the plug wiring is ok and the polarity too, but the voltage is 0,5+
is´t about 2,6%+
which it's the range of voltage (+-) of this notebook?



Don't worry about it. IME these laptop adapters are rarely spot on anyway.
After all, they are calibrated by human beings so a 0.5V error is hardly
going to be critical. Also, over years of use they will probably drift by
that amount anyway. This voltage feeds regulated switchmode power supplies
inside the laptop, so it doesn't have to be deadly accurate. The CPU,
chipset, hard drive etc will still get exactly the right voltage.
