    POWER SUPPLIES. Advantages and disadvantages between 60 and 90 watt power supply?

    Hello!

    What are the advantages and disadvantages of power supplies for the Thinkpad,
    60 watts on the one hand, 90 watts on the other?
    Which is to be preferred?

    Thanks for every tip!

    Well, the 90 watt power supply is significantly larger. So I would only want this if the small notebook is not enough.
    X220 as the main computer and now not so many other computers

    With many Thinkpads you can still connect 60 and 90 watt power supplies - so I wonder why the selection, why this and not that power supply is preferable ...?!

    Let's say you are running your notebook under full load and your battery is not full, so it has to be charged. Then you have reached your limits with 60W and the battery is not charged as quickly as usual. With 90W you have enough capacity.
    I actually always have a 90W power supply on the docking and take the 60W with me on the go.

    can someone say by chance whether the charging current improves if I would switch from a default 65w to a 90 ???
    currently have 22,000mw on my lenovo ideapad u160. or would I have to fear that the battery will not hold up or that the charging electronics are generally limited no matter which nt is on it.

    60W is significantly smaller and lighter ... especially in the US version with the euro stripe
    90W charges the battery faster, lets the processor clock up even when the battery is charged (otherwise (at least with X6) it doesn't)

    Hello,

    In addition to what has been said, many Thinkpads use the 65 W power adapter on the Thinkpad with out battery (e.g. in the dock) has not reached the maximum processor frequency.

    So my configuration is like the one above: 90 W for the dock, 65 for on the go.
