[Netbook] Should I use either 3A or 5A with an adapter that has an output of 4A?

[DiNZi]

I borrowed this Netbook from a friend, forgot the power cable at his house. I have the actual adatper that goes from that, into the actual Netbook, I have forgotten the power cable (bit that goes from the adapter to the power socket).

I have 2 power cables that fit the adapter at home, one of them is 3 AMP the other is 5 AMP, the one that I have forgetten is 4 AMP.

Which is safer to use? 3 AMP or the 5 AMP?

Just to note, everything else is the same, the voltage ect.

5A, the amperage of the adaptor is just what it can supply, not what it will. What volts/amps does the netbook specify (it will be on a sticker)?

Thanks for the prompt response but I have checked everywhere and I cannot see the amperage on the Netbook sticker, I can only see 16V on it. The model of the Netbook is Sony Vaio VGN-TT11WN hopefully you can dig up this detail somewhere and advise me, thank you

Sorry if I've sort of oversized it or anything, but just making sure this is the battery from the Netbook. Not much details on there too.
