Although the AC adapter might be the same on the outside - the message you depends on the ID returned over the 3rd wire / data line coming from the AC power adapter.
Go into BIOS setup, then power section and see what power rating is displayed for this adapter.
There's a 60 Watt and 90 Watt version.
If there's something like "unknown power adapter" the laptop doesn't receive the adapter type message over the data wire.
There can be multiple causes in case an unknown adapter message pops up.
