X61s AC Adaptor issues

2008-12-13, 15:03 PM

Hi I have an X61s

 

I've been looking to buy a new AC adaptor and have been told you have to watch what one you buy as the output can seriously damage your battery/machine etc.

 

The one i've seen is marked as 'FRU P/N 92P1157' now this is listed in the Thinkpad Hardware manual as compatible with models: "Models-CTO, xxA, xxB, xxC, xxG, xxH, xxK, xxM, xxQ, xxV, xxT".

 

A couple of things bother me firstly someone once told me about watching the output of the adaptor, as i bought this machine second-hand i was initially given a lenovo adaptor '90W-20V : FRU P/N 92P1104 with output 20v 4.5amps' now I'm wondering firstly is this AC adaptor safe?

 

The adaptor i want to buy is '65W-20V FRU P/N 92P1157 with output 20V 3.25amps' which I've been told is a sort of travel adaptor because of the smaller size.  Now this adaptor is listed in my Hardware manual, but i do not understand the model numbers associated with it: 'Models-CTO, xxA, xxB, xxC, xxG, xxH, xxK, xxM, xxQ, xxV, xxT' none of these seem to correspond with my laptop: 'X61s 7667-CTO'.

 

Also the difference between outputs with this and the one i have,the one i own is 4.5amps output, and the one i want to buy is 3.25amps output, is this an issue?

 

Any advice please......

Well, for what it is worth, I have an x61s too, bought it new and I received it with the power adapter you mention: 65W 20V. Output 20V, 3.25A.

92P1157 is the correct adapter for your system.   i've highlighted 'CTO' in red to show that this does in fact correspond with your system.

 

all you need to find is the 65W adapter from lenovo.   this isn't a "travel" adapter, per se, but instead the adapter for systems with integrated intel graphics.
