Question:
90 vs 65 Watt Power Adapter
Lenovo offers 2 power adapters for the T60. The one included is 90W, but they also offer a 65W adapter on their website.
I travel for work, and live on planes. Has anyone ever had a problem getting the 90W adapter to work on a flight?
Also, why does Lenovo offer the 65W adapter at all? I know that prior Thinkpads were around 70W, but I figure they bumped to 90W for some logical reason.
Any downside to the 65W adapter?

Re: 90 vs 65 Watt Power Adapter
I'm pretty sure the 65w is for the older thinkpads.

No, the 65w is for airplane travel (airplane outlets tend to trip the circuit breaker with 90w). What the downsides are I don't know, so I would just ask Lenovo.

Re: 90 vs 65 Watt Power Adapter
the downside of having a 65w brick is that you charge your battery in normal time, while having a 90w brick makes charging faster.
but take note that the 90w charger runs hotter than the 65w

Re: 90 vs 65 Watt Power Adapter
I think the 65w adapters are for models with integrated graphic solutions, and the 90w adpters are for models with dedicated graphic cards.

It is significantly smaller and lighter. The downside is that it's hotter and it cannot be used with a docking station.
If it indeed is slower to recharge the battery, that is a GOOD thing because the faster a batter is recharged, the worse it is on battery longevity.

Re: 90 vs 65 Watt Power Adapter
The thinkpad charging system is very slow and peaceful for the battery to begin with. Using a 65w adapter when not needed is only going to put a ton of stress on the brick, and possibly damage it in the long term.
My C100 came with the 65w adapter, and if i am charging the battery AND using the laptop at the same time it is horrendously hot.

Yep the adapter is almost a fire hazard LOL
Gee my rig charges really fast (at least for the first 90%)... i wish it was more like a trickle charger, for the battery's sake.

Has anyone accidentally caught anything on fire with the 65W AC Adapter yet?
