  • too stupid to try?

    Well, being that i really don't need this old 500 mhz laptop anymore....(being as i am selling it).........if it doesnt sell within the week I plan on trying to hook it up straight to the cars AC line. I will put a small inline fuse so the thing cant get more then 5 amps or so. The reason I am even concidering this is that the power adapter i use for it says it outputs 10-16v, and 2.2-3.2 amps. Will this thing definatly explode? cause if so, i might think twice.....of course if i do attempt it......i will take a few precassions......wire it up to a fused distrobution block and not have the thing sitting in my car while its on.....and use pretty heavy grade wire.....i'm thinking 8guage as i still have some laying around.

    oh, one more thing, i promise not to attempt this before the end of the week (and if someone buys it first, im not gonna do this)

    Any thoughts?

        what does the bottom of the laptop say - its not amps, its volts
        you need to worry about - it will only draw the amps it needs

        AMPs is like a volume of water
        Volts is like water pressure or how fast the water flow is

        Most laptops use 16v to 20v now days with most 18v-19v
        I have a old 486 laptop that will run from 12v with no power
        adapter at all

                  Actually, your alternator outputs AC (alternating current), it's just retified (made into DC by use of diodes) before your battery.

                    I'd say your hit or miss there. My general opinion is that voltage in the car is not clean enough to power the laptop without causing freezing and potentialy damaging it. There is a reason that most ac/dc converters for laptops are expensive, they do quite a bit of filtering.

                      I have found that some if not all laptops now days
                      will draw a little off the battery to make up for a
                      drop in voltage from the wall plug - The laptops
                      battery acts like a UPS - It may still hurt the laptop
                      - and even if it does work it will drain the battery
                      down and then stop working when the battery is
                      dead - it will not have enough power to recharge
                      the laptop battery - after that, if it still works it may
                      act strange and crash a lot

                      they sell a power adapter for like $30 on ebay
                      its made by Targus its a Auto / Air power adapter
                      its not a inverter - its DC to DC - and most come
                      with extra tips for different laptops

                        And what do the batteries do to make up for voltage spikes?
