X22 and 72W power supply

[smugiri]

I have a 72 watt power supply for my wife's old R31.

Can anyone tell me if this 72 watt supply will work with her new X22?

Will it blow stuff up in the X22 -> make it throw some smoke? Maybe a "BANG" type noise to keep things exciting at home?

Or will things be hunky dory.

This page says it will but I want to be sure

Do I have to stick with the 54w supply and avoid the 72w?

If volts , amps and tip matches, tip neg sleeve > pos tip or visa versa you should be good to go, but there has been much discussion about power supplies and i'm one of those who don't recommend it if there is a mismatch in any variable.

Just my three cents, don't beat me.

If everything checks out fine on it, I would go so far as to say it would work just fine. The way I remember things is this, X.T.R.A; that is, the power adapaters/bricks for the T4X Series will work with the R Series works with the X Series works with the A Series...At least that goes for the standard 72W Adapter

Thank you all for the info.

We want to do exactly what Lenovo suggests on the the site, just drop off an adapter / base unit at all the places where she uses her laptop - at work and at home - so that all she has to carry around is the actual laptop. She stopped carrying her old R31 around since she felt it was just too heavy. Having multiple adapters and the much lighter & smaller X22 will mean less weight for her to carry.

I remember when a friend of mine came up from SoCal and *forgot the power adapter* for his X40. So we went through the pre-requisite panic, wondering what to do. Until I remembered X, T, R, A for some reason. We had an extra T4X Series Power Adapter lying around and I thought "Why not?"

Plugged it in and, ta daaa, it worked just fine; no problem. No overheating, charged both the battery and powered the X40 just fine.

These questions keep coming up. For all those who are reading:

You cannot push power; you can only draw it. So a number of X's (I had an X22 once) use 56 Watt adapters (16V). On these machines, you can use the 72 Watt adapter (16V).

But you cannot safely use a small 56 Watt adapter where the machine (a T, say) uses the bigger 72 Watt adapter. Using a smaller adapter can cause overheating and undervoltage.

If you have ANY doubt, use ONLY the adapter specified for your machine.
