Power consumption of laptop on standby
I have just received my in car charger from laptopshop.co.uk, very impressed shipped within a day and only £50. And i just tested it in the cigarette lighter and it actually works, all good.
The question i have when hard wiring the charger, do i wire it up so that it comes on ignition or stays on permanently, i guess i dont know how much power the thing will consume when running in standby? Will say in 5 days will it have flattened my battery?
The other question, is which wire will be which on the charger, i havent split it yet, but will it be obvious which is positive and which is negative?
Thank you all for your support getting there, my lcd will be here soon from armen :) Cant wait.
Re: Power consumption of laptop on standby
If you got a voltmeter that handles bout 5 amps you could split the wire, go into standby, and remove the middle wire, then connect the meter, see pic. this is to not break the meter if it cant handle non-standby power consumtion.
the peg in the middle is plus, and the contacts on the sides are neg.
