    Will my other brand laptop's ac adapter work on my HP dv8t?

    The original dv8t ac adapter rating is:
    Input: 100-240v 2A 50-60hz
    Output: 18.5v-6.5v 120 watt

    The one I plan to use for it now is:
    Input: 100-240v 3.5A 50-60hz
    Output 19.5v-12.3A 240 watt

    Will it cause any damage to my DV8T if I use a this adapter now since my orginal one broke? Thanks.

    While it is within the ~5% 'allowance' for the output voltage, it still has to have proper polarity of the outputs and the correct/proper physical plug.

    How much do you like/love your DV8t? I would tend to buy a new OEM HP power supply if I were you.

    If the power supply you plan to use with it isn't a quality (OEM) product, I would be very hesitant to use it for prolonged use without expecting to be buying a new notebook soon.

    Back up your data either way...

    Good luck.

    Gee, thats pretty pessimistic.

    Backing up data? Really, I don't think thats more important now than any other time. You could probably plug 30v of the wrong polarity and the hard drive would still be OK.

    'niff,

    with your data you can take any chances you like; with others (or my) data, I would rather be called pessimistic than a fool with no data. ;)

    do NOT use a 19.5V power supply on a laptop that's designed to use a 18.5V one.
