An old IBM laptop power adapter was broken and wanted to replace it with a new one. However, it was found that the voltage and current indicated on the adapter were different from those marked in the notebook. Such as pictures, leave knowledgeable friends help take a look at the buy a new adapter according to which voltage, thank you.
The voltage is the same or near. The nominal input voltage of your computer is 16V, and the rated output voltage of the following adapter is 20V, which is different from each other. It can not be replaced. It may damage the computer.
Your laptop power parts compatibility is very good, in a certain voltage range of power supply can be used long, but please note in the notebook whichever is correct
The rated output current of the power adapter shall not be less than the rated input current of the computer. The maximum input current label on your computer is 3.36A, so when you buy the power adapter to buy the output current is greater than or equal to 3.36A, the bigger the better, but the output current of the larger rated power is greater, too wasteful, and very heavy, often slightly higher than the line, stay some allowance.
The polarity of the plug is identical. The polarity of your notebook symbol is in the negative, the adapter of my pictures is not clear what is marked polarity, if you look at symbol and laptops are not the same, it is absolutely impossible.
