No idea if it uses the same type of DC plug common to the 54W/72W 16V adapters of that time. Googling says the 45W adapter that came with the system is only for the Z50, i1400 and 310 systems:http://support.lenovo.com/en_LK/product ... FAN-3PUQXK
There was a recall in 2000 that affected those laptops:http://support.lenovo.com/en_EG/researc ... IGR-4HT3R9
Looking around for the specifications of the 02K6900 FRU (from the AC adapter matrix) says it's 19V 2.4A, which if true, that may not allow use of the 16V adapters. There's some 02K6900 units listed on eBay.
