    Would anyone please post your discharge rate when the system is idle? I would also like the spec -- cpu, chipsets, graphic card (if you have one), dimension of monitor.

    Ok, I'll be the first

    Idle, 24W :mad: :mad:
    T1600 (no eist), SiS 671MX, 14.1"

    I don't think this is in the right area. Mods please transfer this if needed.

    Perhaps BatteryMon? I haven't tried it.

    RMClock has a page that estimates the instantaneous discharge rate of your laptop.

    I have these figures for my entire "fleet"; full load only refers to a full processor load:

    E6400, full idle, lowest brightness, P8400 @ 0.9250v: 8W
    E6400, full load, highest brightness, P8400 @ 1.025v: 28W

    D620, full idle, lowest brightness, T2300 @ 0.9500v: 15W
    D620, full load, highest brightness, T2300 @ 0.9500v: 30W

    TC4200, full idle, lowest brightness, Pentium M 740 @ 0.7000v: 7W
    TC4200, full load, highest brightness, Pentium M 740 @ 0.9860: 18W

    Specs in sig for the E6400 and D620; the TC4200 has a 915 chipset, a GMA950, a 12" screen, and a 4GB CF.

    EDIT: To the OP, is that a T1600 as in a Celeron Dual-Core, or a T1600 as in a Core Solo?

    Be real men and get a multi meter & a killawatt thats the only way I would consider accurate, software tools are well known for being inaccurate.

    even built in software that comes with your computer is sometimes wrong, let alone a 3rd party app.

    I have a Kill-a-watt. The problem is that the Kill-a-watt goes in front of your PSU, and inefficiencies in your PSU are going to throw off the numbers. I'm not ready to cut my PSU cable to get a multimeter reading either. I use the RMClock numbers as they seem to more accurately coincide with with what I actually get in run time life my rated battery capacities.

    I have these numbers for the Kill-a-watt too, though:

    E6400, full idle: 11W
    E6400, full load: 31W

    D620, full idle: 18W
    D620, full load: 32W

    TC4200, full idle: 10W
    TC4200, full load: 25W

    The software reads the data from the Li-ion battery's EC. It's pretty accurate or else the battery will explode. :>

    No there is still software involved, the battery does not have a readout its just a battery and then some hardware & software combo decipher it.

    i know that the killawatt is going to take into consideration the psu and thats why you use it so you can get real life power draw figures, the multi meter is for the internal readings.

    even something as simple as temp monitor software is often wrong, it reads data and gives you a number but the data is just raw data and the software assigns a number to it, often times there is a given offset to those values that must be manually applied for those numbers to be accurate.

    Idle; 12,8 W
    Specs are in my sig. The chipset is Intel PM45 + ICH-9M

    a killawatt measures the power consumption of your power supply too.
    This is great to know if you want to know your electric bills.
    But this is useless if you want to know the power consumption and battery life of your notebook.
    You have three options: 1. you measure the power consumption between power supply and notebook or 2. you take the values RMClock or other software gives you or 3. you let your notebook run on battery, idle, until it shuts down, then you calculate the power draw yourself.
    Because we are lazy and don't need an accuracy of 0.01% we can take the values RMClock or other software reports without a problem. I also think they are quite accurate. Because it has to be accurate for the battery controlher to calculate the proper capacity and it also has to be accurate for windows to give you correct estimated battery life times, depending on the load.

    However here are my values:
    Core 2 Duo ULV 1.2GHz U7600, X3100 IGP, 4GB RAM, 12" LED backlit display, 120GB 5400 RPM HDD:

    idle: 6.5 Watt
    normal: between 8 and 12 Watt
    load: around 26 Watt
