Your notebook power part of the compatibility is very good, in a certain voltage range of power can be used long, but still please note on the notebook subject.
With the seller to an output 20V ,, 0.5A IBM single hole power adapter
There are several principles for replacing the power adapter.
1. The voltage is the same or similar. Your computer's nominal input voltage is 16V, and the following adapter's rated output voltage is 20V, the difference is large, can not be replaced, may damage the computer.
2. The plug has the same polarity. Your notebook marked on the polarity of the mark is inside and outside the negative, that the adapter I really can not see what is the polarity of the label, you take a closer look if the symbols and notes on the notebook is not the same, it is absolutely not.
3. The rated output current of the power adapter can not be less than the rated input current of the computer. Your computer marked the maximum input current is 3.36A, then you buy the power adapter when you want to buy the output current greater than or equal to 3.36A, the bigger the better, but the greater the output current that the greater the rated power, too much Waste, and very cumbersome, generally slightly larger than on the line, leaving some margin.
