A question regards to power supply to my b520

Question

i bought my lenovo b520 in the usa(110volts) and brought it to israel(220volts).
on the back of the screen it is written  100-127/200-240.
does it mean that inside the computer there is a transformator between 110 to 220,and i just need to get the right plug?
OR, that i have to purchase a transformtor?
thank you

I would expect it to be universal volage too, but found this in the Lenovo IdeaCentre B5 Safety and Warranty Guide V4.1:
Voltage-selection switch
Some computers are equipped with a voltage-selection switch located near the
power-cord connection point on the computer. If your computer has a voltageselection
switch, ensure that you set the switch to match the voltage available at
your electrical outlet. Setting the voltage-selection switch incorrectly can cause
permanent damage to the computer.
If your computer does not have a voltage-selection switch, your computer is
designed to operate only at the voltage provided in the country or region where the
computer was originally purchased.
Unless the power supply legend actually says 100-240v or a document that came with the machine says it's OK, I'd not plug it in to 220V power.
