there any Socket 370 Pentium M's for less power consumption?

    Sorry for the thread jack.

    Peace,

    open up the machine and use a screwdriver across the pins that the power button connects to. hope that makes sense.
