Make sure it's a DC power supply going into a DC laptop! It probably is but check anyway - some peripherals are AC supplied nowadays.
Check the polarity - if it's wrong it will blow up.
Then check the amps (or watts) that the power supply can deliver - if it's more than or equal to what the laptop wants, you should be OK. If less, then it's the power supply that suffers, not the laptop.
Having checked that, it should be fine - if it was my computer I'd just plug it in.

Probably. The difference in voltage (.5v) is negligable, voltage varies between 110 and 120 in North America and 220 and 240 in Europe. Almost all electrical devices are built to accept slight variations in voltage.
One problem is polarity. Are the positive and negative connections correct or reversed on the universal power supply? If you plug in a power adapter with reversed polarity, you could fry your computer before even turning it on (some machines can protect themselves from this, so you might hear stories saying otherwise).
Another problem is with current. My old Compaq Presario's power supply provides 3 amps at 18.5 volts. You can figure wattage by multiplying volts and amps (3 amps times 18.5 volts = 55.5 watts). So, in my case I would need a universal power supply that is rated for at least 3 amps or 56 watts. Using one that is not rated high enough will blow the fuses in the power supply (if it has fuses) or could cause a fire (if it doesn't have fuses) if you use it long enough.
So, if the polarity is correct and it provides enough current, yes.

You have a few things to consider here....does the universal power suppy have enough amps to run the laptop....if its lower then what the laptop requires it will ruin it....however the amps could be higher and have no effect on it.
Also polarity is important from the universal power supply
And finally check the required output for the power supply AC or DC
If none of this makes any sense then don't try it.
Good Luck

under no circumstances blend powersupply cords. whether they are the comparable voltage. the way they provide capacity is particular to the batter and motherboard. you could short out, burn out, or jolt the entire laptop. often while this occurs the pc is unusable and turns into scrap. sometimes the information on the hd can not additionally be salvaged. I even have labored with desktops for over 11 years. i'm no longer able to tell you the way many situations I even have considered this. people forgetting cords and useing a acquaintances, sharing a cord in a dorm, etc.

no way! get the right one from the manufacturer. no matter what it costs it will be less than replacing your power supply after you fry it.

a simple answer would be .... yes .... 0.5 amps isn't going to make a huge difference and you don't run the risk of any damage to your laptop!
