    That's the CPU, but how about the system power draw? HWiNFO gives you that information here:

    It's near the very bottom of the Sensors list for me.

    For some reason my HP battery does not report Charge Rate in HWiNFO

    Hmm. Well then, you could charge up your battery to full, unplug it, and measure how long it takes from full charge to when Windows force-shuts down the system (which is at 5% battery), to find an average value for the power draw—you'd need the total battery energy level (after accounting for battery wear). Power draw, P = battery energy, E ÷ time.

    Does the HP battery report "remaining capacity" (in Wh)? If it does, then you could easily compute the power draw over the course of, say, five or ten minutes with a before-and-after measurement.

    $1000 I paid for my own 7530 it's a good value and I haven't noticed any issues with the replacement laptop yet. 7520 from my company I have over a year works great and it cost around $3000-4000. I personally wound't buy a laptop on Xeon, if I need such performance machine I would pick a desktop.

    @Ionising_Radiation @Aaron44126 I will run this test. To make an even comparison what other settings? So hybrid graphics mode, on battery, running idle. Should I prevent laptop display from turning off? What brightness level should I set for the test? What other settings do you think

    Fingers crossed, preying to the laptop gods that my new 7530 will be problem free.

    One thing I just noticed about your readings here... how does your battery already have 8.5% wear? My HP ZBook G4 is 1 yr 4 mths old and only has 10% battery wear. Do you use the battery heavily?

    AFAIK these batteries have all been arriving with HWinfo reporting wear.
