    I know this sounds crazy, but it actually fits!
    The charger that came with the laptop is really loose, resulting in the laptop not charging most of the time.

    Laptop charger: DC Output: 19V == 3.42A
    PS2 power supply: Output: 8.5V == 5.65A

    Can I use it?

    Thanks in advance.

    I wouldn't recommend it and I would highly suggest just buying either a universal or a complete replacement for your laptop. Most of the time the replacement charger is actually rather cheap.

    different voltage? that is a big no... keep trying and you will end up frying one or another...
    get a universal charger, i seen them in any store that has electronics...

    NO

    PS: Just because my post seems very empty, I will fill it with info, for it to work OK you should check three things:
    1. Polarity: You must be sure the positive and negative are plugged the same in both chargers, eg. Positive outside, negative inside. It is shown in the psu with a very nice symbol.
    2. Voltage: It should be as similar as possible, at least within 5% I would recommend.
    3. Current: It should be equal or greater than the original psu, to avoid overheating.

    No, that won't work.
    If you try, you'll either achieve nothing or fry your laptop, so don't.

    Volts have to match. That voltage difference is going to mess your laptop up bad.

    If you value your laptop and personal safetey, DO NOT USE THAT ON THE LAPTOP.

    The voltage difference is a big one, yeah. But the AMPERAGE is a completely different story.

    Think of electricity like water in a pipe. The wire is like the pipe, the voltage is the amount of water in the pipe, and the current (amps) is the pressure of the moving water.

    You'd be pumping about 5.5 amps into a 3.5 amp device. While there are components in the power board of the laptop to limit the current and voltage, it was not made to take that much current and you WILL fry the laptop.

    And the battery will not die peacefully.


    Long story short,


    DO NOT PLUG IT IN OR YOU WILL START A FIRE

    Those are voltage sources, not current sources.
    They will provide 8.5V, but no current.
    The current is, let's say, a consequence of the internal circuits of the device, and a consequence of applying fixed 8.5V to it.

    The current marking is only the upper limit up to what the power supply warranties it will still work correctly, if the device circuit try to pull more current the PSU may overheat and die.

    The current marking on the PSU is not of a big importance, that is a myth because these are voltage sources, not current sources.
    As long as it is big or bigger it is good, so if your PSU is 19V 100000000000A, it will work perfectly fine.

    Are we talking ps2 with internal of external psu? The ones with internal use a standard two pronged ac cable that you can plug into the power supply of a <65w laptop power supply.

    Sounds like the socket on the laptop itself is damaged and getting another charger isn't going to fix it being loose.

    You are funny. The different voltages are a no-no. I never asked anybody because I noticed and I just knew. Don't do that. :)
